Acoustic Velocity Study in Tight Anhydritic Dolomite of the Late Permian Khuff Formation
Almuzel, Mohammed (2016-12-16)Carbonate reservoirs are usually associated with diagenesis processes which result in complex mineralogy and pore structure. As a result, rock physics models that predict the petrophsyical properties using seismic based ... -
CALCULATION OF ESTIMATED OIL RECOVERY USING CARTER TYPE CURVES
Goodluck, Nosirat (2017-05-12)The focus of this research is to calculate the Estimated Ultimate Recovery (EUR) of shale wells for a diverse range of fluid types using Carter (1985) type curves. The Carter (1985) type curve is a plot of flow rate versus ... -
Case studies in causal inference and anomaly detection
Sakhardande, Rohan Rajan (2020-12-18)The study of parent-child well interactions in unconventional shales has generated high interest both in the industry and academia over the last decade. This is largely because of the growing number of child wells and their ... -
Data Mining Applications in Reservoir Modeling
Dong, Xiaomeng (2016-08-08)Data science has gained great attentions in many fields over the last decade, in this thesis, I further explored the use of data science technique in oil industry and developed three data mining applications that could be ... -
DATA-DRIVEN REAL-TIME GEOSTEERING USING SURFACE DRILLING DATA
Holasek, Connor (2019-12-13)In this thesis I present a method for estimating lithology or deriving formation properties from real-time surface drilling data. This information can then be used to enhance real-time geosteering capabilities. Current ... -
DEEP LEARNING FOR SHALE SEM IMAGE ANALYSIS
Knaup, Amanda (2020)The microstructure of unconventional reservoir rocks not only controls the storage and transport of hydrocarbons but also controls the mechanical properties of the shale. Scanning Electron Microscopy (SEM) has been valuable ... -
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. ... -
EXPERIMENTAL INVESTIGATION OF PROPPED FRACTURE CONDUCTIVITY
Mittal, Abhinav (2018-05)Hydraulic fractures act as conduits connecting a wellbore to nanodarcy permeability unconventional reservoirs. Proppants are responsible for enhancing the fracture conductivity and help in maintaining high production rates. ... -
Experimental Investigation of Synthetic and Microbial Surfactants for Enhanced Oil Recovery in Bone Spring Sandstones
Pandey, Rishabh (2022-12-17)Surfactants have been used to increase hydrocarbon recovery to meet the increasing demand for oil and gas. This mechanism of using surfactants reduces the Interfacial Tension (IFT) at the fluid/fluid interface and wettability ... -
EXPERIMENTAL STUDY OF EFFECT OF PROPPANT CONCENTRATION, TYPES, SIZES, ROCK MINERALOGY AND OVERBURDEN STRESS ON FRACTURE CONDUCTIVITY
Gupta, Abhishek Kumar (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
Min, Byeungju (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, ... -
Experimental Study of Proppant Pack Deformation
Taneja, Shantanu (2016)Unconventional reservoirs, especially shales are drilled horizontally and hydraulically fractured for economical production. Proppant is carried and placed with the use of fracturing fluid to maintain fracture conductivity ... -
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 ... -
INVESTIGATING MICROSTRUCTURAL HETEROGENEITY IN ORGANIC SHALE VIA LARGE-SCALE, HIGH RESOLUTION SEM IMAGING
Tran, Hung (2017)The physical properties of shale are fundamentally controlled by its microstructure; however, shale is problematic due to microstructural heterogeneity that can exist across multiple scales. This creates difficulty in ... -
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. ... -
Measurement and analysis of oil-gas diffusion at reservoir conditions: application to huff-n-puff EOR in unconventional reservoirs
Mukherjee, Sanchay (2020)Due to the extremely low permeability and high depletion rate, primary recovery from unconventional reservoirs is generally low. Huff-n-Puff has proved to be a successful EOR technique in tight formations, such as the Eagle ... -
Meramec velocity systematics
Fu, Jing (2020-07-30)Elastic wave velocities are often used to interpret formation properties, such as porosity, mineralogy, and lithology. Shear wave velocity systematics are valuable in creating elastic models when only P-wave sonics exists ... -
