Rotational Type Port CollarUnexpected stage cementing operations can involve substantial expense, risk or both. Including a TAM Port Collar in the casing string provides a reliable back-up means to improve cement quality in a variety of completion operations.

I n d u s t r y ’ s P r e m i e r P o r t C o l l a r For decades, TAM International has manufactured the premier Port Collar for the Oil and Gas Industry. TAM Port Collars provide a selective communication path from inside the casing to the annulus. They engage, open, close and release with minimal work string movement. With sizes available from 2 7/8” through 26”, their proven track record is attributed to solid design and precision machining.

F e a t u r e s : TAM Port Collars operate with a simple (up/down or rotate) movement of the inner string and Combo Tool.

Special features such as Metal-to-Metal seals, a locking closed mechanism, slim line versions, premium threads, and NO Rotate to Release versions are available.

Metal-to-Metal seals are useful in corrosive environments and in casing strings where casing integrity or a gas-tight environment is critical.

In premium Port Collars, Metal-to-Metal seals are standard, and lock pins are used to prevent the sleeve from opening accidentally after final closure.

TAM Port Collars are proven highly reliable in multiple open/close cycles required in selective production and integrity testing applications.

When the spring-loaded Dogs of the Combo Tool engage in the inner sleeve profile and the Port Collar is opened, string weight can be set on the tool, allowing for improved operating reliability of the Motion Compensator on floating drill ships.

P e r m a f r o s t - T w o S t a g e O p t i o nIn areas where cement displacement to the surface is critical such as the permafrost regions in Alaska and Siberia, TAM Port Collars offer a fast simple contingency for second stage cementing operations.

When displacement efficiency of the primary stage is not satisfactory, a Combo Tool is run in hole to open the TAM Port Collar and pump the additional stage. If the primary cement operations are successful, no activation of the TAM Port Collar is required.

D e e p W a t e r - L a r g e O D C a s i n g For casing sizes larger than 18 5/8”, TAM Port Collars have been used since 1984 for multiple stage cementing operations to flush cement from around the surface casing near the sea floor to allow movement of the subsea wellhead.

Stage cementing casing improves cement displacement through “flow” zones in deep water and shallow applications.

E x p l o r a t i o n W e l l O p t i o n s A TAM Port Collar can be located in the intermediate casing string above the shoe to provide a means to flush the annulus after primary cementing operations.

If the exploratory section below the intermediate casing proves nonproductive, the casing can be cut and retrieved prior to abandonment.

If the exploratory section is productive, an additional cement stage can be pumped through the TAM Port Collar prior to running production casing and completing the well.

U n d e r B a l a n c e d L i n e r D r i l l - I n The TAM Port Collar can be run as part of the drill in liner and utilized for cementing after reaching TD with the liner/bit system.

Using the Port Collar allows full well integrity by setting the liner hanger and the packer prior to releasing from the liner. Once the inner string is pulled, the check valve at the shoe and liner hanger packer provide complete well control.

A second trip with the Combo Tool is required to squeeze cement behind the liner or two (2) Port Collars can be run with circulation established between Port Collars while maintaining well pressure integrity.

An inner string with the TAM Combination Tool opensthe Port Collar.

Opposing seals straddle the opened port to perform stage cementing through the Combination Tool & Port Collar.

Port Collar is closed by the Combination Tool, tested. No cement drillout required.

H i g h A n g l e H o r i z o n t a l W e l l s - Multiple Port Collars and TAM Casing Annulus Packers can divide production zones in horizontal wells. This type of completion provides the flexibility to cement some sections, gravel pack others and leave other sections open.

Horizontal Completions TAM Port Collars are run as an integral part of the horizontal liner with an inner string and Combo Tool to provide a “ONE TRIP” system of completing a horizontal well, including cementing the build section even when running slotted liner or screens.

Multiple Port Collars can be run in the liner completion for use as gravel packing ports or selective treating and testing, including proppant fracturing.
