... Abstract The objective of this paper is to investigate how to acquire fracture closure pressure data accurately and cost-effectively in shale development activities. If the injection volume is small during a hydraulic fracturing job, it is a common practice to consider the ISIP (Instantaneous...

... production. Due to the strong heterogeneity, relatively developed weak planes such as natural fractures and bedding fractures, and the large fracturing fluid leak-off, hydraulic fractures usually propagate non-uniformly and non-continuously and form into complex fractures network, making the pressure curve...

... Abstract In this paper, the width and length of a hydraulic fracture are estimated from the analysis of wave propagation from an active to an offset well. The method is based on a Krauklis wave model, which describes acoustic waves, propagating in a narrow layer, filled with a viscous fluid...

... Abstract Unconventional or tight reservoirs are typically developed with horizontal well technology to effectively exploit the reserves, which could not have been economical with conventional vertical wells. These horizontal wellbores are completed with large multiple hydraulic fracture...

.... Fractures in different scales are incorporated in the model by using a hybrid model. Large-scaled hydraulic fractures are handled explicitly, and small-scaled natural fractures are handled using a dual-porosity model. The changing of SRV region and hydraulic fracture networks due to the infill well...

... Abstract High viscosity friction reducer (HVFR) has been used in the hydraulic fracturing fluid to reduce the frictional loss along the wellbore. The success of friction reducers has been demonstrated through research and industrial implementation. However, concerns regarding chemical usage...

..., alternative propped hydraulic fracture designs were tested in three trial wells attempting to ultimately achieve economic production from S1 and H8. One trial well used a conventional nitrogen-energized guar fracturing fluid but with a larger overall job size. A second trial well tested a cleaner hybrid fluid...
