Multi-component induction parameters on multi-component electromagnetic (EM) tools are now commercially available that provide additional induction logging measurements. Coaxial and coplanar measurements necessary to accurately characterize measurements enable the estimation of resistivities parallel anisotropic near-wellbore formation properties.

High dielectric permittivities are formation conductivity measurements. Formation electrical caused by an accumulation of ions outside the grain. In conductivity is obtained from an in-phase voltage shaly non-source rocks, the dielectric enhancement normally measurement. The quadrature (out-of-phase) portion of seen at lower frequencies arises from polarization the measured signal is usually small, and its main use of a double layer of counter-ions. A controlled laboratory is as a skin-effect correction at higher formation conductivities.

A high porosity confined slope channel complex sandstone reservoir is currently undergoing a 24 well development in the Erha Field, OPL 209, deepwater Nigeria. Three conventional cores have been acquired in the field, but none in gas bearing section. Fo

These groups can be subdivided according to the variations that affect some of their properties. The rocks of the Heavy Crude Northern Belt have similar geologic history, composition and reservoir properties. In their oil fields, five fundamental groups of INTRODUCTION electrofacies are distinguished. Three of them are related with carbonatic rocks, important for production, In the study of the oil fields, it is important to associate one is the regional seal, and in the other predominates similar parameters with analogous layers, always than the siliceous rocks.

In many cases in the process of petrophysical inversion it is necessary to calculate P-and S-wave velocities as To verify the simulation technique we have compared functions of porosity and mineral skeleton properties.

In recent years, however, triaxial induction tools have been built, that allow The NCMA area lies on the Patao-KK High within the for multi-component measurements, giving the West Tobago Basin, located north of Trinidad and to the Petrophysicist the possibility to use both horizontal and southwest of Tobago (Figure 1). This basin contains a vertical resistivity measurements to handle the low number of gas-bearing reservoir quality sands deposited resistivity pay situation.

These were also related to geological facies described within the cores. The key for determining electrofacies is core and log data integration. Recognition of electrofacies in a wide Therefore, it was possible to determine a variety of variety of depositional environments can be achieved electrofacies in all wells of the fields based on through inductive and deductive methodologies. In two calibrated core and log data. Furthermore, vertical and different fields located in Argentina and Venezuela, horizontal variations were recognized and correlated open hole logs (spontaneous potential, gamma ray, with seismic data.
