Characterization of Surface Energies of Hydrocarbon Formation Rocks for Enhanced Hydrocarbon Recovery

Quoc P. Nguyen, Gary A. Pope

Funding source: Saudi Aramco

Funding amount: $250,000 per year

The physical and chemical interactions between crudes, brines, and rock determine both oil reserves and producibility. Measurements of these interactions are difficult and research in the past has mainly concentrated on sandstone reservoirs. In particular, limestones and dolomites are poorly investigated.

Flow Transport Modeling

Gary A. Pope, Mojdeh Delshad

The objective of this research is to develop and apply a three-dimensional, multiphase, multicomponent model capable of simulating the fate and transport of nonaqueous liquids (NAPLS) in the saturated and unsaturated zones of confined and unconfined aquifers. The model is capable of simulating multiple solids and fluid phases under realistic aquifer conditions and transformation of both organic and microbiological species. Some of the specific objectives of this research are:
 

Mechanisms for Permanent CO2 Trapping in Sedimentary Rocks

Steven L. Bryant, Gary A. Pope

Funding source: Advanced Technology Program (State of Texas)

Funding amount: $150,000 for the period of January 2004 - December 2006

Geological sequestration is one way greenhouse gases can be mitigated in sufficient volumes. This project focuses on obtaining quantitative assessments of the potential for permanent geological sequestration of carbon dioxide in aquifers.

Modeling Wettability Alteration Using Chemical Enhanced Oil Recovery Processes in Naturally Fractured Reservoirs

Mojdeh Delshad, Kamy Sepehrnoori, Gary A. Pope

Funding amount: $445,000 for the period of Oct. 2004 - Sep. 2007

This research will provide a computer model of the complex wettability alterations that occur when detergents are used to induce oil production from fractured oil reservoirs. Extremely large volumes of oil remain in such known oil reservoirs and better models are needed to economically produce such oil by enhanced oil recovery methods.

Surfactant Enhanced Aquifer Remediation

Abstract

The presence of dissolved-phase plumes of chlorinated solvents in many US aquifers was documented by the Council on Environmental Quality in 1981. Mackay and Cherry summarized the evidence that these plumes were derived from the dissolution and volatilization of chlorinated solvents and other dense, non-aqueous phase liquids (DNAPLs) present, but not necessarily observed, in sediment and rock beneath spill sites.
