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 ...
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. ...
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 ...
Simulation of asphaltene deposition in petroleum reservoirs during primary oil recovery.
(2000)
In this study, a polymer solution model for asphaltene precipitation was used to simulate the experimental data of asphaltene precipitation due to pressure depletion. The results predicted by the polymer solution model ...
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 ...
Anisotropic effects upon amplitude-vs-offset response in realistic earth models.
(2000)
The derivation and computation of the reflection coefficient for general anisotropic media is described along with software written to implement the computation. This program is then used to compare the reflection response ...
A Heuristic Simulation and Optimization Algorithm for Large Scale Natural Gas Storage Valuation under Uncertainty
(2015-04-23)
Natural gas storage valuation is an optimal scheduling of natural gas storage facilities. It is a complex predictive decision making research problem since it involves the financial decisions and the physical storage ...
Laboratory imaging of hydraulic fractures using microseismicity.
(2002)
Developing robust algorithms and software for locating the coordinates of hydraulic fracturing-induced microseismic events, and for simulating the first motion of the induced waveforms were central tasks for this research. ...
Production performance of horizontal wells in gas-condensate reservoirs.
(2002)
Gas condensate reservoirs go under two kinds of changes in their lifetime. The phase change and the physical properties change. Both the changes have been handled in this study using the pseudopressure function integral ...
