That is the same job wot I did do, for a company that was called Dresser Atlas when I started.
'Wireline engineer' it is called.
I went on to be a training instructor on the subject.
Dont miss it one bit.
I've always been a topsides person, what goes on subsurface is witchcraft as far as I'm concerned.
Dresser Atlas, did that eventually become part of Atlas Copco, or get subsumed elsewhere?
Nothing to do with Atlas Copco, although they do have a huge portfolio of companies. Useless facts, the business started out making steam locomotives, and a bright spark designed tools to speed things up, so Atlas evolved into a tooling supplier. Major breakthrough was a rock drill that could be operated by 1 man instead of 3, using (I kid you not) “the Swedish method”. Later bought a compressor company in Belgium so they had both the tooling (now huge stuff for rock breaking) and power source (compressed air) in house.
I used to work for Seaco, part of Baker Production Services (until that was closed down due to some senior management malfeasance and I was transferred to Baker Oil Tools) and we made wireline winches, wireline tooling and mechanical downhole pressure and temperature recorders. The winches were hydraulically driven, and had air turbine powered cab lights. The Hydraulics, though, were powered by Ford diesels, and we had one back that had gassed up. Quite novel taking off the head and seeing all 6 pistons at TDC.
My neighbour was a wireline operator. He aged about 10 years every 2 week shift he had offshore!
