Case studies
Drilling, coal seam gas, tendering and LNG project controls: what I did, how, and what changed. Every figure comes from my CV or my 2025 Engineers Australia industry review.
- 51-well CSG drilling campaignCoal seam gas drilling: leading a 51-well coal bed methane campaign that cut rig moves from 3.27 days to 1How Inderpreet Singh led a two-year, 51-well coal bed methane drilling campaign for ONGC: 52,445 m drilled, rig move time cut 69%, 28.7 m/hr rate of penetration against a 17 m/hr benchmark, USD 0.6M OpEx saved.
- Drilling rig tenders & estimationTendering and estimation for drilling rig contracts: day rates, deviations and bid economicsHow Inderpreet Singh prepares drilling rig and pipeline tenders: SOW and BOQ review, pre-bid queries, day-rate estimates from rig performance data, deviations, and EBITDA, IRR and cash-flow inputs. Five bid packages totalling USD 82.9M.
- LNG service agreements & PMOProject controls, PMO and asset support for Shell's Brunei LNG and Oman LNG service agreementsHow Inderpreet Singh managed operational service agreements and asset support plans for Brunei LNG (USD 27.5M) and Oman LNG (USD 48.8M) at Shell: KPI reporting, Power BI dashboards saving 456 hours a year, and USD 50K recovered in invoice disputes.
- Rig recertification & HSERig recertification, inspection and HSE compliance on land drilling rigsHow Inderpreet Singh kept land drilling rigs compliant and fit for contract: CAT IV recertification of a 1400 HP rig, API RP 7G and DS-1 tubular inspection, DNV third-party inspection, root-cause risk assessment on a 750 HP rig, and ISO 9001/14001/45001 systems.
