Wet Sand Reduces Emissions
A relatively new and fast-growing innovation in regional frac sand mining is proximity mines, sometimes referred to as mobile or hyper-local mines. These mines are modular and easier to mobilize making them suitable for shorter-term sand mining projects.
Proximity mining involves excavating, washing, sizing, storing, and loading wet frac sand and is contingent on locating suitable sand deposits near the frac operations. These operations rarely, if ever, have drying facilities due to the capex needed for dryers roughly doubling the equipment costs plus longer lead times needed in obtaining air quality permits and pipeline infrastructure for natural gas and water supplies. This makes proximity mining an ideal complement to PropX’s wet sand equipment.
This powerful combination of last-mile wet sand handling equipment and proximity mining closer to the wellsite, dramatically reduces emissions and truck traffic along with providing cost savings on sand and trucking.
Liberty converted our sand and proppant transportation service into containerized moving, storage, and delivery in 2014. Our containerized system optimizes haul volumes, enhances wellsite tracking, and reduces emissions related to proppant delivery. Notably, the move has also increased our fleet uptime and efficiency because containerized sand provides an extremely fast, reliable, and predictable delivery method. The move away from pneumatic blowers has resulted in decreased truck idle time as well as a significant reduction in noise and dust generated at the wellsite.
Containerized sand has created a safer work environment for our employees and reduced truck traffic, allowing us to become better neighbors within our communities. Today, the electric belt delivery systems are integrated with Liberty’s blenders providing pinpoint measurement to match job designs.
