The equipment is simple, reliable and cost effective to the client. Operated from surface using internal tubing pressure, they bring real time and cost savings, and are suited to vertical as well as extended reach development and horizontal wells. On chrome and plastic coated tubular s, these tools help prevent scouring of the tubing walls which in turn lowers the risk of long term problems during the life of the well. OCRE tools allow great flexibility when it comes to completing a well, in that they can be run independently or combined depending on the level of non-intervention the client requires on a particular well. The Full Flow Gun System is designed to perforate long intervals in a single under-balanced run.
Perforation can be continuous, or selective zonal isolation can be achieved.
The FFGS operates under the same principles and in the same environments as TCP guns but, once fired, a full bore conduit is left which permits well hydrocarbons to flow, or logging and well servicing equipment to pass through. Non-intervention reduces overall completion times and accelerates production thus optimising cashflow . No need for rat-hole in vertical wells, so significant savings on drilling. A mechanical disc valve, hydraulically operated from surface using internal tubing pressure. The FBIV is a one shot disc valve run in the closed position capable of holding pressure from above and below.
