Cut & Cap Abandonments: Mobile Waterjet Cutting in Oil and Gas
Updated: Mar 15
Waterjet cutting has revolutionized the oil and gas abandonment process. NuWave's mobile, natural abrasive waterjet cutters have proven themselves more efficient and cost-effective than the traditional torch cutting method.
Our system is faster and safer. With each wellbore taking approximately 30 minutes to cut and cap. Our process saves our clients time and money. Below is an overview of how we provide superior Cut & Cap services to our oil and gas clients throughout North America.
Step 1: Prep Wellhead for Work
Our crews remove the "Christmas Tree" wellhead system from the 14" wellhead connection on site.
Step 2: Insert the Waterjet Cutter
After the removal of the wellhead system, NuWave prepares the subsurface wellhead waterjet cutter and lowers it into the casing bore at a standard depth of 2.5 meters (8 feet) or to the client's preference.
Step 3: Activate Cutting Equipment
The centralizing tool is activated to ensure the cutting head is centered within the casing bore. All hoses are then hooked up to the cutting tool. Pressure is then built up to 42,500 PSI. Once at full pressure, the cutting begins.
Step 4: Begin Cutting the Wellbore
A full steady stream is applied first to penetrate the casing. A rotation of 360º happens, severing the casing.
Step 6: Rig-Out Cutting Equipment from Wellbore
Once cutting has been completed, the subsurface wellhead cutter is rigged out of the wellbore. Using the backhoe loader, the well casing is hoisted from the ground.
Step 7: Cap the Wellbore & Complete Abandonment
The previously prepped "centralizer" with a cap or API plate is lowered into the production casing. The rod is broken off, securing the cap in place, and then the hole is filled. Leaving no trace of the process.
