... with various heterogeneity and correlation lengths are generated. UT-COMP is able to solve the compositional model, despite the permeability difference between the fracture and matrix being six orders of magnitude. Multiple cycles of CO 2 huff-n-puff are simulated and compared with production by primary...

Paper presented at the SPE Unconventional Resources Conference-USA, April 10–12, 2013
Paper Number: SPE-164544-MS
... Abstract This paper demonstrates the value of seismic data to define heterogeneous earth models for tight shales, improve reservoir quality and completion quality mapping, and to guide decisions of wellbore placement and completion design. The process includes quantitative classification...

Paper presented at the SPE Americas Unconventional Resources Conference, June 5–7, 2012
Paper Number: SPE-154582-MS
... ″Heterogeneity in lateral wellbores is primarily controlled by wellbore geometry and vertical variations in rock characteristics, which occur at an extremely small scale in shale reservoirs. Abstract Perforating a horizontal well in the Marcellus shale is typically performed using bare...

... using the dynamic-slippage approach of Ertekin et al. (1986) and the method of Javadpour (2009) . Strictly speaking, apparent permeability changes are a function of Knudsen number, as mentioned above. An effective method for identifying reservoir-scale heterogeneities is the interpretation...

... to monitor the migration of fracturing fluid into the reservoir formation. It is generally expected for low permeability formations to show strong capillary forces due to their small characteristic pore radii, but this driving mechanism is in competition with the low permeability and spatial heterogeneities...

... of the radius of drainage concept in well test analysis ( Lee, 1982 ). The streamlines are computed from the pressure and velocity distribution derived from finite difference simulation. This makes the approach completely general and capable of handling complex spatial reservoir heterogeneity and arbitrary well...

Paper Number: SPE-75718-MS
... predictions for individual wells can be off by more than 50%; however, the technique accurately predicts the combined infill production estimate from a group of infill candidates, often to within 10%. The accuracy of predicted infill performance decreases as heterogeneity increases and increases...
