01 — The ranking
The Houston Oil & Gas board
Sartori's view of the best Oil & Gas law firms in Houston groups 6 firms by relative Oil & Gas market position in Houston. Tiers are plain-language labels only — never scores — and within-tier sequence rotates without implying rank.
This band holds the firms whose Oil & Gas presence defines the Houston standard. Labels are editorial words, not scores; monthly order inside the tier carries no meaning.
Highly active firms show sustained Oil & Gas mandate flow and visible energy-side bench strength in Houston, just below the market-leader band. Order inside the tier is non-hierarchical.
Firms in this tier are part of the core Houston Oil & Gas map — known, staffed and active on energy mandates — with relative standing expressed only in plain language.
All counts are shown as bands, never precise headcounts. Notable firms sit outside the tiers by design: verified minimal presence, not assessed at full tier depth.

No third-party legal-directory bands are used as an input.
