Title: Computer-based system for exploration, optimization, and reserve estimation at the Bakhar field, South Apsheron, Azerbaijan, SSR
Abstract: Abstract This paper presents a review of computerized geostatistical methods for determining optimum exploration drilling patterns, and for calculating oil and gas reserves at the Bakhar field. Experimental variograms of porosity and hydrocarbon saturation are calculated and modeled. Ordinary kriging then is used to determine global estimates of each parameter for different horizons of the reservoir. Universal kriging is used to map the nonstationary elevation of formation tops. With prior knowledge of a parameter's spatial correlation structure, the kriging variance can be used as a criterion for determining the optimum number and location of wells for reserve estimation purposes. This is the basis of an iterative algorithm for an optimum drilling plan in the exploration and development of a field. Geostatistical methods are well suited to spatial estimation problems in hydrocarbon exploration and production and have been implemented in a comprehensive software package.
