“Mongoose” systems for HFT – collaboration technology with “ЕВС” LLC

Technology with the “MultiStage Unlimited” assembly serves to separate the intervals for the fracturing. The assembly is lowered by means of coiled tubing. Either there is a FHF on coiled tubing, followed by “Mongoose” or sliding sleeves (“MultiStage Unlimited”) installation, or two technologies are used simultaneously. Used for fracturing treatment in few intervals per one coil tubing round-trip operation. The ability to conduct operations in vertical or horizontal wells in production casing strings without special equipment. Hydraulic fracturing is performed in previously perforated intervals or after hydrosand-blasting perforation just before the fracturing. Abrasive medium hydroperforation at the designated fracturing points. Interval perforation – about 45 minutes. Interval sampling is performed by the casing collar locator. The productive horizon below the perforation zone is insulated by a multi-purpose bridge plug.
