carbonates

The authors of this paper describe an underbalanced coiled-tubing drilling campaign in the operator’s onshore fields using a closed-loop system design.

This paper presents the interpretation of two polymer-injectivity tests performed in two giant light-oil high-salinity/high-temperature carbonate reservoirs onshore Abu Dhabi.

The first acid job dates to 1895. Challenges remain, however, when it comes to lithology, coverage, penetration, and management of reaction products. These themes remain a focus for stimulation engineers.

The authors of this paper show the migration of a CO2 plume within a depleted carbonate reservoir and the expected effects of CO2 saturation and pressure buildups during injection on time lapse 4D seismic for conformance monitoring.

This work explores the synergistic effects of smartwater in polymerflooding, surfactant/polymerflooding, carbonated waterflooding, and foam-assisted gas-injection.

In this study, surfactants that can alter wettability or develop ultralow interfacial tension were identified through laboratory measurements for a target carbonate reservoir.

This paper describes the deployment of an ultradeep electromagnetic directional-resistivity instrument to map injection-water movement.

The authors of this paper describe a project that integrates carbonate stratigraphic forward models of outcropping formations and reservoir-modeling work flows.

To improve the productivity index of a well in a carbonate reservoir offshore Abu Dhabi, a multilateral acid-jetting technology was adopted as a more-effective alternative to typical drainage methods.

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.
