- W3093669630 abstract "Abstract Quantifying Formation Damage due to drilling can be of a great importance as it affects the decision whether to perform production stimulation or not. In order to calculate formation damage, a well test is usually performed which will require a long sequence of high cost operations that will cause a delay in the start of production. This research aims to present a new approach through which Formation Damage can be calculated by using permeability and pressure data acquired through wireline formation tester (WFT) along with the conventional well logs. The approach is applied on Sitra field that is located in the Egyptian western desert. The reservoir of interest is a middle cretaceous oil-bearing sandstone reservoir that was penetrated by 70 wells. The first step was building permeability model that is based on the WFT mobility data. Permeability data points acquired along with the calculated porosity were used to divide the reservoir into different hydraulic flow units (HFUs). Using the mud weight and the WFT pressure data, the drilling overbalance pressure is calculated for each well and only the ones with minimum drilling overbalance were used in this step. The next step was creating electro-facies model for the reservoir through indexed and probabilized self-organizing map (IPSOM) using a suite of lithology-indicating well logs analysed to their principal components then associating these electro-facies to the HFUs. Porosity-Permeability relationships were then derived for each HFU and used to calculate continuous Permeability data curves for all of the wells in the field per each electro-facies. This model now presents the original reservoir Permeability around each well without being disturbed by formation damage due to the drilling process. Difference between the model Permeability and the one calculated from the WFT, (ΔK), was then plotted as a function of the overbalance (ΔP) and a relation between (ΔK) and (ΔP) is derived. In the depleted wells, the permeability reduction was higher than the initial pressure wells. Using this equation, (ΔK) can be quantified for each formation pressure with knowing the mud weight. The results were then compared to the production data before and after performing hydraulic fracturing and the results were analysed. Through this approach, quantitative value of the Formation Damage can be calculated without any well tests performed which saves time and cost. Finally, a cut-off value for the formation damage that requires production stimulation is estimated from wells history and by plotting (ΔK) as a function of (ΔP) we can design the mud weight to keep the formation damage below this value which will eliminate the need for stimulation since it will hugely minimize the cost of the completing the well." @default.
