Advanced drilling systems and methods

New systems and methods capable system for drilling are disclosed. An example system can include a vertically-moving platform supporting a gyrotron capable of transmitted electromagnetic energy down a waveguide such that, as the vertically-moving platform moves downward, energy transmitted by the gyrotron through the waveguide will progressively drill a borehole in the earth..


System and detecting hydrogen sulfide in a formation sampling tool

A drilling system includes a downhole sampling tool configured to be placed in a wellbore of a subterranean formation and configured to pump formation fluid from the subterranean formation into the downhole sampling tool. The downhole sampling tool includes internal components configured to route the formation fluid through the downhole sampling tool and drill collars configured to hold the internal components of the downhole sampling tool.

Dissipative surfactant aqueous-based drilling system for use in hydrocarbon recovery operations from heavy oil and tar sands

A water-based drilling fluid which includes an aqueous fluid and a water-soluble dissipative surfactant composition is described, wherein the dissipative surfactant composition includes at least one fatty acid or ester derivative of a plant or vegetable oil. Also described are methods of using such aqueous-based drilling fluids including the dissipative surfactant composition as described in hydrocarbon recovery operations associated with oil/tar sand, where such fluids act to increase the dispersant qualities of hydrocarbons within the oil/tar sand, and where such fluid exhibit a reduced coefficient of friction..
