A comparative review on the petrophysical evaluation of thinly bedded reservoirs using conventional and 3d explorer data

This study demonstrates the efficiency of the multi-component induction tool (3DEX) that simultaneously measures the vertical and horizontal resistivity of the formation, by presenting a comparative petrophysical evaluation of thinly bedded reservoirs using Conventional logs and 3DEX data acquired from two different fields of which one is an oil-bearing reservoir formation from Olu field in the Niger Delta province and the other is a gas-bearing reservoir formation from Balda field in North Sea. Various graphs and charts were displayed to showcase the difference between the two evaluation techniques. From the oil-bearing reservoir field the 3DEX results indicate an average hydrocarbon reserves of 83% while the Conventional interpretation techniques presents an average of 17% and in the gas field the 3D-Explorer model gives an average of 53% and the Conventional model shows 47%. These results have demonstrated the effectiveness and successful application of the multi-component induction tool(3DEX) in evaluating thinly bedded reservoirs for effective decision making and proper well placing and performance predictions.
