Resistivity data is normally used to evaluate water saturation using porosity values from porosity logs (neutron and density). Determination of initial oil (gas) in place is based on hydrocarbon saturation, porosity and thickness obtained from openhole logging data for a given drainage area. It is important not only to determine the initial hydrocarbon in place, but also to define the existing hydrocarbon moveability, indicating the recoverable hydrocarbon and its type. This paper presents a new approach of hydrocarbon moveability factor (HCM). This factor is derived from shallow and deep resistivity data. The relation F = a/φ m is correct in water saturated zone. In partially saturated zones this relation becomes invalid and it will give the apparent formation resistivity factor (Fa). Based on this idea the hydrocarbon moveability factor (HCM) has been derived. With scale goes from 0.0 to 1.0, it is found that for HCM less than 0.75, hydrocarbon is moveable and for HCM greater than 0.75, the hydrocarbon is immoveable. When HCM is less than 0.25, the moveable hydrocarbon is gas and for HCM greater than 0.25 and less than 0.75, the moveable hydrocarbon is oil. Field examples have been analyzed with the HCM factor. These field examples demonstrated the contribution of HCM in the field of hydrocarbon type identification and determination of hydrocarbon moveability from openhole resistivity logging.

P161 LMR- A ROBUST RESERVOIR PROPERTIES INDICATOR IN CARBONATE RESERVOIRS Abstract 1 The role of LMR (Lambda Mu Rho) method as a tool for characterization of carbonate reservoirs has not been established. In this study we analyze a carbonate reservoir in the south-west of IRAN to examine the feasibility of LMR for reservoir property estimation and lithological characterization. Of particular interest was to apply this methodology in an area where reservoir is of a low reflectivity and acoustic impedance alone fails to separate high from low porosity zones. Lambda-Rho (λρ) and Mu- Rho (µρ) attributes were computed from both rock

We have modified the normal-moveout (NMO) equation for both P-wave and converted-wave (C-wave) data to handle surface elevation changes, and we have implemented this equation in our velocity analysis and NMO correction programs. For the C-wave case, we have also developed a new velocity analysis method that combines NMO correction and common conversion point (CCP) binning with a set of trial γ (Vp/Vs) values, thereby reducing errors introduced by the approximate asymptotic conversion point (ACP) binning method. This procedure has been successfully applied to P-wave and C-wave field data from western Canada and the Colombian Foothills. The benefits are both prestack and poststack. Stacked sections from synthetic and field data that have been processed using these modified equations show better focusing and event continuity. Furthermore, since the events on the moveout-corrected gathers are flatter, longer offsets can be retained for AVO analysis. The improved gathers also enable a more robust residual statics calculation.

In addition to determining porosity and its bound and free-water components NMR logs have been applied to distinguish pore fluids such as gas condensate and high or low viscosity oils. The influences of hydrocarbon types may dominate the behaviors of the T2 relaxation times and unfortunately may interfere with the ability to obtain pore size distributions and bound fluid contents.

P023 A DISCUSSION ON THE SHEAR- TO COMPRESSIONAL-MODE (SP): THEORETICAL PRACTICAL AND ECONOMIC Abstract 1 While it is very common to acquire process and interpret compressional-mode (P) data that have been converted to the shear-mode (S) the reciprocal scenario S to P (SP) is very uncommon. We discuss some of the practical economic and theoretical issues associated with the SP mode. Since P-wave seismic is the standard within our industry SP will likely only be available when nine component data are being acquired. The two main advantages of SP over PS would be that we have a controlled source polarization
