Deadline for entries was June 30th.

Why I belong to the National Drilling Association:

"Ambient Technologies, Inc. membership and participation of conferences has allowed us to meet some of our vendors in person and share discussions about future business. We established relationships that help our operations locally and internationally. Several of the lectures provided ideas for better servicing our clients and resolving drilling related problems. For example, the reaction of drilling mud with the existing soils can cause problems, and, the option of installing electronic peizometer imbedded in grout mixtures. I will continue to be involved in the organization and expose my staff to the training as it becomes available."
