Investigating And Modeling Tar-Mats In A Kuwaiti Carbonate Reservoir And Their Role In Understanding Oil Reserves And Recovery Economics, Abdullah Owidah Almansour

Doctoral Dissertations

"Tar-mat columns exist in many carbonate reservoirs in the Middle East. Historically, tar-mats have been thought to impede primary oil extraction, thus necessitating further improved oil recovery (IOR) technology applications. However, this research considers tar-mats as potential sources for unlocking extremely difficult crude oil, less than 5 ⁰API. The main objective of the study was to understand the qualitative physical and chemical properties of extremely viscous tar-mat oil and the quantitative potential of tar-mats to extract difficult oil.

The physical and chemical geneses of the tar-mat oil were analyzed utilizing several experimental geochemical techniques, including rock evaluation pyrolysis, liquid extracts …

Semantic Model And Updated Screening Criteria For Polymer Flooding, Laila Dao Saleh

Doctoral Dissertations

"Enhanced oil recovery (EOR) processes produce oil that conventional methods leave behind, where interfacial forces, heavy oil viscosity, and reservoir heterogeneity make it difficult to produce. Many EOR methods are available but usually cannot be used at the same time for a candidate reservoir. Therefore, it is important to select the most appropriate EOR process from among the possible techniques. EOR screening criteria have been created using EOR datasets and serve as the first step to compare the suitability of each technique for a specific reservoir. Most of these datasets are based on field data collected from EOR surveys published …
