Mapping Seismic Data Workshop
This workshop covers the mapping of seismic interpretation. It works through interpretation quality and its effect on maps, well tie and horizon identification, picking consistency and loop closure, fault interpretation and mapping, time mapping and gridding, attribute and amplitude mapping, depth conversion within the mapping workflow, resolution and its limits on map detail, interpretation and map validation and the delivery of seismic derived maps.
Description
Seismic interpretation produces a horizon in time, and a long chain of further steps converts that into a structural map used for volumes and well planning. Each step introduces error: the horizon may be picked on the wrong event, the picking may be inconsistent between lines, the faults may be mapped with incorrect relationships, the gridding may add features and the depth conversion may distort the structure. A map that reaches a decision carries all of these.
This workshop covers the chain from interpretation to map. Interpretation quality and its effect on maps are established first. Well tie and horizon identification follow, covering the synthetic tie and the confirmation that the picked event is the intended horizon. Picking consistency and loop closure are then developed. Fault interpretation and mapping follow in detail. Time mapping and gridding are then addressed. Attribute and amplitude mapping follow. Depth conversion within the mapping workflow is then developed. Resolution and its limits on map detail follow. Interpretation and map validation are addressed. The workshop closes with delivery.
Loop closure is the basic internal check on an interpretation and it is often skipped. Following a horizon around a closed loop of lines or through a three dimensional volume should return to the starting value; if it does not, the interpretation has jumped events somewhere in the loop. Misclosures accumulate in complex areas and across faults, and an interpretation with open loops contains a step that will appear on the map as a structural feature. Checking closure systematically identifies where the pick needs review.
The synthetic tie establishes which event is the horizon and is frequently taken on trust. Generating a synthetic seismogram from the well's sonic and density logs, matching it to the seismic at the well and identifying the reflection corresponding to the formation top is what links the interpretation to the geology. A tie performed carelessly, or a horizon picked on the nearest strong event rather than the tied one, produces a map of something other than the intended horizon, and the error is systematic across the whole map.
Fault mapping errors change the compartment structure. Whether two faults intersect, which truncates which, whether a fault is continuous or segmented and where its tips lie all determine the fault block geometry that the structure map expresses. These relationships are interpreted from the seismic and are frequently ambiguous, and the interpretation chosen determines the trap configuration. Testing the fault interpretation for geometric consistency, and against the throws observed in wells, is a specific step.
Finally, map detail cannot exceed seismic resolution. A seismic volume with a dominant frequency of thirty hertz in rock with a velocity of three thousand metres per second has a vertical resolution of around twenty-five metres and a lateral resolution of a few hundred metres. A structure map from that volume contoured at a five metre interval, showing features a hundred metres across, is displaying detail the data cannot support. Calculating the resolution and choosing the contour interval accordingly is a short exercise that prevents a common form of over-interpretation.
By the end of this workshop, participants will be able to:
- Assess interpretation quality and its effect on the resulting map
- Perform well ties and confirm horizon identification
- Maintain picking consistency and check loop closure
- Interpret and map faults with consistent geometry
- Produce time maps and select gridding parameters
- Produce and calibrate attribute and amplitude maps
- Apply depth conversion within the mapping workflow
- Calculate seismic resolution and match map detail to it
- Validate interpretations and maps against wells and geology
- Deliver seismic derived maps with their limitations stated
The workshop works on seismic volumes and two dimensional grids with well control. Participants tie wells, interpret horizons and faults, check loop closure and produce maps. Interpretations are compared between participants on the same data to show interpretational variability. Maps are tested against wells withheld from the exercise.
