Oil and gas well loggers and testers, and their helpers, cooperate closely with drilling and service rig crews. In general, loggers and testers:
The occupational group to which oil and gas well loggers and testers belong includes several occupations. These include hydrocarbon mud loggers, coring operators, drill stem testers, pressure testers, wireline operators, and slickline operators.
Hydrocarbon mud loggers, also called hydrocarbon data analysts, analyze mud from the well to learn about rock formations. In general, they use instruments to:
Mud logging results help determine drill bit selection and drilling rates. They may indicate a need for core sampling or drill stem testing.
Coring operators take core samples. Geologists, geophysicists, and engineers analyze the samples to provide information about subsurface geology. This helps to determine the potential productivity of a well. In general, coring operators:
Drill stem testers perform tests on the fluid in rock formations. This helps to determine the potential productivity of an oil or gas well. With assistance from their helpers, they:
Drill stem testers, who also are qualified to use equipment that pressure tests casing or tubing for leaks, may be called pressure testers.
Wireline and slickline operators lower special instruments or tools into wells on a slender, flexible, metal cable called a wireline or slickline. For more information, see the Wireline Operator and Slickline Operator occupational profiles.
Oil and gas well loggers and testers are most often on call 24 hours a day. They often work long hours. They are always under pressure to complete their work so the rig can continue its regular activity. The work environment around a rig is noisy, dirty, and hazardous. Performing their work safely is key. The work may require lifting heavy tools and equipment.
Hydrocarbon mud loggers work primarily in small, onsite laboratories during drilling operations. Coring operators, drill stem testers, wireline operators, and slickline operators work mostly outdoors. They often work in adverse weather conditions. They may work in isolated locations for long periods of time.
They must be able to lift at least 25 kilograms.

Most loggers and testers are trained on the job. There is no minimum education requirement, but many employers prefer high school graduates. Related courses, such as math, chemistry, geology, electronics, and mechanics are assets. Experience working on drilling or service rigs is also an asset. Loggers and testers need a valid driver’s licence. Those who operate heavy trucks must have a Class 1 or Class 3 operator’s licence with heavy truck and airbrake (Q) endorsement.
Most employers provide in-house training programs for new employees. They also provide ongoing courses, such as blowout prevention, for experienced employees. They may expect employees to become certified in:
Workers can gain technical knowledge and advance more quickly by taking courses in different aspects of drilling or service operations. Energy Safety Canada, formerly ENFORM, in Calgary and Nisku (near Edmonton), offers courses for those who work on drilling and service rigs. It is the industry’s safety association, but other organizations also offer this training.
