A new paper from ADI Analytics examines the circumstances in which natural gas could become an attractive method for fueling oilfield equipment. As operators seek lower water management costs, a pair of studies examines methods and technologies that could have a major impact on treatment and reuse for hydraulic fracturing operations and beyond. As part of a revised strategic plan, the Spanish company says it will invest more than $9 billion on its overall operations by 2020, with much of it going to its upstream business unit. How Has the US Fracking Boom Affected Air Pollution in Shale Areas? In recent years there has been a spike of research to determine what the extent of emissions are from fracked oil and gas wells.
Offshore project execution enhancement ideas are highlighted for debottlenecking, gas-hydrate-induced pipeline vibration, and the design of subsea systems for efficient startup. Water debottlenecking increased oil production by 80% and reduced the infield transfer volume by 62%. Operators are increasingly using existing offshore infrastructure for asset life extension, and developing new marginal stranded fields rather than develop new large greenfields. Subsea processing is an enabling technology in this goal. Lessons learned in debottlenecking a “dirty” triethylene glycol contactor at the ExxonMobil Upstream Research Company’s LaBarge Black Canyon Facility in Wyoming highlight the results of work performed between 2001 and 2004.
Operators in the Permian Basin are looking for new ways to handle the rising volumes of produced water coming out of the region without using saltwater disposal wells. One solution, treatment for discharge, could provide an efficient alternative. Though a best practice for sustainable hydraulic fracturing operations, using nonpotable water creates an environment in which microorganisms thrive. If left unchecked, bacteria can affect the environment and the economic viability of the hydraulic fracturing operation. Market dynamics and costs drive the search for solutions.
The report was written by a steering committee of SMEs with industry input from an SPE summit as well as members from SPE online communities. It is based on discussions and conclusions from the summit and is intended to provide guidance on an industry-wide safety management data sharing program. IoT has become a popular phrase in various industries. For upstream oil and gas operators, an IoT infrastructure may present an opportunity improve quality control on their projects, potentially reducing costs and increasing production. The SPE Board of Directors has realigned the Production & Operations and Projects, Facilities & Construction technical disciplines under one Technical Director. How do mooring systems reduce risks of hurricane damage to mobile offshore drilling units?
The outlook in the UK is a case study of the squeeze facing E&P in other basins where operators are trying to pay to sustain production with discoveries, while plugging and abandoning old wells, all paid for by the lean cash flow due to low oil prices. Subsea inspection/repair/maintenance services have traditionally relied on vessel-based, ROV, or diver operations. In the longer term, identifying significant incremental savings in these operations is not sustainable and an innovative approach deploying digital technologies is being investigated. The deal gives Equinor an additional 7.5% ownership stake in the Njord redevelopment project and associated tiebacks in the Norwegian Sea, and potentially raises Faroe’s value in the midst of a hostile takeover attempt by DNO. Startup comes 8 months after the initial discovery in March, marking the second successful tieback since 2017 to the Beryl Alpha platform in the UK North Sea.
Ashtead Technology has acquired Louisiana-based subsea equipment rental and cutting services specialist, Aqua-Tech Solutions, as part of the company’s international growth plans in the US. Subsea inspection/repair/maintenance services have traditionally relied on vessel-based, ROV, or diver operations. In the longer term, identifying significant incremental savings in these operations is not sustainable and an innovative approach deploying digital technologies is being investigated. ROVs dominate the world of subsea inspections, maintenance, and repair, but as operators work in a post-downturn economy, autonomous systems have become more in demand. Autonomous inspections are possible today, but how can they help with light and heavy intervention?
Ashtead Technology has acquired Louisiana-based subsea equipment rental and cutting services specialist, Aqua-Tech Solutions, as part of the company’s international growth plans in the US. LLOG’s subsea pipeline tiebacks and structures connecting the Stonefly development to the Ram Powell platform are scheduled to be installed in Q3 2019. The decision comes after the company’s discovery of an additional 400 million bbl of oil in place at Atlantis, one of the largest fields in the gulf. The expansion is expected to boost production of the deepwater Gulf of Mexico platform by approximately 30,000 BOE/D. It is the fourth major upstream project to begin production for BP in 2018.
When fracturing slowed last year in the Marcellus, companies holding produced water they did not need for fracturing paid other operators to take it. It provided a cheap source of fracturing water then, and in the future, water trading could reduce the high cost of shipping water. Antero Resources has built a huge plant to turn waste water into fresh water and salt for sale. The $275-million investment in West Virginia is the most tangible indication of how operators in the Marcellus are pushing water reuse. In this work, the authors perform automatic decline analysis on Marcellus Shale gas wells and predict ultimate recovery for each well.
Methane monitoring using improved methods is detecting more gas in the atmosphere, increasing the need for better ways to eliminate releases. The complete paper describes a work flow in which wells and production networks in the Cheleken Block offshore Turkmenistan are automatically modeled daily with steady-state and transient tools and ultimately analyzed by the Cheleken Block Central Data Gathering System. One tech company is using a unique approach to building custom apps for the oil and gas business. The Southwest Partnership on Carbon Sequestration (SWP) is one of seven large-scale demonstration projects sponsored by the US Department of Energy. Newly developed ambient seismic imaging methods provide valuable information throughout the life cycle of an unconventional field.
Will Blockchain Become the New Operational Backbone in Energy? Energy companies are looking to distributed ledger technology—otherwise known as blockchain—to help navigate the complex transactional systems that make up their operations. What is blockchain, and what makes it valuable to our industry? Statoil’s integrated operations center on the Norwegian continental shelf is one of several initiatives operators and service companies have set in motion to improve condition monitoring and maximize production on their assets. The company’s 31 licenses highlight a record-high total awarded during the latest APA round, which is aimed at developing mature areas of the NCS.
