Databases of Kansas oil fields were assembled with the purpose to aid in the selection of leases for the laboratory studies. Databases were assembled in an Excel spreadsheet from a database derived from public data and maintained by the Kansas Geological Survey (KGS). [KGS’s database can be queried by the public at http://www.kgs.ku.edu .] Our two “working” databases present the following information for Kansas oilfields.
| Field name |
| Producing zones (up to 10 zones) |
| Discovery date |
| Total cumulative oil production (bbls) |
| Total cumulative gas production (mcf) |
| Area (acres) |
| Total number of wells |
| 2008 oil production (bbls) |
| Number of oil wells in 2008 |
| 2008 gas production (mcf) |
| Number of gas wells in 2008 |
| Location by county (up to 19) |
Reservoirs are broadly defined as a producing zone in a particular field. The “reservoir” version of the database has one reservoir (a field-producing zone combination) on each row. There are 9,765 reservoirs (rows in the database) by our definition. It is noted that the production figures in this database are for the field and are listed only once in one of the producing zones for that field. The “field” version has all producing zones (reservoirs) in a field listed on the row for that field. This representation is not unique but allows for some manipulations to be easier. This presentation gives 6,536 fields (rows in the database).
We have found that types of information derived from the public records did not assist in the identification, evaluation or selection of leases for chemical flooding application. A major issue with the data is the allocation of the oil produced in a field to the producing zones (reservoirs). Also, the zones were identified when the well was initially completed and subsequent completions in other additional zones are not known. We will determine if there is a reasonable method to allocate oil produced from a field to the various production zones (reservoirs). If successful, this will allow for the identification of the resource base for chemical flooding in Kansas.
