ISO 10414-1:2008,Petroleum and natural gas industries – Field testing of drilling fluids – Part1:Water-based fluids.
This part of ISO 10414 is based on API RP 13B-1, third edition, December 2003 and ISO 10414 (all parts) .
Annexes A to H and K of this part of ISO 10414 are for information only. Annexes I and J are normative.
In this part of ISO 10414, where practical, U.S. Customary (USC) units are included in brackets for information.
This test procedure is a method for determining the mass of a given volume of liquid (equivalent to density).
Drilling-fluid density is expressed as grams per cubic centimetre or kilograms per cubic metre (pounds per gallon or pounds per cubic foot).
The mud balance is the instrument generally used for drilling-fluid density determinations. The mud balance is designed such that the drilling-fluid holding cup, at one end of the beam, is balanced by a fixed counterweight at the other end, with a sliding-weight rider free to move along a graduated scale. A level-bubble is mountedon the beam to allow for accurate balancing. Attachments for extending the range of the balance may be used when necessary.
