Keywords: bottomhole pressure, low-permeable reservoirs, productivity index, indicator diagrams
Annotation:
The article analyzes the reservoir characteristics of the Tyumen suite reservoirs. The decrease of bottomhole pressure below saturation pressure in groups of wells was assessed. Indicator diagrams were constructed using various methods and compared with the actual results. Based on the results of the analysis, the bottomhole pressure reduction limit relative to saturation pressure was selected.
