Paper presented at the SPE Hydraulic Fracturing Technology Conference and Exhibition, May 4–6, 2021
Paper Number: SPE-204150-MS
... Abstract The purpose of this paper is to present a technique to estimate hydraulic fracture (HF) length, fracture conductivity, and fracture efficiency using simple and rapid but rigorous reservoir simulation matching of historical production, and where available, pressure. The methodology is...

... based on crush resistance to stress loading and fracture conductivity under various flow conditions while having the lowest possible cost. However, dimensionless fracture conductivity is the main driver of well performance as it relates to proppant selection since it includes the relationship of...

... showed approximately 1,000 psi depletion, confirming that the V1 fracture is "flowing" into the H1 lateral 1,000 ft away. The reservoir simulation history match indicated low fracture conductivity, but enough to improve well productivity and drain oil over 1,000-ft from the H1 lateral. This paper...

In this study, we extend our previous work and derive time-convolution solutions to pressure transient behavior of a closing fracture with infinite and finite fracture conductivity. We show that G-function and the square root of time models...

...? The paper will show how effective fracture lengths are not dependent on propped fracture properties alone. Given the limited effective conductivity resulting from a combination of damage mechanisms, the interaction of the propped fracture conductivity and reservoir inflow dictate effective fracture...

Paper presented at the SPE Hydraulic Fracturing Technology Conference and Exhibition, February 5–7, 2019
Paper Number: SPE-194320-MS
... Abstract During hydraulic fracturing treatments, proppants often settle near-wellbore in low viscosity fracturing fluids (e.g., slick water) and leave a large fractured surface unpropped. Poor placement of proppant could lead to a loss of fracture conductivity and undermine the productivity of...

Paper Number: SPE-194377-MS
... Abstract Creating sufficient and sustained fracture conductivity contributes directly to the success of acid fracturing treatments. The permeability and mineralogy distributions of formation rocks play significant roles in creating non-uniformly etched surfaces that can withstand high closure...

Paper Number: SPE-189839-MS
... Fracture conductivity is a measurement of the capacity of a fracture to flow fluid. It is determined in the laboratory by measuring the pressure drop of a fluid flowing through a uniformly distributed proppant bed within a core sample. The selection of the most suitable fluid and proppant types...

... fracture's resistance to displacement and closure is described by its compliance (or stiffness). Fracture compliance is closely related to theelastic, failure and hydraulic properties of the rock. Quantifying fracture compliance and fracture conductivity under in-situ conditions is crucial in many earth...
