Abstract White Rock field is located in Lane County, Kansas, and occupies parts of 27W and 28W Range on the 17S Township. There has been oil production in this field since 1973, when the first well struck oil in the most successful formation, the Lansing Kansas City. Subsequent producing formations were discovered, which included the Pawnee group as well as the Cherokee Group. Lansing Kansas City is an alternating group of shale and limestone rocks, and traps oil migrating from the Anadarko Basin in. The main trapping mechanism in Lansing Kansas City is a local anticline. As of July 2014, there has been 855,048.04 bbls of oil and no gas produced out of White Rock field. For the past seven years, the field has produced at an average rate of 3578 bbls/year, and is estimated to be depleted by the next 5 to 7 years at current production rates.
Introduction
For the past 100 years, petroleum products have come under great investigation. This rush for the use of these products, and the current dependence of the world, has led to a substantial research for understanding oil and gas production. As for the recent history, little is left up to chance when it comes to producing in a field, and numerous amount of research tools and methods are used to better the results of projects. The purpose of this paper is to show how these methods are used in better understanding White Rock field in Lane County, Kansas.
In order to understand the extensive information behind White Rock field, a two-step process was used. The first was the gathering of information. This part of the process included trips to the KGS library in Lawrence, KS, search of the web, and the use of materials provided in Reservoir, Well Logging, and Geology courses. The information gathered included the well logs and completion cards of drilled wells, relevant equations, laws and theories, as well as background knowledge of the field. The second part of the process included the organization and use of said information. The main program used for organizing data pertaining to the field was Petra, and the data analysis was done with excel spreadsheets. Once the petrophysical and geological configuration of the field was studied, conclusions were made about its current properties as well as its future outlook.
Field Information and Development
White Rock field is in Lane County, located in west central Kansas. It occupies parts of two ranges almost symmetrically on the 17 south township. It has a shape of a whistle, and the exact location is 17S-27W: SW 7, S2 & NW 18, N2 19, and 17S-28W: SE12, S2 & NE 13, N2 24 (KGS,2014). The figure below shows a general picture of where White Rock field is.
White Rock has a field size of 1920 acres. There are 27 total wells, 13 of which are abandoned. As of July 2014, there has been 855,048.04 bbls of oil, and 0 SCF of gas
