(7) From (8), it is evident that an error is induced at every time-step due to the truncation of the Taylor series, this is referred to as the local truncation error (LTE) of the method. For the forward Euler method, the LTE is O(h2). Hence, the method is referred to as a first order technique.
Abstract. An integrated thermal recovery process using a solvent of a pentane or hexane or both as an additive to, or sole component of, a gravity-dominated process for recovering bitumen or heavy oil from a reservoir. A pentane-hexane specific solvent fraction is extracted at surface from a diluent stream.
Definition - What does Heptane mean? Heptane is a water-insoluble hydrocarbon obtained by fractional distillation of petroleum characterized by its petrol-like odor and colorless nature. It is used in the manufacturing of paint and coating additives, adhesives, sealants, chemical intermediates and formulation solvents in industrial and consumer use.
