Complex Drilling Programs
Experienced crews, disciplined execution, and regional support.
Some drilling programs demand more than equipment on site. They require early planning, the right method, experienced crews, clear safety controls, and the ability to adjust as conditions change.
Project Conditions
Coordinated support for demanding drilling programs.
Some programs bring difficult access, complex ground, strict safety requirements, tight production windows, technical uncertainty, or multiple drilling methods across regions.
Boart Longyear brings the planning, crews, equipment, and field support needed to manage those demands as one coordinated program.
Complex ground conditions
Ground conditions are uncertain, variable, or difficult to predict.
Safety-sensitive work
The work takes place in active operations or environments with strict safety controls.
Multi-method programs
The project may require more than one drilling method or technical approach.
High consequence execution
Delays, rework, poor recovery, or inconsistent execution can affect production, schedules, and critical project decisions.
HOW WE SUPPORT EXECUTION
Experience and field judgment applied across changing conditions.
Boart Longyear brings experienced crews, multiple drilling methods, disciplined supervision, and regional support to work shaped by complex ground, safety requirements, tight operating windows, or costly downtime.
Complex geology or access constraints
Ground conditions, access, weather, depth, and operating constraints can all change how a program must be planned and executed.
Boart Longyear brings method experience and field judgment to adjust the approach as conditions change.
Programs requiring multiple drilling methods
Some programs require more than one drilling method across a site or project lifecycle. Boart Longyear’s capability spans surface, underground, production, Sonic, directional, water, and specialized applications, allowing the approach to change with the work.
Production-critical drilling
In active operations, drilling delays can affect production flow, access, and downstream schedules. Boart Longyear supports these programs through coordinated planning, equipment readiness, and consistent field execution.
Projects requiring experienced supervision and field judgment
When conditions change, crews need more than a work plan. They need supervisors and drillers who understand what is happening in the ground, on the rig, and across the site.
Boart Longyear teams bring together experienced crews, supervisors, technical specialists, maintenance support, and regional operations leadership.
Safety-sensitive operations
Safety-sensitive drilling depends on preparation before the shift, clear controls during the work, and consistent supervision throughout the program. Boart Longyear supports that discipline through risk assessment, hazard recognition, and established operating procedures.
Regional execution backed by broader experience
Regional teams bring local operating knowledge and field response. They can also draw on broader fleet experience, technical support, and established operating systems when the work demands it.
How We Operate
Execution starts before the rig is mobilized.
Reliable drilling performance starts with how the work is planned, staffed, equipped, and controlled before the first shift begins.
-
Understand the project conditions
Review the operating environment, ground conditions, access, safety requirements, schedule, and project objectives.
-
Select the right method and equipment
Match the drilling method, rig, tooling, support equipment, and crew requirements to the work.
-
Mobilize crews and support systems
Align crews, equipment, maintenance, safety systems, logistics, and regional support before work begins.
-
Execute with safety and operational discipline
Carry the plan into the field through supervision, communication, hazard controls, and consistent work practices.
-
Capture outcomes and field learning
Use project results, field observations, safety learning, and performance data to strengthen future planning and execution.
1 What Reduces Risk
Experience across methods, regions, and operating conditions
Ground conditions, access, schedules, and production demands can change quickly. Boart Longyear brings experienced crews, structured planning, and field judgment to support safe, controlled execution as conditions change.
Experience & Capability
Experience across methods, regions, and operating conditions.
Boart Longyear brings experience across surface, underground, production, Sonic, directional, water, and specialized drilling applications. Regional teams can also draw on broader technical, maintenance, and operating knowledge as project needs change.
Since 1890
More than a century of drilling experience.
Surface and underground capability
Drilling support across exploration, production, and active mine environments.
Advanced drilling methods
Sonic, directional, and specialized drilling applications.
Regional operating teams
Field execution supported by regional knowledge and broader operating experience.
Safety-led execution
Risk management, field controls, training, and operating discipline.
Technical support

Safety / ESG / Discipline
Operational discipline starts with safety.
Safety is part of how complex drilling work is planned, supervised, and executed. Boart Longyear’s approach includes field-based risk assessment, hazard recognition, pre-shift preparation, experienced supervision, incident learning, and consistent operating procedures.
Environmental, water, community, and compliance requirements are addressed through the same disciplined approach—aligned to the site, the region, and the work being performed.
Safety systems and field controls
Risk controls built into planning and daily execution.
Risk assessment and pre-shift discipline
Hazards, controls, and responsibilities reviewed before work starts.
Experienced supervision
Field leaders who understand the work, the conditions, and the decisions required on site.
Environmental and community responsibility
Environmental and community requirements addressed through planning, communication, and site-specific controls.
Consistent operating procedures
Work supported by established procedures, training, and supervision.

Winter Coring in Canada
- Region
- Canada
- Challenge
- Complete a winter coring program across two mine sites while meeting a minimum 90% core recovery requirement.
- Boart Longyear approach
- Our experienced crews coordinated a five-rig program to complete 218 holes through demanding winter conditions.
- Outcome / proof point
- 98.39% average core recovery, zero re-drills, and zero injuries across approximately 18,000 m of drilling.
