MEDIA HIGHLIGHTS
Best Lawyers “Lawyer of the Year – Construction Litigation,” Houston, 2025
$115 Million Settlement for Enterprise Following 3-Month Bench Trial of Construction Suit
Enterprise Products Operating LLC v. Amec Foster Wheeler USA Corp.; Amec Foster Wheeler plc
Represented Enterprise in a breach of contract and fraudulent inducement lawsuit in Texas state court against Enterprise’s former general contractor, Amec Foster Wheeler USA Corp., and its British parent company, Amec Foster Wheeler plc, concerning a multi-billion dollar petrochemical refinery constructed in Mont Belvieu, Texas from 2013-2017. The project, which involved a multi-office execution approach, including high-value engineering centers overseas, hundreds of engineers, and thousands of construction personnel, experienced hundreds of millions of dollars in cost increases and exceeded planned completion targets by over a year. Over the course of six years of litigation, Enterprise overcame a special appearance by the British parent company, which was appealed to the United States Supreme Court, multiple summary judgment motions, and four motions to exclude Enterprise’s experts. Following the conclusion of a three-month bench trial that occurred from April through July 2022, the defendants paid Enterprise $115 million to settle the case before the court issued its judgment.
Significant Settlement of Plaintiff’s Breach of Contract Matter Involving Over $15 Million in Losses and an Exemplary Damages Claim
Tanos Exploration II, LLC v. PetroTech Solutions, LLC, et al.
We represented Tanos Exploration II, LLC in a suit filed in April 2020 against its chemical supplier, Petro Tech Solutions, LLC, in Harrison County, Texas for products liability, breach of contract, and breach of warranty. On December 25, 2019, one of Tanos’s wells in East Texas had a blow-out, which resulted in an out-of-control well and the evacuation of the surrounding area. Tanos got the well under control, and in investigating the cause of the blow-out, found severe corrosion in the valve at the well head. Tanos discovered that the chemicals that Petro Tech had injected into the blown-out well – and approximately 28 of their other wells – were actually highly corrosive and literally chewed away the metal to which they were exposed. Tanos spent several million dollars repairing the blown-out well, and then spent millions more in testing and working over each of its other affected wells. Tanos’s equipment losses and repair costs exceeded $12 million, and its lost reserves totaled an additional $3 million; total losses were approximately $15 million. Tanos also alleged exemplary damages against PetroTech, and months before trial, the Court found that Tanos had “demonstrated a substantial likelihood of success on the merits of a claim for exemplary damages.” After multiple continuances requested by Defendants, this matter settled very favorably for Tanos on confidential terms shortly before trial was scheduled to begin in February 2023.
Successful Resolution of Chevron’s 7-Year Dispute Against Energy Majors Regarding the Trans-Alaska Pipeline
Unocal Pipeline Company v. BP Pipelines (Alaska) Inc., et al.
Represented Chevron Corporation affiliate in seven-year litigation in Houston district court against affiliates of BP p.l.c., ConocoPhillips Company, and Exxon Mobil Corporation relating to Chevron’s withdrawal from the Trans-Alaska Pipeline System. Litigation involved a series of summary judgment motions, upon which Chevron has prevailed at each turn. After prevailing on appeal at the Houston Court of Appeals and succeeding in having the petition for review denied at the Texas Supreme Court, the case settled favorably for our client.
Major Defense Win in Multi-Billion Dollar Environmental Trial for Waste Management
Harris County, Texas, et al. v. International Paper Company, et al.
Represented Waste Management, Inc. and Waste Management of Texas, Inc. in a case brought by Harris County, Texas alleging over 40 years of discharges into the San Jacinto River from a dump site containing paper mill waste that was abandoned in the late 1960’s. Citing various sections of the Texas Water Code and Texas Administrative Code, Harris County sought daily penalties of over $3 billion from Waste Management and McGinnes Industrial Maintenance Corporation (a/k/a “MIMC”), the company that performed the disposal operations in the 1960s, and which many years later became a wholly owned subsidiary of Waste Management of Texas, Inc. Shortly before trial, the court granted a summary judgment dismissal of all claims against Waste Management, Inc. After the close of the evidence at trial, the court granted a directed verdict holding that the waste site constituted one facility for statutory purposes, meaning that Harris County could not multiply the penalties by three. On the morning closing arguments were scheduled, Harris County agreed to settle with Waste Management of Texas and MIMC for $29.2 million.
Summary Judgment and Dismissal Wins for FTE in Putative Nationwide Class Actions
Verde v. FTE Automotive USA, Inc., et al.

Substantial Plaintiff’s Settlement in Shareholder Oppression Suit With $100 Million+ in Damages
Scott Martin, et al v. Martin Resource Management Corp., et al.
Represented Keeneland Capital Management, LLC (“KCM”) in a shareholder derivative and individual suit involving its investment in Martin Resources Management Corporation (“MRMC”), a closely-held energy corporation. KCM purchased a significant number of shares in MRMC from a key stakeholder, and was assigned that seller’s causes of action against members of management and the Board of Directors for, among other claims, shareholder oppression, breach of fiduciary duty, wrongful entrenchment and dilution, abuse of control, gross mismanagement and fraud stemming from the Directors’ alleged improper issuance of over $50 million of MRMC stock. MRMC and the MRMC Employee Stock Ownership Trust also opposed KCM in this action, and, along with the other defendants, asserted counterclaims for over $20 million in alleged damages against all plaintiffs and other third parties. After two years of intense litigation involving several other related lawsuits, the case settled favorably for KCM for a confidential amount.
Secured Favorable Defense Settlement in $42 Million Construction Matter
