Gas Watch Sensing System

Gas Watch

■

™

A dependable and proven total gas sensing system, Gas Watch exploits the latest infrared technology to provide drillers with reliable combustible gas measurement information. Functioning Functi oning as a primary sensor sen sor,, Gas Watch is easily added to all existing M/D Totco Totco data acquisition systems. Fast, accurate entrained gas information is essential t o well control and proper identification of production zones. A sample rate of approximately 15 SCFH provides drillers with rapid identification of gas shows in the return mud flow. A warning light at the sensor plus an indication on the NT TracerTM alert personnel if the sample flow is interrupted. Unlike conventional catalytic gas detectors, Gas Watch requires no calibration and is not susceptible to poisoning by contaminants. Source and detector aging is automatically compensated along with compensation for the accumulation of dirt in the optical path. The Gas Watch system continually extracts gaseous samples from the drilling mud via a Gas Trap Trap — a cylindrical agitation chamber mounted at the mud tank. One end of the trap is immersed in the mud to an optimum level, and the swirling motion of the internal mechanism draws mud through the chamber where a slight vacuum provided by the control unit and mechanical agitation releases entrained gases. Sample gas is drawn from the trap through a glycol pot to remove moisture. Within the Control Unit, it passes through an activated carbon purifier to absorb vapors, aerosols, trace moisture, and particles larger than 0.5 micron before going into the infrared sensing module.

Highly accurate, full range infrared sensing technology Simple to install, setup, and maintain Sensor pre-calibrated at factory — no tweaking necessary No chemical reaction in the sensor — no possibili ty of sensor poisoning

Controlled Vertical Drift Indicators (CVD) Setting the Standard Commonly known as a ‘TOTCO”, ‘TOTCO”, the double-recording drift drif t indicator is the most dependable and practical method of mechanically determining the deviation from vertical in a wellbore. Non-vertical wellbores take a toll on the drill string in terms of greatly increased stress and friction. Bits do not cut as efficiently. efficiently. More power is needed to rotate and pull out of a crooked hole. Fishing jobs become more frequent. Redrilling and mechanical holestraightening devices become necessary. necessary. M/D Totco’s Totco’s Drift Indicators can help you drill a vertical hole. They provide the driller with extremely accurate information at frequent intervals, so he can maintain a controlled, vertical course. So simple to operate, virtually any member of the crew can operate the instrument, and he can read the charts with ease. Everything is mechanical so no liquid or electrical equipment is required. The heart of the Drift Indicator System is the Double Recorder, Recorder, which consists of two main parts: an angle indicator and a timing device. Both are sealed in a stainless steel case. The recorder produces a permanent record of hole inclination by perforating a small circular chart close to the center of the chart if you’re drilling true vertical; or off-center in a concentric circle to show you the degree of deviation. Then it repeats th is process a few seconds later. later. Two perforations with the same deviation indicate an accurate record. Instruments and charts are available in 0-7°, 8°, 14°, 16°, 21°, 24°, and 90° values. Very little equipment is needed to accomplish accomplish the recording procedure: A Double Recorder; the Go-Devil assembly that protects it against shock, pressure, and fluid; and a selection of various centralizing equipment.

The no-nonsense Load Watch assures the accurate and continuous monitoring of a wide range of vital crane functions and loads in a variety of applications. Safe and efficient operations are assured, especially in extreme offshore operations. The Load Watch System can be custom-configured to meet almost any user need: the system’s Limited Access feature includes a key-operated selector switch in the data display for customer programming of specific crane configuration (boom length, parts line). Load Watch keeps a close

eye on all lifts, monitoring all critical crane functions to keep load factors within preselected tolerances. Even in offshore operations in rolling seas, the system constantly monitors conditions and warns through intermittent audible and visual alarms when the applied load reaches a predetermined set point of between 80% and 95% of rated capacity. A continuous alarm sounds when 100% to 110% capacity is reached. The Load Watch System can easily fit into your current operations. Its modular modul ar,, lighter-weight electronics electroni cs makes Load Watch easy to install or retrofit regardless of the application. And simple retrofit can give your lifting equipment and operators new capabilities capabiliti es plus better overall control of lifts. The Load Watch System is designed for lifting at dockside, in salvage operations, on cranes on offshore drilling platforms, rigs and construction barges, as well as most land-based crane requirements. Monitoring is factory preprogrammed to given crane make and model and the varying combinations of boom length and load block reeving. With all monitoring functions programmed, the operator simply selects his fall with the push of a button or allows the Automatic Fall Scanning feature to select fall changes automatically automati cally..
