PETROLEUM AND NATURAL GAS PRODUCTION
INDUSTRY
A
Acidizer
Controls pumping and blending equipment
to acidize, cement, or fracture gas or oil wells and permeable
rock formations: Consults with SUPERINTENDENT, DRILLING AND PRODUCTION (petrol.
& gas) to determine well conditions, pipe sizes,
and amounts of acid, cement, or fracturing chemicals to be used.
Gives
directions to OIL-WELL-SERVICE-OPERATOR HELPER (petrol. &
gas) to unload pipes, fittings, and chemicals, and to correct pipes between
pumps and well, using handtools. Mixes acids,
chemicals or dry cement according to service specified by customer. Observes
meters and pressure gauges to regulate quantity and consistency of materials
and to control pump pressure. May perform routine maintenance
on vehicles and equipment. May be designated according
to specialty as Acidizer (petrol.
& gas); Acidizer, Water
Well (construction); Cementer, Oil Well (petrol. &
gas); Formation-Fracturing Operator (petrol. & gas).
Acidizer Helper
Assists OIL-WELL-SERVICE
OPERATOR (petrol. & gas) in controlling blending and
pumping equipment to treat oil or gas wells and permeable rock formations
with cement, acid, or chemicals: Drives truck equipped with acid pumps,
mixers and related equipment to well site. Unloads and assembles pipes and
pumping equipment, using handtools. Dumps acids, cement, or
other treating materials in mixer to blend solution. Opens
valve as directed to admit specified amounts of solution into well.
Dismantles and loads equipment on truck after treatment. May be designated according
to duty performed as Acidizer Helper
(petrol. & gas); Cementer Helper (petrol.
&
gas); Formation-Fracturing-Operator Helper (petrol. &
gas).
Acoustical Logging Engineer
engineer Measures sonar, electrical,
or radioactive characteristics of earth formations in oil- or gas-well boreholes
to evaluate productivity of oil- or gas-bearing reservoirs, using sonic,
electronic, or nuclear measuring instruments: Signals HOISTING ENGINEER
(any industry) to lower instruments into well, observing oscillograph
and meters on control panel to verify operating condition of instruments.
Turns dials on control panel to adjust instrument for specified recording
and starts recording device when instruments reach bottom of borehole. Prints copies of recorded
graphs in truck darkroom [DEVELOPER (photofinishing)]. Interprets
graphs for customer to indicate identity, porosity, oil- or gas-bearing
content, and productivity of geological formations. Measures
borehole diameters, direction of borehole, and inclination of geological
strata, using microcalipers, directional indicators
(clinometers), and dipmeters. May be
designated according to measuring instruments used as Acoustical Logging
Engineer (petrol. & gas); Nuclear Logging Engineer (petrol.
& gas).
Analyst, geochemical prospecting
core analyst; laboratory tester Tests
sand, shale, and other earth materials to determine petroleum and mineral
content and physical characteristics: Performs routine chemical or physical
tests of earth samples in field or laboratory to determine content of hydrocarbon
or other minerals indicating presence of petroleum and mineral deposits.
Tests core samples brought up during well drilling to determine permeability
and porosity of sample, fluid content of sand and shale, salinity of drilling
mud, and other conditions affecting oil well drilling operations.
