Integrated Interpretation of an Iron-Rich Sediment, Jansz-Io Field, Northwest Shelf, Australia G. R. Heavysege* (ExxonMobil Exploration and Production Malaysia) & A. Mills (ExxonMobil Australia) Low Resistivity (LR) and Low Contrast (LC) pays have been identified in many clastic and carbonate reservoirs all over the world. Typical LRLC zones in PETRONAS operated fields show resistivities of 2- 4 Ohmm, which are similar to the resistivities of the adjacent shale beds and very close to the resistivities of the (fresh) formation water bearing zones(1-2 Ohmm). This study is focussed on the investigation of clastic reservoirs in the Malay, Sarawak and Sabah Basins, which are mainly shaly and silty sandstone zones, that were not obvious and not classified as “net pay” from previous conventional formation evaluation techniques. Based on an integrated petrophysical analysis of modern log data (including Nuclear Magnetic Resonance (NMR),Borehole Imaging), and Special Core Analyses (SCAL) data (including electrical, hydraulic and NMR properties), improved concepts and wo rkflows were developed for the identification and evaluation of productive hydrocarbon bearing LRLC zones.
