Coiled Tubing or Jointed Pipe, Which is Better?

 Many of our customers are surprised to find out that approximately 50% of our tools are run on coiled tubing and 50% on jointed tubing. Determining which workstring is best for your application depends on a few different variables:

  • Availability- Depending on where your well is, some workstrings are more readily accessible than others.

  • Cost- Do the well conditions dictate a particular type of workstring? If the the perforating location is 22,000 feet deep, then probably. Otherwise it might be a good idea to look at the costs of different options.

  • Flow- Pipe size is a very important consideration for sand jet perforating. Pressure loss due to the fluid friction is the primary limiting factor of the number of jets that can be run in a SJP tool. We use a model to estimate frictional fluid loss and base the number of jets that we run in a tool on the acceptable pump pressure.

Example of a Sand Jet Perforator with Six Jet Locations on 2-3/8" Production Tubing

The chart above estimates frictional fluid loss (pressure drop) for a sand jet perforator with 6 jets using a 2-3/8" production tubing workstring for perforations at a depth of 10,000 feet. There are generally tradeoffs to evaluate for each workstring type. In this scenario, there is very little pressure drop for the estimated 2.68 barrels/minute flow required for this tool, however it will take longer to run in the well and will require a workover rig as opposed to a coiled tubing unit. In some parts of the world, running the sand jet perforator on drill pipe makes sense due to its availability, cost, and low pressure drop. A similar well type offshore might choose to use coiled tubing with fewer jets on the tool and perform the job rigless due to the high cost of workover rigs offshore.
