Manage crew readiness, mobile-equipment hazards, jobsite incidents, and corrective work across field services and maintenance bases.
Oilfield and energy service companies move people and specialized equipment between customer locations, often under changing schedules and operating conditions. Pressure pumping, cementing, wireline, coiled tubing, well testing, and equipment servicing each introduce distinct hazards.
Dexur EHS organizes safety information around the service line, crew, job, and equipment package. Help dispatchers, field supervisors, technical specialists, and HSE managers identify unresolved requirements before mobilization and carry lessons from completed jobs into the next assignment.

A service company’s exposure begins before its personnel reach the wellsite.
Equipment must be prepared, loaded, transported, positioned, connected, operated, disconnected, and returned for maintenance. During that sequence, the crew may encounter conditions that differ from the original job scope.
A changed pressure requirement, substituted component, delayed start, or revised site layout can alter the risk. Safety records need to follow those changes rather than remain attached only to the initial job briefing.
OSHA’s well-servicing guidance identifies hazards associated with specialized service operations, including wireline, coiled tubing, and other intervention activities. OSHA: Oil and Gas Special Services
Follow the assignment through:
Job Preparation → Mobilization → Rig-Up → Service Execution → Rig-Down → Return to Base
For example, a pressure-component substitution may require technical approval before connection. A long delay may require reassessment of crew availability and travel plans. A leak discovered during rig-down may need to remain attached to the equipment record until repair and verification are complete.
Dexur EHS preserves the concern, responsible decision-maker, operating restriction, and follow-up evidence.
Record personnel injuries, equipment failures, pressure events, transport incidents, and near misses against the job and service performed.
Retain the activity underway when the event occurred. A connection failure during testing presents different investigation questions from a release during disassembly.
Service-specific examples include:
Structure checks around the equipment package and assigned work.
Review:
A pre-dispatch inspection should establish readiness for the planned assignment. The field review must then account for the actual site conditions and any changes in scope.
Organize the qualifications and evidence relevant to each role:
Distinguish attendance at a course from demonstrated competence, current authorization, and readiness for a particular job.
Assign findings to the service line, maintenance base, fleet team, technical authority, or field supervisor responsible for resolution.
Examples include:
Finding → Equipment or Job Restriction → Required Work → Responsible Owner → Verification → Release Decision
Keep restrictions visible when equipment transfers between crews or locations. Completion of a repair should be supported by the inspection or test appropriate to the defect.
Relevant categories include:
Record actual consequences separately from potential severity. A component failure discovered during testing may warrant wider equipment review even when nobody was injured.
Include:
Equipment identifiers are particularly important when units move between jobs. A defect recorded only against a location can become difficult to trace after demobilization.
Event → Job Preparation Review → Equipment History → Field Configuration → Work Execution → Contributing Causes → Corrective Actions
Questions may include:
The investigation should identify whether the problem originated in preparation, maintenance, transport, field execution, or handover.
Oilfield service companies may carry out well servicing, workshop maintenance, commercial transportation, construction, and specialized licensed activities. These functions do not all have the same regulatory requirements.

Establish applicability by activity and jurisdiction rather than assigning one checklist to every service job.
29 CFR 1910.147 excludes oil and gas well drilling and servicing from its scope. That exclusion should not automatically be extended to separate workshop or other maintenance activities covered by the standard.
Document the applicable requirements and task-appropriate methods for controlling electrical, mechanical, hydraulic, pneumatic, and pressure hazards. OSHA: Control of Hazardous Energy
A service unit can encounter different compliance requirements at the wellsite and after it returns to the maintenance base.
Where employees perform covered general-industry work involving respirable crystalline silica, 29 CFR 1910.1053 provides the applicable framework.
Assess exposure at transfer, loading, unloading, and other relevant points. Preserve the equipment configuration and operating conditions associated with monitoring and control evaluations. OSHA: General Industry Silica Standard
| Regulatory area | When it may be relevant | Information to organize |
|---|---|---|
| FMCSA motor-carrier requirements | Covered commercial motor vehicle operations. | Driver qualifications, hours-of-service records, inspections, and maintenance references. |
| DOT Hazardous Materials Regulations — 49 CFR Parts 171–180 | Covered offering, handling, and transportation of hazardous materials. | Classification, shipping documentation, packaging, and required employee training. |

FMCSA’s oilfield provisions contain specific eligibility conditions. The waiting-time provision in 49 CFR 395.1(d)(2) concerns qualifying specially constructed vehicles and drivers requiring extensive equipment-operation training.
Drivers transporting supplies such as sand or water do not automatically qualify. Work performed during a waiting period also affects its classification. Review the actual vehicle, driver role, and activity. FMCSA: Oilfield Waiting-Time Guidance
Maintain fatigue review alongside the applicable legal record. A permitted duty arrangement does not establish that an individual is fit for every subsequent task.
Personnel performing covered hazardous-material transportation functions require training appropriate to their responsibilities.
A general chemical-safety course does not replace all DOT training requirements. Identify who prepares shipments, loads materials, completes documentation, or performs other regulated functions. PHMSA: Training Requirements for Industry
Well logging using licensed radioactive materials carries specialized requirements. 10 CFR Part 39 addresses licensing and radiation-safety requirements for covered operations; Agreement State requirements and license conditions may govern the particular program.
Maintain the applicable source, personnel, equipment, and operating records under the responsible radiation-safety organization. 10 CFR Part 39: Well Logging Requirements
Dexur’s EHS record can reference related findings and corrective actions while the designated licensed program retains technical responsibility.
| Record | What it supports | What it does not establish alone |
|---|---|---|
| Training certificate | Completion of specified instruction. | Competence for every equipment configuration or service task. |
| Equipment inspection | Condition assessed at the stated time and scope. | Suitability for every pressure, fluid, or job requirement. |
| Customer approval | Acceptance under the customer’s stated process. | Compliance with every employer or regulatory obligation. |

| Driver duty record | Compliance information for the applicable driving rules. | Complete assessment of fatigue across field work and travel. |
| Post-job report | Findings from the completed assignment. | Resolution of defects before the next dispatch. |
Examples include:
Service operations require safety decisions at dispatch, on arrival, during execution, and before redeployment.
A unit that completed its last job may still carry a defect, maintenance requirement, or unresolved technical question. A qualified crew may be assigned unfamiliar equipment or a materially different scope.
Consider pressure, stored energy, chemical properties, vehicle movement, specialized hazards, and the ability to obtain assistance.
Review both the immediate job and the next use of the affected equipment.

| Equipment Defect Recurrence | Defects returning after repair or appearing across similar units. | Identify maintenance, specification, or equipment-selection problems. |
| Verified Corrective Action Closure | Timeliness, supporting evidence, overdue restrictions, and effectiveness. | Confirm that findings are resolved before equipment or personnel face the same hazard again. |
Use job counts, operating hours, trips, or other relevant activity measures where reliable data are available.
Compare service lines while retaining their different exposures.
Review:
See which assignments have unresolved equipment, competence, or technical requirements.
Identify recurring issues that require changes to preparation, staffing, maintenance, or equipment specification.
Review restrictions relevant to mobilization.
Coordinate vehicle status, load requirements, driver readiness, and unresolved findings with the responsible operational teams.
Access the assigned scope, equipment identifiers, job hazards, changes, and current restrictions.
Document when actual conditions require a revised plan or escalation to technical support.
See defects reported in the field and the service conditions under which they occurred.
Confirm the required preparation, repair, inspection, and release documentation before equipment returns to the dispatch pool.

Follow-through
This structure retains the connection between mobile equipment, personnel, and successive assignments.
Oilfield service information can become fragmented between field reports, dispatch records, maintenance systems, and customer documentation.
Dexur EHS preserves the safety finding and its follow-up as crews and equipment move between locations.
Attach defects and restrictions to identifiable components and units so the history remains available after demobilization.
Record revised pressures, materials, equipment arrangements, and task requirements before they are lost in informal communications.
Review instruction, competence, authorization, and site-specific preparation as related but distinct requirements.
Provide maintenance personnel with the operating conditions and evidence needed to investigate recurring failures.
Maintain visibility into the driving and journey risks surrounding field assignments.
Reference transportation, radiation, explosives, or other applicable requirements while retaining the designated technical owners.
Require evidence appropriate to the finding before releasing equipment for another assignment or repeating the affected task.
Bring crew-readiness records, mobile-equipment inspections, field incidents, exposure assessments, and corrective work into one service safety record.
