When methane is found in water wells near an unconventional well, fingers point to fracturing as the likely suspect. But a study of wells in the Utica Shale named other sources. The Texas Supreme Court ruled late in April that the Railroad Commission of Texas, the state’s oil and gas regulator, does not have exclusive jurisdiction over environmental contamination cases, which can be settled in court.
When methane is found in water wells near an unconventional well, fingers point to facturing as the liklely suspect. But a study of wells in the Utica Shale named other sources. In unconventional plays, comparing the effect of different completion designs or well-management strategies on well performance remains a challenge because of the relatively brief production history and lack of long-term field analogs of these plays.
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.
When methane is found in water wells near an unconventional well, fingers point to facturing as the liklely suspect. But a study of wells in the Utica Shale named other sources. Methane monitoring using improved methods is detecting more gas in the atmosphere, increasing the need for better ways to eliminate releases. With the API and a multi-operator group passing separate programs aimed at reducing methane emissions, the discussions on what defines an acceptable level of regulation continues within the industry. Three experts from different sectors discussed the challenge of methane and regulation at the first panel session of the 2017 SPE Health, Safety, Security, Environment, and Social Responsibility Conference–North America in New Orleans.
The Italian operator reported positive appraisal and exploration results from wells drilled some 10,000 km apart. UK operator Trident Energy is entering Brazil while Australian firm Karoon Energy is expanding its position in the country. Both will try to boost output from already-producing assets. Findings from Kayrros suggest the average Permian well is both less productive and more expensive than reflected in public data. Mexican President Andrés Manuel López Obrador is prioritizing investment in Pemex over foreign participation as a means to boost the country’s shrinking oil output.
The shale sector is studying the results of a 23-well experiment in the southeastern corner of New Mexico to learn what the wider implications might be. Researchers from the Federal Reserve Bank of Dallas quantified the economic impact of the US shale revolution for the first half of this decade. The green light for Santos Energy’s drilling program in the McArthur Basin comes after a moratorium on hydraulic fracturing in the Northern Territory was lifted in 2018. Findings from Kayrros suggest the average Permian well is both less productive and more expensive than reflected in public data. Permian Basin operators and service companies met to discuss completions diagnostics, flowback strategies, water management, and artificial lift strategies.
One of the most important environmental issues of openpit mining is the closure of mine pit lakes. This article from Mining Engineering provides an account by Gerry Stephenson, who was chief mining engineer of Canmore Mines and was instrumental in the reclamation of Canmore Creek Mine pit lakes. With oil and gas facing a talent gap in the wake of the Great Crew Change, the industry finds itself competing for young talent looking for innovative, purpose-driven work. How can energy foster the culture of innovation needed to attract the new workforce, and how does it sell that culture? The updated document offers an introductory overview of the broad topics of oil spill preparedness and response and provides signposting and hyperlinks to a full range of materials from IPIECA and the International Association of Oil and Gas Producers. This paper details the methodology adopted to monitor gas-pipeline leakages using distributed fiber-optic sensing, using an optical fiber as a linear sensor to provide valuable measurement information from all along the fiber itself. It is “one of the world’s largest greenhouse gas mitigation projects ever undertaken by industry,” Chevron said in a news release.

This course covers the fundamental principles concerning how hydraulic fracturing treatments can be used to stimulate oil and gas wells. It includes discussions on how to select wells for stimulation, what controls fracture propagation, fracture width, etc., how to develop data sets, and how to calculate fracture dimensions. The course also covers information concerning fracturing fluids, propping agents, and how to design and pump successful fracturing treatments. Learn more about training courses being offered. Current and future SPE Section and Student Chapter leaders are invited to engage and share. Every attendee leaves energised with a full list of ideas and a support network of fellow leaders. Those sections and student chapters actively participating in this workshop have consistently been recognized with awards as the best in SPE. SPE Cares is a global volunteering drive aimed at promoting, supporting and participating in community services at the SPE section and student chapter’s level. On its official launch this year at ATCE Dubai, SPE Cares will conduct a “Give a Ghaf” Tree Planting Programme to help preserve Ghaf’s cultural and ecological heritage. The Ghaf tree is an indigenous species, specific to UAE, Oman and Saudi Arabia. It is a drought tolerant, evergreen tree that can survive a harsh desert environment. The initiative not only aims to hold events/activities at ATCE, but also recognise community service that SPE members are already conducting in their respective student chapters and professional sections. The KEY Club, open daily, is an exclusive lounge for key SPE members. The lounge is open to those with 25 years or more of continuous membership, Century Club members, current and former SPE Board officers and directors, Honorary and Distinguished Members, as well as this year’s SPE International Award Winners and Distinguished Lecturers. DSATS (SPE’s Drilling Systems Automation Technical Section) will hold a half-day symposium featuring keynote presentations on urban automation. This symposium will explore technologies being used in developing smart cities through the automation of their infrastructure, transportation systems, energy distribution, water systems, street lighting, refuse collection, etc. These efforts rely on many of the same tools needed for drilling systems automation yielding increased efficiencies, lower maintenance and reduced emissions. Their knowledge and experience can guide the path being travelled by the oilfield drilling industry.
