Plugging and Abandonment
EIGHT INTERCEPTOR WELLS HAVE ALREADY BEEN DESIGNED AND BUILT BY SYNGULAR SOLUTIONS FOR THE PERMANENT ABANDONMENT OF HIGHLY COMPLEX WELLS, WITH ABSOLUTE SUCCESS.
Interception Wells for P&A Operations
Interceptor wells are generally used as relief wells to combat blowouts. However, in the case of P&A operations on old wells, whose liners are severely damaged, whether due to tectonic effects or the action of time and operating conditions, it becomes impossible to access the bottom of the well.
Syngular Solutions has a strong presence in the decommissioning of highly complex wells, using interceptor wells to reach the deepest parts of the well. In this way, it is possible to perform bottom plugs and ensure total isolation of the producing zone, guaranteeing operational and environmental safety.
Plugging problem: damaged cased-well
A very damaged cased-well had a total collapse in the casing and the operator had trouble to plug and abandon the well by conventional methods.
Plugging problem: highly damaged well
A highly damaged well, with no access to the bottom, should be plugged and permanently abandoned.
Plugging problem: without access to the bottom
A provisionally closed well, without access to the bottom, had a total collapse that prevented the column from descending to the bottom.
Plugging problem: Reservoir with total fluid loss
closed well, with the casing highly damaged, with no access to the bottom.Reservoir with total fluid loss.Tubing end was close to the bottom of the well.
Plugging problem: fishing
A provisionally closed well, with total casing ruptures, with no work string access to the bottom. There was a 41/2” fish on the well bottom.
