Due to their material construction, elastomer and cement plugs can deteriorate over time, particularly in corrosive environments. Conventional bridge well plugs also have very small expansion ratios that limit their application. And while inflatable packers have high expansion ratios, they lack the differential pressure capabilities required for many oil well abandonments, and cannot provide a gas-tight seal.
Reducing the corporate liability and potential environmental impact of abandoning decommissioned wells demands that fluids are sealed securely and reliably for generations to come.
BiSN has developed more effective well abandonment & plugging solutions for P&A programs with our patented BiSN wel-lok™ technology. Our alloys offer higher expansion ratios than conventional bridge plugs and higher differential pressure ratings than inflatable packers, forming a V0-rated, gas-tight seal that cement cannot provide.
Available in a number of unique toolstring configurations to suit your requirements, the proven BiSN technology behind them is the same.
Cement pumping and placement of conventional balanced plugs is especially challenging in wells with multiple casing strings. And due to cement’s physical limitations as a barrier material, it cannot deliver the long-term gas-tight seal required by today’s operators, or for permanent well abandonment.
