The OilWell Difference: From Houston to Harrison County
What sets OilWell Cannabis apart isn’t just our products—it’s our story, our science, and our commitment to Harrison County. Founded in Houston by Colin Valencia, our company was born from a personal mission that began with a paralyzed pitbull named Bentley and grew into a movement that’s changing lives across Texas and beyond.
The Bentley Miracle: Our Foundation
In 2008, our founder’s beloved pitbull Bentley was diagnosed with severe health issues that left him paralyzed in his back legs. Veterinarians recommended euthanasia, as traditional pain medications would destroy his internal organs. Facing the loss of his closest companion, Colin refused to accept defeat.
A chance conversation about CBD led to an extraordinary discovery. Using a homemade golden paste formula containing CBD oil, Colin began treating Bentley’s condition. Within weeks, Bentley showed signs of improvement. Months later, he was walking again. Against all medical odds, Bentley lived for ten more years—a decade of quality life that veterinary medicine said was impossible.
This miracle didn’t just save a dog; it created a legacy. During those ten years, Colin developed specialized cannabis formulations to address Bentley’s evolving needs:
- Neurodegeneration formulas to maintain cognitive function
- Dementia formulas to preserve memory and awareness
- Glaucoma formulas to manage eye pressure
- Arthritis formulas to maintain mobility
Every OilWell product carries Bentley’s legacy forward, offering Harrison County residents the same level of care, precision, and hope that gave a paralyzed dog ten more years of life.
From McAllen to Marshall: A Journey of Transformation
Colin’s path to becoming Harrison County’s trusted cannabis authority began in the border town of McAllen, Texas, directly across from Reynosa, Mexico. Growing up in this complex environment taught him invaluable lessons about resilience, innovation, and the importance of creating safe, legal alternatives to dangerous substances.
The McAllen-Reynosa borderplex is a study in contrasts—vibrant culture alongside economic challenges, thriving retail sectors adjacent to limited opportunities, and the constant presence of both danger and hope. These early experiences shaped Colin’s approach to cannabis:
- Risk Assessment: Learning to evaluate opportunities under impossible circumstances
- Trust Building: Understanding that business success depends on keeping your word
- Supply Chain Mastery: Creating reliable systems when conventional options fail
- Quality Focus: Recognizing that cutting corners costs lives, not just profits
When Colin moved to Houston and founded OilWell Cannabis, he brought this borderland wisdom with him. The result? A company that combines scientific precision with genuine compassion, offering Harrison County residents products that work as hard as they do.

THCa: The Game-Changer for Harrison County
THCa (tetrahydrocannabinolic acid) is the non-psychoactive precursor to THC that’s revolutionizing legal cannabis. Here’s why Harrison County residents are choosing THCa:
The Science Behind THCa
THCa exists naturally in raw cannabis plants. With its carboxylic acid group intact (C₂₂H₃₀O₄), it offers therapeutic benefits without the psychoactive effects associated with traditional THC. When heated (above 220°F), THCa decarboxylates—losing its COOH group as CO₂—to become Delta-9 THC (C₂₁H₃₀O₂).
This dual-pathway capability gives Harrison County residents unprecedented control over their cannabis experience:
Pathway 1: Raw THCa (Non-Psychoactive)
- Consume sublingually or in edibles without heating
- Benefits: Anti-inflammatory, neuroprotective, anti-nausea, appetite stimulation
- Perfect for daytime use, medical applications, and those sensitive to THC
Pathway 2: Decarboxylated THCa (Full Psychoactive Effects)
- Heat through smoking, vaping, or cooking
- Benefits: Pain relief, euphoria, appetite stimulation, sleep aid
- Provides the traditional cannabis experience when desired
Why Harrison County is Choosing THCa
- Legal Compliance: THCa flower contains less than 0.3% Delta-9 THC, making it fully compliant with Texas and federal law
- Patient Control: You decide your experience level—therapeutic or psychoactive
- Pharmaceutical-Grade Quality: Our THCa products undergo rigorous testing for potency and purity
- Full-Spectrum Benefits: Our formulations preserve the entourage effect with multiple cannabinoids and terpenes
- Versatile Applications: From smoking to edibles to sublingual oils, THCa adapts to your lifestyle
THCa Research: What Science Says
Recent studies confirm what Harrison County residents are experiencing firsthand:
- NIH 2024: THCa is a potent PPARγ receptor agonist, protecting brain cells from oxidative stress and responsible for the majority of anti-inflammatory activity in colon inflammation models
- NIH 2023: THCa ameliorated Alzheimer’s-like features in mouse models through COX-2 inhibition
- Washington State University 2024: THCa shows promise for neuroprotection and anti-inflammatory applications
- University of Sydney 2024: THCa demonstrates potential for pain management and neurological support
