Improving production in steamed wells with a ring seal packer

Conference ·
OSTI ID:403051
In thermally enhanced cyclic and steam flood wells, production declines as the fluid level in the reservoir drops and the remaining depleted zones connect with wellbore perforations. The depleted intervals act as steam thief zones for cyclic (huff and puff) wells or steam override (break through) zones for steam drive applications. Most cyclic steam and steam drive secondary recovery processes are found in unconsolidated sand reservoirs that generally require slotted liner type completion for sand retention. Slotted liner type completions make zonal isolation a significant challenge. Several methods have been used to completely isolate these zones from the wellbore (i.e., matrix cements, resins, sidetracking liners, etc.) but most require complex workovers and are relatively expensive. The ring seal packer was developed as a far less expensive alternative to these methods while achieving only slightly less than complete isolation. This paper presents the design of the RSP, deployment methods, and successful field production results.
