What this practice does — and why it matters.
Upstream oil and gas remains the backbone of global energy supply, yet the operating environment has never been more complex. Capital discipline, ESG scrutiny and volatile commodity cycles demand a new class of advisory partner — one that combines deep operational experience with sharp commercial judgement.
Chargeman brings four decades of hands-on upstream leadership across exploration, appraisal, development and production. We help operators optimise recovery, extend field life, and structure investment decisions that stand up to boardroom and investor scrutiny.
From single-asset optimisation to multi-basin portfolio strategy, our engagements are executive-led, data-driven, and grounded in what actually works in the field.

FAQs
Common questions.
How is a typical upstream oil & gas engagement structured?+
We begin with a two-to-three week diagnostic, followed by a strategy sprint and, where required, an implementation phase that can run from three to eighteen months depending on scope.
Who leads the engagement from Chargeman's side?+
Every engagement is personally led by PANKAJ MANCHANDA, Founder & CEO, supported by a curated bench of specialists drawn from our global network of operators, engineers and commercial advisors.
Do you work with international or India-only clients?+
Both. We serve energy majors, utilities, sovereign entities and private capital across India, the Middle East, Africa, South-East Asia and Europe.
How do you price your work?+
We work on fixed-scope, retainer, and success-linked models. Fees are agreed transparently at the outset, tied to milestones rather than time-and-materials whenever possible.
Can you integrate with our existing consultants or EPC partners?+
Yes. We routinely act as owner's advisor alongside global engineering firms, financial advisors and legal counsel — bringing sector depth and executive perspective.
How do you handle confidentiality?+
All engagements are governed by robust NDAs, segregated data rooms and strict information-barrier protocols. Confidentiality is fundamental to how we operate.
