One of the biggest oil bosses in the world has a message for hotshot young tech stars: Trust me, being arrogant won't pay off. Royal Dutch Shell Chief Executive Ben van Beurden said the oil industry's own behavior in years past has eroded its relationship with society. He warned that tech companies could face similar fates and that "the alarm bells are ringing quite clearly." "My company is still trusted in many parts of the world, but we have to be honest--trust in Shell has faded over the decades in western Europe," he said at the Web Summit conference in Lisbon, Portugal. "But, today, it doesn't take decades for trust to fade."

Abstract Mineralogical characterization of mudrocks of the North Lisbon Area, was based on an experimental study including 31 samples collected both from boreholes and outcrops. X-ray diffraction (XRD) was applied to the whole rock fraction to identify the mineral phases present. This technique were specified used to determine the concentrations of clay mineral species as well as feldspar percentages. X-ray fluorescence (XRF) was used to determine apatite and rutile concentrations. Wet geochemical techniques were used to determine the non-clay constituents as quartz, carbonates, pyrite and organic matter. Clay minerals identified in the samples were kaolinite, illite, smectite and mixed-layer illite-smectite and their percentages were determined from less than 2 µm fraction. The mineralogical composition of the samples was recalculated from the data obtained using the laboratory techniques referred to. Furthermore, the distribution of the different mineral phases as a function of the depth in the boreholes profiles were also analysed.

Abstract: Despite utilizing multi-discipline teams in petroleum and service companies, and despite the remarkable abilities of these same companies to produce petroleum in many forms and in highly adverse environments, there appears to be a misalignment between the geomechanics used, and rock mechanics, the latter apparently not used, judging by workshop presentations. Is it possible that this is because geomechanics specialists are not aware of long-available non-linear description of shear strength, for both the fractures and matrix, in NFR and gas shales? Description of the non-linearity has been a goal of many in rock mechanics for the last 50 years, with a well-known start by Patton, 1966 reporting in the first ISRM congress held in Lisbon. His bi-linear strength envelope was an immediate improvement on Mohr-Coulomb linearity, and set the scene for others to improve upon this bilinear description. The 1973 non-linear JRC- and JCS-based criterion of the present author was considered too complex by Byerlee, 1978, who favoured use of a friction coefficient. Shear strength represented in geomechanics remains linear, so is often unrealistic. Introduction Due to remarkable educational compartmentalization, there is widespread use of linear shear strength assumptions in the petroleum geomechanics taught in university courses. This is further applied by many oil companies and oil service companies, actually on both sides of the Atlantic, and indeed even in the Middle East. This is undoubtedly due in part to the application of Byerlee's well-known friction coefficients by Zoback and co-workers at the University of Stanford during the last several decades. The linear frictional strength assumptions are applied to signify probable critically stressed fractures, first in deep wells, later in naturally fractured petroleum reservoirs, and in the more recently exploited unconventional gas shales. Linear shear strength assumptions are also applied to the intact rock, which is usually described by simplified linear Mohr-Coulomb, despite many tens of MPa change of effective stress during the sometimes short lives of the reservoirs. The commonly used Byerlee-type friction coefficient to signify that fractures may be critically stressed, with values quoted typically from 0.6 to 0.85, actually gives no insight into pre-peak phenomena, which include the beginnings of roughness and dilation mobilization, giving potential permeability enhancement in the case of gas shales and critically stressed fracture sets in NFR.
Through use of state of the art tools for flow analysis the aims to establish a methodology to determine the performance of a high speed planing craft both in calm water and in waves. Verification against full scale measurements is conducted. The ability to maintain speed in waves is of great interest -both with respect to added resistance and with respect to safe operation and loads on the crew from accelerations. Full scale measurements and CFD (Computational Fluid Dynamics) were conducted on a Norsafe Magnum 850fast patrol boat. The measurements have been conducted during a boat challenge along the Iberian coast. The challenge was run in advance of the HSBO (High Speed Boat Forum) which was held in Lisbon, Portugal, May2015.CFD simulations at similar conditions to the measurements are used for validation. It is further shown how CFD can be used to expand operational envelopes beyond the point where full scale measurements are applicable. This is especially relevant for the acceleration loads on the crew which is often the limiting factor of small HSC (High Speed Crafts). Pressure loads are extracted from the CFD and are evaluated against the current standards for life boats. Various criteria are discussed and the most relevant are analyzed for the measurement results and the CFD simulation. An operational envelope where the different criteria are combined is suggested.
Abstract Since the formation of the International Society for Rock Mechanics (ISRM) Commission on Underground Research Laboratory (URL) Networking in 2011, we have attended and organized URL-related meetings. During 2013 -2014, the gatherings of Commissioners include the 3 SINOROCK, 47 ARMA symposium, 13 TAUP (Topics in Astroparticle and Underground Physics) conference, 2013 AGU annual fall meeting, 2013 EUROCK symposium, 4iDUST (inter-Disciplinary Underground Science and Technology) conference, and the 8 ARMS (Asia Rock Mechanics Symposium). The 2015 planned activities include the 4 URL Workshop associated with the 13 ISRM Congress. Recent progress in planned heater tests in radioactive waste URLs, designs of large excavations in deep physics facilities, and other underground studies are reviewed in this article. Rock mechanics findings and multi-disciplinary studies are among topics of interest to the ISRM Commission. Heater tests for better understanding of the coupled thermal-hydro-mechanical-chemical processes are of interest to radioactive repository assessments and for other thermal storage and geothermal production projects. Large excavations in physics laboratories are driven by the needs associated with designing and housing next generation of experiments to detect rare events. Some existing physics laboratories are interested to use available spaces for geo-sciences studies, including microbiological research for deep life. We review the progress in these topics and welcome inputs on case histories and planned developments in URLs. The inputs from the geo-engineering and rock mechanics communities are essential for our continuing efforts of the ISRM URL Networking Commission.. 1. INTRODUCTION An Underground Research Laboratory (URL) Workshop was held on September 11, 2011, in Beijing, China, in association with the 12 International Society for Rock Mechanics (ISRM) Congress. This was the 3 URL Workshop, and it follows the 1 URL Workshop on 2003 in Johannesburg  and the 2nd URL Workshop on 2007 in Lisbon. This 3 URL Workshop had 22 lectures in 5 sessions. The ISRM URL Networking Commission was formed after this URL Workshop. In this paper, we reviewed primarily presentations in meetings after the 3 URL Workshop. An early literature review was presented at the 2010 ARMS in New Delhi  of URL activities before the 3 URL Workshop. An overview of the 3 URL Workshop lectures and other subsequent meeting sessions in following years are presented in 2015 in the 13 ISRM Congress . Underground studies have been conducted primarily either to evaluate the capacities of different formations to isolate wastes or to explore resources at depths. Many researches are conducted in sites for radioactive waste assessments to project over geological time scales, for physics detectors for rare event detections, for multi-disciplinary collaborations, and for energy resources productions and for environmental isolations. For the ISRM URL Networking Commission, we use the term URL for any facility dedicated to all these research activities. We focus on recent advances in understanding various processes conducted in URLs. The ISRM URL Networking Commission dedicates to evaluate these studies in various workshops and meetings, including the series of Asian Rock Mechanics Symposia (ARMS), EUROCK annual meetings, regional ISRM-sponsored symposia, American Geophysical Union (AGU) meetings, American Physical Society (APS) meetings, and other topical meetings organized after 2011. We focus on recent advances in understanding various processes conducted in URLs, and on known plans and designs for expansions.
Abstract The paper begins with a brief summary of Professor Müller's formation of the ISRM and the contents of the previous six Müller lectures with their emphases on rock fractures. The geological origin of fractures is described via a deformational spectrum diagram and a matrix characterising the consequences of a sequence of superimposed deformational events. The different fracture frequencies encountered along lines in all directions through a fractured rock mass are explained. The value of computer modelling and simulation is demonstrated through an example of the effects of fracture zones on the distribution of the in situ stress field. The need to establish the validity of computer programs, i.e., that the modelling/simulation, does actually represent the rock reality, is discussed with reference to the work of the DECOVALEX project. Finally, examples are given of the effects of rock fractures on engineering design and construction, from pre-split blasting to caverns. Introduction It is a great honour to have been chosen as the recipient of the ISRM 7 Müller Award and I am grateful to the representatives of the International Society for Rock Mechanics (ISRM) National Groups who voted for me. In addition, I am especially pleased because my working life in rock mechanics and rock engineering has been devoted to understanding the geometry and mechanical properties of rock fractures and rock masses—which were the key subjects that Professor Müller promoted. In the ISRM 50 Anniversary Commemorative Book, Hudson and Lamas (2012), Professor Charles Fairhurst notes that on 24 May 1962, i.e., the day before the constitutional meeting of the ISRM took place in Salzburg, a reporter asked Professor Müller, "Do we know the strength of rock?", to which Professor Müller replied, "For rock tested in the laboratory, yes. For a rock mass, no. This is what we need to determine. This is why we need an International Society for Rock Mechanics". Also, in his Opening Address at the 1 ISRM Congress in Lisbon, Professor Müller, as the then ISRM President stated, "Many experts agree with me that discontinuity and anisotropy are the most characteristic properties of the material rock and that the properties of jointed media depend much more upon the fabrics bond of the unit rock block system than upon the rock material. Therefore any theoretical investigation of that material has to go its own ways, in the same way as the construction material of soils years ago suggested to soil mechanics its own methods, which differ greatly from the way of thinking of technical mechanics".
ABSTRACT: In this study, the maximum water particle velocity, in the internal water duct of caisson structure embedding wave power generator, was investigated by CADMAS-SURF numerical modeling to determine the optimized shape of structure. It was considered that water oscillating turbine could be installed within the internal water duct in caisson structure. In this case, the water velocity in the duct is the main parameter of the turbine's power converting efficiency. Therefore, the maximum water velocity characteristics was investigated in various wave heights and periods on the variation of structure shape, specially OWC shape, the angle and the length of slope in front of structure. INTRODUCTION The oscillating water column is one of the most widely used wave energy converting system all over the world. Many efforts have been made in the research of the wave energy converting efficiency and operating performance as the oscillating water column system. In recent, an experiment was performed concentrating on the effects of several shape parameters of OWC chamber in a view of wave energy absorbing capability (Hong, Shin, Hong, Choi and Hong, 2007) and the integrated system of chamber and turbine for OWC wave energy converting facility was studied (Liu, Hyun, Hong, Lee and Jin, 2010). There are many studies in turbine types and energy converting types including OWC. However, most of OWC wave energy converting types including OWC. However, most of OWC wave energy converting studies are about the turbine of oscillating air in OWC and few attempts have been made on the turbine of oscillating water of OWC so far. Cho, Kim, Kim and Sim (2007) numerically analyzed the flushing effects and the likelihood of a vertical breakwater consist of immersed water channel and water chamber. This could be a research example of water turbine for wave energy converting.
Techbits With global energy demand predicted to grow substantially in the next 30 years, the oil and gas industry will be expected to continue providing the lion's share of future supply. With a theme of "Fueling the Future," the 2009 SPE Research & Development (R&D) Conference investigated the new technologies and energy players required to meet the world's energy needs. Nearly 100 attendees converged on Lisbon, Portugal this year to discuss the R&D disciplines that would ensure hydrocarbons’ role as a major energy source in the coming decades. Major conference themes included: maximizing recoveries from known fields, discovering and exploiting new reserves, unlocking trapped energy molecules, solving water-management challenges, and increasing productivity in a time of manpower and resource shortages. Fueling the Future In the first session, leading scientists and economists framed the challenges that confront the industry in providing sufficient energy supplies for the global economy. John Barry, vice president, Unconventionals and Enhanced Oil Recovery (EOR) for Shell, discussed technology's vital role in extracting more hydrocarbons from increasingly challenging areas, while also keeping costs down and managing CO2 emissions. He estimated that there are nearly 2 trillion barrels of challenging reserves in the form of heavy oil, oil and gas shales, and in Arctic and ultradeepwater regions. Tapping this vast resource will require further investment in offshore satellite developments, power from renewable resources, more smart well completions, and new deepwater and Arctic rig technology. Chief Economist Dave Larson with PFC Energy next reviewed the impact of the global financial crisis on the energy industry. He said that the industry is reeling from a triple blow of collapsing oil price, decline in hydrocarbon demand that may persist for years, and the drying up of new credit availability, all of which will hamper normal business financing and cause some E&P programs to be postponed or cancelled, which has already begun. In the long-term, Larson said that there is no fundamental change to the expected future supply/demand crunch and that this crisis may create growth opportunities, particularly for national oil companies (NOCs). "NOCs with strong balance sheets, solid cash positions, and low debt ratios will be well-positioned to emerge as major global players," he said. Discovering Future Reserves The second session reviewed the new seismic, remote-sensing, and drilling technologies required to discover future reserves from increasingly challenging areas. Gerhard Thonhauser of TDE Thonhauser Data Engineering discussed drilling in extreme environments like desert and Arctic regions, high-pressure and high-temperature reservoirs, and ultradeep geographic targets. He called for an industrywide step-change in drilling efficiency, which can be achieved by developing an ultralight drillstring concept to expand the drilling envelope, drilling more offshore targets from less expensive land-based operations, and by reaching deeper targets with existing rigs. Developmental challenges include material compatibility with hostile downhole environments, hydraulics limitations, and poor wear and torsion resistance.
Guest editorial As a member of the SPE Research and Development (R&D) Advisory Committee, I see numerous colleagues and organizations in the oil and gas industry articulating research needs to meet the challenges of increasing reserves, drilling faster, optimizing production, and more. Some focus on longer-term R&D and consider using technologies normally thought to be outside the upstream exploration and production business. For the SPE R&D Advisory Committee, identifying these challenges is important, as one of the committee's objectives is to encourage R&D and to match providers with users. This is not an easy task to accomplish, and it is even more difficult to measure performance. One solution is to provide a forum where both R&D providers and practitioners can speak and join in the discussion on how to "fuel the future." To this end, SPE will hold its second R&D Conference during 3–4 March 2009 in Lisbon, Portugal, with the theme of "Fueling the Future." The conference follows the first R&D Conference held in San Antonio, Texas in 2007. The first conference brought together attendees from operators, service companies, academia, and a broad spectrum of other organizations to identify and discuss the R&D challenges facing the industry as it seeks to find and produce the next trillion barrels. The second R&D Conference will focus on research areas thought to have significant potential to make material changes in recovery, productivity, and other metrics. One highlighted topic will be "Unlocking the Molecules," which may sound rather chemistry-oriented but is indeed a prominent topic in our industry. I invite you and your colleagues to join us for the second SPE R&D Conference. More details on the conference can be found at . Another way the R&D Advisory Committee has raised awareness of R&D challenges in our industry is through articles in JPT. Several series addressing R&D have been featured over the past few years. I had the pleasure of coordinating a series related to R&D challenges in each of the SPE disciplines, including Production and Operations; Projects, Facilities, and Construction; and Management and Information. Industry leaders in each discipline compiled an exceptional set of issues and challenges to address to ensure that the next trillion barrels of oil will be produced. Some of those challenges included reserves estimation, one-trip well concepts, multiphase flow, stranded gas, and controlling discharges to minimize environmental impact. Research on some of these topics is well documented in SPE journals and conference proceedings.
Abstract Rock Mechanics and Rock Engineering was established as a new scientific and engineering discipline in Lisbon in 1966. Since then, this discipline expanded the initial topics of interest and it has become a major discipline of science and engineering. The recent activities of this discipline involved the nuclear waste disposal problem. However, the decrease of constructions in civil engineering and closure of mines due to environmental concerns worldwide resulted in the decrease of interest to Rock Mechanics and Rock Engineering. Although this discipline is not restricted to purely engineering works and activities, it is experiencing a hard time. This article presents a brief overview of various aspects of this discipline and it discusses the present circumstances and bottlenecks that this discipline is now facing. And then, an outline of Geomechanics and Geoengineering as the new directions of rock mechanics and rock engineering is given and possible extensions to new and existing problems and scientific and engineering applications are pointed out. Introduction Rock Mechanics was born as a new discipline in 1962 in Salzburg, Austria and officially endorsed in the first congress of International Society for Rock Mechanics in Lisbon in 1966 . When one looks at the content of the proceedings of the first Congress, the spectrum of Rock Mechanics and Rock Engineering (RMRE) is very wide compared to that these days. In other words, the more emphasis is given to the applications in civil and mining engineering and the relation of rock mechanics with earth science or geosciences is almost non-existent in the last three decades. The recent decrease of civil engineering constructions and mining activities due to economical reasons and environmental concerns in many countries resulted in the decrease of the interest of academia and engineering community in RMRE. The over-emphasis on the nuclear waste disposal problems, which are only relevant to a limited number of countries worldwide, causes further decreases of the interest of academia and engineering community in RMRE. Rock is the main constituent of the crust of the Earth and its behaviour is the most complex one among all materials in geo-sphere to be dealt by mankind. Furthermore, it contains various discontinuities, which make the thermo-hydromechanical mechanical behaviour of rocks more complex. These simply require higher level of knowledge and intelligence in the community of the RMRE. However, one can find numerous oversimplified procedures handling the various aspects of RMRE and they probably cause the obstruction of the advancement in RMRE. Furthermore, the commercialism of some softwares as an ultimate level of advancement undoubtedly resulted in a further loss of interest of academia and engineering community in RMRE. This article is written with a sole purpose of pointing out some shortcomings, bottlenecks and new directions in RMRE. In other words, the self-criticism in RMRE is now required if this discipline is desired to exist among other major disciplines in decades to come.
