With average flow rates of 2.5 bbl/min, the TT-HSRT worked flawlessly in combination with the CTT Oscillator
Overview
Run Date: November 24, 2021
Tool Service Company: Envision Downhole
Location: Scurry County, Texas
Onshore/Offshore: Onshore
Well Type: New Drill: Horizontal
Product: Toucan Tornado 2.87″ Thru-Tubing HSRT: Hi-Speed Reaming Tool
Objective
Clean out the wellbore for toe-prep prior to completion and stimulation.
Results
The Senior Consultant utilized the Toucan Tornado 2.87” Thru-Tubing HSRT on this Permian Basin well to successfully clean out the wellbore prior to completion on 2-3/8” coil.
For this job, the Thru-Tubing HSRT was dressed with a used Varel 4-7/8” Slip Stream Bit. While using Pipe-On-Pipe chemical lubricant on the way in the wellbore the pump rate was maintained at a low ½ bbl/min. At the kick-off point, the pump rate was increased to 2.5 bbl/min while the coil speed was reduced until through the curve when the pump rate was held steady at 2.5 bbl/min while increasing coil speed.
The Float Collar was tagged three times, then a sweep was pumped at 2.5 bbl/min. With average flow rates of 2.5 bbl/min, the CTT Oscillator tool used was operating at ~30 Hz. The TT-HSRT worked flawlessly in combination with the Oscillator tool and an oversize 4-3/4” bit.

Bottom Hole Assembly
3 1/4” Slip-type coil connector
2 7/8” Dual back pressure valve
2 7/8” CTT Bi-directional H/H Jar
2 7/8” Hyd. TJ Disconnect – 0.875” ball seat
2 7/8” CTT Oscillator
2 7/8” Toucan Tornado Thru-Tubing HSRT

4 3/4” Varel Slip Stream (used bit)
BHA appearance: All tools looked good upon retrieval.
Total bbl pumped through BHA: 746bbl
Operational Notes
Convenience utilizing the InFocus 2.87” Thru-Tubing HSRT on location is important to note – the BHA is made up without getting on the man-lift as the Thru-Tubing HSRT is only 2.3 feet long resulting in the total BHA length of a little over 16 feet. This shorter length of the BHA is an advantage handling tools on location.
Run Details
In vertical: Coil speed 80 rolling pumps @ 1/2bbl min.
At KOP: Decreased speed to 40 increased pump to 2.5bbl/min (2600psi) – started POP (Pipe-On-Pipe) 1/8 per 10
At landing point: Increased speed to 60 – pumps still @ 2.5bbl/min (2600psi)
Tagged float collar: @ 14,490’ (tagged 3 time with no change) there was =/- 100psi Differential
Pump Sweep: 2.5bbl/min.
POOH: maintained 60 on speed and 2.5 bbl/min (2600psi) until reaching curve
Cut POP
Through Curve: Coil speed 40 and 2.5bbl/min. (2600 psi)
Back in Vertical: Coil Speed 80 and rolling pumps to 3000’ then shut down pump to bump up
