Improving the efficiency of reservoir pressure monitoring in low-permeable carbonate reservoirs

Abstract

he modern development of the resource base of the Volga-Ural oil and gas province is characterized by a reduction in the share of highly productive development facilities. The emphasis is shifting towards the operation of low-productivity collectors. Improving the efficiency of managing such assets requires timely monitoring of the energy state of deposits, reasonable selection of geological and technological measures. The approach to monitoring reservoir pressure in this case should differ from the standard, a combination of the most effective research methods is necessary. In conditions of low productivity, methods based on long-term monitoring of reservoir pressure with subsequent data processing using special techniques have proven themselves well. Ultimately, the combination of various methods for monitoring the energy state of low-yielding carbonate reservoirs allows you to individually create an effective research program that allows you to further manage the development. The presented article is devoted to solving these problems. Keywords: carbonate reservoir; permeability; pressure recovery curve; thermomanometric systems; multi-well retrospective test; control piezometric well stock.
