Inspectors should be great at:

• Estimating sizes, distances, and quantities; or determining time, costs, resources, or materials needed to perform a work activity.
• Observing, receiving, and otherwise obtaining information from all relevant sources.
• Identifying information by categorizing, estimating, recognizing differences or similarities, and detecting changes in circumstances or events.
• Inspecting equipment, structures, or materials to identify the cause of errors or other problems or defects.

Analyzers will often perform the following tasks:

• Identifying the underlying principles, reasons, or facts of information by breaking down information or data into separate parts.
• Using relevant information and individual judgment to determine whether events or processes comply with laws, regulations, or standards.
• Assessing the value, importance, or quality of things or people.
• Compiling, coding, categorizing, calculating, tabulating, auditing, or verifying information or data.

• Assessing costs and estimating the production capabilities and economic value of oil and gas wells, for evaluating the economic viability of potential drilling sites.
• Monitoring production rates, and planning reworking processes for improving production.
• Analyzing data to recommending placement of wells and supplementary processes for enhancing production.
• Specifying and supervising well modification and stimulation programs for maximizing oil and gas recovery.
• Directing and monitoring the completion and evaluation of wells, well testing, or well surveys.
• Assisting engineering and other personnel for solving operating problems.
• Developing plans for oil and gas field drilling, and for product recovery and treatment.
• Maintaining records of drilling and production operations.
• Conferring with scientific, engineering, and technical personnel for resolving design, researching, and testing problems.
• Writing technical reports for engineering and management personnel.
• Evaluating findings for developing, design, or testing equipment or processes.
