Enhanced recovery
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.
This work investigates the root cause of strong oil/water emulsion and if sludge formation is occurring within the reservoir using a robust integrated approach.

The authors describe the applicability of 110,000-psi yield-strength quench-and-tempered coiled tubing strings in high-pressure sour environments through implementation of a custom-fit coiled tubing integrity and risk-mitigation program. -
In this paper, the authors discuss what components have contributed to recent proppant-placement cost reductions and use several case studies to illustrate the potential for further cost reductions.

This paper summarizes the performance of a polymerflooding pilot conducted in an unconsolidated sandstone reservoir in Oman.
-
This paper aims to clarify misconceptions regarding polymerflooding implementation based on theory and practice in China.
-
It is pleasantly surprising to find a revival in sandstone acidizing. For many years, sandstone acidizing was becoming almost a lost art, overshadowed by carbonate acidizing and hydraulic fracturing.
-
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.
