Abstract
This research presents the results of an investigation of fracture parameters and how it affects the production rate or recovery from a hydraulically fractured well. The problem that occurs without taking into consideration the important role each of these parameters play in the ultimate recover from a low permeability reservoir. In dealing with hydraulic fracturing design, it is neces sary to be able to determine the area of fracture extent to be able to calculate or estimate the productivity index of the well.
The aim of the study is to show the relationship between the fracture area which is one of the important fracture parameters and the productivity index of a well. Field data was acquired, an analytical method was applied and mathematical correlations was established to determine the parameters of interest, and Microsoft excel was employed for computational purposes to ensure error elimination. For the analysis of data, an investigation was also made to ascertain the various basic parameters and their respective values from four different wells that was fractured. Their different fracture area and productivity index were computed using the equations established and the field data acquired to attest the accuracy of the adopted correlation. Graphs were also plotted to show a clear relationship between the fracture area and productivity index. The results from the research shows that an increase in the area of fracture extent will variably increase the production rate or recovery from the well. That is the fracture area varies directly with the well’s productivity index.
