Subject: did not agree when formations tested where the same did not agree when formations tested where the same - ?When discussing cutting mechanics, it is important to consider what is happening at in-situ conditions. In 1955, Cunningham and Murray described the effect of hydrostatic pressure on drilling rates. They noted that field and laboratory drilling rates (up until that time were all done at atmospheric conditions) did not agree when formations tested where the same. They built the micro-bit drilling rig so they could use core samples from the field. |
