Workover Programme Audit
Structured diagnostic on a workover programme that has plateaued, blown budget, or under-delivered — with an integer-programme model of the fleet capacity.
The problem you have
Your annual workover programme is running below target. The rigs are working — but you are delivering fewer interventions than the year before, NPT is creeping up, the standard sequence keeps producing the same delays, and your team’s diagnosis is “we need another rig.” You are not sure whether that is true, or whether the existing fleet has unrealised capacity that mix-rebalancing and operational re-engineering can unlock.
This is the kind of question I have spent the last two years rebuilding the workover programme around at one of the world’s largest mature giant fields — delivering material year-on-year throughput uplift at constant rig count, with substantial incremental oil-recovery contribution and significant CAPEX/OPEX savings.
What you get
A structured operational diagnostic with three deliverables:
- Workover throughput model — an integer-programme solver (parameter-driven by your fleet size, NPT profile, and category mix) that quantifies the maximum annual delivery your fleet can sustain, and which constraints are actually binding.
- NPT root-cause map — a categorised analysis of where time is actually being lost (rig moves, equipment, planning, contractor handovers) with a priority-ranked intervention list.
- Programme recommendation memo — 8–12 pages, written for an Asset Manager / Wells Manager audience. Specific, dated, with named owners and quantified expected uplift.
Price: £8,500 – £14,500 fixed depending on fleet size and data volume. 30-day turnaround. Reference engagements and methodology worked examples available under non-disclosure on request.
What this is not
- Not a software deliverable. You receive a model and a memo, not a SaaS product. If you want the model embedded in your planning system, that is a separate engagement.
- Not a contractor-performance review. Confidential vendor data is out of scope.
- Not a replacement for your internal continuous-improvement function. This is the outside diagnostic that re-anchors the conversation, not the year-long execution.
Process
- 30-min discovery call. You describe the programme, the throughput history, what data is available.
- Data scope agreement. We agree what gets shared, under what NDA, and in what format. Anonymised dataset preferred; full dataset under NDA also workable.
- Two-week analysis. I build the model and the NPT analysis, reviewing intermediate findings with your team weekly.
- Read-out. 2-hour workshop with your Wells / Asset team; written memo follows within 5 working days.
Frequently asked
Do you need access to our confidential data? You can either share anonymised data (preferred — same standard I apply to my own published case study) or share full data under NDA. Either works for the analysis.
Will you publish anything from our engagement? No. Every engagement is strictly confidential. The client identity, dataset, and specific findings remain confidential indefinitely. Generic methodology descriptions may be re-used in future work, but nothing tied to your engagement, in any form, will be published.
What if our fleet is mostly drilling rigs, not pure workover rigs? The model handles mixed-mode fleets. I will adapt the constraint formulation to your operational reality on the scoping call.
What if we don’t have clean data? Common situation. The first week of the engagement includes data-quality remediation as standard. If the data is irrecoverable, I will tell you on the discovery call and we will not start.
Can you do this work for an operator who competes with BECL / BP / CNPC? Conflict-of-interest decision case by case. Operators outside the Mesopotamian Basin and outside BP / CNPC JV footprint are typically clear.
