[QUOTE=Alf;34737]I don’t know what rigs you have worked on… but it is done this way, and certainly on Transocean rigs (I worked one last year where this was the norm)… every time the driller trips in or out of the hole, a trip sheet is made up beforehand showing bit depth against stands of pipe run or pulled. It’s a simple matter to add an extra “column” showing tool joint positions in relation to the BOP rams.
I can send you a spreadsheet if you don’t believe this…[/QUOTE]
For specific operations, with the setting of plugs, tools, packers etc, detailed info is tracked in relation to position in the well and bop.
For the vast majority of drilling operations, a driller cannot tell you where each tool joint, stabiliser, motors, collars, hvwt and other non-shearables (250-500 tooljoints) is in relation to all the rams, annulars etc, 8 different positions in the stack at any point in time.
BS.
They have to stop and locate them…then verify against the paperwork.
When the bushings flew out of the well, and the TDS landed in the company mans office, do you think he turned around and looked at your spreadsheet?
Spreadsheets are what is killing this industry.
The driller needs a real time display, in cyberbase, that shows a tooljoint in relation to all his rams as they pass through the stack. This is achievable, it is something that drillers have asked for for years.
