Subsurface Risk Is a Business Decision: Strategic Capital Discipline in Upstream O&G

Many upstream oil and gas organizations assume that because a reservoir has been modeled, its geological uncertainty has been managed [2]. In reality, a reservoir simulation model is merely a structured hypothesis, not subsurface reality itself. In this deep-dive video, we explore the core frameworks from Andi Anriansyah’s book "Subsurface Risk Is a Business Decision: From Reservoir Understanding to Strategic Capital Discipline" [1]. We unpack the structural contradiction at the heart of energy development: organizations make their largest, most irreversible capital commitments at the exact moment when geological understanding is at its absolute lowest. 💡 Key Takeaway: "The reservoir does not know your development plan or monthly targets—it obeys physics [20, 21]. Operational decisions that chase short-term production plateau at the expense of reservoir limits ultimately destroy long-term ultimate recovery". 💬 DISCUSSION QUESTION: How does your organization handle geological uncertainty at the FID stage? Are capital committees evaluating full Capital Exposure Maps or relying solely on deterministic P50 forecasts? Share your thoughts in the comments below!
