Abstract: A method for performing operations in a well comprises sensing a condition at, adjacent, or within a wellhead arrangement located at an opening of the well and performing a safety procedure in response to the sensed condition to improve the safety of the well operations. The method may comprise sensing the condition when a tool is located at, adjacent to, or within the wellhead arrangement. The sensed condition may be associated with a status of the tool. The sensed condition may be associated with an emission, field or signal transmitted to and/or from the tool, extending to and/or from the tool, and/or coupled to and/or from the tool. Performing the safety procedure may comprise controlling a position or status of the tool or controlling an environment at, adjacent to, or within the wellhead arrangement.

Abstract: An electrical wireline conveyed baling system for removing large volumes of liquids from a well borehole with a single trip of a bailer tool string. The system also utilizes one or more blow out preventers thereby allowing wireline bailing operations to be carried out while controlling well pressure. A bailer tool string that is conveyed by the wireline comprises a tool head containing a pump, at least one carrier section, and a no-return valve. Once deployed in the borehole, a first signal transmitted via the wireline from the surface activates the pump thereby reducing pressure within the carrier section. A second signal transmitted via the wireline from the surface opens the no-return valve thereby allowing liquid to flow from the borehole into the carrier section. The bailer tool string containing liquid is subsequently retrieved via the wireline thereby removing liquid from the borehole.
