Question

MISSISSIPPIAN MISSION CANYON FORMATION, WILLISTON BASIN, U.S.A (75 pts). A wildcat well in the Williston Basin is drilled to the Mississippian Mission Canyon Formation at approximately 9,297 to 9,409 ft which was decided from the cuttings and LWID measurements. Cores were taken and based petrophysical analysis, two potential zones containing hydrocarbon shows were identified, the upper and lower Mission Canyon. From the core data, it was decided to stop drilling and run wireline logs to assess the potential of the Mission Canyon for production of oil and gas. Your company agrees with your suggestion to run a complete log package, which are shown below, including GR, Caliper, resistivity logs, 1- sonic and neutron-density measured in LST settings. Complete the following tasks.- Show your calculations, and elaborate on your answers for each Complete the following tasks- Show your calculations, and elaborate on your answers for section: Fill out the resistivity table. a. b. Determine the lithology from mineral identification "MID" plot and M-N lithology plot. which propose that the rock may be composed of more than two significant minerals c The Pickett plot is created from the log information (page 5), find and m from the plot if a I and n-2 . [F a/(pND)"] and PND is the average value of ND porosity from the logs. d. Calculate water saturation, bulk volume water (BVW), the moveable hydrocarbon index (MHI) which is equivalent to HSI (HC saturation Index), moveable oil/hydrocarbon saturation (MOS/MHS), and residual oil/hydrocarbon saturation (ROS/RHS). Decide lithology and grain size based on these values. Which depth is the suitable reservoir! Additional information can be found in the log header in page 3. 11Page

Explanation / Answer

In the diagenetic evolution and the system of the Mission Canyon Formation has been complex and began during its deposition in the Mississippian and has extended to the present. Early diagenesis was controlled, to a large extent, by microfacies and depositional environment. Later diagenesis which was similar to all kinds of microfacies. Porosity was created by dissolution during the three stages of diagenesis only used for the submerged to be reduced or destroyed by cementation, mainly by sparry calcites. The nature of the pore in the waters (meteoric, marine, mixed, or brine) responsible for the diagenetic changes were interpreted from stable isotope and trace element analyses.
