Abstract: A wireline apparatus is for moving a tool into or out of a well. The apparatus is configured for forming a pressure vessel in combination with at least a portion of the well. The apparatus has: a first compartment for forming part of the pressure vessel; a hoisting means, the hoisting means being placed inside the first compartment; a wireline connected to the hoisting means; a second compartment arranged inside the first compartment; an electrical motor for driving the hoisting means, the electrical motor placed inside the second compartment; and a drive shaft for connecting the motor to the hoisting means, the drive shaft extending from the motor to the hoisting means through a wall separating the first compartment and second compartment. A method is for moving the tool in the well.

Abstract: A method is for suspending flow in a well. The method includes placing a first plug in a production tubular in an upper wellhead section, above a downhole safety valve. The first plug is adapted to fit into the production tubular to form a fluid seal in the production tubular to form a barrier for containing well fluid; equipped with instrumentation for obtaining information by measuring physical characteristics below the plug; and equipped with means for transmitting said obtained information to an operator. There is also described an apparatus for suspending flow in the well.
