APPLICATIONS OF MACHINE LEARNING METHODS IN THE GENERATION OF SUBSURFACE MEASUREMENTS
He, Jiabo (2018-05-11)Machine learning methods have been used in the Oil and Gas industry for about thirty years. Applications range from interpretations of geophysical, well and seismic responses, identification of minerals, analysis of rock ... -
CONNECTIVITIES OF VARIOUS COMPONENTS IN ORGANIC-RICH SHALE
Wu, Yaokun (2019)The physical properties of shale are fundamentally controlled by its microstructure. Connectivity of various components in shale is an important property that governs the transport of mass, energy and momentum. Quantifying ... -
Estimation of Relative Permeability in Nanoporous Samples and Modeling of Pressure Transient Response in Naturally Fractured Reservoirs
Ojha, Shiv Prakash (2017-12-15)Relative permeability and irreducible saturations of organic-rich shale samples from various formations from different maturity windows are estimated by processing the low-pressure nitrogen adsorption-desorption measurements. ... -
Forecasting Ultimate Recovery Using Probablistic Model for Flow-Regime Changes
Childers, David (2016-08-19)Determination of the yet to be produced oil and gas prescribes the assets of a company. This is important internally in regard to budgeting and externally in regard to the valuation of the company. The yet to be produced ... -
Integrated Production Data Analysis of Horizontal Fractured Well in Unconventional Reservoir
Zheng, Da (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 ... -
INTERPRETATION OF GALVANIC RESISTIVITY, ELECTROMAGNETIC INDUCTION, AND DIELECTRIC DISPERSION LOGS TO ESTIMATE WATER SATURATION IN ORGANIC RICH SHALE
Tathed, Pratiksha (2018-12)Water saturation estimation based on electrical and electromagnetic logs in organic-rich shale reservoirs is challenging due to effects of clay and conductive minerals. Presence of nanopores, low porosity, interfacial ... -
A LOW-FREQUENCY ASYMPTOTIC FORMULATION TO ESTIMATE HYDRAULIC FRACTURE PROPERTIES FROM PRESSURE DATA
Al-Sammarraie, Rafeef (2016-12-16)The key drivers of success in unconventional oil and gas recovery, specifically in shale plays, is the rapid growth in hydraulic fracturing and horizontal well technology. With these completion methods, wells contact ... -
Machine learning for the subsurface characterization at core, well, and reservoir scales
Li, Hao (2020-05-08)The development of machine learning techniques and the digitization of the subsurface geophysical/petrophysical measurements provides a new opportunity for the industries focusing on exploration and extraction of subsurface ... -
MAPPING HYDRAULIC FRACTURE USING SHEAR WAVE
Bhoumick, Pritesh (2018-12)It has become critical to understand the location of hydraulic fracture and the extent to which it stimulates a reservoir to plan future drilling and completions. Various methods have been used to map the fracture propagation. ... -
MECHANISTIC MODEL OF COMPLEX CONDUCTIVITY OF POROUS MEDIA CONTAINING CONDUCTIVE PARTICLES OF VARYING WETTABILITY
Jin, Yuteng (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 ... -
Modeling Multicomponent Gas Flow in Liquids Rich Shales
Kim, Jihyuk (2016-05)Production data acquired from liquids-rich shale reservoirs show a few very interesting trends: 1. A relatively constant gas-oil ratio (GOR) or condensate-gas ratio (CGR) although flowing bottomhole pressures may be below ... -
Modeling of non-equilibrium effects in particulate flow through porous media
Jin, Yi (2018)The complex dynamics of fluid and particles flowing through pore space demands some relaxation time for particles to catch up with fluid velocity which manifest themselves as non-equilibrium (NE) effect. Previous studies ... -
NUMERICAL SIMULATION OF THE EFFECTS OF RESERVOIR HETEROGENEITY, FRACTURES, AND MULTI-WELL INTERFERENCE ON PRESSURE TRANSIENT RESPONSES USING MULTISTENCILS FAST MARCHING METHOD
Yoon, Sangcheol (2017-08-28)Analysis of rate and pressure transient responses of a well in spatially heterogeneous reservoir cannot be performed using conventional well-test analytical equations. An accurate analysis of transient pressure/rate responses ... -
