... impact of geomechanical stresses on key production parameters in an effective way. This will lead to a more robust simulation model and history match for the life of the reservoir. Core plug samples from carbonate formation were tested for conventional measurement (porosity, permeably, and grain density...

Paper Number: SPE-159641-MS
...Introduction Oil-water delineation, especially in the exploration and appraisal phase of an oil development is very crucial to determine the oil in place for reserve assessment and subsequent development for the field. Most carbonate formations are highly layered (stratified vertically...

... etched fracture might close completely at bottomhole producing pressures. Also, carbonate formations with more than approximately 30 percent insoluble components are generally not good candidates because overall acid-etched fracture conductivity may be impaired due to low solubility and also the release...

... prediction of water and hydrocarbon saturations. In many carbonate formations, the effects of restriction may be quite pronounced making the standard fluid characterization with diffusion-relaxation maps questionable. The restricted-diffusion model is applied to laboratory measurements on carbonate core...

Paper Number: SPE-134495-MS
... Several mechanical treatment methods are currently used for stimulating carbonate formations: Abstract Recently, a new fiber-laden, self-diverting, and viscoelastic acid has been successfully used for matrix acidizing of highly heterogeneous carbonate formations The fibers have been...

... of the chemical solution into the complex naturally fractured carbonate formations. The technique improves leakoff control into large natural fractures, dominant wormholes and high permeability zones, and results in deeper acid penetration and more effective vertical coverage. The degradable fibers completely...

... at in-situ conditions. Productivity decline in an acid-fractured well is an integrated response of the elastic, plastic, and creeping responses to the applied stress. About 30-40% of production rate decline occurs during a short time as a result of primary creeping of the acid-softened carbonate formation...
