Abstract: A method includes receiving, by a first computer from a second computer, a stateless API request message comprising update value data, a consensus token, and a user identifier. The first computer determines whether or not the consensus token matches a previously stored consensus token. If the consensus token matches the previously stored consensus token, the first computer retrieves stored value data from a value data database based on the user identifier. The first computer then updates the stored value data with the update value data. The first computer generates an API response message comprising an indication of the update. The first computer transmits, to the second computer, the API response message.

Abstract: A process may include providing heat from one or more heaters to at least a portion of a subsurface formation. Heat may transfer from one or more heaters to a part of a formation. In some embodiments, heat from the one or more heat sources may pyrolyze at least some hydrocarbons in a part of a subsurface formation. Hydrocarbons and/or other products may be produced from a subsurface formation. Certain embodiments describe apparatus, methods, and/or processes used in treating a subsurface or hydrocarbon containing formation.
