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 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.
This paper reviews lean construction management processes adopted in the Apani Field development, from facility design to construction management and drilling-location preparation.

For nearly a decade, Saudi Aramco has been studying how altering the chemical makeup of seawater injected into its reservoirs can increase production. The result is "smart water" that can boost the sweep effectiveness of a waterflood. -
With the easy conventional oil in Argentina having been produced, one remaining way to find new oil in existing fields is to convert fields from primary or secondary production to secondary or tertiary production, respectively.

Carbon dioxide (CO2)/water foams are of interest for mobility control in CO2 enhanced oil recovery (EOR) and as energized fracture fluids or as hybrid processes that combine aspects of both processes.

There remain a number of challenges with CO2 EOR. These include gravity override, poor sweep efficiency, and economic factors.

In this study, detailed petrophysical and geological field models focusing on the middle and lower members of the Bakken Formation were developed.

This paper describes a gas-injection pilot that has been implemented in offshore Middle East carbonate reservoirs to assess injectivity, productivity, macroscopic-sweep efficiency, flow assurance, and operational efficiency in a field that has a long water-injection history.

The operator has initiated a cyclic-steam-stimulation project in the Opal A diatomite of the Sisquoc formation on the Careaga lease in the Orcutt oil field in Santa Barbara County, California. This paper discusses steam-injection step-rate tests (SRTs) for this asset as part of its expansion.

The polymer-injection project in the Dalia field, one of the main fields of Block 17 in deepwater Angola, represents a world first for both surface and subsurface aspects.

The Loma Alta Sur (LAS) field is a multilayer fluvial sandstone reservoir in the Neuquén basin of Argentina. Colloidal-dispersion-gel injection was considered a viable strategy to improve oil recovery in the field after early water breakthrough.

Since 2006, production from gas injection has outstripped that from thermal, and is continuing to grow. Even though industry conditions remain tough, EOR is expected to be increasingly important in the future, with the possibility of further uptake of it linked to the climate-change agenda.
