USA Chapter Events

Monthly Lunch & Learns

At these regular monthly events, networking and lunch are followed by a concise, topical technical presentation. With an emphasis on case studies, this bite-size event consistently provides members and their guests with a look at the latest and greatest that the industry has achieved.

Lunch & Learns are typically held the 2nd Tuesday of every other month. Notifications will go out if one is postponed or cancelled.

We’re starting an offshore section of the ICOTA USA chapter. This section is going to focus on all types of intervention work being performed in the Gulf of Mexico, from new deep water subsea completions to P & A work on the shelf. The goal is to bring to light the existing and new challenges of today’s offshore well intervention industry and help solve these issues by improving communication and promoting technical awareness.

We are always accepting abstracts for presentation. Contact me if you are interested

2015 Lunch & Learn Schedule

TOPIC: Premature Coil Tubing Failures & Pumping Equipment Damage Related to Microbial Influenced Corrosion
Speaker: Scott Sherman, Senior Technical Advisor, Trican 

Norris Conference Center  [driving directions] and [detailed map]
816 Town & Country Blvd
Houston, Texas

The upstream oil and gas industry is observing an influx of microbial influenced corrosion (MIC) related equipment damage. This recent occurrence of MIC is coincidental with the switch to unconventional water sources. As fresh water for fracturing operations and well interventions becomes less available, operators are forced to use alternative water sources such as recycled frac water and other low quality water supplies. In some instances, recycled frac water is sold from one operator to another for operations on other pads. Regardless of the water source for a particular well treatment operation, the same water-hauling equipment and tanks are used for successive hydraulic fracturing operations. This ‘communal’ use of water hauling and temporary water storage equipment is an ideal situation for bacteria to move from one water repository to another. Even if the water source used to supply water for oilfield operations is free from harmful bacteria, it may become contaminated - in transport or temporary storage vessels - before it is pumped downhole. It is unknown how many times frac water has been recycled or its biocidal history. This talk is an overview of MIC related coil tubing failures and pumping equipment damage. Metallurgical analysis and microbial analysis of the scale and representative water samples has been conducted to determine if the corrosion was the result of sulfur-reducing bacteria (SRB) or merely This talk will further explore the potential source(s) of the bacteria, what has been done to mitigate the problem, and some of the challenges associated with treatment of MIC.

Scott Sherman is a professional engineer who has worked in the oil and gas industry for over 11 years. Scott is a Senior Technical Advisor at Trican Well Service in Calgary, Canada. Scott is named as an inventor on over 17 patents, Scott’s inventions range from solid state energy conversion devices to downhole tools and completion systems. Scott has been working on identifying and mitigating microbial influenced corrosion for almost 2 years and has found evidence of biological corrosion in upstream oilfield equipment such as frac blender tubs, coiled tubing rotating joints, and coiled tubing. Scott has published 2 papers relating to microbial influenced corrosion, one of which was featured in the June 2015 SPE Journal of Petroleum Technology.
