Abstract

Analytical simulation reveals multiple aspects of reservoir dynamic complexity, as well as variability of input-output parameters linked to fluid data and relative permeabilities (Donohue et al., 1995; Houck & Cooley, 1983). The analytical model provides estimates of reservoir production and energy from infill drilling projects and secondary recovery models with lower uncertainty. The material balance was applied to a structural block visualized as a “tank”, represented as a compartmentalized reservoir with gas-in-solution conduction. The study area is a 135-acre structural block located in northwestern Peru, is a solution gas driven volumetric reservoir, which is depleted by 11 producing wells. The model was performed with the historical fitting of production data and pressures, then predictions were obtained with the drilling of five infill wells and the application of a water injection project. The results showed that for the compartmentalized block of the study only 3 wells are the optimal number of infill wells with an individual increase of 52 thousand barrels of oil (MBO) of reserves (above breakeven 46 MBO) with a total investment of 1.8 million USD for the 3 wells, reaching a total profitability of 2.24 million USD. In addition, a water injection project achieves pressure maintenance and incremental reserves of 147 MBO with an investment of 2 million USD, achieving a profitability of 2.105 million USD.
