After an oilfield accident, it is normal to feel pressure to settle quickly. You may be dealing with severe burns, crush injuries, or worse, along with mounting medical bills and missed work, while the well operator's insurance adjusters push for a quick settlement before you know the full impact of your injuries. Oil and gas companies often act quickly to evaluate claims and may offer settlements that do not fully reflect your losses.

At Thiessen Law Firm, our oilfield accident practice operates under the principle that's powered us to 220+ jury trials: we fight like hell for the people. We understand how oil and gas companies and their insurers investigate rig and well-site accidents, evaluate injuries, and look for ways to reduce or deny claims. We investigate what happened, gather & preserve evidence, document your injuries & losses, and handle the insurance company on your behalf.

At Thiessen Law Firm, we've built our reputation on fearless advocacy, strategic expertise, and unwavering commitment to our clients' futures. Don't let an oil company or its insurer decide what your claim is worth. You don't pay unless we win. Don't wait, schedule your free consultation with Thiessen Law Firm today.

“We Fight Giants” — and they meant it!"

Thiessen Law Firm was incredibly helpful after my car wreck. Neila and Joel were professional and supportive. Syrina was quick to help me get my check, and I truly appreciate how responsive and helpful everyone was. I’m grateful for the way they fought for me. I would recommend Thiessen Law Firm to anyone needing assistance after an accident.

“Made Dealing with Insurance Companies Stress Free”

Got rear-ended by a careless driver and Thiessen Law Firm made dealing with Insurance companies stress-free. Jesenia handled my case from cradle to grave where I underwent medical care and car repairs as she dealt with the insurance making a bad experience as stress-free as possible. The silver lining was the insurance settlement, my full recovery, and my truck restored to better condition than before.

Houston Oilfield Accident Lawyers You Can Trust

Oil and gas companies want you to believe they're too big to fight. They want you to feel overwhelmed, intimidated, and desperate enough to accept whatever lowball offer they throw your way. They're counting on you not knowing your rights, not understanding your claim's true value, and definitely not hiring attorneys who know how to beat them.

At Thiessen Law Firm, we fight giants. Taking on corporate America isn't just what we do — it's who we are. We built our reputation fighting for the people against powerful institutions that thought they were untouchable. Whether it's criminal prosecutors with the full weight of the state behind them or multinational energy and insurance corporations with unlimited legal budgets, we've made a career out of proving that normal people can beat the giants.
