Hydraulic fracturing of poorly consolidated formations: Considerations on rock properties and failure mechanisms.
(2005)
This dissertation addresses the issue of hydraulic fracturing stimulation of poorly consolidated formations. First, a complete review about the mechanical properties of such formations was performed. Typical ranges of ...
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 ...
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. ...
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 ...
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 ...
