... and lead to operational problems during drilling and completion. To study the effect of rheology on settling, a laboratory tool. the sag tester, was designed, consisting of a small pipe, 45 degree inclined, and a vertical collector pipe attached to the low side of the inclined tube. The pressure...

.... Some ten to fifteen other wells have experienced wellhead settling (casing contraction). Several wellheads have gone down 25 to 50 cm, requiring wellhead and piping modifications. This paper discusses the casing and cement designs used historically, field observations and explanations for the casing...

... to minimize skin friction in turbulent pipe flow of Iraqi crude oil. Large-scale pipes of 1", 2", 3", and 4" sizes have been used in the experiments. A friction reduction up to 63 percent has been achieved when 9 ppm of additive was added to crude oi l. The effects of crude flow rate, pipe diameter...

..., with proper techniques, would carry water from the holes. These foaming agents, introduced in the last half of the 1950's, permitted extension of air drilling techniques still farther. A combination of oxygen and water establishes a corrosive atmosphere which.can cause excessive corrosion of the drill pipe...
