... (RTA) can be used to extract an estimate for the product of fracture area and the square root of permeability ( Jha et al., 2017 ). If fracture area is known, then permeability can be estimated from the RTA. However, effective fracture area during production is also difficult to estimate...

... resources remains largely unrealized. Recovery factors for unconventional oil and gas wells are typically reported at < 20% in gas shale reservoirs and < 10% in the oil plays. Neutrally buoyant ultra-lightweight proppants have been demonstrated to effectively provide production from fracture area...

... indicators are used, such as the stimulated fracture area, total proppant bed area, the area of the fracture above the bed, etc., to assess the efficacy of a design. This study shows that, depending on the natural fracture density and the stress anisotropy, the benefits of pumping larger volumes of fluid...

... considerably with more effective frac designs that generate and/or sustain a larger contributing fracture area. The findings show that reservoir characteristics, completion, frac design and production practices are the primary drivers of Haynesville well production. In addition, the results indicate...

... viscosity, proppant transported with slickwater tends to settle out resulting in limited propped height. Polymer coated proppants and high drag proppants are emerging technologies that can increase propped fracture areas: Polymer coated proppants achieve very low settling rates due to the hydration...

Previous studies demonstrating that stimulated well performance can be improved by increasing fracture conductivity have generally addressed...

... or control fracture complexity depends on reservoir permeability, the degree of fracture complexity, and un-propped fracture conductivity. The paper also examines the effect of fluid leakoff on maximum fracture area, illustrating potential limits for fracture complexity as reservoir permeability increases...

... Abstract Post-frac production analyses frequently suggest that effective fracture area is significantly less than that designed, implying either the existence of excessive proppant-pack damage or, that the proppant was not placed in designated areal location. The conductive fracture area...
