Flow Control Systems

DIC-R Bottom No-Go Non-Ported Landing Nipple is a tubing nipple for use with bottom no-go locking devices only. These Landing Nipples are typically located at the bottom of the tubing string as the last profile, with only a slickline re-entry guide lower in the tubing string.
DIC-R nipple locates, seals, and retains flow control accessories that have a bottom no-go locking device.

DIC-X Landing Nipples are fully selective nipples used to land, lock, and seal X–type locking mandrels with attached flow control devise in the production tubing string.

When installed, the locking tykes in the X–type lock move out into the recess of the nipple, anchoring the lock and situating the lock packing in the polished seal bore section of the nipple. Our Landing Nipples are made from 4140, L-80 low alloy steel, and 9Cr 1Mo Steel.

(Bottom No-Go)
DIC-XN Landing Nipples are non-selective nipples, used to land, Lock and seal XN-type locking mandrels with attached flow control devise in the production tubing string.

The internal profile of DIC-XN Landing Nipples includes a No-Go profile, a locking recess, and a polished/honned seal bore.

DIC-OR Selective Non-Ported Landing Nipple is a tubing nipple for selective locking devices only. These Nipples are designed for heavy-weight, higher-rated pressure tubing. DIC-OR nipple locates, seals, and retains flow control accessories. The accessories are run and retrieved with Slickline.

OR-Landing Nipples are typically located above DIC-ORN Bottom No-Go Landing Nipples.

DIC-ORN Bottom No-Go Non-Ported Landing Nipple is a tubing nipple for use with bottom no-go locking devices only. These are designed for the heaviest weight, higher-rated pressure tubing. ORN nipple locates, seals, and retains flow control accessories with a bottom no-go locking device.

When placing a DIC-ORN Bottom No-Go Landing Nipple in the work string, ensure that the DIC-ORN is the last landing nipple in the completion string.

(Selective)
XA Sliding Sleeve is a communication device with a ported inner sleeve that can be opened or closed using a shifting tool by standard slickline or coiled tubing methods. Equalizing holes in the inner sleeve provides pressure equalization between the tubing and the casing annulus.

The sliding sleeve forms part of the tubing string. The XA Sliding Sleeve is a shift-up-to-open tool.

Selective (Jar DOWN to Open)
XO Sliding Sleeve is a communication device with a ported internal sleeve that can be opened or closed using a shifting tool via standard slickline or coiled tubing methods. Equating holes in the inner sleeve gives pressure equalization between the tubing and casing annulus as the sleeve is opened. The sliding sleeve forms part of the tubing string.

The XO Sliding Sleeve is a shift-down-to-open tool.

Selective - (For standard well environment)
L sliding sleeve is a device used to establish communication, when desired, between the tubing and annulus. L Sliding Sleeve has seal bores above and below the ports and a top No-Go shoulder and locking groove.
