Artificial lift and production optimization, from a single problem well to a whole asset.
Production optimization means getting the most from a well by tuning flow rate, operating envelope and equipment, while keeping cost, safety and ESG compliance in view. Dr. Chokshi has done this for national oil companies, majors, independents and service companies worldwide, in conventional and unconventional assets.
How an engagement works
- Analyze your wells to find the right lift method and where the uplift is.
- Design the lift system or the change to it.
- Optimize flow rate and operating parameters across wells and equipment.
- Train your staff so the gains stay.
What I can do for you
Unconventional well optimization
- Injection-gas optimization for gas-lifted unconventional wells, including algorithms to find injection points (single and multi-point).
- Dynamic nodal analysis using months of real-time data.
- Prototypes in Excel/Python that drive Petroleum Experts’ Prosper through OpenServer, running hundreds of simulations to match surface and downhole measurements.
- Gap analysis of machine-learning and AI models built by data-science teams for artificial lift.
- Review of best practices in conventional and unconventional production.
Real-time surveillance and digital oilfield
- Pilot concept studies, for example offshore gas-lift optimization.
- “Well health” algorithms and measuring the effectiveness of interventions.
- Virtual flow meters combining ML with physics-based models; water-cut determination from downhole and surface gauges.
- ESP failure prediction; production and injection choke management; flowline analysis.
- Specifications for ground-up artificial lift and production optimization platforms: nodal algorithms (black-oil PVT, correlations and mechanistic models), ESP/PCP/gas-lift real-time analysis within equipment envelopes, and field tracking from well to enterprise level.
Advisory and strategy
- Advising multidisciplinary teams, up to C-level, on artificial lift planning and operations for onshore developments.
- Bespoke workshops, in-person or remote, including machine-learning approaches.
- Start-up services: use-case definition across flow assurance, well integrity and lift optimization; multi-year strategic plans for investors; client scoping.
- Analysis of state-published well data to find gas-lift efficiency and tax-saving opportunities.
- Review of ways to lower the carbon footprint of production operations, with artificial lift and deliquification use cases.
What you get
Increased production · Lower costs · Improved safety · Regulatory compliance
