Abstract: A hydrocarbon containing formation may be treated using an in situ thermal process. A mixture of hydrocarbons, H2, and/or other formation fluids may be produced from the formation. Heat may be applied to the formation to raise a temperature of a portion of the formation to a pyrolysis temperature. Heat may be supplied to the formation by reacting an oxidant with hydrocarbons adjacent to heater wellbores to generate heat. Generated heat may be transferred to the portion substantially by conduction to pyrolyze at least a portion of hydrocarbon material within the portion.

Abstract: A method and a scanning electron microscope (SEM) holder apparatus are provided for implementing examination of multiple samples. The SEM holder apparatus includes a metal plate. The metal plate includes a plurality of through holes arranged in a predefined pattern, a mounting opening, and an O-ring receiving recess extending within the metal plate to the plurality of through holes. The SEM holder apparatus includes a plurality of sample holders, each inserted within a selected one of the plurality of through holes. An O-ring is inserted within the O-ring receiving recess to provide a secure mounting of the plurality of sample holders. The O-ring protrudes partially into the through holes receiving the sample holders, providing positive holding pressure that ensures a secure mounting of the sample holders to provide electrical conductivity and vibration suppression.

Abstract: A shielded electrical connector is provided for mounting on a printed circuit board. The connector includes a dielectric housing having a plurality of terminal-receiving cavities and a plurality of board-engaging pads projecting from the bottom of the housing. A plurality of terminals are received in the cavities.
