Abstract
Porosity and water saturations are the most important petrophysical parameters of hydrocarbon reservoirs that accurate assessment of them in hydrocarbon reservoirs is an effective tool, important and efficient for industry experts, in the context of a comprehensive study of reservoirs and production and management process of reservoir. In this study, using data from five wells of Mansuri oil field, and using the sequential simulation Gaussian method and using Petrel software, the trend of Porosity and water saturation changes in the mentioned field for four zones was simulated. Also the average maps for each zone have been created that results of the simulation parameters in this map showed that highest average porosity is 0.1401 and 0.2756 at least saturation of water is related to zone 1. Finally result of the simulation indicates the Zone 1 is of the best reservoir Zones.
Highlights
Investigation and simulation of petrophysical properties is one of the main aspects of hydrocarbon reservoirs full studies which is performed in most oil companies
The present study investigates the modeling and the petrophysical parameter of the Asmari formation in Mansuri oil field: South western of Iran (Figure 1)
The porosity and water saturation variation maps shows that in porosity values distribution map, its maximum value starts at Southeast of the field, passing through the center it ends at Northwest of the field (Figure 6) which is the effect of Paleofacies which improves the porosity of the region due to different lithology (Figure 7)
Summary
Investigation and simulation of petrophysical properties is one of the main aspects of hydrocarbon reservoirs full studies which is performed in most oil companies. Petrophysical properties of reservoir rock such as lithology, porosity, permeability, net pay thickness and percentage of water and oil saturation obtained from well logs interpretations can be modeled by simulation of the reservoir [1] [2]. Tabatabaei petrophysical parameters, a three-dimensional (3D) view of reservoir properties can be obtained that plays an important role in the development of reservoir flow patterns. By simulation of these parameters, the reservoir potential areas can be identified and used in the development of hydrocarbon oil fields
