Integrated Subsurface Mapping Workshop
This workshop runs a complete subsurface mapping exercise on one field. It works through data assembly and review, correlation and framework construction, structural and fault mapping, thickness mapping, facies and property mapping, net pay mapping, volume calculation, internal consistency checking, uncertainty assessment and the presentation of a complete mapped field with its volumes.
Description
Mapping is taught by technique and practised as a set. A field requires a correlation framework, structure maps on several horizons, fault maps, thickness maps, facies and property maps and net pay maps, all of which have to be consistent with each other and with the data, and which together produce the volume. This workshop runs that complete exercise on one data set from start to finish, including the consistency checks and the volume reconciliation that are usually omitted.
The workshop is structured as a project. Data assembly and review are established first. Correlation and framework construction follow, producing the stratigraphic skeleton everything else is built on. Structural and fault mapping is then developed. Thickness mapping follows. Facies and property mapping are then addressed. Net pay mapping follows. Volume calculation is then developed, by two independent methods. Internal consistency checking follows, covering the checks across the whole map set. Uncertainty assessment is addressed, covering alternative maps and their volume consequences. The workshop closes with the presentation of a complete mapped field.
The correlation decides everything downstream, so it is settled first and revisited. The framework determines which intervals are mapped, how thick they are, what connects to what and therefore the volume. Participants frequently find that their initial correlation needs revision once the thickness maps reveal patterns that do not make geological sense, which is exactly the feedback loop the workshop is designed to produce. Settling the framework and then testing it against the mapped products is the professional practice.
Consistency across a map set is what makes it usable and is rarely checked. The thickness between two horizons must equal the difference between their structure maps; net pay cannot exceed net sand; net sand cannot exceed gross thickness; property maps must lie within the range of the data. A map set that violates these contains an error and will produce a volume that cannot be reconciled. Checking the set as a whole, rather than each map individually, is the step that finds them.
Volume calculated twice is volume you can defend. A grid based calculation and an area depth curve calculation with average properties should agree. When participants calculate both for the first time they routinely disagree, and the exercise of finding out why teaches more about volumetric calculation than any amount of explanation. The discrepancies are almost always a specific identifiable cause, and finding them builds the habit of checking.
Finally, the mapped field has to be presented as a whole. The deliverable is not fifteen maps but a coherent description: this is the field, this is its structure, these are the reservoir intervals and their properties, this is the volume with its range, these are the main uncertainties and this is what would reduce them. Assembling that from a set of maps, and presenting it to a panel that asks where the numbers came from, is the final exercise.
By the end of this workshop, participants will be able to:
- Assemble and review a field mapping data set
- Establish a correlation framework and test it against mapped products
- Produce structural and fault maps on multiple horizons
- Produce thickness maps consistent with the structure maps
- Produce facies and property maps with geological trends
- Produce net pay maps
- Calculate volumes by two independent methods and reconcile them
- Check internal consistency across a complete map set
- Assess uncertainty through alternative maps
- Present a complete mapped field with its volumes and uncertainties
The workshop is a complete mapping exercise on one field data set, worked through from data to volume. Participants produce the full map set, run consistency checks, calculate volumes twice and reconcile them, and build alternative maps for the main uncertainties. Each team presents the mapped field and its volumes to a panel. Wells withheld from the exercise are revealed at the end.
