METHOD FOR ESTIMATING INFLOW PERFORMANCE RELATIONSHIP (IPR) OF SNAKY OIL HORIZONTAL WELLS

摘要

An apparatus and a method of formulating an empirical correlation model that estimates inflow performance relationship (IPR) of a snaky well. The model provisions for determining inclination and azimuth direction of the snaky well. A plurality of grid models is simulated for a predetermined well bottom-hole pressure. The grid models are validated by comparing the response of each grid to the response of a horizontal well. Sensitivity analysis is performed to determine the impact of the snaky well parameters on the IPR of the snaky well. Additionally, regression analysis is performed based on the sensitivity analysis in order to determine Vogel based quadratic coefficient that estimates the IPR of the snaky well. A transformation of the snaky well parameters is performed in order to determine a sum of squared errors, whereafter a linear weighting of the transformed parameters is computed to determine a correlation parameter of the empirical model.
