LOCATOR-TUBING-SEAL-ASSEMBLY

LOCATOR TUBING SEAL ASSEMBLY

ACT Locator Tubing Seal Assembly is the most basic packer sealing system for packers incorporating a sealing bore. It is run in the well on the production tubing string until its No-Go shoulder locates on the to of the packer. This positions one or more seal stacks in the packer’s seal bore and establishes a seal between the packer and tubing. When a locator tubing-seal assembly is landed in a packer, the tubing is normally set in compression to compensate for any contraction of the tubing during treating operations. However, it is not always possible or desirable to slack off sufficient weight, particularly in deep deviated wells. In such cases, additional length must be added to the packer’s seal bore using seal bore extensions and to the locator tubing-seal assembly using a combination of spacer tubes and additional seal units.

SEAL-BORE-EXTENSION

SEAL BORE EXTENSION

ACT Seal Bore Extension is used in completions where seal bore packer is used as a production packer and tubing movement is expected. Seal Bore Extension provides sufficient seal bore length so that long seal assemblies accommodate tubing movement while always remaining in the seal bore. Multiple seal bore extension can be coupled together using a concentric coupling to obtain more seal bore length. Seal Bore Extensions are available for all sizes of seal bore packer. Seal Bore Extension are manufactured from materials that comply with NACE MR0175 STD. For SSC resistant metallic material.

Application:
Completions with seal bore production packers where tubing movement is expected.

Benefits:
Easy to install
Low cost solution
Facilitates tubing replacement

ANCHOR-LATCH-SEAL-ASSEMBLY

ANCHOR LATCH SEAL ASSEMBLY

The ACT Anchor Latch Seal Assembly positions the seal units in the polished bore of the packer at the bottom of the available stroke. With a slight amount of set-down weight, the anchor latch will snap into the top thread of the packer. This feature allows the upward pull to be applied to the tubing string to positively confirm proper location and operation.The process to release the anchor is an upward pull combined with right hand turns of the tubing at the latch. The releasing mechanism of the anchor makes it ideal for completions where tubing movement is not desirable.
Standard anchor latch assemblies are manufactured from materials that comply with NACE MR0175 standards for sulfide stress cracking-resistant metallic materials and fitted with seal stacks with metal backups. Viton, Aflas, and Chevron seals are available for hostile conditions, such as high-temperature, high-pressure, and sour environments.

FEATURES:

  • Easy snap-in-snap-out procedure
  • Prevention of seal movement
  • High-performance seals available for hostile environments
PACKER-RETRIEVING-TOOL

PACKER RETRIEVING TOOL

The ACT Packer Retrieving Tool is required to retrieve seal bore hydraulic set retrievable packer. Each packer has a unique retrieving tool but all have same basic design. Latch feature latch into the top thread of the packer. A pull shear the shear screw of collet support and release the packer. If packer cannot be released with the help of right hand rotation collet will be free from safety nut and latch can be backed out.

PACKER MILLING TOOL

General Description
The ACT PRS Packer Milling Tools (Packer Retriever) is an internally engaging fishing tool designed for the retrieving of production packers. With its accessory components (Stinger, Bushing and Mill Shoe) it passes through the bore of the packer, mills the packer slips loose and pulls the packer after it has been milled over, all in one trip. A Packer Retriever is assembled with the proper size slip to engage the bottom of a specific bore packer, and made up on the lower end of sufficiently long stinger (extension) to permit the Retriever to be lowered completely through the packer during the milling operation. The Bushing is provided with a box connection at its lower end to attach the Stinger, also a pin connection at the lower end for attaching Mill Shoe, and a pin or box connection at its upper end for connection to the run-in or fishing string.
OPERATION:
Make up a complete ACT PRS Packer Milling Tools consisting of Retriever, Stinger, Bushing and Mill Shoe. Make sure that the tool is compatible with Casing and Packer sizes and will permit proper and safe operations of the milling and retrieving operations.
Lower the fishing string until the Mill Shoe contacts the slips of the packer. Milling operations may begin until drill off conditions are established. Generally, light drill loads should be used to start to enable the shoe to cut the thin bevel upper parts of most packers away until full mill shoe face contact is established. Additional weight may be added to establish optimum conditions. Rotary Speeds must be established that are sufficient with a given weight, to burn or abrade the carbide particle matrix away to expose the successive new cutting edges of carbide particles. When this condition is established the Mill Shoe will cut almost any metal with maximum efficiency. Start circulation and right-hand rotation to mill away the slips and seating element of packer. When the packer begins to slide down the hole, stop rotation, raise the fishing string to engage Packer Retriever with packer and then pull the assembly and fish from the hole. The best condition of removal for most makes of full bore production packers is to mill up the upper slips and approx. half of the packing element before retrieval is attempted.
TO RELEASE THE RETRIEVER
For any of several reasons, it may be required to release the Retriever from the packer. Release of the Retriever is accomplished by elevating the fishing string until weight is indicated. Lower the fishing string about three to four inches. Rotate the string right hand and slowly elevate the string to withdraw the Retriever from the packer.
CONFIRM THE FOLLOWING:

  • That the Retriever is assembled with the correct size slip for the packer to be
    That the Stringer is sufficiently long to permit the Retriever to pass completely through the
    That the Bushing and Mill Shoe are the correct size for the casing
  • Make up complete assembly to the fishing string. (Scrapers or drift tools should be run prior to running the Milling Tool to depth. The casing in which the packer is to be removed should be washed clean to the packer top and a fluid and pump equipment must be selected that will clean the mill shoe and remove all cuttings from the hole as the packer is mill-up)
  • Lower the Retriever in to the hole on the fishing string and pass it through the packer. The Retriever must clear the packer bore and be in a free position below the packer before milling or rotating of the string. If there are restrictions below the packer such as perforated nipples, landing subs or tail pipe, extensions must be used to position the packer retriever well below these points so that the rotation of the string will not foul the Packer Retriever. Now, raise the fishing string slowly and carefully until it takes weight. This ensures that the Retriever will engage the packer seat.


MAINTENANCE
To guard against mis-runs and to prolong the life of the ACT PRS Packer Retriever it should be completely disassembled, thoroughly cleaned, lubricated and reassembled before storing. Exterior surfaces may be either painted or lubricated to prevent rust and deterioration.

INDEXING-MULE-SHOE

INDEXING MULE SHOE

The ACT Indexing Mule Shoe facilitates stab in of seals into seal bores, even in deviated wells. The work string does not need to be rotated to orient the mule shoe. Axial movement of the work string against an obstruction rotates the mule shoe. If it still fails to enter the bore, the work string is lifted to re-engage the internal J-mechanism and the mule shoe will again rotate when set down load is applied.

KEY BENEFITS:

  • Protected spring. Spring is not exposed either in the inner or outer portion of the tool
  • Spring cannot be overstressed, as set down weight is taken through a load shoulder in the tool
    Internal bearings prevent spring wind-up during the indexing process

APPLICATION:
Stabbing in seals into seal bore in deviated wells.

HYDRAULIC SETTING TOOL

ACT MODEL D, F AND ERD PACKER, can be set on tubing or drillpipe using a wireline adapter kit and a hydraulic setting assembly. These setting assemblies are particularly useful for setting permanent packers in high-angle, deviated wells such as those drilled offshore. The hydraulic setting tool assembly and packer are run to setting depth on the tubing string and a ball is dropped to the ball seat in the setting tool. Sufficient tubing pressure is then applied to set and pack off the packer. The pressure or combined pressure and tubing tension, parts the release stud in the adapter kit and frees the setting assembly from the packer for retrieval. The HST has a bottom connection that accepts common wireline-setting tool adapter kits.

APPLICATIONS:

  • Deviated or horizontal wells
    Large-casing packers
  • Wireline-set seal bore packer completions


FEATURES, ADVANTAGES AND BENEFITS:

  • The HST accepts common wireline adapter kits, enabling it to set all ACT permanent and retrievable seal bore packers
  • The HST enables the well to be circulated before the packer is set, preventing debris accumulation
  • The heavy-duty HST construction enables the packer assembly to be pushed into place in high-angle and horizontal wells, enabling the packer to be set where wireline deployment is difficult or impractical
