Unconventional/complex reservoirs
Disposal wells remain the lowest-cost solution for produced water, but concerns over seismicity and long-term sustainability are accelerating interest in alternatives.
This work applies fuzzy logic, a well-established artificial-intelligence technique, to quantitatively assess connectivity between injectors and producers in a giant presalt field in the Santos Basin of Brazil.
With a strong presence across US shale in the Bakken, Anadarko Basin, Powder River Basin, and the Permian, Continental Resources is expanding into Argentina’s Vaca Muerta shale as the privately held E&P giant pursues international growth.

This paper presents the performance results from one of the waterflood pilots in the Viewfield Bakken. -
A type curve is a quick way to answer a critical question—what does a typical well produce over time in a given place?
-
PipeFractionalFlow, a spinoff startup from the University of Texas at Austin, uses new theories and equations to make modeling complex multiphase flow more affordable. A model recently developed offers operators an “independent and unbiased” way to validate the system and select candidate wells.

This well-established oilfield consultancy explains why 2020 might be a big year for the unconventional sector.
-
Senior Research Scientist and SPE Distinguished Lecturer Ian Walton uses a semianalytic shale gas production model to show that natural fractures, contrary to the intuitive beliefs of many, do not contribute significantly to production.
-
Petronas cancels plans for the development of the Pacific Northwest LNG project in British Columbia intended to take away natural gas from the Montney formation for shipping to Asian countries. Low LNG prices strike a blow to the feasibility of the project.
-
As well-developed shale plays and tight formations mature and decline in production, nontraditional strategies for maximizing production and discovering new resources must be considered.
-
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.
-
With multistage operations becoming the industry norm, operators need easily deployable diversion technologies that will protect previously stimulated perforations and enable addition of new ones. This paper reviews several aspects of the use of in-stage diversion.
-
This paper outlines the key issues that must be addressed from a regulatory perspective in regard to the development of an onshore unconventional-gas industry in the Northern Territory.
