Productivity Prediction of Horizontal Well with Sulfur Deposition in Sour Gas Reservoir

Abstract:

With the development of sour gas reservoir, the utilization of horizontal well technology has a great significance. The accurate prediction of the productivity of horizontal well in developing sour gas reservoir will become more and more important. In this paper, productivity prediction formulas of the horizontal well are established with considering the effect of sulfur deposition on permeability. The effects of the length of horizontal well, the effective thickness of the reservoir, elemental sulfur deposition and reservoir heterogeneity on productivity can be analyzed by established formulas. According to the field case, the calculating results of improved Joshi’s equation approaches the real productivity, which means that it could be used to predict the productivity of horizontal well at initial stage during sour gas reservoir development. The results can be used as a reference for the development of similar sour gas reservoir.
