Abstract
Horizontal wells technology has provided motivation for many applications in the Petroleum Industry, in naturally fractured reservoirs, horizontal wells has been used to intersect fractures and drain them and the reservoir effectively. Horizontal wells also allow operators to take advantage of highly heterogeneous layered reservoirs, reservoirs with fractures, reservoir with gas and water coning problems, heavy oil reservoirs water flood and enhanced oil recovery (EOR) application to increase injectivity and improved sweep efficiency.The main objective of this paper is to estimate the three dimensions permeability and skin factor using two different tools first was using Excel sheet by inserting the equation and analysis the flow periods the by using Kappa(ECRIN)software. The results obtained were good matched for two wells and the third well (E38) was hard to be matched in ECRIN but in Excel was analyzed by divided the curves in to three periods, and the other close to each in first and second wells (E37 -E39) when comparison made between Excel sheet and Kappa(ECRIN) software the ky over kz permeability was estimated as 37.41md (ECRIN39.7md) and to tal skin factor-5.15 (ECRIN-7.25) for E37 moreover for well E39 the ky over kz permeability was estimated at 35.5 md (ECRIN 42.4md) and total skin factor -6.19 (ECRIN -7.01). ECRIN software was very hard and didn’t reach to a modelling well E38 because every scattering in pressure derivative, gave permeability 111.3 md in Y dimension in Excel sheet and -1.62 skin factor.
