Pollnow Field Oil & Gas Data

General Field Information
Produces Oil: Yes Produces Gas: No
Exploration Method:	Seismograph
Drilling Casing Practices:	Most wells were completed naturally through perforations; later, after a decline in production, they were acidized. Required surface casing: Miminum of 200 feet.
Discussion:	A large portion of the productive acreage had been initized by 1959 so that the reservoir could eventually be water flooded. The Pollnow field is a typical example of a thin Kansas City porous bed producing an economical amount of oil when it is developed and operated in a prudent manner.

Summary Production Information
Field Size:	2240 acres
Total Wells:	48
Productive Oil Wells:	21 as of June 2000
Abandoned Wells:	15
Cumulative Oil:	1,294,405.41 bbls as of June 2000

Producing Formation:

Depth Top:	3734 feet
Formation Lithology:	The pay zone is a uniform 4-foot ledge of buff to tan, highly fossiliferous, reef-like limestone. Core samples revealed an abundance of fusilinids in a fine crystalline limestone matrix with vuggy porosity.
Trap Type:	Reservoir is a porous limestone lens with its stratigraphic accumulation limited by a facies change into non-permeable material.
Continuity of Reservoir Rocks:	Due to the absence of a definite water table, the dry holes defining the field are attributed to lack of permeability and porosity rather than loss of section or structure.
