Extraction","sector":"21","jobZone":2,"jobZoneInferred":false},"framework":{"version":"v.26.05","description":"","contextCovered":"This framework covers the inspection, maintenance, fluid control, repair, and safe operation of oil and gas derrick systems, from entry-level rig-floor tasks through organization-wide leadership of drilling operations.","levels":{"emerging":{"label":"Emerging","statements":["Derrick inspection basics — recognize visible flaws and surface defects under direct supervisor guidance before a derrick is raised on a drilling site.","Cleaning and oiling procedures — follow step-by-step protocols to clean and lubricate derrick components under close supervision on an active rig.","Crown block installation — assist in positioning and bolting crown blocks to derrick posts under the direction of an experienced operator.","Mud pump start-up — initiate pumps that circulate drilling mud through drill pipes following a written checklist on a supervised job site.","Drilling fluid properties — identify basic viscosity and weight readings on mud samples using hand-held instruments under trainer oversight.","Rig pump monitoring — listen to mud pumps at regular intervals and report unusual sounds or vibrations to a senior operator on shift.","Harness and climbing device use — don and adjust personal fall-arrest harnesses and platform climbing devices following safety protocols before ascending the derrick.","Basic hand tool use — select and apply wrenches, hammers, and other hand tools to minor pump and tank fittings under direct instruction on the rig floor.","Safety hazard recognition — identify common rig-site hazards such as slick surfaces, overhead loads, and pressurized lines when completing entry-level inspection rounds.","Equipment log entry — record inspection findings, fluid readings, and pump status in paper or electronic logs using word processing or spreadsheet software under supervision."]},"developing":{"label":"Developing","statements":["Pre-raise derrick inspection — conduct full visual and mechanical inspections of derrick structures before raising or lowering operations with minimal supervisor prompting.","Drilling fluid control — adjust viscosity and weight of drilling mud by adding materials and rechecking measurements to maintain target specifications during active drilling.","Pump and mud tank repair — diagnose and repair common faults in mud pumps and tank fittings, restoring normal operation with reduced oversight on a producing well site.","Crown block alignment — independently position and bolt crown blocks to derrick posts, verifying plumb and load ratings before drilling operations resume.","Mud circulation troubleshooting — identify loss-of-circulation events or pressure anomalies by cross-referencing pump gauges and pit volume readings during a drilling shift.","Derrick lubrication schedule — plan and carry out routine cleaning and oiling tasks on a recurring maintenance schedule to keep the derrick in safe working condition.","Harness and climbing device operation — position and align derrick elements at height using climbing devices and safety harnesses, adapting to weather or platform conditions.","Rig pump vibration analysis — evaluate pump vibration patterns against normal baselines and initiate corrective action before equipment damage occurs.","Verbal status reporting — communicate shift findings, fluid readings, and equipment status clearly to drillers and crew members during handover meetings on site.","Maintenance record management — update spreadsheet-based maintenance logs and generate routine inspection reports using company software after each completed task."]},"proficient":{"label":"Proficient","statements":["Full derrick inspection program — autonomously inspect all structural elements, connections, and load-bearing components of a derrick, ordering specialist inspections when deficiencies exceed field-repair scope.","Advanced fluid engineering — continuously optimize drilling fluid viscosity, weight, and chemical additives to address changing formation pressures and protect drill bit performance.","Complex pump system repair — diagnose and rebuild multi-stage pump assemblies, replace worn liners and seals, and return full mud-circulation systems to service without external assistance.","Non-routine crown block operations — manage crown block rigging and bolt-up on irregular or damaged derrick posts, applying engineering judgment to load distribution and structural integrity.","Integrated systems monitoring — simultaneously track pump pressures, pit volumes, mud properties, and derrick structural data to detect and resolve compounding rig problems during high-pressure drilling intervals.","Derrick erection and teardown coordination — direct the full sequence of raising or lowering a derrick, verifying each mechanical and safety checkpoint across the entire operation.","High-altitude element positioning — lead precise alignment of derrick components at crown level in adverse wind or weather conditions, applying depth perception and arm-hand steadiness skills to critical fits.","Root-cause problem solving — apply systematic troubleshooting to recurring mud system or pump failures, tracing faults to root causes and implementing permanent corrective measures.","Quality control verification — apply structured quality-control analysis to inspect welds, bolted joints, and fluid system integrity against API and company standards on completed rig assemblies.","Crew technical guidance — explain inspection methods, fluid control procedures, and repair techniques to newer operators during on-the-job training sessions on a working rig."]},"advanced":{"label":"Advanced","statements":["Derrick inspection program oversight — establish and enforce site-wide derrick inspection standards and ordering criteria, ensuring regulatory compliance across multiple rigs or a full drilling program.","Drilling fluid strategy — develop mud-program specifications for new wells based on formation data, well design, and cost targets, directing the derrick and mud-engineering team throughout execution.","Maintenance system design — design preventive-maintenance schedules and repair-priority frameworks for all pump, tank, and derrick equipment across a rig fleet, reducing unplanned downtime.","Capital equipment decisions — evaluate derrick condition assessments and repair-versus-replace trade-offs, making final recommendations to operations management on major equipment investments.","Workforce development — design and deliver structured training curricula covering inspection, fluid control, and derrick operations for apprentice and mid-level derrick operators across the organization.","Incident investigation leadership — lead root-cause investigations of rig equipment failures or near-miss events, producing formal reports with corrective actions presented to senior management.","Cross-functional hazard management — coordinate with drillers, safety officers, and well engineers to integrate derrick and mud-system risk controls into the overall well-operations risk framework.","Performance metrics and reporting — define key performance indicators for derrick and mud-system reliability, analyze trend data using spreadsheet tools, and report findings to operations leadership.","Regulatory and standards representation — represent the organization in discussions with regulatory bodies and industry working groups on derrick safety standards and equipment certification requirements.","Organizational culture of safety — model and champion cautiousness, integrity, and attention to detail as cultural norms, influencing derrick crew behavior and decision-making at every level of the operation."]}}},"sources":{"onet":"v30.2 (CC BY
