CoCounsel Legal for oil and gas
Defensible judgment, from wellhead to market
CoCounsel Legal grounds first-pass review of leases, joint operating agreements, and gathering and transportation agreements in Westlaw and Practical Law, so your attorneys can defend every position they sign

Built for the documents that run upstream, midstream, and downstream
Every output traces to a source
CoCounsel Legal, our Fiduciary-Grade AI™ solution, checks every output against Westlaw and Practical Law content — rather than a general web search — with links back to verified sources. Title attorneys and business-unit counsel can validate the authority behind every answer — cited, not just confident.
Contract chains, compared side by side
CoCounsel Legal answers questions about cross-state royalties, indemnity, or notice periods with results grounded in Westlaw and Practical Law. Every citation is linked, so your legal team can defend every position without slowing the business down.


Oil and gas coverage, upstream to downstream
Practical Law content spans upstream, midstream, and downstream operations, with multi-jurisdictional regulatory requirements. From research to drafting and translation — including Spanish, Portuguese, Arabic, and Chinese — support counsel working across international operations and multiple regulatory regimes.
Multijurisdiction research and translation
Research and translation support covers Spanish, Portuguese, Arabic, and Chinese, plus Practical Law multinational research spans more than 45 jurisdictions.
Enterprise-grade security and data handling
We never use customer data for model training. Encryption protects data at rest and in transit, and requests stay inside the Thomson Reuters cloud boundary, with data residency options.
In-app redlining in Microsoft Word
Redline rendering and AI-assisted transactional drafting support are now available in beta within Microsoft Word.
Westlaw Brief Builder in CoCounsel
Agentic drafting handles motions and briefs from intake through citation verification, grounded in Westlaw Deep Research, KeyCite, and Practical Law, with local court rules applied to formatting. This feature has been generally available in the U.S. since August 20, 2026.
Legal Tracker integration
Outside counsel spend is benchmarked against comparable matters, closing the loop between work moved in-house and its measurable cost.
Thomson, a purpose-built model
Thomson, a first-of-its-kind AI model, powers Tabular Analysis. Trained on decades of our proprietary legal, tax, and regulatory content, it has native access to that authority rather than general web content.
