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 ...
Surface Area Study in Organic Rich Shales using Nitrogen Adsorption
(2017)
Low-pressure nitrogen adsorption technique was used to investigate the specific surface area and pore size distributions and controlling factors for 11 wells from seven different shale formations with varying thermal ...
Importance of Capillary Heterogeneity in Developing a Representative Reservoir Model for Shales with Complex Fractures
(2016-12-16)
Our advancement in hydraulic fracturing has enabled us to produce shale formations economically. The formation stimulation is successful when the effective transport properties of the formation is improved significantly, ...
A Systematic approach to determine the optimal production rate to inhibit asphaltene deposition
(2016-08)
This thesis utilizes a systematic mathematical model, scaling analysis, to quantify the effect of production rate on asphaltene deposition, using a set of uniquely described mathematical equations modeled for the deposition ...
Multistage Triaxial Test on Conventional and Unconventional Rocks
(2017-05-12)
The triaxial test is a technique commonly used to determine the failure stress of rocks in compression. Typically, a series of triaxial tests are needed to establish a failure envelope. Unfortunately, the practical constraint ...
AN EXPERIMENTAL INVESTIGATION ON CREEP BEHAVIOR OF SHALE ROCKS: WITH EMPHASIS ON THE INFLUENCE OF TEMPERATURE AND ANISOTROPY
(2017-05-12)
The deformation of materials under constant load over time is called creep. The conductivity of fracture produced by hydraulic fracturing decreased over time as a result of this time dependent phenomenon that requires to ...
ON THE FATE OF THE FRACTURING FLUID AND ITS IMPACT ON LOAD RECOVERY AND WELL PERFORMANCE
(2016-08-01)
The complexity of the shale system coupled with the mystery of low fracturing fluid recovery has puzzled many researchers. Field reports from hydraulic fracturing operations performed on shale formations have highlighted ...
EXPERIMENTAL INVESTIGATION OF THE EFFECTS OF ROTATIONAL SPEED AND WEIGHT ON BIT ON DRILLSTRING VIBRATIONS, TORQUE AND RATE OF PENETRATION
(2017-05-12)
Experimental investigation was carried out on an automated drilling rig fabricated for the Drillbotics competition. The effects of rotational speed and weight on bit were observed on drillstring vibrations, torque and rate ...
Moisture effects on dynamic elastic properties of shale from deep formations
(2018-12-14)
Geomechanics testing is an important component of reservoir geomechanics studies for improving drilling, and stimulation operations. Usually the cores for geomechanical tests are exposed to non-native fluid and air prior ...
IMPROVED SURFACTANT PERFORMANCES IN POROUS MEDIA: EFFECTS OF HYDROTROPES AND BIO-COLSOVENTS
(2018-12)
Surfactant flooding for the mobilization of residual oil is a promising technology for enhanced oil recovery (EOR) and surfactant enhanced aquifer remediation (SEAR). A significant economic barrier to the widespread use ...
