About this ebook

Three years after Deep Steam's data wall went green across six countries, Rani Kusuma should be celebrating. Instead, standing at a champagne-soaked ribbon-cutting in Iceland, she finds herself asking the one question her own board doesn't want raised: are these fields behaving strangely — or were they never really separate fields at all?

When the Commission dismisses her connectivity hypothesis as correlation without causation, Rani has to build a case good enough to survive being ignored by exactly the people whose job is to listen. Backed by a hydrogeologist who flags the first real anomaly, a modeler chasing a predictive breakthrough, and a sustainability analyst nobody else has time for, Rani closes in on an answer no single field can provide — while, on three continents at once, the ground keeps making her argument for her.

The Reservoir is Book Three of the Heat Below Series, the technothriller saga proving that the world's geothermal fields may never have been separate systems at all.

About the author

Andi Anriansyah is a senior subsurface professional based in Jakarta, Indonesia, with more than seventeen years of experience across oil and gas, mining, and infrastructure projects. His technical career spans reservoir and petrophysical evaluation, resource and reserves estimation, nickel exploration, and geotechnical ground-risk support on major infrastructure work, including the geological oversight of a hydropower dam foundation in North Sumatra. He holds a degree in Geological Engineering from Institut Teknologi Bandung (ITB).

The Reservoir draws directly on that career, on the particular, hard-won respect a subsurface engineer develops for a reservoir that refuses to behave exactly as its model predicts. The gap between what a well log tells you and what the ground is actually doing has been, for the author, both a professional preoccupation and the seed of an entire series.

The Reservoir is Book Three of the Heat Below Series, part of a wider Geothermal Universe. The author also writes The Abyss and The Deep Vein series.
