Accuracy at Speed: Why Precision Matters in Faster Reservoir Simulation

Imagine an engineer awaiting the results of a critical reservoir simulation before making a multi-million-dollar field development decision. In the past, this process might have taken days or even weeks. Today, advances in high-performance computing (HPC) are transforming this scenario. Simulation speed has become a strategic asset in oil and gas, enabling faster decision cycles and significant cost savings.

But speed alone is not enough. As one of my former colleagues put it, "You're not fast, you're just wrong fast." That line stuck with me. In today’s landscape, where every field decision involves complex subsurface conditions, speed is critical, but accuracy is non-negotiable.

We’ve all seen what happens when simulation shortcuts lead to lower recovery, unexpected water breakthrough, or underperforming wells. And here’s the thing: Missing barrels don’t show up in ‘good enough’ solutions.

Why Speed of Simulation Matters

Drilling a single well can cost tens of millions of dollars, so reducing uncertainty even slightly can save tremendous expense. Reservoir simulations guide crucial decisions like well placement, production strategies, and field development plans.

It is also an iterative process: history-matching to past production, forecasting future performance under various schemes, and optimizing development plans. If each simulation run takes days, teams may only evaluate a handful of scenarios. But if runs take hours or minutes, they can examine dozens or hundreds of cases. This breadth of evaluation leads to more robust plans and helps avoid costly mistakes.

From a business perspective, faster simulations contribute to better economics. Projects can be evaluated and sanctioned sooner. Conversely, potential failures or uneconomic scenarios can be identified early, before sunk costs mount.
