Laboratory Evaluation of Static and Dynamic Sag in Oil-Based Drilling Fluids
(Journal article; Peer reviewed, 2020)In this paper, we present the results of barite sag measurements before and after hot-rolled oil-based drilling fluids (OBDFs) using different approaches for characterization. We characterized the barite sag of a liquid ... -
Nanosized Magnesium Oxide With Engineered Expansive Property for Enhanced Cement-System Performance
(Journal article, 2017)The bulk shrinkage of cement sheaths in oil wells can result in loss of long-term zonal isolation. Expansive additives are used to mitigate bulk shrinkage. To compensate effectively for bulk shrinkage during the late plastic ... -
Significance of Geochemistry in Single-Well Chemical-Tracer Tests by Coupling a Multiphase-Flow Simulator to the Geochemical Package
(Journal article; Peer reviewed, 2018)Single-well chemical tracer (SWCT) is the most commonly used field method to determine oil or water saturation in one-well enhanced-oil-recovery (EOR) pilots. Because hydrolysis of an ester, which is the main part of the ... -
Strategies for Petroleum Exploration on the Basis of Bayesian Networks: A Case Study
(Journal article; Peer reviewed, 2014)The paper presents a new approach for modeling important geologicalelements, such as reservoir, trap, and source, in a unified statistical model.This joint modeling of these geological variables is useful for reliableprospect ... -
Surface-Charge Alteration at the Carbonate/Brine Interface During Single-Well Chemical-Tracer Tests: Surface-Complexation Model
(Journal article; Peer reviewed, 2018)Water chemistry has been shown to affect oil recovery by affecting surface charge and rock dissolution. The single-well chemical-tracer (SWCT) test is a field method to measure residual oil saturation (Sor), in which ...
