The Hugoton Anadarko Area has seen the growth of several large casinghead systems during the past few years. Since pipe line companies historically look for the long term sources of supply, analyses of various casinghead gas gathering systems have been made. Gas supply from these systems can most generally be depended upon for long periods of time. The system should be located in a developing gas and oil area and should be available early in the development life.
The casinghead reserves per well can be expected to be small and, in order to maintain a break-even position, 20 - 25% new wells must be connected each year. In the successful operation of a casinghead system, the company must be aggressive. The drilling slump has not appreciably effected those systems whose managements are active.
The Hugoton Anadarko Area has 2.5 Tcf of proved remaining recoverable casinghead gas reserves at January 1, 1970.
The Hugoton Anadarko Area is located on the map shown on Page 5. The proved remaining recoverable natural gas reserves for the total Hugoton Anadarko Area has been steadily declining since 1959 at an average rate of 1.25 Tcf/year, see Fig. 14. However, during this time the casinghead gas reserves continued to increase, peaking in 1965 at a remaining recoverable reserve of 3.6 Tcf of gas. When this trend was noticed in the early 1960's, an evaluation was set in motion to determine some of the more desirable characteristics of a casinghead gas gathering system and if they could be depended upon for long term supplies of gas.
In analyzing this question, two large problems are encountered immediately. The problems are encountered immediately. The first problem is that all of the casinghead systems are very complex. The second problem encountered is that very little problem encountered is that very little information concerning these systems is available for analysis.
