BACKGROUND AND OUTLINE OF TECHNICAL COMPONENTS The Hugoton and Panoma Fields (Figure 1), Permian Chase and Council Grove Groups, respectively, are premier natural gas resources and constitute the largest gas producing area in North America. Since 1928, the gas fields of southwestern Kansas, including Hugoton, Panoma, Bradshaw and Byerly, have produced 27 trillion cubic feet of gas. These reservoirs are economically important to the State of Kansas and major gas producers, including the Sponsors in this project. Even with a long history of substantial production, there is no publicly available field-wide study of how best to explore, produce, and regulate the Permian gas reservoirs. This study is designed to provide the knowledge and technical base required for intelligent stewardship, generation of new opportunities, and continued improvement in recovery strategies in the Hugoton and Panoma Fields. Results of earlier collaborative work by the Sponsors and the Kansas Geological Survey (under the Hugoton Initiative project) demonstrate that the entities work together effectively to generate useable digital data and solve technical problems (see Council Grove (Panoma) reservoir poster at http://www.kgs.ku.edu/PRS/publication/2003/ofr2003-30/index.html). By utilizing digital well data (tops and LAS files), cores, and core analyses organized under the auspices of the Hugoton Initiative, the Sponsors and KGS are well on their way towards efficiently and accurately modeling a very large and complex reservoir system. This earlier work involved the development of 1) extremely large set of digital data (e.g., horizon tops, pressure and production data), 2) core based facies classification scheme that is tied to petrophysical properties; 3) empirically derived, facies-constrained porosity-permeability-saturation equations; and 4) geostatistical facies prediction and processing methods, all critical input data for 3D modeling work. In close collaboration with the Sponsors, we propose to complete the Panoma (Council Grove) reservoir model through simulation, and to leverage the knowledge gained to model the Hugoton (Chase) in a similar manner. Functional, accurate models and simulations based on sound science and engineering and should 1) answer fundamental questions regarding the continuity of the two reservoir systems that are regulated separately; 2) provide a technical basis for improved reservoir management and improved regulation; and 3) assist placement decisions for replacement and/or infill wells. Deeper oil and gas pools of the Hugoton Embayment are also a significant and increasingly important asset to the Sponsors and the State of Kansas. For the purposes of this project, the Hugoton Embayment is defined as the 15 southwestern counties of Kansas (i.e., Finney, Grant, Gray, Greeley, Hamilton, Haskell, Kearny, Lane, Meade, Morton, Scott, Seward, Stanton, Stevens, and Wichita). While the Hugoton Embayment Permian produce 75% of Kansas gas it also yields half the annual non-Permian gas production and nearly a fourth of the oil production. The proposed catalogue of the pre-Permian oil and gas pools (Deep Pools of the Hugoton Embayment – DPHE) will provide basic production, geologic and engineering data on the deep pools of the region and serve it conveniently, online. In addition to static basic data the web-based catalogue of pools will provide dynamic maps and data visualization pages that pull data directly from the Kansas Geological Survey database in real time. The catalogue will be linked to the KGS data system providing a convenient portal to a suite of online tools available on the KGS web site. The KGS will draw on its existing tools and experience in web-based applications like those in the Digital Petroleum Atlas (see

Arroyo Field example http://www.kgs.ku.edu/DPA/Arroyo/arroyoMain.html) and GEMINI (http://www.kgs.ku.edu/Gemini/index.html), both U.S. Department of Energy funded projects. Understanding of the Hugoton and Panoma south of the Kansas border is no better than that north of the border. Southward expansion of the Permian gas systems modeling and simulation studies will provide Sponsors with assets in those areas a cost-effective analysis of those regions as well as a better understanding of the Kansas reservoirs, particularly those in close proximity to the border. Due to data and budget constraints it is anticipated that these extensions would use 20-30% of the well density for structure and geometry as did the models on the Kansas side, but a similar sample density of the more important digital well log and core data. Still, the Oklahoma and Texas expansion will require substantial tops and digital data gathering and management, tasks accomplished earlier in Kansas under the Hugoton Initiative. The KGS will work with Sponsors, public and private entities to assemble the required data set in the most cost effective manner. SCOPE DETERMINED BY LEVEL OF FUNDING Whether all facets of the Hugoton Asset Management Project are completed is dependent on the level of funding achieved through Sponsor contributions. Below is a prioritized list of the four principle components in the study and their respective total Sponsor funding requirement (over two years if modeling and simulation studies are not expanded; three years if expanded to include Oklahoma and Texas Panhandles). Total budget for two or three year project • Geologic and engineering models for Permian gas systems $120,000

$60,000 $60,000 $45,000 $80,000 $365,000
Accountability and Timeline Sponsors and the KGS, tempered by availability of funds and final scope of the project, will mutually agree upon research directions and priorities for the project. Should the modeling and simulation project be funded, the Council Grove will be completed in the first year and the Chase in the second. Expansion to Oklahoma and Texas would require a third year. Projected timelines without the Oklahoma-Texas expansion are as follows:

Specific technical end products provided by the KGS for the Deep Pools of the Hugoton Embayment, a web-based dynamic catalogue of all deep (pre-Permian) pools having in excess of one MBOE ultimate recovery, will include the following: 1) General data in static format including, but not limited to, discovery well and date, reservoir parameters (e.g.: thickness, average porosity, permeability, BHT and water resistivity), fluid analysis (water, oil, gas), general well and pool drilling completion and production practices, and core and thin section images. 2) Dynamic links to production data and associated display tools. 3) Dynamic well profiles with standard log curves as well as other data when available. 4) Dynamic well location and geologic maps. 5) Dynamic cross sections. 6) Other visualization and data assembly tools as they become available. 7) Convenient links to other applications, data and visualization tools on the KGS web site. Interaction and Reporting An important aspect of the project is collaboration between the Sponsor(s) and the KGS and unfettered access to the people doing the project work at the KGS. This is crucial in the short term for refining and executing the project plan. In the longer term both Sponsor(s) and KU/KGS personnel benefit from interaction. Since the proposed study is a truly collaborative effort, data transmission and direct communication will be ongoing as needed. More formal meetings will be scheduled as follows: 1) Regularly scheduled (bi-monthly) conference calls between technical team members. 2) Work session meetings where technical team member(s) travel to the other’s site as required for effective collaboration and transfer of ideas and data. 3) Bi-annual meetings of technical team and other interested parties from KGS and Sponsors will be scheduled either in Dallas, Houston or Lawrence.
6
Technical Publications Ongoing reports will be made public through paper and poster and presentations at professional society technical meetings. Submission of article(s) to scientific journals is anticipated. Budget Sponsor(s) cost for the project, excluding their own personnel, outside consultant fees, and any additional data purchased, is $365,000. KGS Personnel and Infrastructure KGS researchers involved have broad petroleum geology and computer experience and have a long track record of addressing geological, geophysical, petrophysical and petroleum related question in Kansas and the Hugoton-Panoma area. A large number of the key personnel have extensive practical petroleum industry experience. Individual resumes are available on request. The Kansas Geological Survey and KU Energy Research Center have an extensive computer network with all the necessary hardware and software to successfully undertake the project. A complete list of all computing assets and other technical equipment available to the project is available on request.
