A corrosion coupon anchoring system for positively positioning a corrosion monitoring coupon in the production flowpath downhole in a producing well. Preferably cylindrical...

2022年12月20日 · Gas Lift Injection. Injection through a gas lift mandrel. The inhibitor is generally atomized into the gas that is utilized for gas lift. The inhibitor then travels through the annulus and enters the tubing string at the point of the mandrel (Fig. 41). Treater Strings.

A corrosion coupon anchoring system for positively positioning a corrosion monitoring coupon in the production flowpath downhole in a producing well. Preferably cylindrical coupons are held firmly within a cylindrical housing suspended out of contact with any other metallic surface.

The CCI-1 valve is used for downhole injection of corrosion inhibitors and various chemicals to treat, intermittently or continuously, harmful deposits and corrosion in the tubing or around downhole tools.

2017年1月1日 · Downhole corrosion coupons or probes are offered by corrosion-monitoring companies, but these require wireline access to retrieve and usually special fittings downhole. Furthermore, because corrosion may vary at different depths in the well, downhole monitoring is best achieved by multiple locations up the string, which increases the cost and ...

Deliver targeted production enhancement in the wellbore. Whether you need to reduce hydrostatic pressure and increase production with gas lift, to lower viscosity with steamflooding, to displace residual oil with waterflooding, or to deliver production-enhancing chemicals, our downhole injection systems excel.

SAZ Orion GM Conventional Gas Lift Mandrels are available in various tubing sizes, end connections and metallurgy to match the tubing and offer full drift. It is designed to receive 1.0” and 1.5” diameter conventional gas lift valves and conventional check valves.

This patent describes an apparatus for anchoring at least one tubular corrosion coupon at a preselected location downhole in a well that is producing a flow stream of well fluids in a section of cylindrical tubing string that is lacking a side pocket mandrel.

Preferably cylindri-cal coupons are held firmly within a cylindrical housing suspended out of contact with any other metallic surface. An adaptor threadingly engages the cylindrical housing to a...

The BLAZE treated mandrels (lugs and mandrel bodies) showed ZERO corrosion-erosion. Following the inspection, the operator chose to rerun the BLAZE mandrels downhole. Given the performance achieved in this challenging well, the operator ordered an additional 54 BLAZE mandrels for installation on the bottom 6 valves in their next 9 well pad.
