Askeladd Vest is Phase 2 of the Snøhvit gas development, which is expected to see an FID this year. The drop in US LNG exports comes amid a combination of weak demand, ample supply, additional capacity coming on line, and flexibility to cancel US cargoes. A recovery in the energy industry is key to the oilfield water sector in the Permian. But the industry must address issues such as further research, regulatory changes, and technology. Poland state officials said the terminal expansion is crucial to strengthening the country’s energy security by increasing its capacity to receive LNG and gas from European countries and decreasing its dependence on Russia.
The deal follows BP’s divestment of its global petrochemicals business in late June. Designed to be a “living” map, it focuses on the largest fixed infrastructure for crude oil and refined products such as trunk pipelines, refineries, and storage facilities. Supreme Court upholds ACP’s controversial permit to lay pipe under national forest and across two states. McDermott’s completion comes 19 months after it was first awarded. SapuraOMV achieved first production from the Larak gas field in January.
With their gee-whiz—albeit artificial—intelligence, robots may be the industry’s answer to jobs deemed dangerous, dirty, distant, or dull. A test showing that it’s possible to automate the billing process for produced water hauling has opened the door for tracking a wide range of field activities. The industry downturn brought on by COVID-19 has motivated big companies to test practical applications sooner. The complete paper presents a discussion of the use of intelligent well completion in Santos Basin Presalt Cluster wells. The future of intelligent operations in our industry is being driven by advances from other sectors that have been embraced for petroleum applications.
The Powder River Basin has emerged over the past year as the latest source of oil production growth for the Lower 48. Companies ranging from a reborn Samson Resources to US onshore mainstays Devon, Chesapeake, and EOG are now betting on the basin to become a long-term core asset. Colorado’s industry lacks the size, variety, and Wild West characteristics of Texas, but that is precisely why the Centennial State’s oil production is surging to record levels. This paper describes a comprehensive field study of eight horizontal wells deployed in the stacked Niobrara and Codell reservoirs in the Wattenberg Field (Denver-Julesburg Basin).

Extraction Oil & Gas announced today that it has filed for bankruptcy protection in a Delaware court which will allow it to reorganize its debt and gain a fresh start upon its exit. The Denver-based firm was expecting to be cash-flow-positive this year but instead finds itself dealing with significantly lower commodity prices as a result of the COVID-19 pandemic that has slowed the world’s largest economies. Founded in 2012, Extraction said in earnings reports filed in May that it produced just over 38,500 B/D last quarter, primarily from Colorado’s Wattenberg field that lies within the Denver-Julesburg Basin. That same month, Extraction withdrew its 2020 guidance as it missed an interest payment on bonds that do not expire until 2024, triggering a 30-day grace period that allowed the company time to mull its options. Extraction has obtained a $125-million financing facility, $50 million of which is new debt.
McDermott’s completion comes 19 months after it was first awarded. SapuraOMV achieved first production from the Larak gas field in January. The natural gas pipeline is co-financed by the EU, with work beginning immediately. The hunt for global alternatives to store crude oil includes offshore, global strategic reserves, pipelines, rail cars, and trucks. The deferments are the latest actions Shell has taken in response to record low crude prices.
Construction on Mozambique LNG stopped in April due to COVID-19, but Total continues work on the project even amid a $12 Billion shortfall. Financing for the Mozambique LNG project follows engineering contracts awarded by Total in the past few months. Delays and disruptions have stymied project plans in the past few months. How will companies prevent current stresses from morphing into catastrophic issues? Production from Train 3 comes almost a month after reaching its final commissioning stage.
The natural gas pipeline is co-financed by the EU, with work beginning immediately. The hunt for global alternatives to store crude oil includes offshore, global strategic reserves, pipelines, rail cars, and trucks. The deferments are the latest actions Shell has taken in response to record low crude prices. This contract is for the development of the Lambert Deep and Phase 3 offshore Northwest Australia. The court ruling comes less than a month after TC Energy announced plans to proceed with construction of the Keystone Pipeline.

Selecting appropriate proppants is an important part of hydraulic-fracture completion design. Proppant selection choices have increased in recent years as regional sands have become the proppant of choice in many liquid-rich shale plays. But are these new proppants the best long-term choices to maximize production? Do they provide the best well economics?
The paper presents a brief historical perspective on proppant selection followed by various detailed studies of how different proppant types have performed in various unconventional onshore US basins (Williston, Permian, Eagle Ford, and Powder River), along with economic analyses. As the shale revolution pushed into lower-quality reservoirs, the concept of dimensionless conductivity has pushed our industry to use ever lower-quality materials—away from ceramics and resin-coated proppant to white sand in some Rocky Mountain plays, and more recently from white sand to regional sand in the Permian and Eagle Ford plays.
Further, we compare early-to-late-time production response and economics in liquid-rich wells where proppant type changed. The performance of various proppant types and mesh sizes is evaluated using a combination of different techniques, including big-data multivariate statistics, laboratory-conductivity testing, detailed fracture and reservoir modeling, as well as direct well-group comparisons. The results of these techniques are then combined with economic analyses to provide a perspective on proppant-selection criteria. The comparisons are anchored to permeability estimates from production history matching and diagnostic fracture injection tests (DFITs) and thousands of wellsite-proppant-conductivity tests to determine dimensionless conductivity estimates that best approach what is obtained in the field.
Dimensionless fracture conductivity is the main driver of well performance because it relates to proppant selection thanks to the inclusion of the relationship of fracture conductivity provided by the proppant relative to the actual flow capacity of the rock (the product of permeability and effective fracture length), which is supported by the production analyses in the paper. The paper shows how much fracture conductivity is adequate for a given effective fracture length and reservoir permeability and then looks at the economics of achieving this “just-good-enough” target conductivity, either through less proppant mass with higher-cost proppants or more proppant mass with lower-cost proppants, as well as mesh-size considerations.
This paper does not rely on a single technique for proppant selection but uses a combination of various data sources, analysis techniques, and economic criteria to provide a more holistic approach to proppant selection.
