... increase closure pressure fracture complexity hz marcellus barnett shale bj service company Introduction The Marcellus Shale, also referred to as the Marcellus Formation, is a Middle Devonian-age black, low density, carbonaceous (organic rich) shale that occurs in the subsurface beneath much...

... Abstract The Barnett Shale play in north central Texas has 14,382 wells which were originally primarily vertical wells. Currently 68% of the wells are horizontal wells. This Barnett Shale has significant changes in performance and quality as produced fluid type changes, as the depth changes...

... that contrasts the application of numerical reservoir simulation and advanced decline curve analyses to illustrate issues associated with conventional production data analysis techniques when applied to unconventional reservoirs. Selected examples from the Barnett shale are included that incorporate...

... Abstract Formation evaluation (FE) while drilling is an established technique in horizontal well orientations for unconventional reservoirs such as the Barnett Shale. Due to constrained well economics, special care is taken to acquire cost-effective information quickly to maximize lateral...

... Abstract Fort Worth Basin Barnett Shale fiscal success and completion methodology have matured to the point that analog plays all over the North American continent are being actively sought and tested. It is probable that additional potential plays outside the current active areas exist...

... hydraulic-fracture diagnostic tools are successfully applied in the Barnett Shale. Indirect tools such as 3-D fracture models are often used to estimate gross fracture height and length and can work well in some cases. However, because of the complexity of fracture geometry in the Barnett, today's...
