Petrophysical Properties and Reservoir Modeling of Kala Field,Eastern Niger Delta, Nigeria
Abstract
This research is focused on Petrophysical properties and reservoir modeling of Kala Field Eastern Niger Delta. Data used for this research include 3-D Seismic in Seg-Y and suites of well logs. Normal faults trending NW-SE has been delineated on seismic data of Kala Field. The lateral extent of reservoirs E and F delineated in blocks (A, B and C) was modeled with the results of the petrophysical analysis showing the average petrophysical values of reservoirs in blocks A, B and C in Reservoirs E and F as porosity (25% (A), 25% (B), and C 23%), permeability (291md (A), 300md (B), 1990md (C)), Net-to-Gross ratio (0.74, (A) 0.80
(B), 0.66 (C)), water saturation (45%, ,39%,37%) and Stock tank oil initially in place (54.71mmstb,26.83mmstb, 15.47mmstb,) respectively. The results of the petrophysics suggest that the porosity and permeability values within the reservoirs, indicate accumulation of significant hydrocarbon. It is the findings of this research that horizontal wells be drilled in block C for both reservoir E and F. This suggests that this field may be economically viable, hence may be referred to as prospect.
