The Sequence That Recovers Salt From Scratch with FWI
FWI normally arrives at the end of a processing sequence. At Alaminos Canyon we run it first — AWI defines the salt from a salt-free start, RWI corrects the sub-salt trend, then the two combine. A stage-by-stage walkthrough, with AWI, RWI, and reflectivity defined along the way.

Sharpening Salt, Fixing Sub-Salt: An Update from the Alaminos Canyon Model Build
A progress update from the ALM 50 m build: interleaved TSL-AWI and RWI correct the sub-salt trend, then iterated AWI / RWI passes sharpen the salt — tracked in velocity, reflectivity, masked RWI on the key reflector, and the predicted data itself.

Breaking Through Complex Salt: Building a Gulf of Mexico Salt Model From Scratch
At Alaminos Canyon, in partnership with Shell, we built a complex Gulf of Mexico salt model from a starting point that was wrong on purpose — no salt, no picked horizons, no well data. A walkthrough of the self-correcting AWI / TSL-AWI / RWI sequence, stage by stage.
