Energized swabbing device for a slickline based well initiation service tool

A system for initiating natural flow in a well, the system comprising:

• a bottom hole assembly (BHA) disposed in a production tubing of the well, the BHA comprising:
• a rope socket coupled to a foam assembly, the foam assembly comprising:
• the foaming assembly is configured to release a foaming chemical to form a foam;
• at least one chemical canister;
• and
• a check valve unit coupled to the at least one chemical canister, wherein the check valve unit comprises a plurality of foam nozzles;
• and
• a swab assembly coupled to the foam assembly, wherein the swab assembly comprises a swab mandrel and a plurality of swab cups;
• wherein the at least one chemical canister comprises a second chemical canister coupled between a first chemical canister and the swab assembly;
• wherein the BHA is configured to displace a workover fluid and reduce hydrostatic pressure in the production tubing with a combined generation of the foam from the foam assembly and well swabbing with the swab assembly;
• and
• a slickline unit coupled to the rope socket of the BHA.

A method for initiating natural flow in a well, the method comprising:

• conveying a bottom hole assembly (BHA) on a slickline to a first depth into a production tubing, wherein the production tubing comprises a static fluid, the BHA comprising:
• a foam assembly comprising a check valve unit coupled to a chemical canister, wherein the check valve unit comprises a plurality of nozzles;
• and
• a swab assembly coupled after the foam assembly, wherein the swab assembly comprises a swab mandrel and a plurality of swab cups,
• holding the BHA stationary in the static fluid;
• releasing a foaming chemical from the chemical canister to the production tubing via the check valve unit;
• activating the foaming chemical to form a foam;
• opening a well flowline;
• and
• swabbing at least a portion of the production tubing with the swab assembly of the BHA by at least partially removing the BHA from the production tubing.
