Can I Inject Treatment Chemicals with SJP?
One of the several unique opportunities provided by sand jet perforating (SJP) is access to the perforation tunnel immediately after the tunnel is created. Chemicals, like hydrochloric acid, can be pumped under pressure directly into the perforation tunnel to enhance the treatment process. Several of our customers have taken advantage of this access to the reservoir formation to inject treatment chemicals into the perforation tunnels.
​
Traditional Explosive Perforation Tunnel Versus Sand Jet Tunnel
​
The difference in sand jet perforation tunnels and explosive perforation tunnels lends itself to more effective chemical injection for the SJP tunnel. The SJP tunnel is eroded at lower temperature and pressure than the explosive perforation tunnel with the reservoir material circulated into the wellbore and up to the surface. Explosives simply pack the reservoir material into the tunnel while it forces its way into the reservoir. The larger diameter SJP tunnel provides more surface area for contact with the treatment chemicals. Spotting acid or other chemicals directly into the perforation tunnels can also reduce the total amount of acid required for the treatment. Chemicals can be injected under pressure, up to 10,000 psi of differential pressure at the tool. A choke can also be used to create annular pressure to help push the treatment chemical out into the formation.
Sand Jet Stream Perforating a Casing
Our sand jet perforating tools have been used as dedicated acidizing or chemical treatment tools in the U.S., South America, and the Middle East. Different jet sizes can be used to achieve the desired flow and pressure rate through the tool and tubing string.
Come Join Us to Learn More About Offshore Slimhole Perforating
The Deepwater Technical Symposium will be held at the Hilton Riverside in New Orleans, Louisiana on August 15th and 16th. This is the 27th year for the conference which is supported by the American Association of Drilling Engineers (AADE), New Orleans Geological Society (NOGS), and the Society of Petroleum Engineers (SPE).
TD Tools has joined with Accu-Line Well Services to author a paper- "Case Study of a Rigless Intervention for the Completion of an Offshore Multi-String Producing Well Using Slimhole Sand Jet Perforating" as a part of the Completions and Intervention Technology session on August the 16th.
