The cable passed those tests and worked in the field, but Shell dropped oil shale in favor of more conventional oil and gas options. Shell tested the cables by running them at even higher temperatures, jolting them with extreme power surges, and simulating years of hard use, Karanikas said. (Oil shale is kerogen-rich rock where extreme heat can extract a lot of oil, which is different that oil in shale, which is in ultra-tight rock that is released using fracturing.) Heating cable technology was developed by Shell, which needed electric cables capable of heating rock to 650☏-which required an electric cable that could heat to 1200☏. The company has put a lot of work into more durable ways of connecting cables, which it has patented. The company is working on planning some complicated installations where a splice is required. Salamander’s cables can heat a well more than 7,000 ft long without a splice, Karanikas said. If one of those weak points failed, the rest of the line went out like a string of lights after a single bulb fails, said Scott Penny, general manager for Petrospec Engineering, a partner in the business that installs the heating cables. Older cables required multiple splices to connect 100–200 m sections. “I talked to an operator who told me the reservoir performance when the heater lasted was great, but he would never do it again,” said John Karanikas, the chief technology officer for Salamander, who said that none of its cables has gone out in a customer’s well. It is up against depressed heavy oil prices, the high cost of electricity in some locations, and long memories of heating cables that failed. ![]() Still, those heating cables made by Salamander Solutions are a tough sell. The gains “have proven the economics of continuing the operation of the downhole electric heat and CNRL will be applying to continue the enhanced oil recovery process,” according to a report to the Alberta Energy Regulator. ![]() One of those wells is owned by Canadian Natural Resources (CNRL), which reported that production rose 50% ( SPE 196187). She most likely thinks I’m a loon.Oil production from heavy oil wells in western Canada jumped after an electric heating cable was installed. There’s no way we can’t acknowledge knowing each other, and how we do, and I haven’t shared my mental health history with anyone outside my family and very close friends. I had a visceral reaction to seeing her again and now I’m thinking I can’t face her at the barbecue. This morning I saw a photo on her social media of the neighbour, and it’s my old boss from the old job. ![]() She’s invited us to a barbecue on Friday along with her neighbours. My daughter has a good friend from school and I get along well with her mum. Put the whole awful experience behind me. I quit, went back to my old industry and have been healthy and happy since. After discharge and talking to an occupational therapist I realised that the job and its culture was at the root of all my issues. I returned to that job, hoping there’d be an improvement, but after six months I had a breakdown and was admitted to hospital for a month. It really did not work out, I had literally nothing to do in my new job and I found that very stressful, having come from an industry that was heavy on deadlines but in which I thrived on being busy.Īs the weeks went by, I started waking up at 4am every morning with palpitations, and that anxiety spiralled to the point that I wasn’t functioning very well and had to be signed off work for a few weeks. ![]() Took a substantial pay cut for job security. Five years ago I took a big decision to switch career.
