The branch held its 4th event of the 2019/2020 session at its usual venue, RGU, with a presentation on “The Application of bismuth based alloys to address Oilfield challenges” by, Paul Carragher (BiSN), Lance Underwood (BiSN) and Angus MacLeod (BP).
This was a highly successful joint presentation with IOM3 – The Institute of Materials, Metals and Mining, which has recently celebrated its 150 year anniversary. The BiSN speakers discussed in detail their Wel-Lok sealing technology which utilises a unique combination of a thermite powered chemical heater and a bismuth based alloy to deliver an efficient down hole sealing capability, using standard oilfield deployment methods.
The thermite heater provides the energy to melt the bismuth alloy in situ, allowing the heavy liquid alloy to flow by gravity to the desired location. As the bismuth alloy cools, it expands on solidification to provide a seal. Paul Carragher started BiSN in 2010 with the insight to develop new and innovative sealing solutions for the oil & gas industry, and explained the use of bismuth in downhole sealing applications
Lance Underwood, Principal Engineer at BiSN Oil Tools, who has has over 30 years of experience in the industry, then provided further insights into the development of new technologies for plugs for oil wells, covering materials selection, downhole corrosion control and long-term corrosion testing programmes. He illustrated some of the rigorous testing requirements for downhole oilfield tools including bits, mud-motors, turbo-drills, under-reamers, hammers, and laser drilling.
Angus MacLeod (Senior Intervention Engineer with BP), with 22 years Oil and Gas industry experience, then followed this up with some actual case histories from BP operations worldwide, where this technology has been applied offshore, to shut off water production in open-hole gravel pack completions, as well as the work being done to qualify the alloys, as a permanent well abandonment material. In his current role, Angus is responsible for developing new well technology as part of BP’s Upstream Technology Group, primarily focussed on “Life of Well Surveillance” and “Plug & Abandonment”. The event generated a huge level of interest and many questions were asked, which can be found, together with the answers, on the branch website.
At the close of the meeting, the branch chairman, presented all speakers with a Certificate of Appreciation from the branch.

Particular attention is drawn to the 2020 Corrosion Awareness Day to be held on Tuesday 25th August at, Petrofac Training Centre, Forties Road, Montrose, Angus, DD10 9ET. The day will include several practical demonstrations with teaching, this year themed on fabrication and external corrosion management. Further Details about this can be obtained from the branch Chair: Stephen Tate, email: Stephen.Tate@external.total.com
Angus MacLeod highlighted the many practical applications for this new Downhole Sealing Technology.

The branch opened its 2019-2020 session on 27 August with two linked events on MIC – Microbiologically Induced Corrosion. The well-attended Annual Corrosion Awareness Day (CAD) had a full day teaching programme on MIC risks, mitigations, modelling and bacterial analysis, complimented by an evening visit the following week, to NCIMB Laboratories in Bucksburn and the National Collection of Industrial, Food and Marine Bacteria.
The CAD event featured some excellent talks by Dr Carol Devine (ICR), Drs Laura Tiano and Lone Tang (Danish Technological Institute), Mabel Ntim (Shell), and Drs Ian Laing, Daniel Sandana and Mr Steven Loftus (CAD Co-ordinator), from key Sponsor ROSEN.
Microbiologically influenced corrosion can have a major impact on operators’ CAPEX and OPEX and cause severe environmental damage. A key aim of the CAD workshop was therefore to improve understanding of complex MIC processes, detection of microbiological activity in pipeline systems and management of MIC in the pipeline industry in particular, which has seen many pipelines lost due to internal corrosion in the North Sea sector.
Many analytical techniques were discussed in detail, including qPCR analysis (amplification and quantification of bacterial DNA), traditional culture-based MPN (most probable number), NGS, (next-generation sequencing which has revolutionised biological sciences), Metagenomics (the study of genetic material recovered directly from environmental samples), along with pipeline in-line inspection tools, (deploying a wide range of NDT methods), internal cleaning, chemical treatment and MIC modelling tools for corrosion rate determination.
A lively discussion followed with many valuable viewpoints expressed and with great inputs from the four participating Microbiologists.
The need for an integrated approach to microbial monitoring combining data from multiple techniques, together with taking a fully holistic approach to pipeline integrity management was emphasized to all CAD delegates.
Dr Carol Devine opened the Teaching Programme with a fascinating insight into her career as a Microbiologist entitled “My Life in MIC”.
Dr Laura Tiano (Danish Technological Institute) discusses bacterial sampling options.
Dr Ian Laing, Principal Corrosion Engineer of ROSEN discussed MIC modelling / MIC management, and the vast range of specialist tools available for cleaning and intelligent pigging.
The NCIMB visit on 3rd September built on the previous discussions, with a most informative evening led by Dr Daniel Swan, who was previously Head of Platforms and Pipelines, (now the Genomics Pipelines Group) at the Earlham Institute in Norwich, (formerly The Genome Analysis Centre – TGAC).
NCIMB have 68 years’ experience of preserving, storing, distributing, analysing and exploiting micro-organisms, and are the only privately owned, publicly viewable collection of bacteria in the UK.
A very comprehensive tour of the NCIMB Laboratories followed Daniel’s presentation and recommendations for effective bacterial monitoring strategies, with everyone kitted out in protective clothing to view a wide range of practical demonstrations of bacterial sampling. archiving

This most interesting industrial visit to NCIMB, (the first of two in the 2019-2020 programme), generated many questions, so many in fact the event overran by nearly 90 minutes!
At the close of both meetings, the new Aberdeen Chair, Mr Stephen Tate presented all speakers and organisers with Certificates of Appreciation.
