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.
Experimentation reveals that swellable nanogels increase their size faster than expected or produce aggregation leading to serious blocking problems at the sandface. This paper studies if the addition of a surfactant can help improve injectivity. If crude prices, rig counts, and tight oil production demonstrate a stronger upward trend in the months to come, US shale operators may find themselves with more produced water than they bargained for. Water production normally increases as fields mature, and two main ways exist to deal with the produced water. One is to dispose of the produced water into dedicated disposal wells.
But there are several ways that operators and service providers can mitigate this “bullwhip effect.” Completion-System Reliability: Where Have We Been and Where Are We Going? All completion systems should enable the safe and profitable extraction of reserves. To maximize the useful life of the completions system, reliability of components, configurations, and processes should be maximized. Knowledge is at the risk of being lost in the oil and gas industry.
This paper describes a coreflooding program performed with sandpacks at different permeabilities, water qualities, and injection conditions. ProSep’s Osorb Media Systems are providing a unique solution for treating the water coming from chemical enhanced oil recovery operations and removing the dissolved hydrocarbons. Rising oil production in the Permian Basin has created an opportunity for midstream companies to acquire and expand pipeline infrastructure to handle a predicted spike in produced water. The company makes good on a pledge to reduce freshwater use and replenish the fresh water it uses. In a recent acquisition, H2O Midstream will own and operate Encana’s produced-water gathering system in Howard County, Texas, and will expand it to also serve third parties.
Sourcing water for hydraulic fracturing, and disposing of produced water, are constraints and significant cost items in the Permian Basin. Some of the produced water can be treated and reused by using a water life cycle approach.. The $10-billion deal will add liquefaction and export capabilities to the existing facility in Sabine Pass, Texas, according to a Reuters report. Golden Pass currently handles up to 2 Bcf/D of natural gas imports to North American markets. A deal with the UK-based energy and chemicals company could fetch up to $3 billion for ConocoPhillips, which is transitioning out of the North Sea to focus on US shale operations.
Steady-state modeling of an asset requires the work of multiple engineering teams, which often leads to suboptimal facility design. An integrated model using information consistently across the entire asset may alleviate the pain resulting from conventional methods. Researchers from Chevron are looking into a new approach to understand the drivers of polymer hydration. How might this affect the design of mixing systems in the field, and could it affect offshore EOR applications? The contract covers the installation of umbilicals, flying leads, and manifolds for the project, which aims to expand and upgrade subsea facilities for the gas field located offshore western Australia.
Last year, the SPE Board of Directors approved a new 5-year Strategic Plan, a blueprint to provide guidance on how the association can meet the needs and expectations of its members and the industry over the next several years. Late December/early January is the time of year when industry outlooks are announced, revealing company spending plans, oil price predictions, and potential stumbling blocks. The most recent report from the United Nation’s Intergovernmental Panel on Climate Change and December’s international conference on climate change held in Katowice, Poland, show that the world is not coming close to reaching the targets set in the landmark Paris Agreement of 2015. SPE is launching a new online publication and newsletter on data science and digital engineering and a new monthly newsletter on the unconventionals oil and gas sector. Slow uptake of innovation and new technology is an oft-repeated criticism of the oil and gas industry.
Noble’s first row of wells in its massive Mustang project is helping increase the operator’s DJ Basin output, and similar results are soon expected in the Delaware Basin. Devon Energy will be getting simpler and smaller by selling two no-growth assets—gas acreage in the Barnett Shale in Texas and oil sand operations in Canada. Its future is staked on growing oil production in the Permian’s Delaware Basin and three other unconventional oil plays. The Oklahoma City independent has a new-look portfolio and new operational and financial priorities. And now it has enlisted an energy research firm to leverage advanced analytics and machine learning to help get the most out of its assets.
Nonaqueous drilling fluids, such as synthetic-based and oil-based mud (SBM and OBM, respectively), are used frequently to drill one or more sections of a well to reduce drilling problems such as shale sloughing, wellbore stability, and stuck pipe. This paper describes how a technique known as applied-surface-backpressure managed-pressure drilling (ASBP-MPD) can alleviate the limitations of conventional deepwater well control. Three onshore fields in the Emirate of Sharjah, United Arab Emirates, have more than 30 years of production history from more than 50 gas-condensate wells. Since the 1980s, many technical works have focused on improving the ability to detect hydrocarbons inside the riser and safely remove them from the system. This trend gained extra momentum with the advent of systems such as riser-gas handlers and managed-pressure drilling.
