PEH:Coiled-Tubing Well Intervention and Drilling Operations
The chronology of modern-day steel CT technology development appears to begin in the early 1950s with U.S. Patent 2,567,009, "Equipment for Inserting Small Flexible Tubing into High Pressure Wells," awarded to George H. Calhoun and Herbert Allen on 4 September 1951.
Overview. The new Sieg SX4 mid-size mill is an impressive machine. It's big. It's heavy. The laws of physics dictate that the mass of a solid object increases as the cube of the linear dimensions. This formula does not hold exactly for a mill, since it is not a uniform solid object, but as you scale a machine up to handle larger work, th
AVR Generators (Digital or Analogue): AVR generators feature either a digital or analogue Automatic Voltage Regulator designed to control voltage. Whether digital or analogue the AVR attempts to keep the output voltage more or less constant, regardless of the load.

More than ever, public opinion is demanding the design of stable embankments as part of tailings disposal systems to aid in abating air and water pollution. Even though many areas have no restrictions requiring industry to impound its tailings, great interest has been generated through universities, industry, and Government in developing sound engineering principles regarding disposal problems.
