This paper presents the results of the implementation of compression to increase the deliverability of Clinton sandstone natural gas wells by lowering the effective line pressure against which the wells must produce. Graphs in this paper display the historical producing rates with time, both before the compression was implemented and after the compression was implemented.
The wells studied are producing natural gas through the tubing, through valves that open and close intermittently with duration of flow time and shut-in time controlled by clocks. Some of the wells have controls located at the wellhead and some are controlled at the separator.
Comparisons are made between estimated reserves that would have been produced and accompanying economics without compression versus estimated reserves to be produced and accompanying economics with compression. The estimated incremental reserves and revenue are compared to the initial cost to install the compression.
Duration of intermittent flow times and shut-in times and the accompanying pressures before compression are compared to those subsequent to implementation of compression.
Comments are included concerning the use of the "decline curve" to estimate natural gas reserves.
