Scenario: You are the supervisor for a well maintenance crew operating an HWU. You receive a request to perform a workover on a well that has experienced a significant drop in production. The crew is currently working on another well site located 200 miles away.
Task:
1. Outline the steps you would take to move the HWU to the new well site and prepare it for the workover operation. 2. List the essential equipment and personnel you would need for the workover, considering the information provided about HWUs.
1. Steps to Move the HWU and Prepare for Workover:
a) Communication: Contact the well site to confirm the workover requirements and obtain any necessary permits. b) Logistics: Plan the route to the new well site, considering road conditions and potential delays. Arrange for fuel, transportation, and any necessary permits for the HWU movement. c) Transportation: Carefully load and secure the HWU onto the transport vehicle. Ensure all safety measures are in place. d) Arrival: Transport the HWU to the new site and ensure it is parked safely and securely. e) Setup: Unpack the HWU and prepare it for operation. Connect the necessary power sources, check all equipment for functionality, and perform safety inspections. f) Tooling: Identify the specific tools needed for the workover based on the well's requirements. g) Crew Briefing: Inform the crew about the workover objectives, safety procedures, and any special instructions.
