General Field Information | |
| Geologic Province: | Sedgwick Basin |
|---|---|
| Exploration Method: | Subsurface Geology |
| Surface Formation: | Kansas Alluvium, Pleistocene |
| Oldest Formation Penetrated: | Arbuckle, Ordovician |
| Drilling Casing Practices: | Move in and rig up rotary tools. Drill 12 1/4" hole to approximately 250' using water and Bentonite gel-based mud. Circulation can be lost while drilling surface hole and severe wash outs can occur. Some operators have set 20' conductor pipe at 30' to prevent this problem. Run a minimum of 200' of 8 5/8" surface casing using 175 sacks of cement to insure circulation back to the surface. Wait eight hours for cement to dry. Drill 7 7/8" hole to total depth using chemical gel mud. Run 5 1/2" production casing to total depth and cement with sufficient cement to cover future perforations by 100'. Perforate entire Hertha Limestone porosity zone with 2 shots per foot. Normally a small acid job is performed to clean up perforations and the area surrounding the well bore. Swab well back to clean up and to determine amount of fluid to be pumped. Put well on pump and begin production. |
| Electric Logging Practices: | Gamma-Guard Sidewall Neutron log is run from total depth to the top of the Chase Group Limestones (approx 1300'). Compensated Density log is run over bottom 2000' of borehole. |
