Paper presented at the SPE Hydraulic Fracturing Technology Conference and Exhibition, February 1–3, 2022
Paper Number: SPE-209126-MS
... Abstract Many have attributed the success of hydraulic fracturing in unconventionals to the development of increased reservoir contact area through complex fracture networks with significant shear-enhancement of flow on preexisting natural fractures. Core samples recovered in recent field...

Paper Number: SPE-209131-MS
... Abstract For simplicity, planar fractures are usually used for simulating well performance. This is clearly an oversimplification for naturally fractured formations. Core data from both HFTS 1 and 2 show that a much more complex fracture network is created. In this work, a novel three...

... stress in subsurface formations. Because of the heat exchange during the test, ultra-low permeability of the host rock, and natural fractures, the conventional methods yield inaccurate results in geothermal reservoirs. In this paper, we present a new methodology based on the signal processing approach...

Paper Number: SPE-194361-MS
... Abstract Micro-seismic data suggest that complex fracture networks are formed frequently in unconventional reservoirs due to the interaction of hydraulic fractures (HF) with natural fractures (NF). Understanding this interaction is critical for optimizing fracturing design. It is generally...
