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.
-
While enhancing oil production from multizone, hydraulically fractured completions in tight reservoirs is not straightforward, recent studies have shown that applications such as gas injection and waterflooding have the potential to create significant improvement in oil recovery. -
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.
-
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.
-
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.
