Seal-Tite International

ACC Corporate is the sole agent for Australia, New Zealand & Papa-New Guinea.

Seal Tite International has an outstanding record of sealing leaks in oil and gas wells worldwide.

This is accomplished through engineered services combined with a unique sealing technology.

Seal Tite technology is mainly used worldwide to rectify SC- SSSV, Wellhead and Christmas Tree leaks and have the well back in production in a matter of hours.

Other leaks which Seal Tite technology works very well are:-

• Down Hole Equipment Leaks.

• Pipeline Leaks.

• Umbilical Leaks.

• Micro Annulus Leaks.

• Sub Sea Well Control Leaks and Equipment Leaks.

Using a single skilled technician and a small self-contained equipment package, the STI product is injected through the subsurface safety valve hydraulic system until the leak is corrected.

Before the introduction of Seal Tite technology, a subsurface safety valve leak could require the operator to shut-in the well.

The only remedy was to pull the safety valve by means of a costly wire line or work over operation.

Seal-Tite key aims:-

* To maintain and enhance production.

* To avoid sub sea, wellhead and down hole leaks in environmentally sensitive areas.

* To address these problems in the most cost-effective manner.

Some Problem Leaks and Seal-Tite Results.

North Sea

Problem:

A leak in the SC-SSV control system required the operator to use a restrictive insert velocity valve.

This restrictive valve limited production.

Result:

Besides correcting the leaking valve using STI sealant, the most significant aspect of the report is that production was increased from 200,000m3/d to 340,000m3/d by eliminating the need for the restrictive velocity valve. This equates to a 68 per cent increase in production for a fraction of the cost of a rig work over.

Well known oil and gas industry identity and ACC Managing Director & Founder, Mark Liesegang said "This is just one of many examples where the use of Seal-Tite product and services has provided a cost effective alternative to repair the SC-SSSV control line rather than the use of a work over drilling rig".

Alaska

Problem:

An operator had leaks to eight separate pack-off assemblies.

In selecting the wells to be worked on, the operator chose a broad spectrum of leak rates, from minor to severe.

It was the operator's expectation that Seal-Tite would only be able to seal approximately one half of the leaks.

Seal-Tite was able to cure all eight wells.

Result:

Using its pressure activated sealant; Seal Tite was able to cure all eight pack-off leaks and continues to cure Alaskan leaks on a regular leak remediation program.

Gulf of Mexico

Problem:

Pre job diagnostics indicated a tubing leak.

Just prior to the Seal Tite operation, a spinner survey was performed.

Based on the survey, it was determined that the leak was near the packer.

Result:

The Seal Tite pressure activated sealant was delivered to just above the packer by a dump bailer.

Pressure was released from the casing and the shut-in tubing pressure was maintained at approximately 5000psi.

A differential pressure was created from the tubing to the casing annulus and the sealant was carried through the leak path.

The process was repeated six times with six separate dump bailing operations. With each dump bailing operation, the casing pressure was reduced.

At the conclusion of the sealant application, the casing pressure had been reduced to zero pressure.

This seal has been in place since early in 1999.

Brazil.

Problem:

An operator had a leak in the umbilical line leading to the well’s SC-SSV.

The leak was in excess of 1.8 litres a minute.

Result:

Over the course of a two-day operation involving the use of different sealant formulas, the leak was sealed.

The different formulas were necessary to, first, reduce the leak and, with another formula, eliminate the leak.
