Well Construction Program in Southwest Mississippi Adapted from Information by the Southwest Mississippi Community College Know a student interested in join- ing the drilling community? The Well Construction Technology Program at Southwest Mississippi Community Col lege provides classroom and labo- ratory instruction in the use of rotary drilling and related equipment used in drilling for water, petroleum, environmen- tal, and geotechnical operations. Highly-qualified instructors will lead students through the classroom portion of the course which covers the rig, power equipment, mechanical maintenance, drilling fluids, hydraulics, and other areas associated with well drilling operations. Students are then taken to the lab- oratory portion of the course which in- cludes hands-on operation of drilling rigs, maintenance of rigs, operation of related equipment, as well as drilling and com- pletion of various types of wells. Included are basic welding, machine shop oper- ations, hydraulics, and basic industrial electricity. Graduates of the program are award- ed an Associate of Science degree once they complete the two-year program. They are also eligible to apply for examination for certification from the National Ground Water Association certification. Since 1929, the college has taken pride in serving the southwest portion of Mississippi; however, they have wel- comed students from 46 Mississippi coun- ties and 8 states. The school even offers a new smart- phone app called iSouthwest, which allows students to view course infor- mation, campus news, athletics news, directory information, images, and videos.
