carbonates

The First Eocene is a multibillion-barrel heavy-oil carbonate reservoir in the Wafra field, located in the Partitioned Zone between Saudi Arabia and Kuwait. After more than 60 years of primary production, expected recovery is low and provides a good target for enhanced-oil-recovery processes.

This paper provides a robust methodology for miscible CO2 WAG experimental-data acquisition and history matching.

To the best of the authors’ knowledge, this is the first surface-complexation-based model that describes fully ionic compositional dependence observed in ionically treated waterfloods in both sandstones and carbonates.

This paper proposes a new method of economic prediction on the basis of expert library and oilfield databases. The method takes into account geological factors and the effect of production factors on the economic prediction.

The objective of this paper is to illustrate a methodology for identifying the value of information (VOI) in reservoir management—in particular, for deriving the conditional probabilities of success when new and imperfect data are acquired.

A pilot project demonstrates that facilities design plays an important role in providing sources of CO2 for the gas-handling process for injection into a carbonate formation as a tertiary recovery mechanism.

Natural fractures can have a significant effect on fluid flow by creating permeability anisotropy in hydrocarbon reservoirs.

The evolution of horizontal drilling and multistage completions has changed matrix stimulation from the “more acid, better result” belief to effective lateral distribution and deeper penetration with less acid.

Despite an abundance of discovered resources, most companies are still running at unsustainable reserves replacement levels, necessitating further investment in exploration of conventional and unconventional reservoirs.

This paper discusses a crestal gas-injection project that was carried out in a supergiant heterogeneous-carbonate oil field.
