Introduction
Every Plod in CorePlan has a unique identifier made up of a rig ID, a date, and a shift code. Understanding this format helps you quickly identify which rig, date, and shift a Plod belongs to. Optional suffixes can also indicate shared Plods or duplicate entries.
The Plod number format
A Plod number follows this structure:
[rig ID]-[YYMMDD][shift]
For example: 1234-270614D
Each part of the number means the following:
1234 is the rig's internal CorePlan ID, not the rig name. This is assigned by CorePlan and may differ from any name used in your project.
270614 is the date in YYMMDD format: 14 June 2027.
D is the workshift code.
The three shift codes are:
Code | Shift |
D | Day |
M | Middle shift |
N | Night |
💡Note: The shift code M stands for Middle shift. CorePlan uses M (rather than A for Afternoon) so the three shifts sort in the correct order alphabetically: D, M, N.
Optional suffixes
Plod numbers can include one or two suffixes after the shift code.
-S: Shared Plod
A -S suffix is added when a Plod is shared between a drilling contractor and a mining client, and has been approved on the mining side.
1234-270614D-S
When the mining client approves the Plod, the rig ID also changes: the drilling contractor's rig ID is replaced by the mining client's rig ID. For example:
1234-270614D → 5678-270614D-S
This means the same Plod will appear under a different number once it reaches the mining account.
-2: Duplicate identifier
If a Plod is exported from one project and imported into another before being deleted from the original, the same Plod number already exists in CorePlan. To avoid a conflict, CorePlan adds a -2 suffix to the imported entry.
1234-270614D-2
Combined suffixes
Both suffixes can appear together when a shared Plod also has a duplicate identifier:
1234-270614D-S-2
Tips and best practices
A few things worth knowing when working with Plod numbers in practice:
When sharing Plod numbers with clients, use a placeholder rig ID like 1234 rather than the actual internal CorePlan ID to avoid confusion.
If you see a
-2on a Plod, check whether the original exists in another project and delete the copy you no longer need.
