The purpose of the study is to estimate formation properties (porosity and water saturation) of the reservoir zones. Our analysis includes horizon interpretation, synthetic seismogram, seismic attributes, petrophysical analyses and incorporating these information into a Static Geocellular Model for determining the initial hydrocarbon in-place which would help in developing production strategies for improved reservoir management.

Bioturbation is one such type of heterogeneity that greatly influence the flow behavior,which is physical modification in primary sedimentary fabric by animal & organism activity.Our work aims at characterization the same by performing experiments at multiscale namingly from Core level to Pore level so as to ascertain the effects of Bioturbation in the formation, which would help in better volumetric estimates and flow modeling. Based upon the result, it was observed that much of the heterogeneity associated with the rock was cylindrical and ranging in 1-2cm in diameter, aligned vertical to almost vertical to the bedding plane, this enabled vertical core to include them in longitudinal direction while horizontal core in transverse direction. The effect of bioturbation can be understood by analyzing the contrasting values of the horizontal n vertical core. Th...

Bioturbation is a prominent source of heterogeneity existing in hydrocarbon-bearing formation across the world. The effect of bioturbation on the petrophysical properties of the clastic has not been comprehensively understood yet, especially its effect on cementation factor estimation. The precise description of such properties is beneficial in developing better volumetric estimates and optimizing field development planning. The present work discusses an approach to characterize cementation factor in bioturbated clastic Bhuj Formation, Kachchh Basin, India. In order to ascertain the cementation exponent for bioturbated media, an improved triple-porosity model is proposed by quantifying the total porous volume into three components, namely matrix 1, matrix 2 and bioturbated region. An equivalent resistance model is then developed by identifying the series and parallel relation...
