Enhanced recovery
This paper provides an account of the design, implementation, and operational insights from an enhanced geothermal system proppant stimulation targeting a volcanic, dry rock setting with an approximately 330°C bottomhole temperature.
This paper describes modeling work performed to design fracturing treatment and spacing for wells in the Project Cape enhanced geothermal system in Utah.
This paper reviews the simultaneous supercritical CO2/brine aquifer injection and water-alternating-gas methods for geologic carbon sequestration and proposes a novel integration with saltwater-disposal wells.
-
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.
-
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.
-
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.
-
The authors of this paper describe reservoir-fluid-geodynamics processes that explain the reasons behind varying oil compositions and properties within and across different reservoir compartments.
