RHEOLOGY OF AQUEOUS AND POLYMER-BASED NITROGEN FOAMS AT HIGH PRESSURE AND HIGH TEMPERATURE (HPHT) CONDITIONS
(2017-05-12)
Foams are complex mixtures of gas and liquid held together by a surfactant at the gas-water interface. The use of foams find application in many industrial operations such as underbalanced drilling fluid, fracturing fluid ...
MECHANISTIC MODEL OF COMPLEX CONDUCTIVITY OF POROUS MEDIA CONTAINING CONDUCTIVE PARTICLES OF VARYING WETTABILITY
(2019-08)
Electrically conductive particles, such as graphite and pyrite particles, and surface-charge-bearing nonconductive particles, such as sand and clay grains, are commonly present in subsurface geological formations. When a ...
Petrophysical rock typing in Uinta Basin using models powered by machine learning algorithms
(2023)
Petrophysical characterization is key to identifying different rock types for hydrocarbon production optimization. Rock-typing, a petrophysical characterization technique, can be performed using wireline measurements, such ...
Effects of Pressure and Oil Contamination on Drainage and Bubble Size Distribution of Aqueous Foams
(2022-05-14)
Foams exhibit valuable properties such as high viscosity, low density, and good cutting carrying capacity. However, they are thermodynamically unstable due to gravitational drainage, bubble coalescence, and coarsening. As ...
EXPERIMENTAL STUDY OF EFFECT OF PROPPANT CONCENTRATION, TYPES, SIZES, ROCK MINERALOGY AND OVERBURDEN STRESS ON FRACTURE CONDUCTIVITY
(2019-12-13)
Hydrocarbon production from unconventional reservoirs, particularly shales, requires massive hydraulic fractures to expose the large surface areas within the formation and provide a conduit to the wellbore. Proppants are ...
INTERRELATING PRODUCTION ANALYSIS WITH PORE SCALE STRUCTURE IN THE BAKKEN RESERVOIR
(2016)
Improving well performance and associated project economics in oil resource plays rely on developing reservoir characterization capabilities. The need for understanding pore-scale geometry in low porosity low permeability ...
Case Study: Integrated Core Modeling and Simulation of Unconventional Hydraulically Fractured Wells in the Delaware Basin
(2020-07-30)
The Early Paleozoic Wolfcamp formation is one of the main unconventional reservoirs in the Delaware Basin, and highly targeted by U.S. companies. Innovative completion techniques and representative core analysis have ...
FRACTURING OPTIMIZATION BASED ON DYNAMIC CONDUCTIVITY
(2016)
This thesis presents a systematic approach to evaluate and optimize production performance of fractured wells in tight oil formations. Underperformed hydraulically fractured wells have been widely reported; poor design is ...
Integrated Production Data Analysis of Horizontal Fractured Well in Unconventional Reservoir
(2016-12-16)
This thesis presents a novel analytical solution to predict the expansion of drainage volume for compound transient linear flow system consisting of stimulated-reservoir volume (SRV) and unstimulated shale/tight sandstone ...
Preparation of Field Validation for an All-Digital, Permanent Downhole Pressure Sensor Design
(2023-12-15)
Downhole pressure sensing has become increasingly important in oil and gas operations. Some of the many advancements provided by an improvement in downhole sensing is seen in drilling, stimulation, production forecasting, ...
