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

Madison Group and the regions have the reservoirs have yielded hundreds of millions of barrels of oil since production started in the 1950s. Historically, it was estimated that these oils were thought to be sourced by the Bakken Shale. However, oil fingerprint including light hydrocarbons and biomarker data clearly show these oils not to be related to Bakken Shale source rocks except in special cases in US fields. However, for the concept of mixing of Madison and Bakken Shale sourced oils in Canadian Williston Basin reservoirs is quite common as a result of lateral migration and trapping of both Madison and Bakken Shale sourced oils. Finally, it was found that there can also be differences in stratigraphic nomenclature particularly the Tilston Member of the Mission Canyon formation.
