The Economic Evaluation of the Efficiency of the ASP Chemical Flooding in DERO Field

Abstract

In this research, economic evaluation of the efficiency of the ASP chemical flooding method applied on the oil-producing Jaribeh formation of DERO oil field was performed. The theoretical study firstly included complete explanation of objectives and justifications of the research, reference study related to the economic aspects of applying the mentioned method, overview of DERO oil field (lithostratigraphic, petrophysical, and depositional properties as well as reservoir indexes of Jaribeh reservoir in the mentioned oil field).The economic study however, included the following axes: Determination of sequence of chemical solutions and liquids proposed to be injected in the pilot area chosen for studying, determination of volumes of chemical solutions and liquids proposed to be injected in the pilot area, determination of the ideal batch of the ASP solution proposed to be injected in the pilot area, proposed scheme of the injection process, choosing a pilot in DERO field and determining its main reservoir characteristics, calculating volumes of chemical solution and liquids injected in the pilot area, calculating oil quantities expected to be produced from the pilot area as a result of applying the ASP flooding method, and calculating cost of chemical materials needed for the ASP flooding process in the pilot. As a result of this study, the additional quantity of oil produced by applying the ASP flooding method in the pilot was determined as well as the additional cost of an oil barrel resulted from using chemical materials in the mentioned flooding process that is (1.93 $/bbl).
