Inline 306: the legacy tomographic velocity model over the KPSDM migrated with it, nothing resolved in the snow zone

Inline 306: the 16 Hz macro TSL-FWI velocity model, broad structure returning and horizons flattening below the unconformity

Inline 306: the 45 Hz macro TSL-FWI velocity model, the snow zone opening up and clinoforms beginning to show

Inline 306: the 45 Hz targeted TSL-FWI velocity model, clinoforms resolved in the migration and in the velocity model itself

1 / 4Legacy model

Inline 306 — TSL-FWI velocity over the KPSDM migrated with that model, from the legacy model through to the 45 Hz targeted update.

What TSL-FWI can do

Three projects where the story is the method rather than the prospect — a target moved 650 ft and proved blind at the well, a model built from no starting model at all, and elastic salt that acoustic inversion cannot recover.

Highlander 2

Challenge · Blind tie · 650 ft

Extracting a velocity update to fix a 650ft pull up between two wells 2 miles apart

Open the case page

RTM through the Austin Chalk interval on the starting model — at Highlander 2 the chalk sits 650 ft above where the well found it, and the reflectors break up between the wells

The same interval on the final TSL-FWI model — an event arrives at the pick at both wells, continuous across the gap, with the 650 ft move down at Highlander 2 marked

1 / 2Starting model

Austin Chalk target interval, 26–30 kft — RTM on the starting model and on the final TSL-FWI model, with the 650 ft move down at Highlander 2 marked.

Alaminos Canyon crossline 414 — T3, continuity restored under the salt and deep compacted sediment resolved

Crossline 414 Vp — M0's compaction trend through T2 to T3, with continuity restored under the salt.

The enabler · XWAI

What makes these workflows possible

Behind every defined prospect is XWAI — S-Cube's AI copilot built into the X-Wave platform. It drives the advanced inversion workflows that turn difficult data into superior results.

Targeted, not brute-force

XWAI sequences AWI, RWI and FWI to the exact problem in each dataset — so the model converges on the prospect, not the noise.

Faster to a defined model

Automated QC and parameter selection cut the iterations between an early model and a drillable result from weeks to days.

Everyone can interrogate it

Sequences, jobs, parameters and cost — and rendered velocity slices — all answered in plain language, grounded in live project data.
