If you’re a field geologist using CorePlan’s free Client Portal, you probably have a routine: finish up on site, head back to camp, find a bit of Wi-Fi, log in, and work through the day’s Plods.

But here’s the thing - you don’t actually have to wait.

CorePlan’s mobile app lets you review and sign off Plods directly at the rig, even with zero internet connection. Your approvals sync automatically once you’re back in range.

Why waiting slows everything down

When approvals wait until the end of the day, so does progress. Contractors can’t finalise their records, project managers can’t see updated drilling data, and you’re left relying on memory to recall what you saw at the rig hours earlier.

If there’s an issue - like a measurement mismatch, an unclear interval, or a quality concern - catching it in the field means it’s solved on the spot. Catching it later from camp often means more back-and-forth, or worse, another trip out.

Approving Plods offline removes that bottleneck and keeps your workflow moving in real time.

How offline sign-off works

1. Open the app at the rig

Fire up the CorePlan mobile app while you’re on site. No signal needed because the app works entirely offline.

2. Review the Plod

You’ll see all the same details you normally would: metres drilled, shift times, sample intervals, downtime reasons, notes from the driller. Compare what’s recorded with what you’ve observed in the field.

3. Approve or flag issues

If something’s off, reject it and leave a comment right then and there - while the driller’s still beside the rig. They get feedback immediately, not hours later.

4. Let it sync automatically

Once you’re back in coverage - whether that’s camp, your vehicle, or the nearest signal patch - the app syncs your approvals automatically. No uploads, no remembering to send later.

What this looks like day-to-day

At the rig (offline):

Review Plod details.
Compare them against real conditions.
Approve or request changes.
Move onto your next task.

Back at camp (online):

Your approvals sync automatically.
Contractor sees updates in their system instantly.
Project records update in CorePlan.
And you’re done - no late-night admin session required.

Why this small shift matters

Offline approval isn’t just about saving time, though it does that. It’s about accuracy and context.

When you review data immediately, you remember the ground conditions, the sample quality, the specifics of what you just saw. That context makes your approvals more meaningful and your data more reliable for everyone who uses it, from project managers tracking progress to database teams maintaining QA/QC standards.

Common questions

What if I lose service before the sync?

No issue. Approvals are saved locally and sync automatically once connectivity returns, even if you’ve approved several Plods offline.

Can I view past Plods offline?

Yes, as long as you’ve opened the app recently while connected. The app stores recent data so you can access and review it without internet.

What if a driller updates a Plod I’ve already approved?

You’ll see the revised version after syncing and can re-approve or comment as usual.

The bottom line

You don’t need a Wi‑Fi connection to keep drilling moving. CorePlan’s mobile app lets you review and approve Plods at the rig, while details are still fresh.

It’s faster, more accurate, and built for the way geologists actually work in the field. The tools are already there - you just have to put them to use.
