Rawal, Chakra (2012-07-16)Problems involving coupled thermo-poro-chemo-mechanical processes are of great importance in geothermal and petroleum reservoir systems. In particular, economic power production from enhanced geothermal systems, effective ...
-
Ortega, Alexis (2015-03-25)Hydrochloric acid (HCl) is the most commonly used stimulation fluid for high-temperature wells drilled in carbonate reservoirs due to its high dissolving power and low cost. However, the high corrosion rate of HCl on well ...
-
Pilisi, Nicolas (2010-01-16)The supply and demand situation is crucial for the oil and gas industry during the first half of the 21st century. For the future, we will see two trends going in opposite directions: a decline in discoveries of conventional ...
-
Wei, Yunan (2010-01-16)With the rapidly increasing demand for energy and the increasing prices for oil and gas, the role of unconventional gas reservoirs (UGRs) as energy sources is becoming more important throughout the world. Because of high ...
-
Noynaert, Samuel F (2013-08-13)Since the 1980’s horizontal drilling has been a game-changing technology as it allowed the oil and gas industry to produce from reservoirs previously considered marginal or uneconomic. However, while it is considered a ...
-
Sarwar, Muhammad Usman (2012-02-14)Unbroken gel and residue from guar-based fracturing gels can be a cause for formation damage. The effectiveness of a fracturing treatment depends on better achieveing desired fracture geometry, proper proppant placement ...
-
Tobola, David Philip (Texas A&M University. Libraries, 1988)The usual objective of well logging is to determine the physical properties of underground formations and the nature of the fluids contained within the pore space. Porosity and fluid saturations are needed to estimate ...

Developing a tight gas sand advisor for completion and stimulation in tight gas reservoirs worldwide Bogatchev, Kirill Y. (2009-05-15)As the demand for energy worldwide increases, the oil and gas industry will need to increase recovery from unconventional gas reservoirs (UGR). UGRs include Tight Gas Sand (TGS), coalbed methane and gas shales. To economically ...
-
Yao, Caiyin (Texas A&M University. Libraries, 1992)Two methods have been developed for evaluating formation permeability using log data. One method is an integrated simulation technique that can be used to analyze time-lapse logging measurements. The second method involves ...
-
Pongthunya, Potcharaporn (2009-06-02)One of the most critical parameters in the success of a hydraulic fracturing treatment is to have sufficiently high fracture conductivity. Unbroken polymers can cause permeability impairment in the proppant pack and/or in ...
-
Assem, Ahmed Issam Elsayed Salama (2017-06-28)Proppants are solid particles, extensively used in hydraulic fracturing operations. These materials possess specific mechanical strength indispensable in keeping induced fractures open, resulting in up-surged well production. ...
-
Holditch, Stephen A. (Texas A&M University. Libraries, 1976)Laminar flow of fluid through reservoir rock can be described using Darcy's Law. If the flow is not laminar, the Forchheimer equation should be used to describe the system. The Forchheimer equation contains a term, β, which ...
-
Cheng, Kun (2012-07-16)As gas production from conventional gas reservoirs in the United States decreases, industry is turning more attention to the exploration and development of unconventional gas resources (UGR). This trend is expanding quickly ...
-
Yalavarthi, Ramakrishna (2009-05-15)Every tight gas well needs to be stimulated with a hydraulic fracture treatment to produce natural gas at economic flow rates and recover a volume of gas that provides an acceptable return on investment. Over the past few ...
-
Ozobeme, Charles Chinedu (Texas A&M University, 2007-04-25)Normally in tight gas sands, water production is not a problem but in such low permeability reservoirs it is difficult to produce gas at commercial flow rates. Since water is more viscous than gas, very little water is ...
-
Tschirhart, Nicholas Ray (Texas A&M University, 2005-11-01)The petroleum engineering literature clearly shows that large proppant volumes and concentrations are required to effectively stimulate low-permeability gas sands. To pump large proppant concentrations, one must use a ...
-
Espinel Diaz, Arnaldo Leopoldo (2012-02-14)When estimating a waterflood performance and ultimate recovery, practitioners usually prepare a plot of log of water-oil ratio vs. cumulative production or recovery factor and extrapolate the linear section of the curve ...
-
The impact of gravity segregation on multiphase non-Darcy flow in hydraulically fractured gas wells Dickins, Mark Ian (Texas A&M University, 2008-10-10)Multiphase and non-Darcy flow effects in hydraulically fractured gas wells reduce effective fracture conductivity. Typical proppant pack laboratory experiments are oriented in such a way such that phase segregation is ...
-
Tian, Yao (2010-07-14)In 2007, the Barnett Shale in the Fort Worth basin of Texas produced 1.1 trillion cubic feet (Tcf) gas and ranked second in U.S gas production. Despite its importance, controls on Barnett Shale gas well performance are ...
-
Filbrandt, Joseph Daniel (2012-02-14)The production of sand can be a major issue in many young, unconsolidated sandstone formations where there is little to no cement holding the individual sand grains together. When such reservoirs are produced, quite often ...
