Abstract Clean out using coiled tubing is the second largest application of coiled tubing after nitrogen kick-off. The advancements in coiled tubing metallurgies to intervene in complex wellbore geometries and precision of downhole simulators to predict on-site scenarios require more efficiencies from end tools that evolved from simple jetting tools to rotating jetting heads. The objective intended in the case studies performed in the Middle East and South Asia was to perform cleanout in scenarios where incumbent tools had failed in the past. The impact of jetting action in cleanout operations decreases with an increase in stand-off distance. It was confirmed from laboratory tests that a standoff of eight times the orifice diameter and fluid velocity of 200 ft/sec is required to remove moderate to hard deposits from wellbores. Conventional jetting tools have a standoff distance of more than 40 times and fluid velocities are below 200 ft/sec thus objectives are often compromised. A new type of fluidic oscillator was utilized in the case studies discussed in the paper. Unlike pulsating effects created by 1st generation of the fluidic oscillators, the SFO type oscillator had triple jetting action namely, Helix jetting, Pulses Jetting, and Cavitational jetting. The result of the clean-out with SFO technology was beyond expectations. It saved cost in all the case studies by an average of 35% if had been performed with incumbent technologies and increased production/injection from 30% - to 250% of the original value. Moreover, it reduced the operating times to two-thirds of conventional operations and increased the efficiency of treatment fluids which resulted in the reduction of waste of additives and extra additives to dispose of excess materials at wellsite. This is the first technology that used cavitational jetting in oilfield services and the first to use aforesaid jetting actions altogether in one tool. The technology adopted in the case studies doesn't have moving or rotating parts, thus eliminating the requirement to pull CT out of the hole for redressing and can perform long operations in one go. It doesn't depend on the centralization of the tool as the jetting effect is passed via kinetic energy through submersed fluids, thus can target deeper depth without limitations of the standoff. It allows a higher flow rate of liquid and gas, thus offering higher fluid velocities to perform an effective cleanout.

_ A pervasive shortage of technical skills is costing the energy sector billions of dollars every year in lost value. One global oil and gas recruiting firm estimated last year that 41% of this skills shortage is due to lack of adequate education and training. So, why are operators struggling so much to acquire and retain a skilled workforce? There are several reasons, but two in particular stand out to us since they have recently emerged within the continuing education landscape. 1. The significant—and likely permanent—headcount reduction resulting from the pandemic. 2. Conditions where technical skill requirements are rapidly evolving due to the clean energy transition and net-zero initiative. The combination of these two new and indisputable realities has created an environment wherein, if left unchecked, the skills gap will almost certainly get worse. A seemingly obvious solution to the skills gap problem would be for energy companies to ramp up their investment in skill development and training. But this ignores the constraints energy producers currently face. For instance, despite current favorable economic conditions, investors remain supportive of the producers’ focus on increasing return on capital vs. increasing their general and administrative (G&A) budget. In addition to the pressure to drive cashflow, a more pressing constraint is time. When I ask upstream professionals whether they feel they are doing enough to upskill in their career, most say no. The reason is usually time, or lack thereof. Today’s positive economics combined with lean operations mean that time for training is extremely limited. Avenues for Learning Suppose the above conditions don’t change. Suppose we will continue to run lean as an industry, and as a result, time and budget for training will always be a problem. What can we do as an industry to reduce the skills gap? What are the available avenues for upskilling? The baseline option is to do nothing. In other words, we can learn by doing. To its credit, a great deal of technological advancement has resulted from this approach. The advantage of doing nothing is that learning will always take place on the job. It could be argued that this is also an efficient option since the learnings from the work are directly applicable to the work. However, this “do nothing” approach carries both cost and risk. Risk comes in the form of mistakes that could have been avoided with proper training. The associated costs can be high and include drilling into a depleted zone or a botched completion. The industry has many examples to draw on where neglecting knowledge- and experience-sharing has proven to be enormously inefficient and costly. An alternative is to insource all training. This is considered to be a low-cost avenue since it relies on using subject matter experts already within the company to teach other employees. Hence, existing stores of wisdom and company best practices can be disseminated with no additional investment.

"In offshore and coastal engineering, metocean refers to the syllabic abbreviation of meteorology and (physical) oceanography" (Wikipedia). Metocean research covers dynamics of the oceaninterface environments: the air-sea surface, atmospheric boundary layer, upper ocean, the sea bed within the wavelength proximity (~100 m for wind-generated waves), and coastal areas. Metocean disciplines broadly comprise maritime engineering, marine meteorology, wave forecast, operational oceanography, oceanic climate, sediment transport, coastal morphology, and specialised technological disciplines for in-situ and remote sensing observations. Metocean applications incorporate offshore, coastal and Arctic engineering; navigation, shipping and naval architecture; marine search and rescue; environmental instrumentation, among others. Often, both for design and operational purposes the ISSC community is interested in Metocean Extremes which include extreme conditions (such as extreme tropical or extra-tropical cyclones), extreme events (such as rogue waves) and extreme environments (such as Marginal Ice Zone, MIZ). Certain Metocean conditions appear extreme, depending on applications (e.g.

ABSTRACT: In the pursuit of net-zero carbon by the year 2050, the PETRONAS Group Research & Technology has executed CO2 storage studies incorporating laboratories results as well as with advanced simulation modelling prior to project execution for a case study in the year 2025. This paper is intended to highlight the advanced two-way coupled geomechanics-dynamic modelling workflow involving rock property updating and simultaneous history match for both reservoir simulation and geomechanics modelling. The purpose of this extensive coupled modelling workflow is to evaluate the potential challenges and risk of CO2 injection and storage including the impact of reservoir compaction towards final CO2 storage capacity, fault reactivation, caprock integrity and final injection limit. Advanced numerical coupled modelling for high porosity and highly compactable reservoir capturing the complex dynamic flow of the actual field conditions is challenging and requires a lot of attention to detail. Integration of the various disciplines such as geomechanics, reservoir engineering, geology and geophysics are crucial for the success of this project. This paper will also highlight the novel workflow, challenges and lessons learnt from the advanced coupled geomechanics dynamic modelling which can be applied in other similar projects. 1. INTRODUCTION The case study field was discovered in 1972 and production started in 1996. It is a carbonate gas field with about 350 ft of hydrocarbon interval and a thin oil rim of about 30 ft in thickness. The porosity ranges from 31 to 40% and extensive compaction has occurred with 700 psi pressure depletion throughout the gas production phase. Therefore, a Global Positioning System (GPS) sensor have been installed since the year 2000 to monitor the seabed subsidence due to field production. As the field has been depleted, it was identified as one of the potential CO2 storage sites which require an extensive subsurface evaluation before field injection.

Abstract Founded in 1919, the American Petroleum Institute (API) has a 100-year history in the development of technical programs, including industry standards, starting with the first standard published in 1924 on drilling thread specifications to ensure safety and interchangeability in the production of natural gas and oil. Since its formation, API has led the development of petroleum, petrochemical, natural gas equipment and operating standards for all industry segments. These standards represent the industry’s collective wisdom on subjects ranging from, drill bits to environmental protection and embrace proven, sound engineering and operating practices and safe, interchangeable equipment and materials. The API maintains over 700 standards, many of which have been incorporated into U.S. state and federal regulations. API standards are also the most widely referenced oil industry standards cited by the international regulatory community. API ensures the technical relevance of its standards by maintaining its status as an American National Standards Institute (ANSI) accredited standards developing organization. As an accredited body, API’s standards program undergoes regular program audits to ensure it meets ANSI’s “Essential Requirements” for openness, balance, consensus and due process. In addition to equipment and operations standards, API has been the leader in the development of standards that support sustainable development and community outreach. As an example, API published its first of five specific shale gas standards in 2009 on well integrity, and subsequently developed standards on water resource management, environmental practices, and well cementing technology. Included in this suite of standard is a new publication on community engagement, which was developed to ensure well operators, drilling and well servicing companies and the communities in where the shale gas is being developed fully understand the important aspects of operations taking place in and around their neighborhoods, towns, and cities. API is also updating its standard on public awareness programs for pipeline operations. Communication about industry’s safety and sustainable development activities supported by the API standards program can help to improve the public perception of the oil and gas industry.
