(2013-07-30)The Eagle Ford play in south Texas is currently one of the hottest plays in the United States. In 2012, the average Eagle Ford rig count (269 rigs) was 15% of the total US rig count. Assessment of the oil and gas resources ...
-
(2013-09-27)Previously unattainable shale gas deposits have become accessible since the late 1990s using a technique called hydraulic fracturing — the injection of chemicals, water, and sand into subsurface shale to free extractable ...
-
(2009-05-15)Shale gas formation exhibits some unusual reservoir characteristics: nano-darcy matrix permeability, presence of natural fractures and gas storage on the matrix surface that makes it unique in many ways. It’s difficult to ...
-
(2014-08-06)In current petroleum industry, there is a lack of effective reservoir simulators for modeling shale and tight sand reservoirs. An unconventional resource modeling requires an accurate flow characterization of complex ...
-
(2012-11-30)Successful development of shale gas reservoirs is highly dependent on hydraulic fracture treatments. Many questions remain in regards to the geometry of the created fractures. Production data analysis from some shale gas ...
-
(2012-02-14)Excess water production is a major economic and environmental problem for the oil and gas industry. The cost of processing excess water runs into billions of dollars. Polymer gel technology has been successfully used in ...
-
(2022-04-13)It is widely recognized that hydraulic fracturing creates a region of altered permeability near the fracture/matrix interface. Although we have a limited understanding, it is believed this region plays an important role ...
-
(2017-12-15)This work presents the development of two new rate-time relations which are based on self-growth limiting time-cumulative relations. This self-limiting feature provides an inherent upper limit on ultimate reserves and ...
-
(2010-01-14)The so-called "Arps" rate decline relations are by far the most widely used tool for assessing oil and gas reserves from rate performance. These relations (i.e., the exponential and hyperbolic decline relations) are empirical ...
-
(2010-10-12)Shale gas has become increasingly important to United States energy supply. During recent decades, the mechanisms of shale gas storage and transport were gradually recognized. Gas desorption was also realized and quantitatively ...
-
(2015-08-24)The Marcellus shale is currently the most productive shale play in the United States. In 2015, the Marcellus shale play led in natural gas production per rig and had the highest shale gas production in the United States. ...
-
(2010-07-14)Many hydraulically fractured shale gas horizontal wells in the Barnett shale have been observed to exhibit transient linear behavior. This transient linear behavior is characterized by a one-half slope on a log-log plot ...
-
(2014-04-29)Early diagenetic carbonate cements can affect brittleness and total organic content in shale reservoirs. Predicting these effects could potentially improve recovery efficiency and field development costs, and decrease the ...
-
(2017-05-10)Recent advances in drilling and well stimulation technologies have led to rapid development of shale formations as an important natural gas resource. However a comprehensive understanding of the source rock geochemistry ...
-
(2012-07-16)Today everyone seems to agree that ultra-low permeability and shale reservoirs have become the potentials to transform North America's oil and gas industry to a new phase. Unfortunately, transient flow is of long duration ...
-
(2010-10-12)Fractured reservoirs have been traditionally idealized using dual-porosity models. In these models, all matrix and fractures systems have identical properties. However, it is not uncommon for naturally fractured reservoirs ...
-
(2015-08-10)In this work, our purpose is to create a "performance-based reservoir characterization" using production data (measured rates and pressures) from a selected gas condensate region within the Eagle Ford Shale (S. Texas). We ...
