What are the duties of a toolpusher in drilling projects?

I. Core Responsibilities — Toolpusher

Rig-based operations leader for the drilling contractor, accountable for safe, compliant, and efficient execution of the drilling program on tour.

• I.1 — Operational leadership: Direct and coordinate daily drilling activities (spud, connections, tripping, BHA handling, casing/tubing running, BOP tests, cementing support) in line with the approved drilling program and contractor procedures.
• I.2 — HSE governance: Lead toolbox talks, JSAs, and PTW; enforce LOTO, DROPS controls, lifting standards, confined-space and hot-work controls; maintain emergency response readiness and conduct drills.
• I.3 — Well control assurance: Ensure well control equipment integrity and certification (BOP, choke manifold, accumulators), pressure testing, function tests, and crew competency; verify kill sheets and strip/kill procedures are current.
• I.4 — Execution discipline: Plan and brief critical operations; set and monitor drilling parameters within the safe operating window; manage tripping speeds, hole cleaning practices, and ECD control per program limits.
• I.5 — Crew supervision and development: Supervise drillers, assistant drillers, derrickmen, floorhands, and utility crews; schedule tours; coach to competence standards; conduct performance reviews and mentoring.
• I.6 — Equipment readiness: Oversee maintenance with mechanic/electrician; verify CMMS work orders, inspections, and certifications (lifting gear, pressure systems); approve equipment isolations and reinstatements.
• I.7 — Materials and logistics: Plan and call-off bulk materials and consumables (mud, cement, fuel, water, tubulars, bits, chemicals); manage inventory, rack storage, and loadouts/backloads with shore base.
• I.8 — Quality and compliance: Enforce procedures for BHA handling, torque-turn monitoring for casing, make-up/torque control, dope standards, thread inspection, and solids control optimization; oversee third-party service execution on the rig floor.
• I.9 — Reporting and KPI tracking: Approve IADC tour sheets, contractor daily reports, downtime/NPT coding, HSE observations, maintenance logs, and certification registers; communicate shift handovers with clear status and next steps.
• I.10 — Cost and time stewardship: Control contractor spread rate exposure via efficient operations, minimize NPT and flat time, optimize consumables use, manage overtime, and propose improvements.
• I.11 — Stakeholder interface: Coordinate plans and constraints with the operator’s company representative and third-party supervisors; escalate risks early and propose mitigations.
• I.12 — Incident control: Lead or support incident command on the rig during events within delegated authority; secure site, preserve evidence, and participate in investigations and corrective actions.

VII. Key KPIs and Useful Formulas

• VII.2 — Rate of Penetration (ROP): \( \text{ROP} = \dfrac{\text{Footage Drilled (ft)}}{\text{On-bottom Time (hr)}} \)
• VII.3 — Utilization: \( \text{Utilization} = \dfrac{\text{Productive Time}}{\text{Total Time}} \times 100 \)
• VII.4 — Equivalent Circulating Density (approx.): \( \text{ECD (ppg)} \approx \text{MW (ppg)} + \dfrac{\Delta P_{\text{annulus}}}{0.052 \times \text{TVD}} \) — manage via flow rate, rheology, and annular restrictions to stay within the pore–fracture window.
• VII.5 — Cost per foot (contractor lens): \( \text{CPF} = \dfrac{\text{Spread Rate} \times \text{Time}}{\text{Footage}} \) — indirectly influenced by minimizing flat time and NPT.
