English to Russian Tech/Engineering Petroleum Eng/Sci Drilling

NOTE: I appreciate everyone's input, and it's a blessing to have KudoZ, but I would like this question to be answered only by those who KNOW closely and specifically what the agreement is talking about. If you don't have a picture of the down-hole equipment, I'd rather come up with a translation myself using all the information available from Multitran, Lingvo and Google. Thank you, everyone!

CONTEXT:

Excerpt from a Well Drilling Services Agreement:

The Contractor shall maintain an authentic, legible and accurate history and log of wells drilled on forms and in a manner prescribed by Company, including all measurements required for fishing operations with a record of all down-hole equipment.
