SOP for the Removal of
Production X-mass Tree & Installation of Frac Tree
Description: A step-by-step Standard Operating Procedure for safely, efficiently, and in accordance with the industry best practices removing a production X-mass tree and installing a frac tree. It's a necessity for petroleum engineers, well intervention specialists, and field personnel conducting workover and completions operations.
Introduction
Oil and gas line of work, an
expulsion X-mass tree is taken out and a frac tree is introduced in preparation
for a well to be fractured. The purpose of this SOP is to outline a
step-by-step procedure for carrying out the process in a consistent and
reproducible manner, while also addressing safety, efficiency, and regulatory
compliance concerns. When executed correctly, this reduces risk, prevents
downtime and improves production performance.
What you should know about the X-Mass tree and Frac tree
Production X-Mass Tree
Production X-mass Tree A production
X-mass tree is an integral part of producing well. It contains a variety of
valves and fittings that shepherd the flow of hydrocarbons, offering pressure
containment and monitoring features. As time passes and enhanced recovery
methods, such as hydraulic fracturing, are required, the production tree must
be removed and replaced with a frac tree.
Frac Tree
A frac tree is a wellhead assembly
that is specifically designed for high-pressure hydraulic fracturing
applications. It offers multiple access points for stimulation operations and
maintains well integrity through the fracturing process.
PLANNING & SAFETY MEASURES PRIOR TO THE JOB
✔Assessment of Risk & Safety Measures
✔So first do a JSA about this job if
there are moreover hazards.
✔Make sure you have the
certifications and PPE (Personal Protective Equipment) required for all
personnel, such as flame-resistant clothing, gloves, hard hats, safety glasses,
and steel-toed boots.
✔Maintain a no-go zone to keep people
from getting near the wellhead.
✔Confirm emergency response and
verify that fire suppression is provided on site.
✔Verify implemented lockout-tagout
(LOTO) procedures to block well pressure and energy sources.
Equipment & Tools Required
✔Torque tools and hydraulic wrenches
✔Well control equipment (BOP, lubricator)
✔Lubricants and sealing compounds
✔Pipe and fittings rated for high
pressure
✔Gas detectors and safety alarms
How to Remove a Production X-Mass Tree — Step by Step
Step 1: Clean up the X-Mass Tree
removal well
✔Shut in the well and confirm zero
pressure at the wellhead
✔Use a controlled venting system to bleed
off any remaining pressure.
✔Release the production tubing hanger
lock, and ensure that all pressure seals are released.
✔Manage potential pressure surges by
securing the well with a Blowout Preventer (BOP).
✔Use suitable lifting gear to remove
the tree cap safely.
Step 2: Detaching the X-Mass Tree
✔Using a wrench with attention to
controlling residual pressure, Loosen and dismount the production valves
✔Hydraulic wrenches disconnect the
tree from the wellhead flange.
✔Check the flange face for damage or
debris that could impede seal integrity.
✔Lift the production X-mass tree
carefully with a crane and take it to a storage location.
Procedure for Installation of Frac Tree in Stepwise
Step 1: Inspect before you Install
✔Examine the frac tree parts for
defects or signs of wear.
✔Check that all seals, gaskets, and
connections are wellhead compatible.
✔Downhole: Make sure frac tree is
aligned with wellbore.
✔Install the Frac Tree
✔Crane the frac tree over the wellhead.
✔Gently lower the tree and line it up
with the wellhead flange.
Connection: The frac tree must be
bolted in place, then torqued according to the manufacturer's specifications.
✔Install frac valves, and ensure that
ports are sealed to prevent leakage.
Step 3: Pressure Testing & Verification
✔Perform a pressure test to ensure
the frac tree's installed integrity.
✔Use digital gauges to check for any
drops or leaks in pressure.
✔Conduct a thorough check and ensure
compliance with all relevant regulations.
Example: Post Installation Safety
Checks and Documentation
✔Make a final safety walk through on
and make sure all equipment is operational.
✔Depending on the setup, update the
well schematics and maintenance logs with the new frac tree details.
✔Ensure stakeholders such as
engineering teams and regulatory bodies are aware upon the completion of
installation.
✔Open the well for the operations of
hydraulic fracturing.
Industry Compliance & Best Practices
✔Adhere to API (American Petroleum
Institute) for wellhead equipment handling.
✔Follow OSHA (Occupational Safety and
Health Administration) workplace safety guidelines.
✔Conduct periodic training for all
field personnel on frac tree installation and wellhead maintenance.
✔Keep accurate records and reporting
with regulatory agencies.
Conclusion
Production X-mass tree have been detached and frac tree has been mounted for well intervention and stimulation processes. This SOP, if followed by petroleum engineers and field personnel, allows for safe and efficient operation and regulatory compliance. Hydraulic Fracturing and Production Enhancement After the completion, implementing hydraulic fracturing and production enhancement measures leads, on a significantly planned, on quality verified, and tested well.
