We produce full calendar duration ranges rather than isolated drilling-time estimates. Outputs are structured as bounded scenarios (Low / Best / High, P10 / P50 / P90 equivalent), allowing clients to understand exposure before pricing, commitment, or board approval. The objective is not precision but defensible range visibility.

​Operational friction is separated from drilling physics. Interface constraints, access limitations, handling systems, crew coordination, and site logistics are explicitly represented so that programme complexity is visible rather than embedded within optimistic drilling rates.

​

​

Downtime is not applied as a generic percentage. We model downtime as a structured component of programme duration, reflecting ground behaviour, tool performance, handling cycles, and escalation mechanisms. This ensures that non-productive time is visible, reasoned, and proportionate to the conditions.

​Every output is traceable to defined assumptions. The modelling process is transparent and structured, allowing assumptions to be reviewed, challenged, and adjusted without destabilising the whole forecast. This enables constructive technical discussion rather than black-box outputs.

​

​When ground conditions deteriorate, productivity falls and downtime increases; together. Our modelling framework rejects independence assumptions and applies scenario-based escalation logic, ensuring that adverse conditions compound realistically rather than being averaged away.

​

All duration drivers; productivity, ground transitions, downtime triggers, and escalation thresholds are documented and auditable. Clients receive a structured assumption register so that duration logic can be clearly communicated to commercial teams, technical reviewers, and governance stakeholders.
