Field Testing of Low Temperature Deployment of Bismuth Alloy for GHG Emissions Reduction and Well Casing Abandonment

Solution developer

Seal Well Inc.

Project description

Our proposed project is field testing using Seal Well’s proprietary tools and procedures for measurement and repair of GHG emissions from at least five wells in western Canada using a bismuth-based metal alloy as a sealant. Seal Well’s process uses electrical heating to melt the alloy in situ at a low temperature that avoids extremely high temperatures and the resulting possible plug damage when using processes which rely on highly exothermic chemical reactions as a heat source.

Seal Well’s alloy deployment tools include real time monitoring of downhole temperature and pressure to control with precision the progress of the plugging procedure. Careful attention and effort will be applied to the measurement of GHG emissions before and after the repair procedure, location of the geologic source of the emissions, and identification of strata within the target wells that have the most favorable characteristics to act as an impermeable cap rock to contain the emissions once the bismuth alloy is set.

Support requested

The support that we require is the willingness for one or more well operators to provide suitable wells for our field test operations and to pay for out of pocket costs associated of Seal Well’s field operations and those of wireline and other field services contractors directly involved in necessary support.
