At Zwernsdorf in the SEB Matzen area of the Soviet Oil Administration (SMV), four new Soviet turbo-drilling rigs have: been operating since December 1953 or January 1954.. First parts of this drilling rig arrived some time in September 1953, and all its constituent parts have been kept under special guard ands ity protection. 2. The rigs are supposed to be a Soviet invention and a Soviet crew has been assigned to teach Austrian foremen. at SMV how to operate the turbo rig. The Soviet crew is using housing especially constructed for them; also Austrian workers have complained that the Soviet crew is receiving preferential treat- ment because it is allowed to keep three sets of working tools at each rig,and. because the Soviets demand exact replacement parts khhen there are breakdowns, instead of making improvised repairs as is the custom of the Austrian workers. 3. The four turbo rigs have been erected at a location near Zwernsdorf where, two years ago, a drill rig was blown up by a gas eruption. The SMV had not been able to get this eruption under control::andtthe well had been throwing up each day approximately 500,000 cubic meters of salt water mixed with gas. The rigs were erected.around the opening of the eruptive well in the circular area which was covered with mud. 4. The principle underlying the working mechanism of the turbo rig is very simple, Instead of having the turning drill bit fixed to the drilling tubes, which are rotated from above the ground by a turntable, the drill tubes in the turbo rig are kept in a fixed position so that they can not turn. At the end of the dril- ling tubes, a small powerful welter propelled turbine is attached. The totating shaft of the turbine is allegedly attached directly (without clutch or transmission) to the drilling bit. 5. To propel the turbine, water is pumped from four coupled pumps through the drilling tube to the turbine with a pressure of aboutlj,Q00 atmospheres. The pumps operate with a maximum capacity of 300 atmospheres each. Under normal working conditions, if the ground is not too hard and rocky, the pressure of 1,000 atmospheres will 25 YEAR RE-REVIEW TE ARMY DATE DISTR. 14 Anril .1954 NO. OF PAGES NO.
