ELECTRICAL-LINE SPLICER

Splices conductor cables used to lower electrical testing or surveying instruments into oil or gas wells or boreholes, using handtools: Unwraps armor strands (protective covering) from end of cable. Strips insulation from stranded conductor cable, using stripping pliers. Cuts ends of conductor cable, using pliers. Clamps cable ends together in vise to form butt joint. Solders joint, using silver solder and iron. Wraps joint with insulating tape to form smooth insulation of same diameter as original cable. Wraps armor strands over joint. Trims ends of armor strands, using cutters, to form smooth butt joints and solders joints, using silver solder and iron. May test conductor cables, using equipment, such as voltmeters and capacity and resistance bridges.

electrical-logging engineer

engineer; electrical-prospecting operator Measures resistance of earth formations to electrical charges, using electrical apparatus to obtain data for locating rock strata favorable to further petroleum exploration activities: Transports electrical equipment and instruments to designated locations, and directs and assists in laying out and connecting cables, electrodes, instrument panels, and other electrical equipment. Adjusts electrical instruments to eliminate electrical interferences from earth currents or weather conditions. Opens and closes circuits to send electrical current through electrodes into earth. Reads dials and records data of millivoltmeter readings at various receptor points along cable to detect loss of potential due to resistance of earth formations. Diagnoses cause of malfunctioning of instruments and cables and makes repairs.

Electrical Prospector

Studies structure of subsurface rock formations to locate petroleum deposits: Conducts research, using geophysical instruments such as seismograph, gravimeter, torsion balance, and magnetometer, pendulum devices, and electrical-resistivity apparatus to measure characteristics of earth. Computes variations in physical forces existing at different locations and interprets data to reveal subsurface structures likely to contain petroleum deposits. Prepares charts, profiles or subsurface contour maps, and determines desirable locations for drilling operations. Directs field crews drilling boreholes and collecting samples of rock and soil for chemical analysis of hydrocarbon content. May specialize in particular instrumentation and be designated Electrical Prospector (petrol. & gas); Gravity Prospector (petrol. & gas); Magnetic Prospector (petrol. & gas); Seismic Prospector (petrol. & gas).

ELECTRICAL SUPERVISOR

Supervises and coordinates activities of workers installing, repairing, and inspecting oil field electrical equipment, such as primary and secondary power lines, transformers, submarine cables to offshore well sites, and electric motors. Inspects work for compliance with government electrical codes and company standards. Performs other duties as described under SUPERVISOR (any industry) Master Title.

electronics supervisor

research shop Supervises and coordinates activities of INSTRUMENT-MAKER AND REPAIRER (petrol. & gas) in constructing, maintaining, and repairing mechanical and electronic instruments and equipment used in petroleum prospecting and oil and gas well surveying and servicing: Assists subordinates in constructing, maintaining, and repairing instruments and equipment, using handtools. Inspects work of subordinates, using testing instruments. Performs other duties as described under SUPERVISOR (any industry) Master Title.
