Flow Control

Model ST-2 On-Off Tool is a left-hand release, tubing disconnect device with an internal lock profile for securing flow control equipment.

The “SX” Nipple offers an expanded versatility to downhole selection. Any desired number of “SX” Nipple can be placed in the production string, thereby offering an unlimited number of positions for setting and locking surface control devices.

The “SF” Nipple is a top NO-GO or selective nipple which provides for the location of various wireline flow control devices in the production string. The “SR” Nipple is a bottom NO-GO seating nipple which allows for location of various flow control devices in the production string. “SR” Nipple can be used in the above applications and has restricted I.D .

sliding sleeve is a downhole flow control device mounted in the production tubing. It effectively controls the flow between the tubing and the casing annuals by means of internal sleeve that is opened and closed by standard wireline methods.

Shield circulating sliding sleeve is a downhole flow control valve that can be installed in the production string to provide communication between tubing and casing annulus. These sleeves are economical, versatile option with high availability. SDD-NE Uses Non-elastomeric seals.

The Model SFWG Bypass Blanking Plug is a Top NO-GO wireline retrievable tubing plug, which can be landing in the matched “SF” Landing Nipple. It is designed with a Removable Mandrel for equalizing pressures. The Removable Mandrel is held in the Bypass position by the running tool, to allow fluid Bypass when landing in the seating nipple. When the plug is locked into the desired Seating Nipple, the Removable Mandrel is shifted and locked to close the Bypass Ports. To equalize, a standard wireline pulling tool latches on to and retrieves the Removable Mandrel. After the pressures have been equalized through the Bypass Ports, the plug may be retrieved with a standard pulling tool and proper probe.

The Model SFG Bypass Blanking Plug is a selectively wireline retrievable tubing plug that is designed with a removable mandrel for equalizing pressures. It can be landing in the matched “SF” Landing Nipple. The removable mandrel is held in the bypass position by the running tool, to allow fluid bypass when running through several of the same size nipples. When the plug is locked into the desired seating nipple, the removable mandrel is shifted and locked to close the bypass ports. To equalize, a standard wireline pulling tool latches onto and retrieves the removable mandrel. After the pressures have been equalized through the bypass ports, the plug may be retrieved with a standard pulling tool and proper probe.

The Model SD-2 Shifting Tool is a wireline operated tool used to open and close the Model “SL” Circulating Sleeve. Any number of sleeves, of the same size, in a single tubing string can be shifted in any combination or in any sequence.

The Model “SB” Shifting Tool is a wireline operated tool used to open and close the circulating sleeve. The Model “SBS” Shifting Tool has selective keys, which require you to shear the pin in the shifting tool before releasing. After the tool is released, it will not engage any more sleeves. The model “SBP” Shifting Tool has positive keys, which can be self-release from the sleeve after shifting. After the tool is released, they also can engage sleeve traveled in the hole.
