Enhanced recovery
In a study that applied alternative carbon carrier technology to enhanced oil recovery (EOR) scenarios, researchers at The University of Texas at Austin found that the new method recovered up to 19.5% more oil and stored up to 17.5% more carbon than conventional EOR methods.
This paper reviews lean construction management processes adopted in the Apani Field development, from facility design to construction management and drilling-location preparation.
This paper presents a novel workflow with multiobjective optimization techniques to assess the integration of pressure-management methodologies for permanent geological carbon dioxide storage in saline aquifers.

The authors of this paper describe a method of stimulating a multizone hydrocarbon-producing well wherein a tool is deployed downhole by wireline to generate acid vapor at a target depth, allowing each interval to be treated uniquely. -
This paper discusses the effect of injected-polymer viscosity on various aspects of a project, from recovery to surface facilities, including both theoretical arguments and practical field experience—which do not always align.
-
This study leverages oil-fingerprinting technology and geochemical data to evaluate the fluid connectivity between a main field and its stepout wells.
-
This paper provides details of a pilot study conducted on multiple wells, showcasing the potential of a novel biotechnology in Bakken enhanced oil recovery.
-
In this work, microseismic observations are integrated with strain and other observations to investigate the microseismic response in relation to the underlying hydraulic fracture geometry for different rock types.

This year’s Acidizing feature presents three SPE conference papers that discuss an important battlefront of enhanced production—carbonate reservoirs, those plays whose heterogeneity, reactivity, and flow behavior pose challenges that remain comparatively little-understood, despite the industry’s intensified efforts to maximize their output.
-
The three papers selected for this feature highlight some creative solutions that aim to increase project value by either increasing recovery or optimizing injectant cost, or both.
-
This paper extends an integrated two-scale continuum model that contemplates mass, momentum, and energy changes to study the acid-stimulation process in complex carbonate acid-stimulation systems with the development of fracture and vug networks.
-
The authors of this paper write that autonomous outflow-control devices can positively affect matrix acidizing by providing the best possible conformance.
-
This study combines preshear degradation, permeability, and oil presence effects to evaluate and improve polymer injectivity using acrylamido tertiary butyl sulfonate (ATBS) polymer in carbonate rock.
