Paper presented at the SPE Hydraulic Fracturing Technology Conference and Exhibition, February 1–3, 2022
Paper Number: SPE-209158-MS
... Abstract Horizontal wells with multi-stage longitudinal fractures have been widely used to develop low-to-moderate permeability sandstone formations in enhanced oil recovery schemes. A long-held misconception exists that high fracture conductivity is not essential to well productivity...

... of fracturing operations. Using actual drill cuttings samples from an Eagle Ford well, we have measured the fracture conductivity of mixtures of proppant and drill cuttings for a wide range of drill cuttings fractions. The cuttings-sand mixtures were evaluated following a modified API RP-61 procedure...

..., conductivity, permeability and width. Fracture conductivity is the product of the permeability of the proppant and the closed fracture width on proppant. Since proppant transport, availability, and cost have presented challenges for supply chains and operators, new regional sand mines have been started...

...? 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 lengths...

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...
