Paper Number: SPE-199701-MS
...) production casing with a 4.67-in. ID. This allows a 4-in. or 3 ½-in. semi-flush string to be installed after a cleanout, which is then cemented in place. The plug-and-perforate stimulation approach then allows the well to be stimulated with a higher intensity modern completion and tighter cluster spacing...

... the transition from matrix flow to fracturing. We present a series of model tests on different unconsolidated materials using large cylindrical samples with a diameter of 0.4 m. We changed the permeability of the sample and investigated the effect of cohesion by adding cement to some of the samples. It appeared...

... are introduced into a commercial finite element package through user-defined subroutines. A workflow to derive the required model parameters for both intact rock and cemented natural fractures is presented through inverse modeling of field data. The hydraulic fractures' growth in the reservoir scale...

... permeability. For reference, beach sand is roughly 2000 md, construction-grade cement averages about 0.005 md and shales vary from about 0.000001 to 0.0001 ( Table 1 ). Not every shale has sufficient permeability to produce gas, even with the assistance of hydraulic fracturing. Permeabilities...

... Abstract The goal of this paper is to investigate the near-wellbore phenomena with respect to fracture initiation. The 2D numerical model was developed, which takes into account the interaction of steel casing, cement, and surrounding rock and allows for a curved path of the fracture...
