gas) across construction and extraction environments, from entry-level rig assistance through organizational leadership of multi-site drilling programs.","levels":{"emerging":{"label":"Emerging","statements":["Drill controls and stabilization levers — identify and operate under direct supervision to position and align a drill rig on a standard construction site.","Drilling speed and casing insertion — start and stop the machine following step-by-step instructions from a lead driller on a routine boring job.","Air pressure and rotary speed gauges — read and report readings to a supervisor when drilling through common rock or concrete formations.","Drill bits and drill rods — select and attach correct components under guidance, adding rods as hole depth increases on a supervised crew.","Truck-mounted drilling equipment — assist in driving, leveling, and stabilizing the rig under direct crew supervision at a job site.","Earth cuttings and borehole dust — operate flushing and blowout equipment following standard procedures to keep holes clear during drilling.","Boring depth and alignment measurements — verify and record hole depths and positions using basic measuring tools under a lead driller's oversight.","Routine lubrication and minor part replacement — perform basic maintenance tasks on drilling machinery following a written checklist at the end of a shift.","Personal protective equipment and site hazard signs — recognize and follow safety protocols to protect oneself and co-workers on a drilling site.","Verbal instructions and crew communications — listen actively and confirm understanding of task assignments during pre-shift briefings on a drilling crew."]},"developing":{"label":"Developing","statements":["Rig stabilization controls and telescoping derricks — extend and lock components independently to level and align equipment on varied terrain without constant supervision.","Drilling speed and downward pressure settings — regulate and adjust parameters for different rock or concrete types based on observed bit performance during routine jobs.","Drill bit condition and rod inventory — evaluate wear and exchange bits or add rods as needed to maintain efficient hole progression on a mid-size boring project.","Air pressure and rotary speed calibration — adjust settings in real time to match soil and rock transitions encountered on a typical excavation assignment.","Borehole depth and alignment verification — confirm positions using measuring instruments and log results accurately in field records for quality assurance purposes.","Routine machine maintenance and drill bit build-up — perform scheduled upkeep, including bit restoration and lubrication, on a two- to three-machine crew without a supervisor present.","Equipment fault symptoms — monitor machine sounds, vibrations, and instrument readings to identify early signs of mechanical problems during an active drilling shift.","Flushing and dust-control systems — operate and troubleshoot cuttings removal equipment to maintain clean boreholes across multiple hole types and soil conditions.","Job site coordination — communicate schedule changes and equipment status to crew members and a foreman to keep a multi-rig project on pace.","Spreadsheet and word processing software — record daily production data and equipment logs using standard office suite tools for project documentation purposes."]},"proficient":{"label":"Proficient","statements":["Full rig positioning and alignment sequence — execute all stabilization, leveling, and derrick extension steps autonomously across varied and challenging site conditions.","Complex drilling parameter management — regulate air pressure, rotary speed, and penetration rate simultaneously while adapting to unpredictable subsurface formations on a large-scale project.","Drill bit and rod selection for non-standard formations — choose and configure appropriate tooling for hard rock, fractured strata, or reinforced concrete without supervisor input.","Machine performance diagnosis and troubleshooting — isolate mechanical root causes and implement corrective action on-site to minimize downtime on critical boring operations.","Preventive and corrective maintenance plans — build up and restore drill bits, replace high-wear components, and schedule lubrication cycles to extend equipment service life.","Borehole quality verification — assess depth, alignment, and casing integrity against project specifications and flag deviations before they affect downstream construction activities.","Multi-hazard site safety management — apply public safety and equipment-specific protocols to protect the crew and public during drilling near utilities or in confined areas.","Critical problem solving for unexpected subsurface conditions — evaluate drilling resistance, cuttings characteristics, and rig feedback to adjust methods in real time on a complex boring contract.","Mobile location-based services software — use GPS and positioning tools to confirm borehole coordinates and update site layout records during a precision drilling assignment.","Cross-trade coordination — collaborate with engineers, surveyors, and other trades to align drilling schedules and specifications with overall project milestones."]},"advanced":{"label":"Advanced","statements":["Drilling program strategy and rig deployment planning — design equipment selection criteria, hole sequencing, and crew assignments to optimize production across a multi-site contract portfolio.","Crew training and skills development — mentor entry-level and developing drillers in machine operation, safety procedures, and quality standards to build a high-performance field team.","Fleet maintenance standards and upgrade programs — establish preventive maintenance schedules, approve major equipment rebuilds, and evaluate new tooling technologies for organizational adoption.","Organizational safety culture and regulatory compliance — set site safety policies, conduct audits, and ensure all drilling operations meet OSHA and public safety requirements across all company projects.","Complex problem resolution at organizational scale — lead the diagnosis and correction of systemic equipment failures or recurring drilling quality issues affecting multiple active projects.","Performance metrics and quality control systems — design and implement production monitoring, depth-accuracy tracking, and quality control analysis frameworks used across the company's drilling operations.","Budget and resource management for drilling operations — forecast equipment, labor, and consumable costs, and control expenditures to deliver projects within approved financial parameters.","Client and stakeholder communication — represent the organization in technical discussions with engineers, project owners, and regulators to define scope, address concerns, and secure future work.","Equipment selection and procurement decisions — evaluate and recommend new drilling rigs, bits, and support technologies based on operational data and emerging industry standards.","Knowledge management and best-practice documentation — author and maintain standard operating procedures, training materials, and field guides that codify organizational expertise for the drilling workforce."]}}},"sources":{"onet":"v30.2 (CC BY 4.0)","crosswalk":"https://skillscrosswalk.com","generator":"LER.me"},"attribution":"© EBSCOed"}
