Economic Evaluation of Enhanced oil Recovery in Sudanese (A) Field

Abstract

The research for tomorrow’s oil reserves has directed the efforts of the energy industry to frontiers beyond the conventional exploration and production strategies. These frontiers are defined not by geography or geology but rather by technology. They are a collection of technologies-involving the use thermal, gas and chemical means for producing more oil-that fall under the broad of umbrella called Enhanced Oil Recovery (EOR). The planning of an EOR project demands a meticulous attention to many problems, thus requiring consideration lead time for studies, evaluations, project design and most of all the economics of these high cost EOR projects. The objective of this study to conduct an economic analysis for candidate major Sudanese field (A) for application of technically approved enhanced oil recovery methods. This field Located in the eastern part of block 6 (Fula sub basin). The geological of (A) field is unconsolidated sandstone.oil properties (API=18˚, viscosity=3000 cp) .So oil is very viscous and screening methods suggest apply cycle steam stimulation to increase production. By performing economic sensitivity analysis on key input variables such as oil prices, operation expenses, capital expenses and production data. With estimated production, capital, operation expenses and financial data, project economics are evaluated; project finding that the revenue for applied cycle steam stimulation in (A) field is 6526 MM USD, NPV=1077 MMUSD and NCF= 893 MMUSD .these values most economic from base case (conventional methods).
