CASPER, Wyo. - On Oct. 10, 2007, we had the opportunity to accompany three Unidavi University professors from Brazil. Jeancarlo Visentainer is a Language Arts Professor and was our helpful translator. Niladir Butzke is a Law Professor and Dr. Fabio Alexandrini is a Computer Science Professor. Also on the trip was Janet De Vries, Casper College Career Center Director, and Wesley Bertagnole, Casper College Career Center Specialist. Representing the Bureau of Land Management was Clinton Hernandez, Petroleum Engineer Technician, and Dawn Kulhavy, Mineral Clerk. We began the trip to the Chevron location in the Waltman field, west of Casper, by learning about their University and Brazilian culture.

When we arrived on the drill site, the three professors began to swarm us with questions. First, we discussed drill site preparation. We explained that once a site has been selected, it must be surveyed and the boundaries determined. Environmental impact studies may also be done. Lease agreements, titles, and right-of way accesses for the land must be obtained from the BLM.

The next topic we talked about was drilling the hole. We explained the steps. First the drill bit, collar and drill pipe are placed in the hole. Then the kelly and turntable are attached to begin drilling. As drilling progresses, the mud circulates through the pipe and out of the bit to float the rock cuttings out of the hole. New sections of drill pipes are added as the hole gets deeper. Once a preset depth is reached, the casing must be placed in the hole and cemented into place. This process prevents the hole from collapsing in on itself. Cement is then pumped down the casing, moving the cement to fill the space between the outside of the casing and the hole. This cement is later drilled out when the hole is further deepened to the final depth.

After leaving the location the professors inquired about oil extraction and shipment. We explained to them how the well flows under pressure and later uses pumping units. We clarified the transportation methods of pipeline and truck shipment.
