Project Description: In this project, you will be working with well log, PVT, and rock data for your volumetric analysis of the reservoir. Your task is to analyze the provided data, make interpretations, and draw conclusions based on the information available, and then compile your findings into a short report. We encourage you to explore the data thoroughly and apply your analytical skills to make informed assessments about the reservoir. Please note that this dataset is provided for educational purposes and does not represent real-world geological data. This project (worth 10% of the final grades) must be performed individually. Objectives: Through this project, students will complete the following tasks: 1. Identification of different zones and corresponding thickness of each layer 2. Determination of oil and gas in place of the reservoir Useful equations: Archie's equation: Gas in place: n 1.47 Rw Sw= mRt G[SCF] = Oil in place: Area [ft] x thickness [ft] xox (1 - Swi) ft Bgi SCF] Area[ft]x thickness [ft] 5.615 xx (1-Swi) N[STB] = bbl BOSTB Porosity calculation using density log: $ = Pmatrix Pbulk Pmatrix Pfluid Notes: As the neutron density log has not undergone calibration, it is employed solely for qualitative porosity comparisons across various formations. To quantify the porosity of each layer, the density log must be utilized. If your analysis of the log data suggests the existence of a gas zone within the reservoir, please assume an initial water saturation of 10% and a gas gravity of 0.77 in that zone for the purposes of this project. It is known that all layers of the hydrocarbon-bearing formation are composed of dolomite lithology with a density of 2.87 g/cc. 1 SET 1 Well log data: Resistivity, spontaneous potential (SP), neutron porosity, and density logs were run in the well, providing the following data. The depth recorded in feet is represented on the vertical axis of the graphs.
