Challenge: Streamline completion of
uncemented, extended-reach heavy oil wells in unconsolidated sandstone, using
equipment suitable for future thermal recovery processes
Solution: Deploy liners using 7-in × 9
5/8-in COLOSSUS UNC uncemented liner hanger system fitted with thermal
elastomers, together with a hydraulic set and release running tool
Results: Reduced liner installation time from
10 days to 1 1/4 days on average per well with zero NPT, saved operator USD
590,000, and enabled achievement of production goals
