Anderson) Lamont/Penn State 4-D Seismic Monitoring Consortium Project Report, May, 1996 (Report #6) 1. May 4-D Meeting - Penn State and met on May 2, 1996, to discuss the status of 4-D research, and to plan for AAPG and the July Consortium meeting. See Attachment #1, "Meeting Notes," for details. 2. January 4-D Seismic Consortium Meeting - The January 4-D meeting at Shell's Woodcreek Facility in Houston was a big success. Thanks to Shell for hosting and to all who attended. The meeting served as a useful tool for introducing everyone to the Lamont 4-D Software and gaining input from our industry partners. Both Penn State and Lamont are working hard to add error analysis techniques to our 4D studies in the future, as a result of the meeting. We are also bringing in our Beta site teams for intensive 3-day working sessions with your data on the Lamont machines. We now have 6 active test sites going, with three more planned for June/July installations. Shell has been to Lamont in March working on the ST case study. Excellent oil/water contact movement was tracked in one reservoir. Images will be mounted in our AAPG booth (see below), and are on the 4d4 homepage under "AAPG Presentation" --use the consortium login and passward. With Shell's help, we also did an error analysis both in the water-wet downdip horizon and in a bio-marker bed above the pay reservoirs. Amoco, Chevron, Exxon, Pennzoil, Texaco, and Unocal, you are next in line, beginning in early June. Its first come, first serve, with Pennzoil scheduled for June 5-7. Do you want another software school during the July meeting, as well? 3. Lamont has formed a "Bridge" company called 4D Technology, Inc. 4D Tech is to be the intermediary between Columbia and oil service companies that are interested in licensing the Lamont 4D software. Columbia owns 88% of 4D Tech, with the remainer distributed to a management team especially recruited from the industry. Randall Neal is CEO and President. He was President of DPC&A, a risk and economic software vendor for the oil industry. Billy Meadow, ex-VP Business Development for BBN, Inc. is now 4D Tech's VP Bus Dev. Don Tuttle is VP Operations. Come by the Lamont 4D Technology booth #340 to meet them and give them any feedback you might have on how to proceed with the service companies. 4. Petroleum Engineer added to Penn State 4D Consortium Team - Paul Hicks, an Assistant Professor of Petroleum & Natural Gas Engineering at Penn State, has joined the 4D Research Team and will work on reservoir modeling. He is an Eclipse pro, and he and a summer student will be modeling a ST reservoir first. 5. Chief Geoscientist added to Lamont 4D Consortium Team - Wei He has successfully completed his defense for his PhD and will receive the diploma at Columbia on May 15th. He has begun full-time work as chief geoscientist within the Lamont 4D Team. His thesis was on the 4D Inversion techniques he developed for this project. A total of 3 patents were filed in Wei's name as a result of his thesis, and one has been granted already. He will give a presentation on his inversion results at the July meeting (see below). 6. Important Consortium Dates - * May 19-22 - AAPG meeting in San Diego. COME VISIT the Lamont 4D TECHNOLOGY Booth (# 340) AT THE AAPG. Please see Attachment #2, "AAPG Schedule" for information on times and locations of Penn State and Lamont 4D science presentations. * July 23 - 4-D meeting in Houston. We will distribute more information on times and place after details are ironed out with the host company. Attachment #1: Summary of Lamont-Penn State Meeting on 5/02/96 The monthly Lamont-Penn State 4-D Seismic meeting was held on May 2, 1996 at the East Mountain Inn in Wilkes-Barre, Pennsylvania. Present at the meeting were Roger Anderson, Wei He, and Albert Boulanger of Lamont, and Peter Flemings, Paul Hicks, Andrew Hoover, Tucker Burkhart, and Steve Nelson of Penn State. One primary goal of the meeting was to plan for the AAPG convention in San Diego, May 18-22. Please see Attachment #2 for details on the location and timing of oral presentations, poster sessions, and information on the Lamont 4D Consortium Booth #340. The meeting began with brief reports of each groups progress. Lamont has been working on constructing amplitude difference maps of the K8-K16 and K40 sands in the South Timbalier Field and has found that the oil-water contact movement is clearly visible in the K40. The K-8-K-16 is more complex, with the first a depletion drive and the second a strong water drive reservoir. The region-grower grows one object for both. We are working on seeing under the top now, but the K-8 is drained in a more "blotchy" manner than the K-40. Lamont has also used well log data as the "hard" informatino to control a full 4D seismic inversion of the Pz and Sh seismic cubes in Eugene Island 330, FBB. Wei He derived predictions of lithology and has plotted the volume of shale and the porosity/effective oil saturation remaining in 1992. Penn State and Lamont have been jointly analyzing the acoustic effects of the hard zone at the top of the LF reservoir in EI 331, with the inversion seeing low impedances under but the synthetic seismogram study not seeing under the bright event. We will report on this at the July meeting. Penn State is characterizing the geology of the K8 and K40 sands and is constructing amplitude maps of these horizons. The production data for the sands has been acquired, and Paul Hicks has joined the group to complete reservoir models of the two sands. Further discussion of how to quantify error bars as part of the normalization procedures led to the conclusion that a standard deviation and signal-to-noise module will be added to Lamont's 4-D software. These statistical analyses will yield information on the amount of error that exists between the two surveys that have been normalized and differenced by extracting statistics in water wet portions of sands continuous with but downdip from reservoirs. The goals and responsibilities of each party are again included below: Responsibilities for Penn State: 1. Transfer interpreted well porosity, lithology, and water saturation data to Lamont Doherty 2. Interpret water saturation and sand/shale ratio data at half-foot intervals in well logs and transfer this information to Lamont Doherty 3. Examine possible `delta-front' lobes of the JD sand and calculate net sand `by lobe' 4. Examine saturation data with corresponding permeability and porosity data 5. Flemings contact Chevron, Pennzoil, and Shell (331 data) 6. Flemings contact Wei He about seismic/velocity problems in LF of 331 7. Map velocity (v), density (r), porosity (f), permeability (k), water saturation (Sw), volume of sandstone (Vs), volume of shale (Vsh) and structure for the JD, KE, and LF sands. 8. produce velocity plots for each seismic survey (velocity differencing) 9. Get TDT logs for block 330 from Pennzoil 10. Get production data for block 338 (Paul Hicks) 11. Write monthly report 12. Ask Shell Offshore for South Timb. TDT, mud weight, and leakoff data 13.

Rebin and normalize the 32 bit Pz and Sh surveys within the cross over area, then transfer to Penn State 2. Continue negotiations to acquire seismic data from Diamond/PGS and GECO?? 3. Inquire with Pennzoil about getting 32 (or 16) bit reprocessed Western Data for the EI330 -- proprietary, if not through consortium. 4. Solve 32 bit Landmark problem with Shell/Pecten 5.
