Upstream Oil & Gas

Concept selection and front-end definition for onshore and offshore development concepts, gas processing, and LNG.

The front end of an oil and gas project is squeezed from both sides. Teams are pushed to reach sanction faster, and conventional studies only carry a few cases, none of which may be optimal.

Roebling holds the option space open. One model carries process, cost, and economics from first concept to a sanction-ready definition, in days, not months, with every number traced to a source anyone can audit.

“Upstream front-end work is selective omission, not false precision. You don’t need every process detail early — you need to know which ones don’t matter yet. What drives cost? What cascades if the reservoir is wrong? Nail the major levers, and you can run the scenarios that either advance the project or kill the marginal ones early.”

Previously

A new basis for front-end engineering

The full option space carried through concept selection, rather than the three cases the schedule allows.

Process, cost, and economics held on one basis, so a facility change moves capital intensity and NPV together.

Front-end definition completed before your estimating and project management teams are committed to a concept.

Assess (FEL-1)

Go or no-go, and which development concepts do we carry forward?

AACE Class 5

For teams screening development concepts before committing study budget.

Build and compare concepts across the whole option space; identify the cases worth carrying into Select.

Select (FEL-2 / Pre-FEED)

Which concept do we commit to, and at what capital intensity?

AACE Class 4

For teams converging on one concept.

Compare business cases and their sensitivities; the model refines as appraisal data and engineering definition come in.

Define (FEL-3 / FEED)

Can we sanction this, and what will it actually cost?

AACE Class 3

For teams heading into FID.

One concept, carried on the same basis into the sanction package, alongside the FEED engineering the stage demands.

Frequently Asked Questions about Roebling

We already run simulators, estimating tools, and internal cost databases. What is different?

Those are point tools: each solves one slice, and nothing brings the slices together. Roebling holds process, cost, schedule, and economics in one model, so the whole option space is screened and compared on a consistent basis, rather than the two or three cases where there was time to assemble by hand.

Our dominant uncertainty is subsurface. Where does Roebling help?

We stay out of the reservoir. Roebling models the surface facility and the concept economics, so for any range of subsurface outcomes you can screen development concepts quickly and see how capital intensity and NPV respond. The geology remains your call; the facility case that answers it is where we work.
