General Field Information | |
| Exploration Method: | Drilled on a Winfield anomaly in the Hugoton gas field |
|---|---|
| Drilling Casing Practices: | The wells drilled before July 1959 were fracture treated with treatments varying from 6,000 gallons plus 6,000 pounds sand to 12,000 gallons plus 12,000 pounds sand. In some cases the fracture treatments were preceded by small acid treatments to clean out the formation. |
| Discussion: | As of July 1959, the average cost of a 4800 foot dry hole was $33,500. The average cost of a completed oil well, including the fracture treatment, was $57,400. |

Producing Formation:MARMATON |
MARMATON (Marmaton Group) |
| Produces Oil: | Yes |
Producing Formation:MORROWAN |
| Depth Top: | 4694 feet |
| Formation Lithology: | Fine grained, sub-rounded, calcareous, friable in part and slightly glauconitic |
| Trap Type: | The stratigraphic Morrow sandstone reservoir was deposited in a saddle of an approximate northeast-southwest Mississippian Trend. The sandstones grade laterally to shale to the east and west. |
| Continuity of Reservoir Rocks: | The northwest and southeast limits of the field have been defined by facies changes in the Morrow section. The northeast and southwest limits of the field have not been defined. |

| Water Production: | Maximum water saturation: 46%; minimum 30% Water specific gravity: 1.155 at 80 degrees F. The Garden City 'D' 1-21, 15-055-00026, in 23S-34W-21, NE SE NW, was completed on February 6, 1957 for 138 BOPD plus a trace of water. In February 1957, the well made 2-9% water, averaging 5%. For the month of May 1959, the well produced 4% water. The resistivity of the water produced was .052 ohms at 100 degrees F. |
