General Field Information | |
| Geologic Province: | Las Animas Arch |
|---|---|
| Exploration Method: | Seismic refinement of subsurface interpretation |
| Surface Formation: | Neogene Loess |
| Oldest Formation Penetrated: | Mississippian |
| Drilling Casing Practices: | Mud rotary tools penetrate to TD in the Mississippian. The various Lansing-Kansas City and Cherokee Zones of interest are drillstem tested individually as encountered. Generally, 4 1/2 inch production casing is set into the Mississippian and the Cherokee Johnson Zone is perforated and acidized. As of 1985, the Johnson Zone was completed open hole in two wells. Where the Johnson Zone does not produce, longstring is set through the base of the Kansas City and the Lansing-Kansas City Zones are individually perforated and acidized. |
| Electric Logging Practices: | Gamma Ray Neutron Guard Caliper log run on all wells. Limited use of Compensated Density, Micro-Seismogram and Acoustic Velocity logs. |
| Comments: | Other shows: Sample shows in Toronto and Lansing "B" zone. Oil recovered on drill stem test in Lansing "F" zone. |

Producing Formation:LANS.-K.C. |
| Depth Top: | 4033 feet |
| Geological Age: | Lansing and Kansas City Groups, Missourian Stage, Upper Pennsylvanian Series |
| Depositional Environment: | The producing zones of the Lansing/Kansas City are carbonates, deposited during the regressive phase of the cyclic sedimentation that characterizes much of the Pennsylvanian section in the Mid-Continent region. These regressive limestones were deposited on a broad, gently sloping marine shelf. The general dense lower section of the regressive lime was deposited in a low energy, open marine environment. As water depth decreased, a high energy environment was introduced in which the productive upper section was laid down. As the sea regressed further, porosity was enhanced by fresh water diagenesis, bioturbation, dolomitization, and in some areas subaerial exposure. Local bathymetric highs and minor fluctuations in water depth controlled the development of this secondary porosity. |
| Formation Lithology: | Kansas City "H" Zone: Cream to light gray, fine crystalline limestone; fossiliferous & oolitic; vugular porosity. Kansas "I" Zone: White to cream fine crystalline limestone; fossiliferous and oolitic; vugular and interfossiliferous porosity. Kansas City "J" Zone: White to cream fine crystalline limestone; fossiliferous; vugular and interfossiliferous porosity. Kansas City "K" Zone: Light gray dolomitic limestone to cream medium crystalline dolomite; sucrosic in part; oolicastic porosity. |
