BLANKING CAPS & PLUGS
ACT Blanking Caps and Plugs are used for installing gauges and/ or bleed off valves to hold pressure from above, below, or both. These are available for use on all Quick Unions and are equipped with NPT ports.
LUBRICATOR ACCESSORIES
Union Cross Over Adapters are utilized to provide a transition between otherwise incompatible unions made by the same or different manufacturers. These adapters are designed with a Union Box Up and Union Pin & Collar Down and are always rated, both in terms of service and pressure. Any combination of end connections are available.
Floor Block (Hay Pulley) is used to bring the wireline down to a position where it is horizontal from the lubricator tree to the wireline rig. It also shifts the point of wireline pull from the top of lubricator to the base of the lubricator tree and reduces side loading of the lubricator. Pulleys are available in aluminium or composite material for lighter weight.
A Wireline Clamp is used to clamp the wireline while raising and lowering the lubricator and during fishing operations.
A Wellhead Connection is
used to connect the bottom of the wireline valve to the top tree connections. The top of the connection fits the bottom of valve and the bottom thread of connection is threaded to screw into the particular threads on top of the tree flange connections.
A Telescopic Gin Pole is used to raise the lubricator to the top of the wireline valve and maintain this position while breaking off or making up wireline tool string.
A Load Binder and Chain are used to bind the gin pole to the tree and to the wireline valve.
Rope Blocks are used to raise and lower the lubricator.
A Lubricator Pick-Up Clamp is used to hook the rope block to pick up the lubricator.
Pump – In – Subs and Plug Valves are used to pressurize the lubricator during hydrostatic testing or pumping in to the well bore when that becomes necessary during the course of servicing operations. Models with a working pressure above 5,000 PSI are equipped with specially designed side ports and accept plug valves with integral unions. Plug Valves are available separately and as a component of Pump-in-Subs. Fitted with a variety of Top and Bottom Connections, – Quick Union connections being most common, – these assemblies are available from 2.50 ID. inch through 6.38″ ID. with WP from 3,000 PSI through 15,000 PSI.
BLOWOUT PREVENTERS
Gulfwell’s ACT Blowout Preventors are designed to prevent the uncontrolled release of oil and gas during wireline operations. It works by applying constant pressure on the wellhead, allowing operators to safely control the flow of oil and gas from the well.
Gulfwell’s Blowout preventors are available in two types hydraulically operated and manually operated, with configurations as desired. Hydraulically operated BOP consists of large, heavy-duty valves that are connected to the wellhead and operate hydraulically using either high-pressure fluid or electric signals. The valves are designed to close quickly when pressure within the well reaches an unsafe level, thus preventing any further flow of hydrocarbons from the well. Manually operated BOP is designed to be operated manually by personnel on the well site, and can be used to shut off the flow of fluid in an emergency situation.
Gulfwell’s Blow Out Preventers are available in light weight and compact models.
- These are easier to install, transport, and operate.
- They also require less maintenance due to their smaller size and simpler design.
- These are more cost effective as they require fewer resources for installation and operation.
- These can be used in tighter spaces or remote locations with limited access, making them ideal for offshore drilling operations where space is at a premium or difficult to reach areas such as the Arctic Ocean or deep-sea rigs.
- They provide a greater degree of safety due to their ability to quickly seal off the wellbore in case of an emergency situation such as an unexpected increase in pressure or gas flow from the wellhead while allowing drilling operations to continue uninterruptedly without having to shut down the entire system for repairs or maintenance work on site.
Gulfwell blowout preventors are available in sizes ranging from 2-1/2” ID through 6- 3/8” ID and 3,000 PSI through 15,000 PSI working pressures. Contact the Gulfwell representative for details on pumps, fittings, hoses and other accessories.
PUMP IN SUBS
ACT Pump-In Sub is placed between the wireline BOP and the Wellhead. It is basically used to pump the fluid in to the well when the wireline BOP is closed. Pump-In Sub can also be used for injection of inhibitors and for collecting samples. The top and bottom have quick union connections and a side outlet with a wing union connection.
CHECK VALVE UNIONS
ACT Check Valve Unions are designed to seal off well pressure in the event of the wireline parting from the tool string. The steel ball is forced against the metal sealing area by the well pressure from below. The check valve unions are manufactured as one piece body and are assembled below the stuffing box or grease injection control head. The internal check valve assembly can also be fitted as an integral part of the stuffing box or grease injection control head. This helps to reduce the height of lubricator assembly.
QUICK TEST SUBS
ACT Quick Test Sub is designed to save rig time while pressure testing a lubricator rig up, before exposing it to well pressure. When multiple wireline runs are required, the lubricator has to be tested each time the bottom connection is broken, and much time can be lost. After performing the first pressure testing of the whole string, subsequent pressure test can be made using the Quick Test Sub to verify the integrity of the joint disconnected, rather than testing the whole lubricator assembly. This is done by connecting a small hand pump to the Quick Test Sub and testing the two O-Rings seals from outside.
The Quick Test Sub s installed either above or below the BOP and becomes the joint that is disconnected each time to insert and retrieve tools from the well.
CHEMICAL INJECTION SUBS
ACT Chemical Injection Sub, also known as a liquid chamber, is designed to inject inhibitor, chemicals and de-icing agents on to the wireline during routine operations. It is installed below the stuffing box or grease injection control head and used in wells with an H2S environment, dry gas, or conditions which cause hydrate problems. The Chemical injection sub/liquid chamber incorporates a two litre chamber for fluid which is pumped by using a high pressure hand pump. It utilizes replaceable felt packings to coat the wireline and prevent the chemicals from passing downhole. The injection port is equipped with a check valve to prevent fluids from escaping. The design extends wireline and stuffing box packing life and create a smoother wireline operation.

GREASE INJECTION CONTROL HEADS
Grease Injection Control Head is required to obtain a seal when using braided cable.
Principle of Operation: Grease is injected at a pressure higher than the well pressure (approximately 20% higher). The grease fills the interstitial grooves between the braided line strands. The most critical components of the grease injection head are the ‘flow tubes’. These should be approximately 0.010” ID larger than the measured outside diameter of the line. A seal is effected by pumping grease at slightly above the well pressure. This action causes pressure drop to occur across each tube. The pack off at the top is closed fully in order to gain control of the pressure before running the cable.
The following equipment is required to operate the grease injection system
Ancillary Equipment:
- Grease control head
- Compressor (Back-up system essential in high pressure situations)
- Grease reservoir
- Grease pump
- Connection hoses
- Dual BOP system
Use :
The following factors will effect the volume of grease required :
- Clearance between the flow tubes and line
- Temperature
- Well pressure
- Line speed
- Line size
- Grease viscosity
HYDRAULIC TOOL CATCHERS
ACT Hydraulic Tool Catchers are a safety devices designed to catch the tool string when it is pulled too quickly in to the top of the lubricator and the wire is stripped from the rope socket. The tool catcher will engage the uppermost fishing neck and prevent the loss of tool string in to the well bore. It is designed to be fail-safe because it is permanently in the catched position and requires hydraulic pressure to release. The hydraulic tool catcher is available for 1.00” to 2.313” fishing necks. The multi catch option is also available in two ranges: 1.00” to 1.750” and 1.375” to 2.313”
