Taheri and V.A. Sajjadian, SPE, NIOC Use of Reservoir Simulation for Optimizing Recovery Performance of One of the Iranian Oil Fields A black oil reservoir simulator has been used to determine the reservoir management and production strategies to optimize the oil recovery from an offshore low porosity, low permeability carbonate reservoir with permeability of 1-3 md and porosity of 5-20%.
Taheri and V.A. Sajjadian, SPE, NIOC WAG Performance in a Low Porosity and Low-Permeability Reservoir, Sirri-A Field, Iran Sirri-A is a large offshore producing field which is located in the Persian Gulf, in Iranian sector, with an OOIP of about 2 MMMSTB. Its reservoir with porosity range of 3-21 percent and a permeability range of 0.1- 3 md is situated in Ilam formation which is a complex limestone formation.
H. Kashani Birgani, S. Sajjadian and A. Jahanpanah Effect of Wettability on Capillary Pressure and Relative Permeability by SCAL Experimental Data Capillary pressure and relative permeability have been measured in core plugs at strongly-water-wet, moderately-water-wet and nearly-neutral-wet conditions. Plug wettability was selectively altered by aging at Swi, in crude oil at an elevated temperature for selected periods of time.
V.A. Sajadian/NIOC Research Institute of Petroleum Industry, A. Danesh, D.H. Tehrani/Heriot-Watt University Displacement Visualization of Gravity Drainage by Micromodel, Investigation of physics of fluid flow in porous media at the microscopic scale is expected to result in significant improvement in our understanding of the macroscopic phenomena observed in laboratory and in the field. To model multiphase flow, and to predict ultimate oil recoveries from reservoir formations more realistically, it is essential to study flow behaviour and fluid distribution at the pore level at various situations.
V.A. Sajadian/NIOC Research Institute of Petroleum Industry, A. Danesh, D.H. Tehrani/Heriot-Watt University Laboratory Study of Gravity Drainage Mechanism in Fractured Carbonate Reservoir-Capillary Continuity In the well fractured carbonate reservoirs the gas/oil gravity drainage from the gas-invaded zone is the dominating oil producing process. When the gravitational forces exceed the capillary forces, the matrix blocks which are surrounded by gas, will release their oil.
Hafizolah Kashani Birgani Reservoir Characterization Study of an Iranian Carbonate Reservoir by SCAL Application Data This paper contains the SCAL of carbonate reservoir field. It includes the main available data, plots of relative permeability, capillary pressure, water saturation etc. The plots, analysis of J-function versus normalized water saturation and the relations applied for these analyses constitute another section.
