Abstract
A method of plugging a well extending into a formation to facilitate temporary or permanent abandonment of the well. The method includes conveying a plug placement and verification tool (PPVT) through the well, to a plug formation location, the PPVT including a stinger for delivering a plugging material into the well, an expandable packer disposed at one end of the stinger and a pressure sensor disposed below the expandable packer, and operating the expandable packer to form a seal in the well above the pressure sensor. The method further includes delivering a plugging material from the stinger into a region of the well above the expandable packer, thereby forming a plug in the well, and thereafter creating a pressure change above the plug and verifying the integrity of the plug using the pressure sensor.
