Common Requirements for All Slickline Jobs (SOP)

SOP FOR COMMON REQUIREMENT IN SLICKLINE OPERATIONS: MAINTAINING SAFETY AND EFFICIENCY

Introduction

Slickline operations are critical to maintaining well integrity, performing diagnostics, and optimizing production in the ever-changing landscape of oil and gas extraction. Following a Standard Operating Procedure( SOP) is critical to the successfully conduct slickline jobs with security in mind. The article covers a comprehensive SOP for common needs in the slickline operations including two main procedures which are intended to facilitate operations as well as reduce the risk.

First Procedure: Basic Safety and Preparation

1. Both Safety and Operations Meetings

WELL OPERATION APPROACH Starting slickline operations with safety and operations meetings sets a tone for the job. Sharing goals and a safety-first mindset by discussing rig-up (RU), testing, procedures, and personnel requirements They also ensure that everyone is aware of possible hazards and their respective roles.

2. BOP Function Test

Ground testing allows function tests for Blowout Preventers (BOPs) to ensure product operation and safety. Since closure takes place in 30 seconds to 2 minutes, it minimizes downtime and elevates operational efficiency. Testing BOPs on a regular basis ensures that they make the right decisions in the event of an emergency and reduce the chances for blowouts.

3. From: Certification of Lubricator Components

It effectively requires lubricator components to be certified that they are reliable and meet industry standards. Welded lubricator fittings shall not be used because they create structural deficiencies and hazards. So, this step also ensures that the equipment used in the operation is safe and fulfills the purpose.

4. Wireline Tool String Components Logging

Keeping accurate records with detailed information about wireline tool string components, such as Length, OD, and fishing neck sizes aids in the planning and execution of an effective job. The documentation aids in debugging and ensures that the correct tools are selected for the task.

5. Equipment Preparedness

Having a full suite of wireline equipment, including contingency tools such as sand bailers, impression blocks, and gauge cutters, equips the team for unforeseen circumstances and builds operational resilience. With training of the slickline equipment inventory, a well-prepared equipment inventory will minimize the risk of delays as well as prevent stoppages during the execution of slickline tasks.

6. Fusible Lockout Cap

More Out the door — Install fusible lockout caps on the Hydraulic Master Valve (HMV), so that accidental closure of the valve does not occur during operations or maintenance, protecting personnel and equipment. This step is essential for avoiding accidental interruptions that could jeopardize safety and operational effectiveness.

7. Standardization of Depth Reporting

If the depth will be reported from the crown valve (CV) or drill rig floor (DF); If a measurement is slick line (SL) or electric line (EL); Make depth reporting-standardized. Surveying is responsible to confirm well control and to accurately place tools on target.

2nd Procedure: Execute the slickline operation

1. Packing with Bleeders and Packer with Gauge Cutter

The second procedure, slickline specific, begins with rigging up the BOPs and lubricator with a gauge cutter. Correct rigging up prepares the well for intervention and minimizes the risk associated with the operations.

2. Valve Operations

Opening these components helps to equalize pressures and allows for fluid to flow, allowing the well to be prepared for slickline tool deployment. Such actions provides a controlled environment for run in hole (RIH) operations.

3. Lubricator Pressure Testing

The lubricator need to be pressure tested to 7500 psig with a water-glycol mixture to verify its integrity under operation condition, as well as to avoid equipment failure. This test is critical to ensure that the lubricator can handle the pressure that it will see while operating.

4. Pressure Bleeding and Valve Management

Well control is established by bleeding the pressure from the tree to Shut-In Wellhead Pressure (SIWHP) and closing the valves. In controlled pressure management, the risk of releasing an open valve under pressure is reduced.

5. MLMV and HMV Opening

The opening of the Master Line Master Valve (MLMV) & HMV initiates the deployment stage of the slickline tool, which is one of the critical parts of the operation. Valves operate optimally to allow the tool to enter the wellbore smoothly.

6. Running in Hole (RIH) with Gauge Cutter

RIH with gauge cutter for cleaning of the wellbore for subsequent operations. This measure avoids obstructions, increasing the efficiency of any future intervention.

7. Pull Test and Drifting

Performing a pull test every 3,000 feet and drifting the well to Planned Bottomhole Total Depth (PBTD) prepares for future operations and can ascertain if there is an obstruction that needs to be cleared prior to operations. This ensures that the wellbore is clear and tools can be deployed without issues.

8. Tool Location Check and Valve Shutdown

Thus, confirming the position of the tool inside the lubricator and closing the valve at the top of the lubricator after sighting the tool ensures well control and safety. Correct positioning of the tool also minimizes misruns and improves precise machining of parts.

9. Tree Flushing and Pressure Bleeding

This process aids in removing any potential contaminants through bleeding pressure from the lubricator and flushing the tree with a water-glycol mixture, improving equipment integrity and safety. This keeps wellhead components clean and functional.

10. Well Test Separations and Final Valve Closure and Lubricator Rig Down

The slickline operation concludes with closing the CV and B/D 'Lo-torque' valve and rigging down the wireline lubricator, as the well is prepared for the next operation. Description of Proper Rig-Down of Equipment Ensures Moving Forward There Are No Future Issues Having the right rig-down procedures helps ensure equipment longevity and avoids operational issues in the future

11. Tree Valve Binding in Production

The completion of safely locking the remaining tree valves of the production, provides well integrity, safety, environmental and operational assurance. During holes and re-run after changing the valve, it is an important procedure to avoid carrying out unwanted flow and maintain well control.

Conclusion

With this detailed SOP for common requirements in slickline operations, oil and gas operators can improve safety, streamline operations, and optimize production.
