This paper reflects the experience of applying modern technologies to prevent annualr gas migration, crossflows and pressures (ACP), well integrity assurance during the gas and gas condensate wells construction in South Tambeyskoye field. South-Tambeyskoye gas condensate field is the largest in Western Siberia and the Arctic North of the Russian Federation. The development of this field is carried out by the JSC "Yamal LNG" (PSC "NOVATEK") - one of the worlds leading gas and gas condensate exploration & production companies with the participation of Total and CNPC. Proved and probable reserves of the field according to the international classification PRMS are estimated at 926 billion cubic meters of gas and 30 million tons of liquid hydrocarbons. At the South Tambeyskoye field, several field trial works (FTW) were carried out to prevent ACP on 4 wells: –3 production wells on Valanzhinsky deposits with reservoir pressures up to 350 atm.–1 production well on Jurassic deposits with reservoir pressures up to 820 atm. Technology effectiveness comparison to standard methods has been conducted based on field trial results. Based on objectives achieved using modern technology, field trial works considered succesfull. |
