Applying machine learning models to diagnose failures in electrical submersible pumps
(2022-12-17)
Electrical Submersible Pump (ESP) failures are unanticipated but common occurrences in oil and gas wells. It is necessary to detect the onset of failures early and prevent excessive downtime. This study proposes a novel ...
Stability of the working highwall in a strip mining operation and comparison of the failure in a physical model with that of a two-dimensional finite element analysis /
(1983)
This study is comprised of an analysis of slope stability in strip mines using a finite element model as well as a physical model. The physical model was designed to simulate typical rather than specific strip mine conditions ...
CHARACTERIZATION OF SURFACTANTS AND TRACER PROPERTIES FOR POTENTIAL EOR APPLICATIONS
(2017)
There are some challenges in chemical flooding, such as, gas finger problem usually occurred in field tests, potential scale problems of chemical slug caused by precipitation due to incompatibility between chemical solution ...
Leak-off and cleanup behavior of fracturing fluids in the presence of mobile hydrocarbons.
(1997)
Leak-off characteristics in the presence of mobile gas or oil saturation are significantly different compared to those observed in the presence of 100% brine saturation. In the case of mobile gas saturation, the spurt loss ...
EVALUATION OF LINER HANGER SEAL ASSEMBLY AND CEMENT SHEATH AS A DUAL BARRIER SYSTEM: IMPLICATIONS FOR INDUSTRY AND REGULATORS
(2020-05-08)
Robust dual barrier systems are crucial for well integrity. Regulators and industry have consistently raised the concerns in such systems regarding the testing, qualification, and prediction of leakage pathways and failure ...
TOWARDS A BETTER UNDERSTANDING OF THE RELATIONSHIP BETWEEN MOLECULAR FORCE AND HYDROCARBON RECOVERY
(2019-08-01)
The optimization of hydrocarbon recovery is the core of petroleum engineering. Experiments are always the go-to approach to reveal mysterious observations and verify new theories. However, recent advances on our understanding ...
NEW AND IMPROVED TECHNIQUES FOR CHARACTERIZING BRITTLE ROCK RESPONSE
(2017-12)
To improve the production from shale, stimulation technique such as hydraulic fracturing with proppants is essential. To maximize the effectiveness of hydraulic fracturing, brittle intervals with the minimum creep deformation ...
Dual-Porosity and Dual-Permeability Poromechanics Solutions for Problems in Laboratory and Field Applications
(2010)
In this work, a study of anisotropic dual-porosity and dual-permeability poromechanics is presented through generalized analytical solutions for selected problems in laboratory and field applications. For example, the ...
INVESTIGATION OF OILWELL CEMENT MIXING: EXPERIMENTAL STUDIES AND IMPLICATIONS FOR MIXING ENERGY THEORY
(2018-05-11)
Cement is a key element of wellbore integrity. Mixing condition for cement and how its properties are affected is of great importance but often ignored in the oilwell cement design. Typical cement slurry properties such ...
Numerical Simulations of Fracture Propagation Applied to Petroleum and Geothermal Reservoir Using Finite Element Method
(2015-08)
Hydraulic fracturing is a major technique in reservoir stimulation to enhance production. Better understanding of mechanisms of hydraulic fracturing is essential for designing hydraulic fracture treatments. Multiple physical ...
