Why Would I Need a SuperSlim™ Sand Jetting Tool?
What applications are there for a sand jet perforating or cutting tool that is smaller than 2" OD?
We are glad you asked! There are many different types of scenarios where a sand jetting tool smaller than 2" OD (a SuperSlim™ tool) can provide a very cost effective solution. Our preferred service providers often find opportunities for SuperSlim™ tools in production tubing that might need to be punched (tubing only), perforated (tubing and casing or tubing/casing/formation), or completely severed.
Dajan S.r.l., a preferred service provider for TD Tools, recently completed a job with both perforating and cutting using our patented SuperSlim™ tool. The plug and abandonment job in Italy required perforating two strings of 2-3/8" tubing, cutting and retrieving the tubing, and cutting and retrieving 7" casing. The entire job was performed as a rigless operation.
Rigless Well Plug and Abandonment In Italy by Dajan
The plug and abandonment job consisted of several components. Production tubing and casing perforations for each of the two strings was performed with a SuperSlim sand jet perforator (SJP) tool on 1-1/2" jointed tubing. Perforations were placed at 2,300 feet and 500 feet through the tubing and 7" casing to deploy cement inside all of the annular spaces. Next, each 2-3/8" production tubing was severed using the same SuperSlim used to make the perforations. The bottomhole assembly (BHA) and tubing string were rotated from the surface utilizing a power swivel. As this was a dual completion well, the first production tubing was cut and removed and then the second tubing was cut and removed.
Severed 2-3/8" Tubing from P&A Job
After the tubing was removed, the 7" casing was severed using a MegaPerf tool. 2-3/8" production tubing was used as the workstring for this phase of the job. The MegaPerf was also rotated using the power swivel to make the cut. Sand jetting (also known as abrasive jetting) creates a smooth cut that is easy to fish or wash over as seen in the pictures from this job.
7" Casing Cut
In addition to plug and abandonment work, the SuperSlim tools can also be used to pass through restrictions in the tubing string and perforate. Tool OD's range from 1-3/8" to 1.875" typically running two to three jets on the tool. The perforations can be through a single casing, cement, and into the formation or though multiple casings, cement, and into the formation.
Pumping abrasive slurry through the tool can allow cutting energy to be conveyed continually through the tool to achieve the goal of the project, whether that is severing a pipe or eroding holes through multiple pipes. Conventional explosive perforators are limited to the amount of explosive charge that can be placed into the tool for a one-time detonation event. The ability to perform these jobs rigless provided significant cost savings over having a rig on location to add to the safety benefit of eliminating explosives.

e recently had the opportunity to meet in person with Dr. Mathew Samuel, CEO of Atomix Chemicals Company. Atomix manufactures an abrasive material designed for use in abrasive hard scale removal and also abrasive jet perforating and cutting. TD Tools was able to participate with Atomix in a function test conducted in Saudi Arabia in March that examined abrasive descaling utilizing the Atomix CarboSolve. ALG provided the RBJet rotating tool for the test and Atomix provided the CarboSolve material. A section of 7" casing was cleaned using the CarboSolve and the RBJet tool. Operating parameters were up to 2 bpm abrasive slurry and up to 1200 scf/minute of nitrogen.
