Features & Benefit
In order to significantly improve the safety & life span of stabilizers UDT has offered, after extensive engineering studies and field experience, the Integral Blade Stabilizers. "UDT Make" integral blade stabilizer has a single body made of 4145 H modified alloy steel fully heat-treated to 285-341 Brinell hardness and 54 Joules minimum impact strength. UNITED stabilizers are available in either near-bit or string-type. Connections are cold-rolled, phosphatized, coated andequipped with thread protectors. These are gauged to API standards. “UDT Make” Integral Blade Stabilizer are sturdy, rugged and easy to repair and maintain tools which can be safely used in highly deviating wells for side tracking and fishing etc. Our stabilizer shall provide 250 to 360 degree hole wall contact and the rib surface shall be hard faced as described under heading “hardfacing”.
“UDT Make” Replaceable sleeve stabilizer comes in two different types : Onepiece body constructions or with a two-piece body with the sleeve blocked in the middle. Different size sleeve may fit same body. It is composed of a 4145 H AISI heat treated steel mandrel and a sleeve made of special alloy steel. Hard facing on the blades can be any of the four different types offered in section "Hardfacing”.
This type of stabilizer is often used in fields where repairs and hard facing of the blades are not available and is thus a time and money saving tool.
Like the conventional gas lift valves, UDT line of wireline retrievable gas lift valves include, casing-pressure-operated, tubing-pressure operated (fluid-operated) types in a full selection of sizes. Each valve has a large dome volume and Monel multi-ply bellows. Every valve is constructed of stainless steel and monel, selected on the basis of corrosion resistance and strength. Bellows are silver-soldered by induction soldering technique and all valves are factory tested for high reliability.
Wireline retrievable gas lift valves provide self-contained packing as a sealing means in retrievable mandrels and each valve has integral check-valve to prevent flow between tubing and casing.
“UDT Make” 'AF' Series gas lift valve is designed to open or close on a fluid load signal, When a predetermined fluid load is reached, the AF Series Valve opens. This allows casing gas to enter the tubing string and lift the fluid to the surface. The AF Series Valve will remain open until the fluid load drops to the closing pressure pre-set on the valve.
The AF Series Valve uses a cross over seat which allows the valve to accept a check and to fit into a conventional type mandrel.
The AF Series Valve is intended for use on wells having a high continuous flow rate. It is also well suited to multiple string completions using the annulus as a common source of injection gas.
Not affected by temperature. No dome charge is used in the valve, therefore the valve is not affected by temperature.
“UDT Make” Orifice Valves is a retrievable valve used to install in the side pocket mandrel prior to circulation. It prevents the pocket damage from abrasive well fluids while circulating. Efficiency of back check valve provides large flow capacities. Positive sealing feature of back check valve provides protection from intrusion of production fluid into casing annulus. Various orifice materials (SS, monel, inconel & tungsten carbide) available to meet application requirements.
Orifice sizes available for this valve design range from 1/8 through 7/16 inch in 1 inch size and from 1/8 through 51/64 inch in the 1-1/2 inch size, thus making them suitable for a wide range of operating conditions.
"UDT Make" Dummy Valves is a retrievable dummy valve used to blank off communication between tubing and casing. In new installations, dummies can be retained in the mandrels until gas lift valves are required to maintain production. Then, dummies are pulled and gas lift valves installed by wireline. During the life of the well, gas lift valves installed above the fluid level can be replaced with dummies to block off injection gas. They are available in 1 and 1- 1/2 inch sizes.
Latches are available in a wide range of designs for use with retrievable gas lift and circulation valves to be installed in side pocket mandrels and make it easy to install and remove Gas Lift Valves, very little force is required to operate these latches to keep the wireline time to a minimum. These are available in 1”-1.1/2” sizes.
Running Tools are used to install several wireline equipments such as appropriate latches with valves in side pocket mandrels.
Pulling Tools are designed to remove subsurface devices, with outside fishing necks, from a well. Featuring collet type dogs with a large latching area, they will withstand repeated impacts and save considerably on dog repair.
KICK OVER TOOLS
UDT Kick over tools are used to install and retrieve flow control devices in Side Pocket Mandrel that have an integral orienting sleeve. The orienting sleeve aligns the kickover tool, enabling installation or retrieval of flow control devices for gas lift applications.
“UDT Make” Side Pocket Mandrels offer the advantage of providing an internal profile that guides the valve being installed towards the pocket. These mandrels feature a one piece-pocket, an orienting sleeve for positive kickover tool alignment in highly deviated well and a tool discriminator to exclude larger slick line tools from the product area. The pocket is offset to clear the tubing bore which maximize the flow area and permits passage of tools through the mandrel without meeting restriction. The external shape allows dual string installations without requiring a reduced mandrel ID. These mandrels are available in a variety of tubing connections in both EU and / or premium thread configurations and incorporate all the design features required by customer. These are available in both orienting and non-orienting design. Our side pocket mandrels are available for 1.1/2” & 1” Gas Lift Valves for tubing sizes upto 4.1/2” OD. These mandrels can accept 1” & 1.1/2 OD side pocket devices.
UDT manufactures a wide range of gas lift mandrels in L-80, N-80 and P-110 grade tubing. These Mandrels are designed to accept 1” & 1-1/2” Gas lift valves and reverse flow check valve. The Gas Lift Mandrels are manufactured with heavy duty properly chamfered steel lug welded to their outside surface so as to protect the valve & check valve during running in and pulling out operation. The mandrels will be duly heat treated and stress relieved. All threaded ends shall be provided with suitable thread protectors.
