Enhanced recovery
Coreflood experiments reveal that alkali significantly reduces viscosity loss in polyacrylamide flooding systems by minimizing adsorption and improving polymer stability under shear stress. The findings position viscosity retention as a key screening criterion for successful alkali-polymer enhanced-oil-recovery applications.
This study investigates the potential for in-situ hydrogen generation from hydrocarbons using in-situ combustion, with particular emphasis on the role of kerogen content and heating mode.
This paper presents the application of degradable particulate-diverter technology to improve oil production by effectively diverting stimulation treatment fluids away from high-water-cut, high-permeability, high-temperature producing intervals or zones.

This paper illustrates a novel methodology that enabled the safe application of coiled tubing abrasive perforation to increase production in a sour horizontal extended-reach oil producer. -
This paper presents a new real-time method to estimate stage-to-stage interference and well-to-well interference and their implications on completions efficiency.
-
As the announcement of carbon sequestration projects becomes the norm, it’s time we look at what we know from a technical angle about how these projects need to be run based on the industry’s experience with enhanced oil recovery.

This paper summarizes the integrated technical learnings from the successful application of the installation of autonomous outflow control technology in a new long horizontal injector well.
-
This paper describes how a better understanding of the connection between the well and the reservoir through use of fiber-optic sensors can improve reservoir simulation models, decision-making, and well-performance evaluation.
-
In this study, the application of electrical resistance heating on multilateral wells is studied to illustrate the enhanced physical and economic benefits of the method.
-
This paper introduces methods to fully couple reservoir simulation with wellbore flow models in fractured injection wells.
-
The paper presents a model for shale gas production in which CO2 is injected by huff ’n’ puff into a hydraulic fracture surrounded by a shale matrix.
-
Statistics are important in knowing where the sharp minds of SPE members are investing their energies. Typically, this is also in proportion to what those members need. Hence, it is noteworthy that more than a fifth of the papers were about CO2-based EOR, indicating not only renewed interest but also the motivation for carbon capture, use, and storage.
