WALKWAYS, HANDRAILS, STAIRWAYS Q.ty one (1) complete set of walkways, handrails and stairways. V-door ramp is incorporated in the Pipe Handler. AUTOMATIC DRILLER / WOB CONTROLLER. Drilling condition can change foot by foot, so it will be necessary to reach the best balance between max drilling speed and min wear on bits and tools. The hydraulic hoisting system solves this problem with a pressure balanced feeding device with "automatic driller / WOB controller", that "senses" the down-feed speed at any depth and, depending on the formation characteristic, adjust the feed automatically and instantly. The "automatic driller / WOB controller" function allows keeping constant the determined weight on bit while drilling. During workover operations it is frequently necessary to power the lifting line in order to "float" the weight. The "automatic driller / WOB controller" solves this problem acting as described for the drilling operations with a pressure balanced feed system that "senses" the weight at any depth and adjust feed automatically.

TOOL BOX Complete with combination wrenches and tools for ordinary maintenance. VERTICAL RACKING SYSTEM BINS Q.ty 17 racking bins and fingers to vertically rack the following quantities: • 272 Lengths of 5” Drill Pipes (12,000 ft approx using Range 3 DP) • 18 Lengths of 6 ½” Drill Collars • 03 Lengths of 8” Drill Collars FULL AUTOMATIC PIPE HANDLING SYSTEM The system includes the following main components: • n. 1 central pivoting mast on bearing slewing ring, complete with power unit and control panel; • n. 1 arm and clamp for drill pipe radial and vertical handling; • n. 1 arm for pipe stabilization in vertical position; • n. 1 hydraulic jib crane, inserted in the mast top head, complete with hydraulic winch for site service, 17 metric tons (37,400 lbs.) lifting capacity. The proposed pipe handling system makes transport as well as the drilling operations and string extraction from well very easy, safe and fast, keeping the operator out of drill floor in safe position. Drill pipes and drill collars handling system: a) By means of the pivoting mast the system automatically move the pipe from the vertical bin down in the mouse hole. Each pipe, which may have a length different from the standard range in use, is kept at the right height by means of a hydraulic clamp installed in the mouse hole. b) The top drive scopes out from the well center (operation controlled from the driller’s cabin) and positions itself on the mouse hole center. The driller descends the top drive to pick-up the pipe in the mouse hole and moves back to the well center in order to add it to the drilling string. c) The automatic driller makes the operator free. The pipe handler, while the driller is working between the mouse hole and the center well, will prepare automatically another pipe in the mouse hole. This pipe is ready to be taken from the top drive as per sequence b. d) For the tripping out the sequence will be backwards. e) As concerns the casing running, by means of the jib the operator can take the casing from a special designed horizontal pipe rack and position it in the mouse hole. f) The top drive scopes out from the well center (operation controlled from the driller’s cabin) and positions itself on the mouse hole center. The driller descends the top drive to pick-up the casing with the casing elevator and moves back to the well center in order to add it to the casing string. g) The system allows the utilization of standard lifting devices, such as links and tubular elevators.
