There will be open registration from 8:00 a.m. to 8:30 a.m., however, pre-registration is encouraged. Total attendance in the core workshop is limited.
The registration fee for the first day workshop is $60 and for the second-day core workshop is $90. This fee covers lunch, break refreshments, and a copy of the each day's workshop manual. For more information contact Alan Byrnes (785-864-2177, abyrnes@kgs.ku.edu) or Melanie Cromwell at the KU Energy Research Center (785-864-4445, melanie_cromwell@kgs.ku.edu).
Overview
Incised-valley fill (IVF) systems represent major reservoirs in southeast and southwest Kansas. These reservoirs are shallow (<6,000 ft), easy to drill, well defined by upper and lower bounding units, and can exhibit excellent porosity and permeability. While reservoirs in these systems can be broadly characterized as sandstone filling meandering incised-valley channels, in reality these reservoirs can include stacked packages of very different lithofacies that were deposited in the range of environments associated with incised-valley systems. By examining several incised-valley systems it is possible to better understand general IVF and regional patterns and the nature of controls that cause local variations. Understanding the properties of the lithofacies, the nature of the sequences, and reservoir architecture is important for many aspects of exploration, reservoir management, secondary and enhanced recovery, and property evaluation.
Day 1 - Reservoir Characteristics of Morrow/Incised-Valley
Fill Plays
The first day of the workshop will involve presentations on various geologic, log and core petrophysical and engineering aspects of IVF reservoir systems in the Morrow, Cherokee, Chester, Tonganoxie, and modern analogs including the following presentations:
| Title | Presenter | From |
| Sequence stratigraphic framework of IVF systems | Dr. W. Lynn Watney | Kansas Geological Survey, Lawrence, Kansas |
| Oil and gas production from IVF reservoirs in Kansas | Paul Gerlach | Kansas Geological Survey, Lawrence, Kansas |
| Analysis of Morrow Incised-Valley Reservoirs | Dr. Roderick W. Tillman | Consulting Geologist/Stratigrapher, Tulsa, Oklahoma |
| Incised valleys in the Cherokee Group, southeastern Kansas | Dr. Anthony Walton | University of Kansas, Lawrence, Kansas |
| Tonganoxie IVF system, northeastern Kansas and modern estuarine analogs | Dr. Allen Archer | Kansas State University Manhattan, Kansas |
| The Chester Formation in South Eubanks Field | Ernie Morrison | Kansas Geological Survey, Wichita, Kansas |
| Interpretive aspects of seismic coherence and related multitrace attributes | Dr. Susan Nissen | Kansas Geological Survey, Lawrence, Kansas |
| Evaluation of Morrow Reservoirs in the Midcontinent by modern wireline logging tools | Willard Guy | Kansas Geological Survey, Lawrence, Kansas |
| Integrated Petrophysical methods for analysis of reservoir microarchitecture - Chester Formation, southwest Kansas | Dr. John Doveton | Kansas Geological Survey, Lawrence, Kansas |
| Routine and special core petrophysical properties of Kansas IVF reservoirs | Alan Byrnes | Kansas Geological Survey, Lawrence, Kansas |
| Waterflood charactertistics of the Morrow, Stewart Field, Kansas | Dr. G. Paul Willhite | University of Kansas, Lawrence, Kansas |
Day 2 - Morrow Incised-Valley Core Workshop
The second day will be a full-day core workshop conducted by Rod Tillman and Allen Archer using cores, logs, and data from Morrow Stateline Trend fields (SW Stockholm, Moore Johnson, and Arapahokan) with emphasis on:
- Interpretation of facies in core, especially tidal and estuarine facies
- Examples of tidal facies and recognition
criteria - Correlation of core facies with wireline logs
- Integration of core facies, porosity and permeability data, and log response
A review of Stateline trend oil field will be presented by Tillman, along with details of reservoir distribution and recognition of facies in core. Tillman has been involved in studying the Stateline Morrow for over a decade and has published several papers on the Morrow.
Examples of tidal facies and recognition criteria will be presented by Allen Archer using core examples from Kansas. Archer is one of the world's leading researchers in the effects of tides on the earth and reservoirs in particular. He is widely published and has run numerous core workshops.
The core workshop will be approximately half lecture/discussion
and half excercises to be solved by teams. Integration of the
core interpretations with log and other subsurface data will
be the prime focus of team excercises.
Participation in the core workshop is limited so pre-registration
is encouraged
