Gas Production Management Options
The primary objective of this study is to extend an oil production plateau period through gas management when the production is limited by the gas handling capacity. Once gas break-through occurs, we would like to know how we should operate to minimize gas production; how effective existing methods are; how we could delay the break-through time. There are a number of options including rate cutback, completion shut-off, well cycling and drilling infills. Effectiveness of those methods may vary depending on reservoir types. This study evaluates relative effectiveness of a number of methods for an existing reservoir using 3 numerical models and field examples.
