| Gulf Coast reservoirs exhibit low resistivity pay behavior typically related to depositional and diagenetic controls. Data from these reservoirs is controlled primarily by pore geometry. Better understanding of complex variation in pore geometry within different facies is very important in improved reservoir description. Permeability, which is very important to effective reservoir description, is a function of porosity and geological factors such as pore geometry, mineralogy, etc.;The hydraulic unit approach (unit with similar pore geometry) is applied in Hutchins Peareson Trust No. 1. A regression model of Flow Zone Indicator (FZI), a fundamental parameter that incorporates most geological parameters, is generated from wireline logging responses. These regression models are applied at every corresponding hydraulic unit to predict permeability in an uncored well, England Unit ;This technique is successfully applied in the Gulf Coast of Texas. |
