Boulanger) To: Lamont/Penn State 4D Seismic Monitoring Consortium Members From: Roger Anderson and Peter Flemings Subject: January 10, 1996 Meeting of the Consortium We are pleased to invite you to the next 4-D Seismic Monitoring Consortium Meeting on January 10, 1996 at the Shell E&P Training Center at the Shell Woodcreek facility, 200 N. Dairy Ashford in West Houston (just nortth of I-10). We are planning a full day's meeting (agenda in Attachment #1) with general consortium discussions in the morning and a hands-on, multiple workstation School on "How-to-use the Lamont 4D differencing software" in the afternoon. A proprietary handbook will be provided to each participant. All are invited for the morning meeting, but we must restrict each company to only those most interested in the actual operation of the software in the afternoon -- because of a limited number of workstations. We also ask that each company's delegation consist of at least one person proficient in the operation of the AVS visualization software that forms the backbone to our code. Could you let us know who will be coming via return e-mail (to roach@ldeo.columbia.edu) or fax (914-359-1631) so Shell can make refreshment and lunch arrangements, as well. There are hotel facilities, nearby, at the Houston Marriott Westside, 13210 Katy Freeway at Eldridge, (713) 558-8338. Meeting attendees, please make your own arrangements, as needed. Attachment #1: Schedule for 4-D Meeting, January 10, 1995, Houston, Texas 8:00 am - 1. Status - Introduction and summary of data aquisition and contract status. (Roger Anderson/Peter Flemings) 2. Results - Summary of research results since the July meeting A. Geologic characterization (Andrew Hoover, PSU) B. Amplitude analysis around zapped surfaces (Tucker Burkhart, PSU) C. Volumetrics and a proposed horizontal well path (Roger Anderson) D. Volumetric inversion study (Wei He, Lamont) 10:30 am - 3. Future Steps - Discussion of direction of 1996 research plans. In particular, what do do about Service Company participation 11:00 am - 4D SOFTWARE SCHOOL 4. An introduction to the operation of the software backbone-AVS (Liqing Xu, Lamont) 12:00 pm - Lunch 1:00 pm 5. Instruction in how to use 4-D differencing software, with demonstrations and an exercise for the class at each stage of the processing sequence (Lamont) 4:00 pm 6. Feedback/Questions/Directions Attachment #2: 4-D Project December 5, 1995 Report #5 1. 4-D Meeting - Penn State and Lamont Doherty met on December 5, 1995, to discuss the status of 4-D research. See below for details. 2. Status of Data Acquisition - a. Paper and digital logs for South Timbalier 295 have arrived and been archived at Penn State. b. Shell's Grover and Timberwolf 3-D surveys (original 1988 processing and 1995 reprocessed versions) have been received at Lamont in segy form for loading into Landmark (.3dv) format. Lamont will load these surveys into AVS and is presently working on merging into a Landmark Project. c. Lamont has received the 1994 Western 3-D seismic survey over the South Timbalier 295 field, and has transmitted a 16 bit Landmark project of it to PSU. d. Texaco has released to Penn State a seismic inversion of their EI 338-339 3-D survey. e. We continue to negotiate with Diamond/PGS for a copy of the 1994 reshoot of the EI 330 study area for Lamont/PSU. There is a proposed collaboration agreement in draft form circulating between PGS and Lamont that would have PGS joining the consortium. GECO so far has refused to participate if another service company is allowed in. We are reapproaching them from higher in the Schlumberger organization, and will further discuss how to handle the service companies at the January meeting. Attachment #3: Summary of Lamont-Penn State Meeting on 12/05/95 The third monthly Lamont-Penn State 4-D Seismic meeting was held on December 5, 1995 at the East Mountain Inn in Wilkes-Barre, Pennsylvania. Presentat the meeting were Roger Anderson and LiQing Xu of Lamont Doherty, and Peter Flemings, Andrew Hoover, Tucker Burkhart, and Steve Nelson of Penn State. The meeting began with brief reports of each group's progress. Penn State has been working on constructing Sw maps, as well as maps of perferation depths and shut-in dates for wells producing from the JD and LF sands within EI blocks 330 and 331. These maps will be used to better understand the production history from these sands. Penn State has also continued to work on the differencing of the Pennzoil EI330 and Shell EISOI seismic surveys. Lamont Doherty has been working on reloading, and rebinning the "Roice 8" seismic survey from Pennzoil (a 32 bit dataset in transit from Pz), but has primarily been concentrating on the correction of bugs in the SEG-Y reader spotted during the beta-testing going on at Shell's Bellaire lab and at Exxon (EPR). Liqing Xu has also completed and transmitted to the test sites updated normalization and equalization modules. Lamont is also concentrating on the completion of Wei He's thesis. The goals and responsibilites for the next month are incuded on the following page. The primary focus of the meeting was to plan for the January 10 meeting in Houston. A summary of data aquisition, results, and future steps will precede a clinic on the use of the Lamont 4-D seismic differencing software. 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. P.B. Flemings contact Chevron, Pennzoil, and Shell (Kuzio - 331 data) 6. P.B. Flemings contact Wei He about seismic/velocity problems 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. Map the KE on all 3 seismic surveys 9. produce velocity plots for each seismic survey (velocity differencing) 10. Produce amplitude and reflection strength maps for the JD, KE, and LF 11. Get TDT logs for block 330 from Pennzoil 12. Get production data for block 338 (Paul Hicks) 13. Load South Timbalier data (well data) 14. Write monthly report 15. Ask Shell Offshore for South Timb. production, TDT, deviation, mud weight, and leakoff data 16. Examine sonic and density logs (on paper) in 330/331, compare to core, extend with cross plots 17. Correlate sands in JD, examine J1D, and make saturation maps Responsibilities for Lamont Doherty: 1. Rebin and normalize the EISOI, and Roice 8 surveys within the cross over area, then transfer to Penn State 2. Acquire seismic data from Diamond/PGS 3. Get 32 bit reprocessed Western Data from Pennzoil for the EI330 4. Get contracts signed 5. Create segy and 32 bit Landmark project for South Timbalier 6. Prepare a wellpath for horizontal well along property line from Texaco A platform in EI 338 to the 330/331/337/338 4 corners 7. Once 32 bit Pz dataset is in hand, prepare new "unclipped" 8 bit "Roice 9" dataset. Cheers, Roger N. Anderson 914-365-8335 1-800-SKY PAGE access code 107334#
