On the 2019 coal bed methane campaign we reached 28.7 m/hr against a 17 m/hr benchmark. This is a simple simulation, not field data: too little weight and you’re polishing the bottom; too much and the bit balls up.
Hold the brake to slack off weight onto the bit. Find the rate, then hold it.

Office-based roles in commercial and business development, contracts and procurement for rigs and well services, tendering, and project controls or PMO, across drilling, completions, coal seam gas (CSG) and LNG, in Brisbane or elsewhere in Queensland.
Yes. He is an Australian permanent resident (subclass 189), so no visa sponsorship is needed. He holds a White Card and lives in Brisbane.
From 2019 to 2021 he led a coal bed methane drilling campaign for ONGC in India across 51 wells and 52,445 metres. Rig move time fell from about 3.27 days to 1, rate of penetration reached 28.7 m/hr against a 17 m/hr benchmark, and the campaign saved USD 0.6M in OpEx within its two-year timeline.
Read the case studyAs Deputy Manager – Tendering & Estimation at Essar (2019–23) he developed bid packages for two 90 T drilling rigs (USD 22M for both), a 1000 HP rig (USD 19M), a 1400 HP rig (USD 18M), a 70 km pipeline (USD 11.9M) and a 614-person camp (USD 12M), refined day-rate estimates from rig performance data, and supplied EBITDA and IRR inputs for bids.
Read the case studyAt Shell (2023–26) he managed operational service agreements and asset support plans for Brunei LNG and Oman LNG: KPI reporting, WBS, forecasting, contract scope changes and invoice disputes. His Power BI dashboards saved 456 man-hours a year.
