Unconventional/complex reservoirs
This year’s selected papers showcase meaningful advances across condensate‑rich tight gas, tight sandstones, and coalbed methane reservoirs, each contributing new tools for improving predictability and field-development efficiency.
This paper presents a novel approach to predict reservoir porosity by conditioning seismic data, calibrating seismic impedance inversion, and tailoring rock-physics analysis.
This paper presents findings reinforcing the argument that acid fracturing is a strong alternative stimulation method to improve productivity in the Austin Chalk formation.

The complete paper describes a physics-based model of interference and a sensitivity study to propose guidelines for well spacing and a drilling timeline for multiple horizontal wells in the Vaca Muerta shale. -
A fracturing test site in West Virginia has quietly made a data trove available on the website of the Marcellus Shale Energy and Environment Lab.
-
Using maglev technology, a new artificial lift system seeks to boost production output by sucking down reservoir pressure from inside the wellbore and from inside the reservoir.
-
Production from the Vaca Muerta now accounts for 23% of Argentina’s natural gas output. With only 4% of the shale play’s acreage in development, the US EIA says the country is in position to boost LNG exports in the coming years.
-
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.
-
The Unconventional Resources Technology Conference is like visiting an oilfield theme park for engineers and geoscientists. This year those traveling to the conference for a glimpse of what is possible in exploration and production will also focus on ways to improve short-term profitability.
-
The UK shale operator will move forward with fracturing and testing its second well at its Lancashire site despite strict constraints on induced seismicity that hampered fracturing work on its first well.
-
The combination will create one of the Haynesville Shale’s top gas producers, tripling Comstock’s Haynesville-Bossier acreage.
-
The evolution of hydraulic fracturing is a long and circuitous one that deserves examination. Engineering and completions leaders from Liberty Oilfield Services did just that, authoring a paper that encapsulates the high points in the development of the groundbreaking completions practice.
-
As the country pushes for higher output from its emerging unconventional sector, nature is pushing back. To get better results, operators there are increasing their reliance on technology.
