Our course training philosophy has been, and will continue to be, that in-person training is the best means of conveying numerous, detailed engineering concepts in a time-efficient manner. Nonetheless, in keeping with the continuing world-wide health crises, our courses have gone on-line to support participants from their home offices in 2020 and 2021. In 2022, we expect to be back to offering dominantly in-person training.

Regardless of our desires and plans, we continue to adapt to the particular needs of our clients. If an online course is desired, we are glad to provide this and have already tailored our course materials to fit an online format.

Besides offering courses directly, are courses are also currently available through RPS Nautilus, Geologica, SPE and ARMA.
