Profile: Stavens Bros., Inc. specializes in offering well drilling & pumping and hydrofracturing services. We also provide well surging services. Hydrofracturing operation consists of introducing large volumes of water to the well and pressurizing it to produce up to 3,000 PSI. This extreme pressure lifts the foundation of the well system and causes small cracks to form in the walls, allowing additional water to trickle into the well.
