Cook Inlet, Alaska. Received mud logs for 40 wells drilled in the 1950's and 1960's. A variety of different scales were involved, many of which were neither linear nor logarithmic. Worked with our digitizing subcontractor to convert paper logs to reliable data. Project handled via over-night delivery and E-mail.
North Slope, Alaska. Entered core plug data for 70 wells, converted data to a "log curve", depth shifted the core data to fit the log curves, and sent data to client in LAS format.
Gulf of Mexico--Deep Water Play. Programmed and applied custom petrophysical model of a small independent to define net sandstone in laminated intervals for 100 wells. Met with client petrophysicist twice during project.
Gulf of Mexico--Shelf. Programmed and applied custom petrophysical model for Original Hydrocarbons in Place for 170 Plio-Pleistocene wells, mostly drilled in the 1970's and without porosity curves. Worked with client data to define bed dip angle for wells and produced computer processed interpretations in True Vertical Thickness. Met with client every 6 weeks.
Gulf of Mexico--Onshore. Petrophysical Field Study for 100 wells. Calculated effective porosity and water saturation curves for 100 wells, only a few of which had porosity curves. Calculated net sand, pore space (PhiH), average porosity, average water saturation and hydrocarbon pore volume for 25 different Miocene zones. Met with major company client every 6 weeks.
West Texas. A geologist for small Midland consulting firm worked in our office to normalize gamma ray and porosity curves for 160 wells drilled from 1950's through 1990's. I provided software and training. The selection of normalization parameters were his. I provided software so that he could explain the whole normalization process interactively to his client.
West Texas. Normalized 1990's vintage porosity and Pef curves for a dolomite reservoir partially plugged with anhydrite. Calculated reservoir parameters. Client operated field under contract with owner. Discussions by phone. Deliver final report and interpreted curves on CD ROM.
West Texas. Derived a porosity curve from 1940's count rate neutron curves for 120 San Andres wells. The results were used for planning a waterflood. Discussions by phone. Porosity curves delivered on CD ROM for use on Geographix software.
New Mexico. Normalized density and gamma ray curves for 4000 wells. Send results to client in Geolog ASCII format.
Wyoming. Created Volume of Shale curve from SP curve. Normalized density and gamma ray curves. Calculated effective porosity and water saturation curves. Presented results on-screen in client's office for discussion. Delivered these curves for 70 wells for use on client's internal Geographix system.
California. Worked with a large Texas reservoir engineering firm to normalize 700 neutron, density and gamma ray curves in a large field with many local changes in deposition, diagenesis and compaction. We provided batch-mode software to client to generate 2000+ cross plots on their HP laser printer for the final report. Met with client's team five times during the course of the project.
Khazakstan. Normalized 100 old gamma ray and count-rate neutron curves to the response of the only available recent western-style log. Numerous run changes.
Australia. Integrated core data and production data with log interpretation for a shallow oil reservoir for the four available wells. After initial meeting, transfer all data via FAX and E-mail.
Brazil, Yemen, China, Gabon, Thailand. Client sent bluelines and any existing digital log data. Working with my digitizing subcontractor, I added curves or parts of required curves that were missing. All curves were depth shifted and sent via E-mail to my client as soon as completed. Client's petrophysicist was able to complete his analysis on schedule because there were no data problems.
