Canada’s existing natural gas pipeline network is being considered to help store and distribute high pressure hydrogen, when blended with natural gas, to support transition to the hydrogen economy. The importance of this topic to Canada is well document in the Federal Government’s call to action “Hydrogen Strategy for Canada”, which includes benefits such as: (i) positioning Canada to become a worlding-leading supplier of hydrogen technologies, (ii) employing hydrogen as a key enabler to reach net-zero emissions by 2050, and (iii) generating more than 350,000 high paying jobs, including unique opportunities for indigenous communities and businesses.

This paper presents preliminary results in our effort to develop a hydrogen permeation testing method using electrochemical hydrogen charging to screen the comparative performance of candidate polymer barrier coatings as applied to pipeline steel. So-called sandwich membrane assembles with the non-conducting polymer coating located in between two conducting metallic (steel) plates were used for this purpose. Significant variation in the oxidizing current density transients was observed from the replicate testing conducted, which made it difficult to determine the more typical permeation barrier performance of the candidate polymer coating under study. Changes to the sandwich membrane assembly design are proposed to improve more reproducible transient and thus a more meaningful interpretation of the permeation barrier coating performance. An attempt was also made to use the slow strain rate technique to comparatively screen hydrogen embrittlement susceptibility of polymer-coated steel samples when immersed in hydrogenated water. Initial measurements using uncoated AISI/SAE 1144 free-machining steel samples did not reveal a susceptibility to hydrogen embrittlement.

Scale is an adherent deposit of inorganic compounds precipitated from water onto surfaces. Most oilfield waters contain certain amounts of dissolved calcium, barium or strontium salts. The mineral scale can be formed by chemical reactions in the formation water itself, by mixing of formation water with injected seawater, or by mixing of the well streams of two incompatible oilfield waters. In carbonate reservoirs, when calcium is deposited as calcium sulfate or calcium carbonate scale, a loss of production and increased maintenance expenses can result. Therefore, effective mitigation of scaling potential is of importance to the oil producers.

Tetrakis(hydroxymethyl)-phosphonium Sulfate (THPS) is a very common active ingredient in oil and gas biocides. While product labels provide broad guidelines application dosing the lowest effective dose of THPS is difficult to determine. Site water chemistry and bacteria biology variability will affect the dose need to achieve the desired level of bacteria population control. For these reasons biocide dose response studies are commonly conducted on solutions containing bacteria to determine the effect of treatments before application.
