Paper presented at the SPE Low Perm Symposium, May 5–6, 2016
Paper Number: SPE-180223-MS
... Abstract A two-dimensional, mathematical model that considers transient flow under subdiffusion towards a horizontal well that produces a rectangular drainage region through multiple fractures is considered. Subdiffusive behavior expressed through a fractional constitutive flux law is intended...

... intermediate strength ceramics using standard and modified API RP 19-C crush resistance tests. During testing, load cell volumes range from the standardized 4lb/ft 2 to the modified 0.5 and 0.25lb/ft 2 . 0.5 and 0.25lb/ft 2 volumes simulate proppant behavior in hydraulic fractures with frac widths...

Paper presented at the SPE Low Perm Symposium, May 5–6, 2016
Paper Number: SPE-180242-MS
... Abstract Quantification of secondary mineralization or cementation within natural fractures has not been considered in previous petrophysical dual porosity models. This is however of paramount importance as morphology of the fractures indicates that they can be open, partially or completely...

Paper presented at the SPE Low Perm Symposium, May 5–6, 2016
Paper Number: SPE-180243-MS
... Abstract The key in unlocking unconventional reserves is to create massive fracture surface area. During the fracturing treatment, a huge volume of fracturing fluid is pumped to generate fractures and then followed with a large amount of proppant to provide enough conductivity for reservoir...

Paper presented at the SPE Low Perm Symposium, May 5–6, 2016
Paper Number: SPE-180238-MS
... Abstract The successful development of unconventional reservoir relies on the massive hydraulic fractures which provide high conductive paths and large contact area between matrix and wellbore. Since well production always shows a steep decline after the early high flow rate, refracturing can...

Paper presented at the SPE Low Perm Symposium, May 5–6, 2016
Paper Number: SPE-180265-MS
... Abstract Modeling transient flow of horizontal wells with complex fracture networks is attractive and challenging topic for economically exploitation of low permeability reservoirs. Previous works have been done by employing analytical, semi-analytical and numerical models to solve this problem...

... Shale appears to be gas-charged throughout its thickness in Canyon Creek Field. The entire Baxter interval is highly overpressured (0.72 to 0.88 psi/ft) and exhibits fair to excellent shows of gas during drilling against mud weights of 13 to 17 pounds per gallon. Multi-stage hydraulic fracture...

... can create localized "pressure sinks." When a nearby infill well is fractured, the hydraulic fracture grows towards areas of lowest stress (the depleted area), which can damage the parent well. Subsequently, the production potential of the new well is decreased because it is now draining from the same...
