OWI Global Awards Winners

December 9th, 2021 by

Proud to say we’re winners in the Best Project Outcome category at this year’s OWI awards

When Aker BP ASA demanded a forward thinking company to seal 30 of their wells, BiSN is who they turned to.

Using our patented BiSN Wel-lok™ technology, our team set a world record for the heaviest bismuth alloy plugs ever – providing a permanent, gas tight, non-permeable seal with a 3000+ year life expectancy – infield tested and delivered ahead of schedule for our customer.

Thanks to all our team for an excellent job well done.

World-first offshore packer repair

October 25th, 2021 by

$30m and 12 months saved in world-first offshore packer repair with our barrier technology.

We delivered a world first to bring a high rate offshore well in Australia back into production faster by performing a rigless repair to a leaking production packer. By deploying our Wel-lok™ PRT (Packer Repair Tool) on a wireline, the major Australian operator, Woodside Energy shortened project execution by over 12 months and saved $30m compared to HWU intervention – eliminating the need to remove the production string from the well.

The V0 rated sealing of the casing annulus by our bismuth-based alloy Performance Barrier Technology created a new, enduring seal in the production tubing with no restriction to production flow.


New tool manufactured and delivered in just four days

October 19th, 2021 by

During the abandonment of a well, off the California coast, a major operator identified that traditional cement wasn’t providing the quality of seal they desired, as the well was leaking gas up a cemented annulus – we acted fast to ensure the well was abandoned with no environmental impact. 

By leveraging our unique alloy-based Performance Barrier Technologies platform, we were able to manufacture and deliver a tool up to the job, in just four days – with over 5,000 pounds of bismuth-based alloy – to seal out an 18 5/8″ casing.

As an alternative to traditional cement plugs, this was the fourth tool successfully deployed during their current P&A campaign on addressing leaking gas in cemented annuli (vent flow). Even the first to get the seal of approval from the local whales!

Successful abandonment in the Permian Basin

September 29th, 2021 by

After multiple failures with cement squeezes, learn how Chevron eliminated casing pressure and gas bubbles at surface using our bismuth-based alloy Performance Barrier Technology and by simply deploying our Wel-lok™ CRT on wireline. The well was successfully bubble tested, resulting in zero bubbles at surface, allowing the operator to complete the permanent well abandonment. The technique is now being used successfully on an additional two wells. Read the case study

Middle Eastern Expansion

September 22nd, 2021 by

We are delighted to announce the signing of an exclusive agreement with the Middle East’s leading energy service provider – AlMansoori Specialized Engineering – to further expand our deployment activity in this hugely important region.

A partnership that will leverage the vast experience and geographical reach of AlMansoori’s 4,000 employees and operations across 15 countries, to take our offering to the next level.

This agreement will complement our customer global base which includes Shell, bp, ExxonMobil, Aker BP ASA, Chevron and ConocoPhillips.

BiSN signs groundbreaking deal with ADNOC

September 21st, 2021 by

Wel-lok™ contract officially signed with ADNOC Group

We are proud to announce the signing of a contract with ADNOC Group which will result in the first ever deployment in the Middle East that utilises BiSN’s ground-breaking Wel-lok™ technology.

Scheduled to take place in Q4 of this year – this will mark an important deployment in the intervention sector for BiSN. Keep a look out for more updates as the project gets underway.

Decom North Sea 2021 Award

May 24th, 2021 by

We are honored to have received the Decom North Sea 2021 Award for Technical Innovation in Decommissioning.

The Wel-lok M2M technology has been deployed in over 200+ applications throughout the world. In our most recent campaign with Aker BP ASA in the North Sea, our tools were able to provide a rigless and time saving solution through a permanent and environmental barrier to over 30 wells.

Wel-lok technology utilized in the North Sea

May 12th, 2021 by

On the 12 May BiSN was proud to have our Wel-lok technology utilized in the North Sea with Aker BP ASA on their Valhall Field Center campaign. The results speak for themselves by reducing the time and equipment needed to effectively provide a permanent, environmental barrier and top seal for the over 30 wells.

Meet the Team Andrew Graham

April 27th, 2021 by

Andrew started in 2019 in the Houston, TX facility as a thermite technician. Being a key member of the thermite team, he performs qualification, R&D and troubleshooting tests to ensure the quality of thermite that we manufacture. He sees a new project as an exciting endeavor to be able to assemble instrumentation and perform new tests.

BiSN is a small-medium sized business which is one of the many reasons Andrew enjoys working here. He stated that his “hard work has a bigger impact” on the overall success because of the size of the company. Andrew is also a proud veteran of the US Army Artillery. We thank you for your service to our country and dedication to BiSN.

Sustainability is our future

April 26th, 2021 by

Looking at sustainability today versus ten years ago, the focus on the future and what natural resources will remain is vital to most, if not all, organizations. Between the environmental, social and economic pillars of sustainability, BiSN has developed an innovative technology to provide a safe and natural barrier within the energy industry. This barrier is a final seal blocking the emittance of gases, unwanted water, and pressures within downhole applications.

Our most recent campaign in the North Sea was with Aker BP at their Valhall Field. BiSN provided over 30 bismuth alloy plugs to the top section of the wells as the final barrier prior to abandonment. With the largest alloy plug placed within a 30” casing, it earned the title of world record holder for using a tool weighing in at over 30,000 lbs. By the end of the campaign, 24 plugs of this size were deployed, with 6 smaller (24”) plugs, and all tested to show no emittance of gases (or bubbles) over a 14-day trial. The overall sustainability of these tools remains in line with several UN Sustainability Goals: (9) Industry, Innovation, and Infrastructure and (14) Life Below Water.

The campaign with Aker BP has proven that BiSN is an environmental barrier. In addition, the PSA Norway qualified the Wel-lok M2M sealing technology as a barrier for the Seal 2 application in the Valhall wells. With a gas tight, non-permeable seal in place, the conductors could be safely cut and removed with no release of hydrocarbons. Aker BP featured the BiSN technology recently in their 2021 first quarter Sustainability Report. (A copy can be viewed below.)

BiSN’s Wel-lok M2M technology is a metal-to-metal downhole sealing solution developed to provide a permanent seal through a thermite heat ignition and a rapid solidification process of eutectic bismuth alloy. The use of bismuth alloy is advantageous because once it is heated, the metal liquifies and is equal to that of the viscosity of water. The liquid bismuth alloy can then filter through porous locations prior to solidification, as opposed to conventional methods such as cement or resin.
