34 <br /> Slide #26 <br /> Commissioner Questions cont. <br /> • Impacting other wells? <br /> • All wells run the risk of impacting other wells, community or private. <br /> Community wells are typically focused on due to the higher demand they <br /> require with more residences connected. However, the increased <br /> efficiency of operators and distribution systems with the higher scruple of <br /> regulatory agencies means they are also generally maintained and <br /> monitored to a higher degree than private wells. <br /> • 24-hour drawdown tests performed on community wells are a great <br /> opportunity to monitor nearby wells for fracture interconnectivity. <br /> Slide #27 <br /> Commissioner Questions cont. <br /> • Costs to drill? <br /> • This can varywidely, but the major expenses in drilling are the surface casing,well <br /> diameter,and depth requirements. <br /> • Wells with 100'or more surface casing become very expensive due to specialty <br /> equipment holding the borehole stable during casing installation and the expense of <br /> larger piping materials for the casing. <br /> • Deeper wells are more expensive as greater depths frequently correlate with Longer drill <br /> times. Footage prices increase with depth which coincides with those longer drill times. <br /> • Access to sites across difficult terrain and strict regulations on sedimentation during <br /> drilling can also increase prices. <br /> • Costs to maintain? <br /> • General maintenance is outside the scope of our work, but most operators will replace <br /> some of the mechanical equipment like Rumps and motors in time.Should not have to <br /> replace very frequently if properly maintained. <br /> • Mineral build-up may also require well maintenance, but this can be reduced if the well <br /> is monitored and regulated appropriately. <br />
