CASE STUDY: Insulating Packer Fluid Offers Cost Effective Alternative in Deepwater OperationsLocation: Offshore Louisiana
Preventing well failure caused by annular pressure buildup in Gulf of Mexico deepwater wells. Find a less-expensive and efficient insulation system that would prevent heat transfer and allow for increased
flow rates.
N-SOLATE® packer fluid was custom-engineered specific to well conditions, formulated for a delayed cross-linking until placed in the wellbore; at which point full gelation of the system occurred
In each well, 10 lb/gal packer fluid was blended on the rig site and pumped into the production annuli. Maximum flow-production temperatures for the wells were 210º F (99º C). The cross-linking occurred before reaching this temperature, activating the insulating gel structure.
Using the high performance packer fluid, It took 12 hours less rig time at a depth of nearly 22,000 ft than it would have to achieve a lesser depth of 10,000 ft with vacuum insulated tubing
Nearly $2 million in cost savings were realized over using the traditional vacuum insulated tubing system

CASE STUDY: Innovative Use of N-SOLATE® Packer Fluid in Gulf of Mexico
Lost circulation
High ECD
Because of extremely cold sea floor temperatures, the synthetic-based fluid was becoming excessively thick when cooling off in the riser, requiring greater pump pressure to move
N-SOLATE 600 packer fluid was used in the riser wall annulus to keep the heat from the synthetic-based mud (SBM) in the main annulus from being lost to cold sea floor temperatures
Once the N-SOLATE 600 packer fluid was in place, further lost circulation was not experienced
Equivalent circulating density (ECD) was drastically reduced
Higher circulation rate and faster drilling rates achieved
Drilling fluid returned to surface 20 degrees warmer compared to wells without the insulating effects of N-SOLATE fluid
Less stress on the wellbore throughout the entire operation
Major reduction in drilling time and reduction of fluid costs
