Abstract The oil and gas industry is still in transition due to uncertain oil prices. The lower demand in oil production has become a key challenge for oil and gas companies to drill new wells. To endure the operating expenses, producers are now searching for different advancements for the optimum utilization of the production from their existing wells. Artificial lift systems (ALS) is the most efficient technique to optimize production from the well. The main purpose of artificial lift systems is to maximize production from a candidate well. However, there are many systems applicable to a single well. Hence, the selection and design of a suitable system play a vital role in the cost optimization of the well. The hydraulic lift system is one of the primary lift systems used widely for decades and has always been given successful results, provided the selection and designs are as per the requirements of a specific well to optimize its production. The jet pump has no moving parts and most of the time can be deployed rig-less, which drastically decreases the installation cost and time for the Operator, translated consequently to decrease the well's kick-off time to start flow. This lift system can be installed in a variety of ways depending on the well's conditions and is a very effective method of lifting a well. However, if not planned and executed properly, the lift system will not be cost-effective for the client. This paper is about the installation of a jet pump in a unique method of punching a tubing with no seating and sealing profiles to get communication between casing to tubing annulus, then to install the Downhole Jet Pump along with a Straddle Packers assembly. The well 8D located in northern Iraq was drilled in 2014, mud losses were observed during drilling. The well was producing 50 BBLS every three days (after shutting down two days for pressure build-up. The jet pump was designed for this well, with tubing punch and straddle packer options. Since the jet pump system needs isolated pathways for its three different fluids, two straddle packers were used along with the jet pump itself to provide the sealing and proper pathways for the fluids. The study about the unique installation of jet pump systems will be discussed in detail alongside the field-gathered data to validate initial theoretical designs. The operational procedure and optimization technique for the well is also mentioned for a proper understanding of the whole system. The method used in this well will prove to be an economical option for lifting and producing old wells if there are no communication profiles between casing and tubing annulus.

AbstractIn many oil reservoirs worldwide, the downhole pressure does not have the ability to lift the produced fluids to the surface. In order to produce these fluids, pumps are used to artificially lift the fluids; this method is referred to as artificial lift. More than seventy percent of all currently producing oil wells are being produced by artificial lift methods. One of the most applied artificial lift methods is sucker rod pump. Sucker rod pumps are considered a well-established technology in the oil and gas industry and thus are easy to apply, very common worldwide, and low in capital and operational costs. Many advancements in technology have been applied to improve sucker rod pumps performance, applicability range, and diagnostics. With these advancements, it is important to be able to constantly provide an updated review and guide to the utilization of the sucker rod pumps. This research provides an updated comprehensive review of sucker rod pumps components, diagnostics methods, mathematical models, and common failures experienced in the field and how to prevent and mitigate these failures. Based on the review conducted, a new classification of all the methods that can fall under the sucker rod pump technology based on newly introduced sucker rod pump methods in the industry has been introduced. Several field cases studies from wells worldwide are also discussed in this research to highlight some of the main features of sucker rod pumps. Finally, the advantages and limitations of sucker rod pumps are mentioned based on the updated review. The findings of this study can help increase the understanding of the different sucker rod pumps and provide a holistic view of the beam rod pump and its properties and modeling.

A Well placement is a well-known technique in the oil and gas industry for production optimization and are generally classified into local and global methods. The use of simulation software often deployed under the direct optimization technique called global method. The production optimization of L-X field which is at primary recovery stage having five producing wells was the focus of this work. The attempt was to optimize L-X field using a well placement technique.The local methods are generally very efficient and require only a few forward simulations but can get stuck in a local optimal solution. The global methods avoid this problem but require many forward simulations. With the availability of simulator software, such problem can be reduced thus using the direct optimization method. After optimization an increase in recovery factor of over 20% was achieved. The results provided an improvement when compared with other existing methods from the literatures.

Detecting and quantifying methane emissions is gaining an increasingly vital role in mitigating emissions for the oil and gas industry through early detection and repair and will aide our understanding of how emissions in natural ecosystems are playing a role in the global carbon cycle and its impact on the climate. Traditional methods of measuring and quantifying emissions utilize chamber methods, bagging individual equipment, or require the release of a tracer gas. Advanced leak detection techniques have been developed over the past few years, utilizing technologies, such as optical gas imaging, mobile surveyors equipped with sensitive cavity ring down spectroscopy (CRDS), and manned aircraft and satellite approaches. More recently, sUAS-based approaches have been developed to provide, in some ways, cheaper alternatives that also offer sensing advantages to traditional methods, including not being constrained to roadways and being able to access class G airspace (0–400 ft) where manned aviation cannot travel. This work looks at reviewing methods of quantifying methane emissions that can be, or are, carried out using small unmanned aircraft systems (sUAS) as well as traditional methods to provide a clear comparison for future practitioners. This includes the current limitations, capabilities, assumptions, and survey details. The suggested technique for LDAQ depends on the desired accuracy and is a function of the survey time and survey distance. Based on the complexity and precision, the most promising sUAS methods are the near-field Gaussian plume inversion (NGI) and the vertical flux plane (VFP), which have comparable accuracy to those found in conventional state-of-the-art methods.

Abstract In recent years, we have seen some refined drilling technologies crop up all over the world. These have given rise to implementation of remote centers to work on real time decision making with the wells. While drilling is in process, there are technologies that enable real time transmission of data and voice to and from remote sites, helping in real time intelligent commands and responses. It is hence now possible to form a single team of experts to monitor and control drilling operations. The development of remote operations in the oil and gas industry has evolved over years starting 2004 at different speeds in different regions of the world. For example, it took longer to reach the US land market because of resistance to change at the rig site. The decrease in oil prices in 2014 however, pushed remote operations into existence to reduce cost. Due to challenges such as either oilfield culture, company strategy, human factor, legal factor etc., it was not exactly the "norm". Fast forward to 2020 when the Covid-19 pandemic hit the oil industry into another slump, service companies have been pushed into the remote operations world. To learn with the times, this may be the new norm and maybe an excellent one. Many service companies have successfully performed operations wells globally increasing not only the efficiency of wellsite operations but also contributing to cost optimization and safety. During implementation, it is observed that remote operations are less a technical challenge, and more a value challenge requiring confidence from all stakeholders. In terms of drilling and operational efficiency, the results observed globally are significant, with fewer trips for M/LWD failure, as well as significant reductions in M/LWD NPT while drilling. This paper discusses the implementation of remote operations at global scale, lesson learnt on day-to-day basis, optimization opportunities, business workflow, positives such as business continuity, safety aspect and last but not the least, the environmental impact. The paper also talks of changes and effects of Covid-19 Pandemic on these operations. Remote operations prepare us well for such pandemic and it may be the safer way to operate now on. Also discussed are the keys to successful remote operations and various examples of remote operations establishments throughout the globe. Lastly a SWOT analysis is done to conclude how remote operations will help operators to add more value to operations and show that remote operations is the new future.

Despite debate, the fact remains that the climate is changing. When considering the factors that determine potential financial impacts and losses that upstream oil and gas business could suffer due to a changing climate, the issues may primarily appear to be related to weather and geography. On closer examination, the factors that determine the severity of the impacts and losses are largely determined by the design and interdependencies of the financial and economic mechanisms of risk management. There is an increasing consensus in the insurance industry that the challenge presented by climate change, along with the increasing power of climate models, will result in far-reaching changes to the presently accepted practices of risk transfer. This extended abstract describes the increased power of climate models and the improved understanding of the present levels of under-adaptation when viewed from the position of investors in large-scale and long-lived oil and gas assets in Australia. It then looks at risk transfer models and examines potential limitations that have been identified due to the focus on ad-hoc post-disaster recovery when compared to a cost-effective pre-disaster resilience approach. The extended abstract then discusses how changes in the risk transfer approach could affect the financial aspects of an oil and gas business, such as the cost of borrowing, self-insurance, capital allocation and planning.

Qatar is one of the major natural gas (NG) producing countries, which has the world’s third-largest NG reserves besides the largest supplier of liquefied natural gas (LNG). Since the produced water (PW) generated in the oil and gas industry is considered as the largest waste stream, cost-effective PW management becomes fundamentally essential. The oil/gas industries in Qatar produce large amounts of PW daily, hence the key challenges facing these industries reducing the volume of PW injected in disposal wells by a level of 50% for ensuring the long-term sustainability of the reservoir. Moreover, it is important to study the characteristics of PW to determine the appropriate method to treat it and then use it for various applications such as irrigation, or dispose of it without harming the environment. This review paper targets to highlight the generation of PW in Qatar, as well as discuss the characteristics of chemical, physical, and biological treatment techniques in detail. These processes and methods discussed are not only applied by Qatari companies, but also by other companies associated or in collaboration with those in Qatar. Finally, case studies from different companies in Qatar and the challenges of treating the PW are discussed. From the different studies analyzed, various techniques as well as sequencing of different techniques were noted to be employed for the effective treatment of PW.

The cost effective design and construction of liquid pipeline facilities traditionally necessitates the use of bolted joints as opposed to welds. Some of these bolted joints are frequently disassembled and reassembled as part of regular maintenance, while others are assembled at the time of construction and expected to retain a seal for the lifetime of the pipeline. Consequently, the design and installation practices employed for bolted connections are relied upon to produce the same operational life and integrity as welded pipe. In an effort to ensure that the bolted joints used on our pipeline system are as reliable as our welded joints, we investigated industry best practices for flange assembly and the root causes of joint failure. We have completed extensive research of technical literature, including the torquing procedures used in various industries, and performed field-testing on our own system. Generally we have found that: • Flange assembly failures and concerns about this issue are common in the oil and gas industry; • Practices for tightening flanges are inconsistent; and • To accomplish and retain an effective gasket seal, and thus minimize life cycle leaks, one has to consider many factors, including the amount of torque applied to nuts, the stud and nut friction, the type of gasket used, the size of the studs/nuts/flanges, the type of equipment used for tightening, the calibration of the torquing equipment, flange face alignment, and torquing sequence. Using the results of our investigation, we implemented several measures to enhance both the quality and the long-term integrity of our bolted flange connections. This paper describes the results of our investigations, as well as the practices implemented for flange assemblies required for maintenance and new construction activities.

The business landscape has undergone some significant changes over the last several years. Accompanying these changes has been an alignment of corporate R&D with business goals. This has resulted in significant downsizing of corporate research laboratories and the devolving responsibility for R&D matters to operating sites or business units. The downside of this is that the operations are now more than ever focussing on productivity, industrial relations and other essential short-term profitability-motivated issues. Consequently, the changing environment is creating cultures that value and reward short-term results. This short-termism has important implications to industry and the research community.One of the more successful and cost-effective mechanisms by which Australia can enhance its R&D base and consequent prosperity is through collaborative R&D. The Australian Minerals Industries Research Association (AMIRA), together with its oil and gas Division APIRA, has demonstrated over the years how effective this can be. AMIRA's raison d'etre is to assist the resource industries improve their technology position through collaborative R&D. It achieves this by working closely with researchers and industry to identify areas of common interest, develop research proposals, and seek financial support for these proposals from industry. Once a project commences, the Association administers the financial and reporting aspects, as well as monitoring progress, organising progress review meetings and assisting in technology transfer. AMIRA/APIRA has the track record, the systems and expertise to facilitate and manage collaborative R&D focussing on industry needs.The evolution of the Australian collaborative R&D environment in the oil and gas and minerals sectors has been significantly different. The oil and gas industry, particularly in exploration, does not have a history of strong collaborative R&D in Australia. The reasons for this are varied and can be found in the different corporate cultures between mineral and oil and gas companies.
