In engineering, we love simplicity. A clean, elegant solution that just works, especially in a messy and complex world, feels like magic. But hereâs the kicker: getting to that level of simplicity takes deep thinking, years of experience, and usually, a few coffee-fuelled debates with the team.
This is the essence of the KISS principle, âKeep It Simple, Stupidâ, originally coined by the U.S. Navy in the 1960s. It wasnât advocating for dumbing things down. it wasnât meant to insult anyoneâs intelligence. It was a reminder not to make things more complicated than they need to be.
But in oil and gas? Well⌠sometimes we miss the memo.
đ¨ When KISS Goes Off the Rails
Weâve all been there: you start with a nice, neat model. Life is good. But then it doesnât quite handle everything. So, we add a variable. Then an adjustment. Then a lookup table. Then three macros and a Monte Carlo simulation for good measure.
Before you know it, your âsimpleâ solution now requires a user manual, a troubleshooting guide, and possibly a dedicated team to maintain it.
Take production forecasting. A basic Decline Curve Analysis (DCA) can beat a full-blown reservoir model for short-term predictions with way less data, fewer assumptions, and about 1/10th the headache. But the moment DCA doesnât behave, we panic and start building the forecasting equivalent of Frankensteinâs monster.
And the irony: the more complexity we add, the more assumptions we introduce, most of which are based on âgut feelâ or whatever data we could scrape off a dusty spreadsheet from the last century.
This is how engineers accidentally create beautifully complex models that are less accurate, harder to explain, and way more expensive to maintain.
So Whereâs the Sweet Spot?
That, my friends, is the eternal question. Itâs not a formula, itâs a judgment call. And that judgment comes from a blend of:
- Technical depth: so you actually understand what matters (and what doesnât).,
- Experience: both the kind that teaches you what works, and the kind that teaches you what *definitely doesnât,*and
- Business sense: so the solution does what itâs meant to do, not just whatâs technically possible.
Sometimes, what looks like oversimplification is actually a strategic trade-off, or smart prioritisation as I was told once.
I recently shared a Inflow Performance Relationship (IPR) tool for CSG wells. Some might wonder âWhereâs the VLP curve? Whereâs the NODAL analysis?â
But hereâs the thing: we consciously decided to omit VLP for a reason. In CSG wells with dual flow paths and downhole separation, the assumption of mass conservation (which underpins NODAL) may not hold true. Adding complexity there would have introduced error, not removed it.
Adding complexity just to look smart? Thatâs not engineering, thatâs theatre.
Final Thoughts
The right level of simplicity doesnât come from ignoring complexity, it comes from understanding it deeply and then distilling it down to what matters most. KISS is not a shortcut. Itâs the outcome of thoughtful design, guided by expertise, collaboration, and practical business goals.
So the next time someone says âkeep it simpleâ donât just think âkeep it easy.â Think strategic. Think fit-for-purpose. And remember: true simplicity is hard-earned.
