Development of Field Petrophysical Model Using Enhanced Data Analysis: A Case Study On Kailashtila Gas Field
Petroleum and Mining Engineering Department, Shahjalal University of Science and Technology, Sylhet 3114, Bangladesh
ABSTRACT
Characterization of reservoirs or analysis of petrophysical characteristics includes determination of; lithology, porosity and permeability, etc. In this study, reservoir characterization is done by evaluation of well log data to obtain reservoir rock and fluid properties, such as porosity, permeability, lithology and stratigraphy on a foot by foot or meter by meter basis using Rock work 14 software. Log data of total four production wells of Kailashtila(KTL) field (KTL- 2, KTL- 3, KTL- 4, and KTL- 5) were analyzed. The Stratigraphic correlation modeling shows that the Kailashtila Gas Field is of uniform thickness in horizontal extend. Matrix density is estimated ranges from 2-2.65 gm/cc and resistivity of ranges from 20-50 ohm-m, reflecting the sandstone lithology with minor inclusions of shale. However, Density-Neutron (D-N) cross plot suggests that the lithology is mainly sandstone with little limestone. The porosity and permeability were determined which ranges from 20-35% and 100-500 millidarcy (md), respectively, which showing the good yielding capacity of the reservoir.
