makes well-drilling safer mm This remarkable material seals off gases--gives wells and human lives a protection you never thought possible! "D AROID, properly used, eliminates the vents loss of circulation, fissures and danger of blow-offs, makes wells safe, caving. . protects the lives of drillers. Poured down the well, Baroid builds a firm, erosion-resisting arch that effective ly seals off the dangerous strata--those which bear trouble-making gases. Thus it prevents the eruptions which lead to disaster. Baroid is a specially processed form of barytes--a fine white powder that will stay in suspension almost indefinitely. It is so fine that it will penetrate under pres sure almost any formation encountered in drilling operations. Furthermore, Baroid has remarkable lubricating qualities, assisting the drill bit in cutting through the hardest forma Even on JStibleJFobs!) TTSUALLY "mud-fluid" is.associated only with rotary drilling,operations. . Yet a "Baroid-fluid" was used with entire success on a cable tool Winfield,'. Kansas, U. S. A. It was found that the fluid was heavy enough to seal off thejQ?; gases, yet not heavy enough to ihterfer^'|> with the dropping action of the tools. , Truly, this new material offers the most thoroughgoing protection.
