Chevron Wells Drilled Since 2023
Chevron’s factory model approach, involving drilling multiple wells from a single pad, has significantly increased efficiency and reduced costs. Looking ahead, Chevron aims to enhance secondary recovery techniques to further boost production, continuing the trend of innovation in shale development.
The evolution of the Permian Basin from a challenging oil reserve to one of the world’s leading oil production sites showcases the transformative power of technological innovation in the oil and gas industry. Nicole Champenoy, the shale and tight asset class director at Chevron, reminisces about the early days when vast amounts of oil were trapped in dense rock formations, and the industry struggled to extract it economically.
Technological Breakthroughs
Hydraulic Fracturing and Horizontal Drilling
Champenoy highlights two pivotal techniques that revolutionized production in the Permian Basin:
- Horizontal Drilling: This method involves drilling vertically down thousands of feet before changing direction to drill horizontally. This approach allows access to larger areas of the oil-rich rock formations.
- Hydraulic Fracturing: Known as fracking, this technique involves injecting fluids at high pressure into the rock, creating fractures that allow oil and gas to flow more freely.
These advancements overcame the limitations of earlier technologies, making it possible to economically extract oil from dense rock formations and transforming the Permian Basin into a prolific oil production site.
The Factory Model
Chevron’s modern approach to drilling in the Permian Basin employs a factory model, which involves drilling multiple horizontal wells from a single well pad and completing them with hydraulic fracturing. This model has several advantages:
- Prioritization: Focuses on the most promising opportunities.
- Cost Reduction: Lowers drilling costs and shortens the time from drilling to production.
- Increased Efficiency: Triples the pace of Chevron’s drilling program.
Safety and Production Records
Safety remains a priority, with Chevron aiming to prevent fatalities, serious injuries, and illnesses. The success of these efforts is reflected in the company’s performance. In the fourth quarter of last year, Chevron set a quarterly record with the Permian Basin reaching 867,000 barrels of oil-equivalent per day.
Future Innovations
Chevron is now focusing on improving secondary recovery techniques, such as gas and chemical injection, to extract even more oil and gas after the initial recovery. Champenoy is excited about the ongoing innovations and the potential for future growth in production.
“We’ve come so far in the past decade, but we have so much ahead of us. It’s an awesome time to be working in shale,” she said.
The transformation of the Permian Basin exemplifies the impact of innovation in the oil and gas industry, demonstrating how technological advancements can unlock vast resources and drive efficiency. Chevron’s successful implementation of horizontal drilling, hydraulic fracturing, and a factory model approach has revitalized production and set new benchmarks for the industry. As Chevron continues to explore secondary recovery techniques, the future holds promising potential for even greater advancements in shale development, ensuring sustained growth and production efficiency.
