Pore-scale Modeling and Multi-scale Characterization of Liquid Transport in Shales
(2018-12-14)
Distinct from conventional reservoirs, shale formations have limited pore connectivity and unique pore spatial-distribution. Consequently, theoretical pore-network models developed for conventional formations are not ...
BARITE SAG UNDER DYNAMIC AND ELEVATED TEMPERATURE CONDITIONS: EXPERIMENTAL STUDIES AND MATHEMATICAL MODELING
(2019-05-10)
Barite sag is an undesired occurrence that causes density variation in the wellbore. It is a problem that is related to both fluid property (mainly rheology) and drilling practices, and it arises mostly in invert emulsion ...
MODELING RELAXATION EFFECTS ON MULTIPHASE FLUID TRANSPORT IN WELLS AND PIPELINES
(2012)
The effect of relaxation in processes involving phase transition during flow of reservoir fluids in pipelines and wells is investigated and formulated. Applications concerning the steady-state flow of producing wells, ...
Rheological and Flow Characteristics of Drag Reducing Surfactant Solutions in Straight Pipes and Annular Ducts
(2014)
Surfactants are well-known as effective drag reducers and viscosifying agents. The macroscopic properties of surfactants are dictated by the surfactant type and the condition of the solvent in which the surfactant is ...
QUANTIFYING PARTICLE TRANSPORTATION FOR UNCONVENTIONAL RESERVOIR CHARACTERIZATION
(2017-12)
The objectives of this research dissertation include: (1) develop a novel procedure of single well chemical tracer test (SWCTT) and modification of method of moments (MoM) to estimate mobile oil saturation; (2) apply ...
Data Assimilation Using The Ensemble Kalman Filter With Emphasis On The Inequality Constraints
(2010)
The reliability of reservoir models generally increases as more data are included during their construction. In the recent past, the ensemble Kalman lter (EnKF) technique has established itself as a viable data assimilation ...
UNDERSTANDING THE FUNDAMENTAL DRIVE MECHANISMS FOR HUFF-N-PUFF ENHANCED OIL RECOVERY IN TIGHT FORMATIONS
(2019-12-13)
Unconventional oil and gas resources have recently become the major source of produced hydrocarbons in the US. The change in the energy landscape follows nearly two decades of technological breakthroughs including horizontal ...
PREDICTIONS OF CRITICAL GAS RATES IN HORIZONTAL AND DEVIATED WELLS
(2015-05)
The author’s intent through this work is to shed light on the current methods of predicting the onsets of liquid loading and to clarify that there is a difference in critical gas rate predictions between horizontal and ...
STUDY AND DEVELOPMENT OF IN-SITU CO2 ENHANCED OIL RECOVERY
(2018-05-11)
While the injection of CO2 has great potential for increasing oil production, this potential is limited by site conditions and operational constraints such as the lack of proper infrastructure, limited cheap CO2 sources, ...
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 ...
