Retrievable Cement Bushing
Retrievable Cement Bushing Image
Overview During the Liner Hanger cementing operation a seal is required between the inside diameter of the liner and the work string. This seal forces circulation fluid to exit out of the liner shoe and then back up the annular space. The pressure required to force the fluid to take this course pushes upward on the liner sealing device. This force must then be offset by the set down weight of the work string to prevent the liner seal from being “pumped” upward and out of the liner top. To limit the set down weight requirement, a Retrievable Cementing Bushing (RCB) is often used. The Cementing Bushing locks into the liner top in order to transmit the majority of the upward force into the liner instead of the work string. Features
  • Features two sets of seals, one which seals the ID of the Setting Adaptor and one set that seals to the OD of the Slick Joint
  • Contains locking Dogs:
    • When locked the RCB is anchored inside the Setting Adaptor where it sits during cementing operations
  • Designed with extra length to allow the operator to pick up and verify the liner Running Tool has properly released
  • When pulling out the workstring, the Slick Joint reaches the undercut area beneath the locking Dogs and they retract inwards, this allows the RCB to be retrieved when pulling out of the hole

Production Tools
Formation Protection Valve
Formation Protection Valve Image

Overview

The FPV valve is a bi-direction sealing device used in conjunction with ESP artificial lift equipment. When a production stinger is landed into this tool, the well bore is free to flow through the valve assembly and into the lift system. When the production stinger is removed in order to service the lifting system, the bi-directional valves close. Once the bi-directional valves are closed, the well bore is sealed from above and below. This allows for servicing of the ESP equipment with or without kill fluids. Fluids are prevented from moving either into or out of the formation by the dual barriers.

Features

  • Bi-directional valves for positive sealing of the well bore from both above and below
  • Prevents formation damage associated with kill fluid during ESP servicing
  • Valves contain both a soft elastomer seal and metal-to-metal sealing areas
  • Stinger strokes completely past valves to protect the inner working of the tool from production debris
  • Wiper seal cleans heavy viscous fluids from stinger
Production Stinger
Production Stinger Image

Overview

The Production Stinger is a device which is run directly below the ESP pump. When the ESP is being installed, the production stinger is used to trip open the bi-directional valves within FPV system. After the system is open, this stinger acts as the flow conduit during production. The Production Stinger contains a internal check valve. When the ESP is operating, this check valve is open and allows flow from below. When the ESP is not operating, the check valve isolates all upper annulus fluid. Above the check valve are angled holes which allow produced fluids to exit the stinger and enter the ESP. The Production stinger has external seals. These seals direct all production flow through the stinger ID and past the check valve. These seals are landed into the polished bore of the FPV assembly. The stinger is used to space out the ESP pump assembly so that it is not landed in excessive compression during the heat up of production. If the ESP pump needs to be removed from down hole, the production stinger is retrieved by straight pick up. The production Stinger is retrieved along with the ESP.

Features

  • Straight pick up and set down it trip open bi-direction FPV valve/s.
  • Stinger provides both check valve and external seals which isolate the upper annulus when ESP is non-operational.
  • Provides flow exit for production above the FPV assembly

Centralizers
Centralizers Image

Overview

Centralizers are run during cement jobs to ensure the casing is positioned evenly in the middle of the wellbore. This is important because cement should be distributed evenly around the casing annulus to ensure an adequate seal between the casing and formation. An uneven cement job can lead to contaminated cement or an inadequate seal which can cause drilling fluid to leak into a section of the formation that is supposed to be sealed off. Centralizers are especially important in deviated sections of the wellbore because the casing will tend to ride on bottom. Depending on its class, a centralizer can be outfitted with hinged and slip-on designs, as well as stop collars, wire scratchers and other accessories.
