numerical study on casing integrity during hydraulic fracturing shale formation
(2019)
Due to complex sedimentation environment, shale formations are usually characterized as highly heterogeneous and anisotropic in in-situ stresses. The injection process for reservoir stimulation changes the local in-situ ...
Stochastic Determination of Formation Parting Pressure for Water Injection Well
(2017-12)
Water injection is arguably the most widely used technology in maintaining reservoir pressure and enhanced oil recovery. However, the water injectivity always declines as water injection process continuing due to 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 ...
Stable nitrogen isotope signal in crude oils throughout geologic time
(2017-05-12)
Stable nitrogen isotopic compositions of asphaltene and NSO hydrocarbon fractions from sixty-two crude oils derived from siliciclastic, carbonate/marl, hypersaline and lacustrine source rocks of known geologic age ranging ...
Inferring Interwell Connectivity by Statistical Diagnostic Tools and Signal Processing Methods
(2018-12-14)
Data mining has become increasingly crucial in deciphering reservoir dynamics. Operators currently acquire an enormous amount of data that are not effectively being used. These data contain valuable information about ...
PERFORMACE OF UREA-BASED IN-SITU CO2 EOR: INFLUENCES OF DIFFERENT POROUS MEDIA
(2018-12-14)
Carbon dioxide (CO2) flooding has been proved as a successful method for enhanced oil recovery (EOR) in oil fields globally in recent decades. However, significant growth of applying CO2-EOR technology is largely restricted ...
Non-Destructive Index Testing For Relative Assessment Of Rock Strength
(2016)
Index tests for the determination of rock properties have been employed since the early 90s, based on methods developed since the 1900s in the metallurgical industry. Examples include the Brinell hardness test, Rockwell ...
UNCERTAINTY ANALYSIS OF PRODUCTION FORECAST IN SHALE SYSTEMS
(2019-05-10)
This research evaluates the impact of decision making and uncertainty associated with production forecast in shale oil and gas wells; over 11000 wells completed in the Barnett & Haynesville plays and more than 2000 wells ...
Numerical simulation of transient cuttings transport with foam in horizontal wells
(2013)
The use of foam for underbalanced drilling applications is increasing significantly. This is because foam exhibits properties, which are desirable when drilling depleted and low-pressure wells. However, a good knowledge ...
