... Abstract High viscosity friction reducers (HVFRs) have been recently gaining more attention and increasing in use, not only as friction-reducing agents but also as proppant carriers. Reusing of produced water has also been driven by both environmental and economic benefits. In Marcellus Shale...

... Abstract Increased interest in correlating rheological properties to the prediction of proppant transport and/or friction reduction performance produces sporadic and isolated experimental evidence. Obtaining accurate results specifically for viscosity, proposedly representative of proppant...

... et al., 2017 ). VFRs stand out in comparison with a conventional system in the fact that design changes are much more dynamic. Viscosity changes can be easily adjusted according to VFR loading to reduce chemical volume or cost. Viscosity may be increased to place a higher proppant volume...

This study proposes to use three candidate ultra-lightweight proppants ULWPs to enhance the fractured well performance in unconventional reservoirs. In step 1, the current sand pumping design is input into an in-house P3D...

... for their applicability in horizontal development wells. Its purpose is to deliver a better perception of fracture geometry and interactions between payzones that are separated by potential fracture barriers. Multiple vertical wells employed the use of diagnostics in the form of proppant tracer, production logging...

.... Cohesive Zone Method (CZM) has been used for modeling fracture propagation. The presented model distinguished the propped part from the unpropped part of the fracture. At the beginning of flowback, the proppants may not be completely compacted in early shut-in time. Thus, permeability evolution during...

... Abstract In shale formations, operators are constantly seeking new technologies to improve proppant transport and conductivity in order to boost production. A novel technique known as surface modified proppant (SMP) has been pumped in more than a dozen wells in the United States, with proven...

... on surface treating pressure and proppant transport. Both laboratory results and field studies of FR and boosters are discussed. Additionally, it was observed that tailored booster chemistry appears to increase FR viscosity significantly, thereby helping ensure better proppant transport during fracturing...

The slip, due to the nano-roughness coating on proppant grain surface, allows for the trapped fluid in the matrix to flow ( Mokhtari and Tutuncu, 2018 ). Length of a fracture is an important factor for the reservoir fluids to flow into the wellbore...

... Friction reducers (FRs) are used to decrease the amount of horsepower required to move a hydraulic fracturing fluid through a formation at a fixed flow rate. Though FR viscosity is not a crucial consideration in proppant transport when used before the perforations in slick water applications, FR viscosity...

... led to consideration of an alternative, non-aqueous fracturing fluid. A hydraulic fracturing process utilizing 100% LPG as a fracturing fluid to carry proppant into shale or a coal seam or other water sensitive pay zone was developed. The new LPG fluid could be easily viscosified with oil gelling...
