The Retrievable Bridge Plug(RBP) is a high-pressure packer style bridge plug used for multiple selective zone treating and testing operations. The RBP is designed to set in tension or compression, which makes it ideal for shallow applications to test wellhead for deep, high-pressure applications. The plug is designed with a large internal by-pass to prevent swabbing when running and retrieving. The by-pass closes during the setting of the plug and opens prior to releasing the upper slips to equalize pressure when unsetting.

Oil well completion tools include: Subsurface safety valve, wireline retrievable subsurface safety valve, single string production packer, dual strings production packer, ESP packer, mechanical set packer, permanent packer, compensation device, bridge plug, sliding sleeve, nipples etc.

The RedSeal Dual Overshot Packer has been developed to provide a dual seal barrier in surface drilling systems used on jack-up and platform applications.

The RedSeal Dual Overshot Packer has been developed to provide a dual seal barrier in surface drilling systems used on jack-up and platform application. The system provides the operator with a primary and secondary seal system to mitigate potential environmental spills.

The system has been developed with a similar design philosophy to the RedSeal Packer system developed for drilling riser telescopic joints but does not include a facility for refill of the packer online as the seal element is a static seal and not subject to the dynamic motion associated to the RedSeal Packer system. Physically the RedSeal Dual Overshot Packer is shorter than traditional single packer systems allowing the system to be utilised in riser systems where stack-up heights are critical.

RedSeal Dual Overshot Packer can be supplied with a dedicated control system to monitor seal actuating pressure and (upon actuating pressure loss to primary seal element) switch automatically to the secondary seal, thereby minimising any environmental impact.

Cameron diverters are fully customizable for your floater and jackup rig operations, respectively. Designed for reliable, efficient use, each system consists of a housing, outlet valves, running tools, controls system, diverter assembly, overshot packers, and storage skids.

The CF-B diverter supports up to 47-in rotary tables and is qualified up to 2,000 psi. Packers can be split and hinged to allow them to be changed out with pipe in the hole. J-slot type running tools are entirely mechanical and require no hydraulics.

The SAZ-IX Mechanical Production Packer is a retrievable, double-grip compression- or tension-set production packer that can be left in tension, compression, or in a neutral position, and will hold pressure from above or below. A large internal bypass reduces the swabbing effect during run-in and retrieval, and closes when the packer is set. When the packer is released, the bypass opens first, allowing the pressure to equalize before the upper slips are released.

The SAZ-IX also features a patented upper-slip releasing system that reduces the force required to release the packer. A non-directional slip is released first, making it easier to release the other slips.

The SAZ-IX can easily convert to SAZ VI-X with the advantage of being able to set on Electric line or hydraulically- just remove the shear screws and install drag blocks and drag block springs. An On-Off Tool Stinger with a Wireline Plug installed can be attached to the top of this packer. This packer can then be lubricated in the hole and set under pressure. Once set, casing pressure can be bled off, and the tubing with an On-Off Tool Overshot can be run and latched onto the packer. The Wireline Plug can then be removed.

Fishing tool is a special fishing drilling tool used to retrieve fallen objects from the borehole. At any stage of the operation, the drill rig operator will encounter unexpected situations, such as falling drill string, stuck pipe, missing drill bit, etc. The equipment that falls into the well is called "fish" or "trash", and the tools used to remove the equipment are called "fishing tools." Sometimes it may be necessary to use "fishing tools" to retrieve older wellbore equipment, such as packers, liners, tubing, or any stuck objects in the well. The drilling tools for fishing must be retrieved from the borehole in order to continue drilling operations.

Overshot is a very common fishing tool. The main fishing object is a smooth tube fish, which belongs to the external fishing type (i.e. catching the external surface of the fish).

Taper tap and die collar are common fishing tools for fishing the inner hole of the string. They are used for fishing the inner hole with holes such as tubing, drill pipe, casing milling pipe, packer, water distributor, etc. It is made of high-quality alloy steel and especially heats treated. It has the advantages of high strength, high toughness, and simple buckle making.

TIANHE Series 10 Sucker Rod Overshot is a professional fishing tool, designed for engaging and retrieving sucker rods, couplings, and other tubular from inside tubing strings.

TIANHE Series 10 Sucker Rod Overshot consists of a Top Sub, Bowl, Grapple, and a Guide. According to the size of the fish, there are two types of grapples available: Basket Grapple or Spiral Grapple. TIANHE Series 10 is a simply tool to use, no matter engaging or releasing operation, in fact just need to rotate the  fishing string on right hand.

When overshot nears the top of the fish, slowly rotate to the right as the overshot is lowered over the fish. After the fish is engaged,allow right-hand torque to release from the fishing string. Then raise the fish by pulling upward on the fishing string.

Bump down or drop the weight of the fishing string against the Overshot to break the hold of the grapple within the Bowl. Elevate the fishing string while slowly rotating it to the right until the Overshot has cleared the fish.

GAOTON Series 150 Releasing and Circulating Overshot is an external fishing tool for engage, pack off and retrieve tubular fish, especially for fishing drill collar and drill pipe. The grapple of the overshot can be designed for different sizes of fish, so one overshot can be dressed with different size of grapple components for fishing different sizes of fish.

GAOTON Series 150 Overshot consists of three outside parts: Top Sub, Bowl, and Standard Guide. The Basic Overshot may be dressed with either of two sets of internal parts, if the fish diameter is near the maximum catch of the Overshot, a Spiral Grapple, Spiral Grapple Control, and Type “A” Packer are used. If the fish diameter is considerably below maximum catch size (½” or more) a Basket Grapple and a Mill Control Packer are used.

Within those famous China oil and gas overshot manufacturers, GAOTON is a professional such supplier, producer and provider, welcome to wholesale petroleum and oilfield API overshot from our factory.

PARVEEN Hydraulic-Set Dual Bore Permanent Production Packers are the hydraulically set onetripcompletion packers, ideal for high volume production in high angle, extremely deviated well.These packers feature the largest possible bore through combined packer and seal accessory.The packer is run on the hydro-set anchor latch seal unit which is made up in the top of the packer via the left-hand threads on the latch and is set by applied tubing pressure. The DB packer requires some type of temporary plugging device such as a shear out plug or wireline blankingplug located close to the end of the tubing.

The Dual Bore Permanent Hydraulic Set Packers have been designed to give maximum strength, uniformity of setting pressure and standardization of all alloy materials for H2S service.
