... are of equal length but otherwise of unidentical properties. Each well has an arbitrary number of uniformly spaced identical, finite-conductivity fractures and is surrounded by a stimulated reservoir volume. Properties of hydraulic fractures and stimulated reservoir volumes may vary from well to well...

Paper Number: SPE-215172-MS
.... However, with the increased drill time, the wellbore damage due to drill-in fluids may become significant. To maintain sustained production rate by removing near wellbore damage and creating highly conductive long path from the well deep into the reservoir, vast majority of these wells are subjected...

...., 2021 ). The conductivity of such fractures is maintained by asperities which form during the reaction of the acid with formation. Those asperities prevent a fracture from closure and allow the effective transportation of the hydrocarbons to the wellbore. In addition to asperities, the dissolution...
