Reverse Circulation Drilling
In sand and gravel formations, the reverse circulation method of drilling is often chosen for high capacity wells. Reverse circulation drilling has the advantage of a large diameter bore hole, which can be up to 54” and high capacity well yield. Reverse circulation drilling uses no artificial drilling muds during drilling, only clean, clear water, thus avoiding formation plugging or extensive screen development.
Cable Tool Drilling
Bastin Logan Water Services, Inc. (BLWSI) is a leader in the industry of cable tool drilling. While cable tool drilling is the oldest and most time consuming method of drilling, it has huge benefits in well production. Cable tool drilling is excellent for pin point accuracy in formation sampling and precise screen selection. Whether it be a 6-inch test well or a 30-inch production well, BLWSI sampling is second to none. Cable tool drilling is also very effective in formations where large boulders are encountered.
