I was interested in SM's mention (re: info from his newly acquired "Tullow Team") of the possibility of using
"Spacers" to centralise the wireline in the wellbore to prevent differential sticking (or on outcrops)
(I think he described them as - spacers attached to the wireline ?)
I have NOT found
ThoseSpacers yet - but I think they might look something like these
Spacers - attached to wireline Tools - but NOT to the Wireline in this case.
They are used to support wireline tools as they are lowered or raised inside vertical, deviated or horizontally-drilled oil wells !!
Its a Pity IVZ /Baker couldn't have discovered
Spacers for use in Mk1 !!
https://patents.google.com/patent/US7090007B2/enA centralizer for use in oil well wireline tool-strings comprising a central mounting rod and floating spring mechanisms between which a number of jointed centralizer arms are connected.
Centralizers are commonly used to support wireline tools as they are lowered or raised inside vertical, deviated or horizontally-drilled oil wells. Some tools require to be centred in order to make proper measurements or otherwise perform their intended function, and centralizers are often used to provide a smooth passage along deviated holes, including reliable entry of the tool-string when passing from a large section of borehole into a smaller section.
