... Abstract Complex fracture networks are usually created using hydraulic fracturing in tight oil reservoirs. The fracture networks between individual stages are considerably different. It is difficult to characterize individual-stage fractures using rate analysis. The production performance using...

... Abstract Hydraulic fracturing optimisation requires addressing numerous challenges including characterising geomechanical parameters and defining optimum perforation intervals for fracture initiation, proper selection of fracturing fluid and proppant, optimising fracture geometric parameters...

... Abstract Hydraulic fractures created during completion operations are assumed to produce back to the original well. While multi-well pad completions increase efficiencies, it complicates fracture connectivity between wells. The proximity of newly completed wells to a pre-existing producing well...

... 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 One of the challenges when performing hydraulic fracturing is treating reservoirs that are close to a water-bearing zone. Unfortunately, uncontrolled fracture height growth adversely affects many treatments and often increases the probability of water influx. This risk of fracture...

... 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...

... Abstract The commercial development of unconventional oil and gas reservoirs using multiply fractured horizontal wells is vital to meeting the world's energy demand. However, the modeling of hydraulic fracture propagation and the production from such fractured wells still poses a challenge...

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 Proppant transport and distribution within fractures is an important part in hydraulic fracturing. At present, the majority of the experiments and simulations are applied to parallel planar fracture consideration. The transport and distribution of proppant within tortuous fractures...

... 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...
