Land FWI, end-to-end — powered by TSL-FWI

An integrated workflow — from data preparation to angle-dependent reflectivity — running on cloud-native infrastructure. TSL-FWI objective functions handle near-surface heterogeneity and unmodelled amplitudes, exploiting low-frequency content from the first iteration.

Standard covers most regions. Pick Complex for severe near-surface effects (frost / permafrost layers, karst, evaporitic deposits, large topography) or strong structural complexity (thrust belts, dense faulting, strong anisotropy) — these need more iterations and QC.
Approximate depth to the primary target. Examples: near-surface plays (shallow); typical reservoirs such as Eagle Ford or Wolfcamp (intermediate); sub-salt or deep gas like Tuscaloosa or Haynesville (deep).
Salt environments add structural complexity (steep dips, illumination shadows, large velocity contrasts) and need more iterations and QC.
Targeted updates split each survey into sub-areas, each updated with its own FWI settings — higher engineering effort (more parameterisations, more QC, integration between zones), so more expensive and slower than a single entire-survey update.

How is the price built?

A fixed engagement fee plus a variable component that scales with maximum FWI frequency and survey area, and is then adjusted by target complexity, target depth and update style — these capture both compute and human time (parameterisation, QC, integration), with the human side usually dominating. Skipping pipeline stages reduces the variable part. Multi-survey merging and new-acquisition coordination add small fixed amounts. Interpretation bundles a Thinkonward deliverable on top of the FWI outputs.
