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.

In this paper, the authors consider the development plan of shale gas or tight oil with multiple multistage fractured laterals in a large square drainage area that they call a “section” (usually 640 acres in the US). -
Technology has been key to success in exploiting unconventional resources. In recognition of the current significant interest in this field, the upcoming issue of an SPE technical journal will feature peer-reviewed papers on the rapidly evolving suite of technologies for unconventional resources.
-
A marked change from a decade ago, Appalachia, the Permian, and the Haynesville now represent almost half of total US gas production, EIA reports.
-
BP ends a year of speculation as to who will buy BHP Billiton’s much-coveted US unconventional business, transforming its Lower 48 portfolio in the process.
-
Today’s advancements in unconventional technology are worth marveling over, but there is still plenty of room for growth.
-
This paper presents a literature review to determine the engineering challenges and opportunities presented by CBM production in China.
-
The Apollonia tight-gas chalk play is located in the Abu Gharadig Basin in the Western Desert of Egypt. This has long been ignored as a gas play in the overburden, while the Jurassic and Cretaceous oil fields deeper in the basin have been explored and developed.
-
This paper reviews the efforts to exploit CBM resources in Indonesia, the challenges these efforts have faced, and possible solutions that can make operations more efficient and profitable.
-
Saudi Aramco is tapping Halliburton’s expertise in developing unconventional resources to increase domestic gas production, a pillar of its long-term strategy.
-
Wells are starting to come on stronger than expected, which is putting a new emphasis on orginizing all the other ingredients needed for shale production: more rigs, roads, pipelines, water, and sand.
