FLUID LUBRICATION OF ROTARY & TURBO OIL DRILLING EQUIPMENT

DURING October and November 1957 B.P. Exploration Co. Ltd. made a number of trials at their Egmanton oilfield in Nottinghamshire to compare the relative merits of turbodrilling and rotary drilling techniques. Although the details of these results are not of direct interest from a lubrication point of view the part played by the drilling fluid in these techniques is worthy of note.
