Partners Eni and TotalEnergies have confirmed a major gas discovery in the Cronos-1 wildcat exploration well in Cyprus' deepwater Block 6, 160 km off the island's coast in the Eastern Mediterranean. Preliminary estimates suggest the presence of nearly 2.5 Tcf of gas (70 Bcm) in place with significant additional upside to be evaluated with a new exploration well (Zeus-1) to be drilled next on Block 6, according to separate news releases issued by the companies. Vantage Drilling's Tungsten Explorer conducted drilling operations at Cronos-1. The well encountered several good-quality carbonate reservoir intervals and confirmed earlier data acquisition campaigns that had suggested an overall net gas pay of more than 260 m with excellent permeability. Cronos-1 is the fourth exploration well drilled by Eni Cyprus and its second well in Block 6. Eni, together with TotalEnergies, drilled its first well in Block 6, Calypso-1, which was hailed as a success in February 2018 after it encountered an extended gas column of rocks of Miocene and Cretaceous age, with the Cretaceous sequence possessing excellent reservoir characteristics.
Partners Eni and TotalEnergies have begun drilling a natural gas wildcat dubbed Cronos-1 in Block 6 offshore Cyprus. The well, originally planned for 2020, was derailed by the COVID-19 pandemic. Vantage Drilling drillship Tungsten Explorer is on location and is conducting the drilling operations. In 2018, the partnership struck gas at the Calypso well in another part of Block 6. That well proved that the carbonate play present in Eni's Zoar field off Egypt extended to the Cypress exclusive economic zone.

ABSTRACT The utilization of recurves on vertical seawalls reduces overtopping without drastic increases in the structures’ freeboard. As part of ISOPE22 blind test challenge, an in-house developed computational fluid dynamics code is used to simulate the breaking of waves on a vertical seawall and the interaction of the violent up-rushing flow with the recurve. The code combines recent advances which speed-up the solution of Poison's equation, with an immersed boundary method and a Large Eddy Simulation model. The comparison of the numerical results with the experimental data provided by the organisers shows a satisfactory reproduction of the wave conditions in the flume and a non-negligible underestimation for the predicted peak pressures. This, with a computational cost of approximately 2 hours per wave period. INTRODUCTION During storms the interaction of waves with seawalls often leads to green water and impulsive overtopping. Recurves placed at the top of the seawall deflect seawards the up-rushing water thereby reducing overtopping without drastically increasing the freeboard. Following field failures with recurves being toppled by the wave action, numerical and experimental investigations on the interaction of such super-structures with non-breaking (Castellino et al., 2021), and breaking waves (Stagonas et al., 2020), have highlighted the importance of accurately predicting wave induced loads. Recent experimental works, e.g. Dong et al. (2021), Ravindar & Sriram (2021a), and Stagonas et al. (2014) among others, highlight a complex relationship between the super-structure's design characteristics and the wave induced loads. For example, chamfered parapets and recurves were shown to experience impulsive loads induced by non-breaking waves, the magnitude of which increases drastically when the waves break at the wall. For the latter conditions, the shape of the recurve was also shown to affect the loading conditions at the wall as well. The present blind test challenge calls for simulations of regular waves breaking on a vertical seawall equipped with a recurve.
The Cyprus energy ministry confirmed a reservoir of high-quality gas was encountered by the ExxonMobil-led Glaucus-2 appraisal well. The drilling of the well was conducted in the area known as Block 10 in the Exclusive Economic Zone (EEZ) that has been challenged by Turkey. The ministry said that operations in the EEZ included production testing. "The consortium will proceed with a detailed analysis and evaluation of the data collected to more accurately determine the qualitative and quantitative characteristics of the reservoir, as well as potential development and commercialization of the discoveries," the ministry said in a statement. Cyprus previously estimated gas resources in the reservoir of between 5 and 8 Tcf when the discovery from the Glaucus-1 well was announced in 2019.
Abstract Engineering Asset Management(EAM) is management of engineering assets and it provides guidelines on the effective usage of all the physical engineered assets within the organization. Similarly, Non-Destructive Testing [NDT] is used as a handy tool for integrity assessment of Assets in scheduled maintenance & inspection program. Though Asset Inspection in Oil & Gas Industry were using conventional NDT methods, now ASME, API and others came up with inspection procedures based on fracture mechanics, where each user to ascertain how their tool/regional operating condition deviate from the assumptions herein, then employ their engineering and technical judgment in deciding how and when to employ any part of these standard. Till recent past, there were no regular validation for these procedures being performed as presumed; benchmark for Severity of failure in North Sea offshore and that in MENA Onshore are set as same. Integration of Operations Management System [OMS] based in Asset Inspection with the EAM allows the Asset Owner/Custodian to consistently monitor each Asset, Acquire monitoring / measurement data in common platform using standardized operating procedures, Measure / Analyze Longevity of each Asset and enable the end user to validate their Service Quality Plan and inspection procedures, as per applicable operating limits and risks. The purpose of this paper to emphasize the importance of optimizing the Asset utilization and serviceability to enhance overall efficiency by integrating; (1)EAM software that manages Assets, (2)OMS controlling the process and (3)Asset Inspection Management System[AIMS]. Case study refer our AIMS, a tool to track all Equipment data [Images, OEM/CoC Document, Inspection Reports/Certificates, track analysis of major attributes] through a single channel - Master Asset [Inspection] Register. Uniquely numbered Assets in each category Drilling Tubulars, Hosting &Handling Equipment and/or Lifting Equipment Item is captured in respective Master Asset Inspection Register with all related Equipment data & Inspection records. Inspection records provides all its inspection related history since its commissioning and manufacturing OEM/CoC Documents. Our cloud based AIMS-App's compliance to API Q2, ISO9001:2015 and ISO17020:2012 ensures its certifying requirements to, (1)relevant Industry standard and bench mark (2)Competence of Inspection Personnel and (3)Compliance of Measuring Devices & Equipment. In last two years [2016-2018] by ensuring Acceptance Benchmark only, more than 70% reduction in premature failure [Crack in Thread Connection; where 50% of those are potential NPT cases] in drilling Tools achieved. Our App provide the user to analyze Inspection data. The trend analysis of tools helps in its planning and utilization plus the data can be directly input to modify Service Quality Plan to optimizing the asset utilization & serviceability. The above are some of the immediate befit to Oil Company and Drilling Contractor by AIMS. This paper also discusses one more dimension of it, Reliability in Service Quality. As this AIMS Tool is synchronized with our, (1)EAM software that manages company's all assets and resources, and (2)OMS controlling the process, the integration of all three increase the overall efficiency of the service and results in profitability of a business.

Abstract Over the past decade, the Eastern Mediterranean has been the prime focus of E & P Companies, mainly attributed to the giant discoveries of Zohr-Egypt, Glaucus-Cyprus and Levantine-Israel involving isolated Miocene-Cretaceous carbonate build-ups and Miocene-Pliocene deepwater clastics turbidite plays. A total of 13 Bboe of proven 2P reserves have been added since 2010. These plays are the focus of exploration. Being located in the center of these giant discoveries and the only remaining unexplored region in the Eastern Mediterranean, the frontier Ionian-Crete has recently attracted the attention of the Oil and Gas industry and concessions have been allocated to number of operators (Fig.1). This study is aimed to investigate the hydrocarbon potential of this basin utilizing an integrated play-based exploration approach. Triassic to Pliocene stratigraphic successions and associated thermogenic petroleum systems and plays have been evaluated and areas of high prospectivity have been identified. A crustal model was built to establish the basin geohistory and to understand the impact of crustal reconfiguration during the Hellenides Orogeny and its implications to the petroleum systems maturity.
Abstract Unconventional formations require advanced mechanical and index assessments to improve their understanding under different geomechanical processes. However, difficulties associated with obtaining cores from the target formations and the challenges with sample preparation increase the assessment complexity. This research compiles data from unconventional index properties and rock mechanical test results from published articles and reports. The parameters include rock mineralogy, rock mechanical properties (compressive strength and elastic properties), and petrophysical properties (porosity, TOC, and permeability). The study showcases the main differences between the global and regional (Middle East and North Africa) rock formations and presents the best analogs for the regional reservoirs. These findings supplement the scarce and complex procurement of the needed rock specimens and reduce the number of core samples required for detailed evaluations. These outcomes help reduce the costs (equipment, sample preparation, measurement time, and the number of specimens tested) associated with the unconventional rock experimental evaluation. In addition, this study explores the successful development strategy implemented in the unconventional reservoirs in China to accomplish commercial production and recommends appropriate rock analogs for detailed experimental evaluations. This paper is part of an in-depth literature data compilation of MENA regional and global unconventional formations. This section of the study focuses on the target unconventional formations of Saudi Arabia and the unconventional formations in China, the USA, and Canada.
Abstract Modern Society followed, and it is still largely following, a linear process for natural resources utilization: raw material extraction, goods manufacturing, use/consumption, waste generation. Such a model is proven to be not sustainable because it cannot go forever considering the limited quantity of available resources on Earth but also because of waste and process by-product management. A multitude of diverse initiatives to change this process started at different levels and within several industries in the last years including the O&G sector. Most of these initiatives share the same principle of "regeneration": waste and materials represent, in this view, the "feedback loop" able to make the production process a circular process, instead of an open-end one. Eni promotes and supports different initiatives to implement the principles of a Circular Economy and the objective of this paper is to describe a process implemented within Eni aimed at reducing the footprint of the Oil and Gas Industry with reference to material usage. Surplus and damaged materials are no more treated as waste, but they are re-engineered or re-conditioned (if necessary) in order to be redeployed to other projects within Eni affiliates all around the world. Nowadays this process is well structured and formalized within Eni and it is extensively applied involving all worldwide affiliates, reducing the overall CO2 footprint. Results achieved within Eni, in the last few years, averages between 6,500 and 17,500 ton of steel of material redeployed among Eni's affiliates for a value ranging between 26 and 71 million USD. The overall average result is 23,000 CO2 equivalent ton not released per year and 242,000 GJ of energy saved (ref. to steel manufacturing estimated impact:1.9 ton di CO2/ton steel cast and 20 GJ/ton steel cast). Extending this process to involve material and equipment manufacturers, it is possible to improve the whole supply process reducing at the "source" the material storage needs, the material surplus and the produced wastes, including the CO2 emission produced in the transport phase. Initiatives like "Just in Time" delivery and material "Buy Back", mainly applied in Countries where Framework Agreements are already in place between Eni and its manufacturers and where manufacturers have their production sites and other facilities, are essential to achieve this target. Eventually, applying the approach to the whole supply chain and operations management will allow to reduce the "last mile" warehousing and transportation needs, including the dimension and capability of the operations fleet.
