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 ...
EXPERIMENTAL STUDY OF GAS INJECTION ENHANCED OIL RECOVERY IN SHALE RESERVOIRS
(2019)
Miscible gas injection enhanced oil recovery (huff-n-puff gas injection) has received increased
attention especially in the unconventional plays like the Eagle Ford, where oil recovery is as low
as 5 – 10% (Sheng, ...
SULFIDE STRESS CRACKING BEHAVIOR OF GRADE C-110, Q-125 AND T-95 STEEL TUBULARS UNDER HIGH-PRESSURE CONDITIONS
(2016-12-16)
Due to the expansion of hydrocarbon exploration into challenging sour oil and gas resources, the industry is now facing severe sour related corrosion problem. Sulfide Stress Cracking (SSC) is one of the detrimental types ...
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 ...
CFD Analysis of Power-Law Fluid in a Partially Blocked Eccentric Annulus Under Turbulent Flow Conditions
(2019-12)
An increase in hydrocarbon production by the application of several laterals from a single vertical wellbore is now a widespread practice. Horizontal and inclined wells are drilled at record lengths, which once seemed ...
EXPERIMENTAL STUDY OF THE RHEOLOGY AND STABILITY BEHAVIOUR OF SURFACTANT STABILIZED WATER-IN-OIL EMULSION
(2016-12-16)
Formation water almost always comes out with crude oil production. Under extreme mixing and high turbulence provided by pumps, valves, chokes and pipelines in the production system, water and oil can mix to form highly ...
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 ...
Revisiting the mechanisms of clay damage
(2016-05)
Molecular dynamics simulations were used to investigate the underlying mechanisms of water interaction with Wyoming-type montmorillonites. The study focused on (1) the clay swelling process for different cations with the ...
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 ...
Application of a New Yield Strength Acquisition Method to the Calculation of Collapse Pressure
(2018)
The accuracy of a casing collapse prediction is critical to a successful casing design program. This is especially true today as the likelihood of HPHT reservoirs and difficult conditions downhole has become increasingly ...
