Innovative laboratory research and fluid breakthroughs have improved carbonate matrix stimulation technology in the recent decade. Since oil gas wells are stimulated often to increase output maximum recovery, this has resulted acidizing is a less costly alternative hydraulic fracturing; therefore, it widely employed because of its low cost fact that may restore damaged their previous productivi...

a synthesis of well logs was carried out and drilling mud weight data were analyzed to figure outanomalous high fluid pressure within the triassic evaporitic cap rock (the dashtak formation) andstudy its impact on the geometry of anticlinal traps in the gas rich gavbandi province located in thesoutheast part of the zagros mountains. the results indicated that the location of anticlinal traps at...

a proper understanding of reservoir fluid phase behavior is the first crucial step in the development and production of an oil/gas field. this paper addresses the challenges and errors associated with the fluid sampling that may arise before, during and after the sampling operation. for this aim, dst and pvt data of exploration and production wells of a supergiant offshore gas condensate reserv...

Hydraulics play an important function in many oil field operations including drilling, completion, fracturing, acidizing, workover and production. The standard API methods for drilling fluid hydraulics assume either power law or Bingham plastic rheological model. These models and corresponding hydraulic calculations do provide a simple way for fair estimates of hydraulics for conventional verti...

Carbonate reservoirs are one of the most important fossil fuel sources, and acidizing stimulation is a practical technique for improving recovery carbonate reservoirs. In this study, improved two-scale continuum model, including representative elementary volume (REV) scale model upscaling used to study process with an isolated fracture. Based on comprehensive discussion presented effect physica...

maybe viscosity in drilling fluid is the most important parameter because cutting removal from well are task of viscose fluid. if viscosity of fluid is less than particular value, cutting will settle down in well and drilling operation will be stopped. in this study, synthesis of alumina/polyacrylamide nanocomposite through solution polymerization method was performed. rheological behavior of m...
