Experimental and numerical evaluation of shape memory polymer for lost circulation treatment in geothermal wells
(2022)
Lost circulation presents formidable challenges to drilling operations, especially in high-temperature and fractured formations. Lost circulation events increase the nonproductive time (NPT) and the total cost of drilling ...
HLD-NAC Based Solutions for Surfactant Flooding
(2016-04-05)
Established technologies like primary recovery methods using gas pressure and other natural forces in the reservoir, and secondary recovery by water flooding can only approximately recover one-third of the crude oil present ...
Experimental and numerical simulation study of microbial enhanced oil recovery using bio-surfactants.
(2005)
A 2-phase, 10-component microbial enhanced oil recovery numerical simulator was modified to include reservoir salinity and facilitate surfactant and polymer injection. The effects of reservoir brine salinity and divalent ...
Development and properties of a self-bursting pellet as agglomerated from coal fines by use of an organic binder.
(1980)
In all aspects of the mining, processing, and handling of coal, fine particles are generated that are in many cases wasted. These fines can be agglomerated into strong and durable pellets by use of an organic binder which ...
FRAC HIT ANALYSIS IN SHALES: WOODFORD, MERAMEC AND WOLFCAMP FORMATIONS
(2020-07)
Frac hit was initially coined to refer to the phenomenon when an infill well fracture interacts with the adjacent well during the hydraulic fracturing process. But, over the years, its use has been extended to any type of ...
Three-Dimensional FEM Modeling of Geothermal Reservoir Stimulation Using Stochastic Fracture Networks and Continuum Damage Mechanics
(2014-08)
Unconventional reservoirs are gaining more and more attention in recently years. Pore pressure and temperature variations in unconventional reservoirs during stimulation are of great importance in reservoir exploration and ...
FUNDAMENTAL HYDRAULIC FRACTURING CONCEPTS FOR POORLY CONSOLIDATED FORMATIONS
(2012)
This dissertation examines -by means of the discrete element method- the mechanisms that govern hydraulic fracturing in poorly consolidated formations. The motivation to take on this project was the widely reported ...
Development of a three-segment hydraulic model for cuttings transport in horizontal and deviated wells.
(2001)
This study describes the model development for each segment, the combination of each model, the solution, and the simulation results of the combined three-segment model. To ensure a comprehensive understanding of the effects ...
Behavior of fluids in clay-hosted nanopores: insights from molecular dynamics
(2021-05)
Our understanding of fluid behavior and transport in shales, especially in organic or kerogen pore systems, has grown rapidly over the last few years. Yet, given the prevalence of inorganic material that often hosts the ...
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 ...
