About Sand Jet Perforating

Sand jet perforating (SJP) is a process that uses high pressure fluid slurry to perforate tubulars and cement within an oil or gas well, and simultaneously extend a cavity into the reservoir. SJP has its origins in the 1960s with many large scale commercial successes in several international venues. While the SJP process was a technical success at that time, it was not an economic success. Few advancements in technology were attempted until the late 1990s. Advances in metallurgy have allowed major re-designs of sand jet perforating tools and jet orifices. These advances coupled with improvements in pump liner design have made SJP more cost effective today. The use of coiled tubing as a conveyance method further allows fluid pressures to be increased, and higher pressure limits make the SJP process even more effective. Newer modular SJP tool designs ensure near limitless re-configuration of coiled tubing conveyed plugs, packers, hold-down tools, perforation, and fracturing tools for simultaneous use during completion and work-over operations.

Applications for Sand Jet Perforating technology include perforation and re-perforation of vertical and horizontal oil and gas wells and perforation and treatment of coal bed methane wells. SJP can also be used in conjunction with other technologies such as fresh water and foam fracturing and for enhanced performance resulting from chemical injection and acidization. Sand Jet Perforating provides an alternative to widely accepted wire-line or tubing conveyed explosive methods used in most fields today. Hundreds of documented successes are available to confirm that SJP increases communication between well bore and reservoir more effectively with less formation damage and is accomplished in fewer round trips in and out of the well bore than more widely used perforating methods. Added benefits are realized as perforating and fracturing can be accomplished nearly simultaneously with a common work string.
