Paper presented at the SPE Hydraulic Fracturing Technology Conference and Exhibition, February 1–3, 2022
Paper Number: SPE-209128-MS
... A simplification of these Sneddon equations can be made by only focusing on the direction perpendicular to the fracture face, increasing at a distance x in the reservoir ( Equation 5 ). This is the increase in horizontal stress caused by a fracture (Δσ xx ). This method has been presented...

... of hydraulic fracture faces show that the roughness varies systematically in clusters with average cluster separation of approximately 20' along the core. While isolated smooth hydraulic fractures are observed in the dataset, very rough fractures are found to be accompanied by proximal smoother fractures...

Paper Number: SPE-199754-MS
... on convenience. Reorienting the fracture map is a simple operation which involves multiplying the 3D point dataset (vertices of the mesh grid) with the rotation matrix. The principal idea is to rotate the dataset such that the principal components of the data, which align with the fracture face, are oriented...

Paper Number: SPE-189839-MS
.... This experimental observation is an indication that the conductivity damage varies not only with the mineralogical content of the formation, but also with the distribution of minerals along the fracture face. Geomechanical, geochemical, and flow data integration provided a better understanding of proppant...

... This study investigates both components. Understanding the conditions for liquid loading within the fracture will help identify remedial measures, which may be significantly different from remedial measures for reducing liquid blocking at the fracture face. Simulation Setup Cipolla et al...

Paper Number: SPE-152179-MS
... Abstract Nowadays, it is commonplace to say that acid fracture conductivity depends on the fracture face asperities. Does it really depend on it? Almost thirty years ago, someone wrote, "We believe the conductivity measured in these tests is mainly due to the smoothing of peaks and valleys...

Paper presented at the SPE Hydraulic Fracturing Technology Conference, January 19–21, 2009
Paper Number: SPE-119743-MS
... Abstract Conductivity in acid fracturing after fracture closure depends on the contact of the non-uniformly etched fracture surfaces created by the acid. The surface topography of the fracture faces after acid injection is rarely investigated and, therefore, poorly described. The concept...

Paper Number: SPE-106272-MS
...Scaling Laboratory to Field Conditions The acid fracturing process involves several different phenomena, including acid transport along the fracture, acid transport into the rock because of leakoff, convective and diffusive mass transfer of acid to the fracture face, and acid reaction...
