INVESTIGATION OF PLUGGING IN ORIFICE, SLOT, AND PORE-THROAT BY FINE PARTICLES
(2010)
orifice- or slot-to-particle-size ratio on flowing fluid conditions and plugging time that lead to particle bridging. It was demonstrated that the critical orifice- or slot-to-particle-size ratio vs. particle-volume-fraction ...
Modeling interporosity flow for improved simulation of naturally fractured reservoirs.
(2002)
Results from the numerical examples presented in this study indicate that the physical phenomena considered in the present model would predict shorter water breakthrough times and less oil recovery from the matrix, compared ...
Multi-criteria optimization model for thermal recovery processes.
(1983)
In the Loco field case study, the steam drive enhances the heavy oil recovery by decreasing the oil viscosity and increasing the injectivity; therefore, a quicker return of investment is predicted. However, the in-situ ...
PORE-NETWORK MODELING AND ANALYSIS OF LABORATORY INDUCED HYDRAULIC FRACTURES
(2018-05)
Well stimulation is undertaken to reduce the restriction to flow in a reservoir. Among all the well stimulation techniques, hydraulic fracturing is one of the most widely employed techniques due to the development of shale ...
Study towards improving the efficiency of matrix acidizing in oil-bearing carbonate formations
(2021-08)
Matrix acidizing in carbonate formations is a common technique to improve well productivity. Since more than 60% of the world’s reservoir formations are carbonates, enhancing the process of acidizing can have a significant ...
Three-dimensional fully coupled geomechanical modeling of the response of Oklahoma faults to saltwater disposal
(2021-08-05)
In the last decade, parts of the Central United States experienced marked increase in the number of small to moderate-sized earthquakes. Among all states, Oklahoma has experi-enced the most increase in the number of ...
The accuracy of pulsed neutron capture logs for residual oil saturation determinations.
(1981)
Pulsed neutron capture logs have been used to determine residual oil saturations for many years. A previous study found that at low values of residual oil saturation (ROS) conventional pulsed neutron logging techniques did ...
Investigation of Hydraulic and Mechanical Cement Integrity: An Advanced Computational Study
(2021)
Cement sheath is a significant barrier to maintain the zonal isolation of wells, preventing severe consequences such as kick (or influx) accidents, environmental contaminations, and safety threats. Many previous investigations ...
Dual-porosity approach to wellbore stability in naturally fractured reservoirs.
(2002)
The naturally fractured reservoir was treated as a dual-porosity medium consisting of the primary rock matrix system and the fractured system. Assuming the matrix and fractures in the fractured medium to be 'separate and ...
Wellbore Cleanout in Inclined and Horizontal Wellbores – The Effects of Fluid Rheology, Inclination, and Solids Density.
(2019-08-30)
Recent technical improvements in the drilling process have allowed drilling of high inclination and horizontal wells with longer laterals. The frequency of such wells has increased over time due to their advantage of ...
