Case studies

Illustrative scenarios showing how we would approach common challenges for industrial operators.

01

Cyber securitySCADA

Legacy system cyber security hardening

The challenge

An industrial facility runs critical SCADA systems on unpatched Windows XP and Server 2003. The systems were designed to be isolated from other networks, but operations now need remote access, which creates serious cyber exposure.

What it aims to achieve

Safe remote access to legacy control systems, a clear upgrade path the facility can fund in stages, and a security posture that is checked continuously rather than once.

Our approach

  1. Assessment

    • Inventory of PLCs, RTUs, servers, software versions and network architecture
    • Stakeholder interviews to find vulnerabilities and operational pain points

  2. Tiered hardening plan

    • Foundational options: network segmentation and operating-system upgrades
    • Transformational options: a new SCADA platform and secure mobile access

  3. Phased implementation

    • Firewalls and a DMZ to separate IT from OT networks
    • Server virtualization for fault tolerance
    • High-availability architecture

  4. Continuous protection

    • Ongoing vulnerability monitoring and patch management
    • Periodic security posture assessments

SCADADigital twin

Sour gas processing plant optimization

The challenge

A sour gas plant using amine sweetening on a low-H2S field faces excessive downtime, high amine consumption and inconsistent sales gas specifications.

What it aims to achieve

More runtime, lower amine and other input costs, and sales gas that stays on specification, without compromising the independence of safety systems.

Our approach

  1. Systems review

    • Review with operators and engineers
    • Sweetening design specifications compared with real operating conditions
    • Outdated hardware and software and unprotected system access identified

  2. Digital twin

    • A model matched to actual operating conditions, then tested
    • Downtime scenarios, amine consumption and sales gas specifications explored
    • Costs and timeline confirmed before any change to the plant

  3. SCADA modernization

    • Updated SCADA installed and tested
    • Heat, pressure, gas flow, amine circulation and sales gas specifications monitored in real time

  4. Closed-loop optimization

    • Gas and amine parameters adjusted automatically to keep sweetening on specification
    • Safety systems remain independent; operators stay in the loop

Automated joint-venture accounting

The challenge

An energy company relies on a “detect and correct” approach to joint-venture accounting. Accountants spend about half their time on manual data entry and after-the-fact reconciliation, and data spread across JV billing, ERP and spreadsheets leaves a 30-day blind spot.

What it aims to achieve

Accountants freed from manual entry, problems caught before month-end rather than after, and budget overruns visible early enough to act on.

Our approach

  1. Data integration hub

    • JV billing statements, ERP budgets and AFEs, and existing spreadsheets connected in one place
    • Manual re-keying between systems removed

  2. Automated variance analysis

    • Every line item checked continuously against internal rules
    • Green: verified · Yellow: variance flagged · Red: critical alert with a dispute drafted automatically

  3. Engineering alignment

    • Financial data cross-checked with operational status
    • Mismatches surfaced, for example maintenance costs on shut-in wells
    • Actual costs compared with approved AFEs and asset runtime

  4. Cash-flow forecasting and scenarios

    • Six-month forecast from confirmed payables, pending joint-interest billings and accruals
    • What-if modelling for commodity prices and AFE overruns, before costs are posted
