... Abstract Super-k (carbonate zones of extremely high permeability) can significantly enhance recovery per well in the Ghawar Field. These zones present a challenge at the onset of normal water arrival as the water contribution from these zones dominates the flow in the wellbore—causing either...

... numerical simulator is developed to model this process. The capillary pressure, relative permeability and residual saturations of both phases are considered as functions of IFT and wettability, which are correlated to the surfactant and salt concentrations based on the data obtained from laboratory...

... Abstract Horizontal wells are thought to be necessary in formations with low-permeability to increase the recovery and reduce the risk of drilling a dry hole. The horizontal well may cross natural fissures. Although hydraulically fracturing horizontal wells in such formations is a risky job...

... Abstract Relative permeability provides important information for understanding the dynamic behavior of two-phase flow. EOR technology featured by polymer flooding, surfactant flooding and ASP compositional flooding requires relative permeability data to characterize the flow behavior...

.... Such practices consist of seeking the complex relationship between the fracture index and some geological and geomechanical drivers (Facies, porosity, permeability, bed thickness, proximity to faults, slopes and curvatures of the structure) in order to obtain a fracture intensity map using Fuzzy Logic and Neural...

... Abstract This paper introduces a method to fracture more than 30 zones in a single well per day and also how to fracture low permeability zones when the impermeable barrier(s) to high permeability and high water cut zones are only about 0.5 m thick and not create channels in the cement sheathe...

... Abstract PDVSA operates the RG-231 and AM-102 wells, located in eastern Venezuela. The wells are characterized by stratified reservoirs and complex geology due to the presence of low permeability and porosity.
