Abstract:

Well completions in the United States are predominantly completed using the plug and perforate process.  Following the fracture stimulation treatment, coiled tubing (CT) is utilized to convey a downhole milling assembly to remove these plugs and clean out the wellbore.  As wells continue to extend in lateral length, the use of an extended reach tool (ERT) is commonly used to aid in achieving these depths. 

In order to truly understand the milling process using an ERT, a downhole memory tool was developed.  The memory tool is run in-line with the milling assembly and obtains weight on bit (WoB), torque, pressure, temperature, and vibration at one second sampling rates.  The tool has been run on multiple bottom hole assemblies on both 2 3/8” and 2 5/8” coiled tubing on over 35 jobs accounting for 1500 frac plugs.

The data collected has been compared to surface data providing a detailed view of the overall plug milling operation. Each frac plug manufacturer has a unique torque “signature”, easily identifiable through the analysis. Additionally, the extended reach tools used in the operations provide weight-on-bit while milling at a level that is un-predictable by commercial coiled tubing modeling software.  Comparison of the surface weight gauge with the downhole WoB enable a clearer understanding of the forces provided by the ERT. This data provides an avenue for detailed plug comparisons, better job planning and informed decision on ERT selection.
