Interwell High Pressure High Temperature (HPHT) Mechanical Retrievable Bridge Plug. We have developed a bridge plug for the oil and gas industry. This is a demonstration of the HPHT Bridge Plug to be used in different applications such as Water Shut Off, Temporary Barrier Plug and Reservoir Well Intervention
THE world’s first high pressure (HP) retrievable bridge plug capable of withstanding a differential pressure of 15,000psi was today (Tuesday, 6 September) unveiled at Offshore Europe by high-technology well intervention specialist Interwell.
Interwell developed the ultra slim, 2.2” OD, HP bridge plug to provide a reliable barrier in extremely high pressure conditions.
The ISO 14310 qualified tool contains an innovative packer back-up design which both compresses and constrains the element, reducing the risk of extrusion in extreme conditions and enables its operation to 15,000psi.
“We have established a new standard with this tool as we are the only company in the industry to develop a plug which can withstand such high pressures and is fully retrievable after use,” says Interwell’s UK managing director, Andrew Louden.
“This tool is a significant development in terms of its global applicability in ultra-deepwater environments, and from our perspective is a further major design and engineering achievement in a portfolio which already includes the highest-expansion ultra-slim bridge plugs available.”
The ultra-slim design of the patented element back-up segments of the HP plug reduces the risk of deployment and retrieval through narrow wellbore restrictions, a crucial operational benefit in high pressure high temperature (HPHT) wells.
Efficiency is further enhanced by each plug taking just one run to set and one to retrieve, providing a reliable and cost effective solution for well interventions.
Jim Laidlaw, business development director at Interwell Aberdeen, says: “Intervening in deepwater and HPHT wells is very demanding. Our key design aim was to develop the slimmest HP plug solutions in the market whilst also minimising operational complexity in these challenging well conditions.
“With a range of plug sizes for 3-1/2” to 7-5/8 casings, the ultra slim HPHT plug design makes it an ideal barrier solution for wellbores with any form of restriction, allowing it to be deployed reliably to the desired depth.
“Our plugs have been designed so they can be used as both shallow and deep barriers, making them ideally suited to workover applications. They can also be used to anchor injection valves and equalisation devices.”
The tool can be run on slickline, e-line, coiled tubing or pipe and as with all of Interwell’s plugs and packers, it features a scale tolerant slip design ensuring that it adequately grips the casing.
Interwell offers some of the most advanced well barrier solutions available in the upstream oil and gas sector, and it is the world’s leading independent supplier of retrievable bridge plugs.
Its product portfolio has already successfully passed qualification testing in gas with very high pressures up to 15,000 psi and at temperatures up to 200°C. The company intends to continue developing plugs which can withstand more extreme conditions using its field proven design.
Each of Interwell’s portfolio of solutions can be tailored to solve individual project requirements with very short lead times, providing a rapid response for clients. Interwell also has in-house testing facilities where they can qualify plugs and packers to the ISO 14310 V0 standard.
In February 2011, the firm opened a new facility in Aberdeen as it embarked on an ambitious international growth strategy. The Aberdeen office has created 17 new jobs within the first 6 months of operations and expects to double in size over the next 12 months.
