Open-Hole Mini-Frac

The problem

Once casing is set, you measure through perforations or ports. Open-hole windows are the chance to see formation response directly — if isolation and hole condition allow a clean injection.

How we approach it

We assess hole condition, straddle or packer options, and injection limits with your drilling / completions team. The goal is a usable pressure signature without jeopardizing the wellbore. Timing against the drilling schedule is part of the plan, not an afterthought.

Typical deliverables

Questions operators ask

When is open-hole preferred?

When pre-casing stress is critical to landing zone or casing design decisions and hole conditions support isolation.

What if hole condition is poor?

We say so early. A compromised open-hole test wastes a critical-path window — cased-hole options may be the honest path.
