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 ...
A DISLOCATION-BASED BOUNDARY ELEMENT METHOD TO MODEL PRESSURIZED FRACTURES
(2019)
A significant portion of hydrocarbon and geothermal resources in the world, and especially in the United States, is unconventional. Some of the unconventional resources have special geological structures so that their ...
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 ...
INVESTIGATION OF THE EFFECT OF TEMPERATURE ON LOW-SALINITY WATERFLOODING
(2019-08-01)
Even though Low-Salinity Waterflooding (LSW) has been under investigation as a promising Enhanced Oil Recovery (EOR) technique for almost three decades, most of the studies in the literature are focused on investigating ...
INVESTIGATION OF DRILLSTRING VIBRATIONS USING FINITE ELEMENT METHOD SIMULATIONS AND DESIGN AND IMPLEMENTATION OF EXPERIMENTAL SETUP
(2017-05-12)
In this study, an extensive assortment of the principal studies related to drill-string vibrations is presented, focusing on analytical studies, finite element models and experimental setups. A discussion on the current ...
DETERMINATION OF SHALE ANISOTROPIC POROVISCOELASTIC PROPERTIES FROM THREE-POINT BEAM BENDING TEST
(2017-05-12)
Permeability is an extremely important property of shale. It is essential to know permeability as it can aid engineers in developing drilling and production strategies and help executives make important financial decisions. ...
