Drilling and Cementing to Isolate Productive Series and High Pressure Zones: A Successful Case History Enables Zonal Isolation in High Pressure Gas Well with Close PPFG Margins in South Caspian Basin
Abstract:The objective of this paper is to share the experience of how 7-5/8" section was drilled, and cased-off to enable the zonal isolation in the depleted VII horizon and high-pressure zone with close PPFG margins by managing high risks of differential sticking and loss of circulation at Bulla gas-condensate reservoir which is one of the most complex high-pressure fields with close PPFG margins in the world.
The Bulla wells are highly complex wells the Caspian region. Before drilling into the reservo… Show more
