FLOW CONTROL TOOLS

OVERVIEW

Gulfwell’s Flow Control Tools can be used in the wellbore to

Regulate flow rate: To control the flow rate of fluids in the well, ensuring that the production rate is optimized while avoiding damage to the wellbore and reservoir.

Measure flow rate: To measure the flow rate of fluids in the well, providing critical data for reservoir management, production optimization, and well testing.

Control pressure: To regulate the pressure in the well, preventing overpressure or underpressure conditions that can damage the wellbore or reservoir.

Divert flow: To divert flow to different zones in the wellbore, allowing selective production of different reservoir intervals.

Monitor well performance: To provide real-time data on well-performance, including flow rates, pressures, and temperatures, allowing operators to make informed decisions about production optimization and maintenance.

Enhance well completion: Used in well-completion operations, such as gravel packing and sand control, to improve well performance and prevent formation damage.

101 R RN LANDING NIPPLES
LANDING NIPPLES AND LOCK MANDRELS

ACT ‘X’ and ‘R’ Landing Nipples and Lock Mandrels ACT ‘X’ and ‘R’ Landing Nipples are run into the well on the completion tubing to provide a specific landing location for subsurface flow control equipment. The common internal profiles of these landing nipples make them universal. ACT ‘X’ Landing Nipple is used in standard weight tubing. ACT ‘R’ Landing Nipple is typically used with heavyweight tubing. The completion can have as many selective nipples with the same ID in and sequence as desired on the tubing string. This versatility results in an unlimited number of positions for setting and locking subsurface flow controls. The flow control, which is attached to the required ACT ‘X’ or ‘R’ Lock Mandrel, is run in the well via the selective running tool on slickline.

1-ACT-TUBING-RETRIEVABLE-SAFETY-VALVE-1
ACT TUBING RETRIEVABLE SAFETY VALVE

Tubing Retrievable Surface Controlled Sub Surface Safety Valves form part of production string. Hydraulic control line extending from the valve to the Wellhead connects to a part on the outside of the valve. The opposite end of the control line connects to the Wellhead. Hydraulic pressure applied through this control line acts on hydraulic pistons within the valve. The force generated moves the flow tube down against a power spring and tubing pressure, causing the flapper to open. Maintaining this hydraulic pressure allows unrestricted well production through the valve. Releasing the hydraulic pressure causes the flow tube to move up by the action of the power spring, thus allowing the flapper to the closed position.

4-LOCKOUT-TOOL-1 (1)
DEFORMATION LOCKOUT TOOL

Deformation Lockout Tool is made to permanently lock the TRSSV Wi open position. This tool is a combination mechanical & hydraulic tool. Applied tubing pressure will move the flow tube of TRSSSV downwards keeping the flapper fully open. When tubing pressure is increased further, the deforming dogs will penetrate into the TRSSSV flow tube, making it permanently deformed. This deformation of the flow tube will prevent it fern traveling back into the closed position thus keeping the flapper locked In open postion.

STANDING-VALVES-AND-SEATING-NIPPLE
STANDING VALVES AND SEATING NIPPLES

ACT Standing valves and companion seating nipples are normally used in intermitting or chamber lift wells at the bottom of the tubing or chamber. The seating nipple is an integral part of the tubing string. The standing valve seats on the No-Go of the seating nipple and seals in the honed bore of the nipple to prevent the fluid from flowing back into well bore when high pressure gas is injected under a slug of fluid. ACT manufactures E-3 type of standing valve, in all popular sizes. A complete line of seating nipples are available to accept the standing valves.

DESCRIPTION & SPECIAL FEATURES OF STANDING VALVE
The E-3 Equalizing Standing Valve has a standard fishing neck and may be equalized and retrieved by wireline. The equalizing feature allows the operator to open ports below the valve and seat without lifting the hydrostatic head. This feature in many cases eliminates the need for an operator to pull a wet string of tubing. This valve may also be used as test plug for testing tubing to check pressure leaks above the valve. Carbide balls are available for severe service in sandy wells.

SEATING NIPPLES
The E Seating Nipples are precision nipples that contain a honed bore to accept and seal the standing valve.They are offered in a wide range of sizes compatible with the tubing string and a large selection of bores for different size standing valves.
