Quantification of recovery factors in downspaced shale wells
(2016-12-16)
Well spacing optimization in horizontal multi-fractured wells is the center of field development. Unconventional reservoirs due to the low matrix permeability cannot produce without the help of hydraulic fracturing. Unlike ...
EXPERIMENTAL INVESTIGATION OF PROPPED FRACTURE CONDUCTIVITY
(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. ...
Acoustic Velocity Study in Tight Anhydritic Dolomite of the Late Permian Khuff Formation
(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 ...
Viscosity of Shale Gas
(2017)
Unconventional energy resources, including coal beds, tight gas sands, and shales, have become an ever-increasing factor in the North American gas supply. In these formations, the basic transport properties of the fluids ...
Steady State Permeability Measurements in Shales
(2018)
Characterizing matrix permeability in shale formations is vital to determining the long term productivity of a reservoir as well as determining the optimal completion design. Permeability of shales lies in the nanodarcy ...
NUMERICAL SIMULATION OF THE EFFECTS OF RESERVOIR HETEROGENEITY, FRACTURES, AND MULTI-WELL INTERFERENCE ON PRESSURE TRANSIENT RESPONSES USING MULTISTENCILS FAST MARCHING METHOD
(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 ...
DENSITY CHANGES AND COMPOSITIONAL PATH DURING CO2 INJECTION
(2016-12-16)
CO2 EOR has been used for a couple of decades as it improves oil recovery. With more than 50% of original oil in place (OOIP) remaining inside reservoir after primary and secondary stage, more and more companies start to ...
A LOW-FREQUENCY ASYMPTOTIC FORMULATION TO ESTIMATE HYDRAULIC FRACTURE PROPERTIES FROM PRESSURE DATA
(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 ...
TRANSIENT TEMPERATURE BEHAVIOR IN WELLBORE AND SURROUNDING FORMATION
(2017-05-12)
Transient temperature behavior in a wellbore develops as a result of heat exchange between fluid in the wellbore and surrounding formation as the hot fluid from reservoir moves upward in production, or vice versa during ...
INVESTIGATING MICROSTRUCTURAL HETEROGENEITY IN ORGANIC SHALE VIA LARGE-SCALE, HIGH RESOLUTION SEM IMAGING
(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 ...
