摘要: A method of treating a subterranean formation with a retarded self-diverting fluid system. The method includes contacting the formation with a mixture of acid, chelating agent, and betaine surfactant in which the betaine surfactant is mixed with an aqueous solution of the chelating agent in which the pH has been adjusted to a pH of below about 3.0, but above the pH at which the free acid of the chelating agent precipitates, and the resulting fluid system is utilized for both acid fracturing and matrix stimulation, as well as workover procedures such as scale and filter cake removal, especially in high temperature formations.

摘要: A semiconductor crystal and associated growth method are disclosed. The crystal includes a seed portion and a growth portion on the seed portion. The seed portion and the growth portion form a substantially right cylindrical single crystal of silicon carbide. A seed face defines an interface between the growth portion and the seed portion, with the seed face being substantially parallel to the bases of the right cylindrical crystal and being off-axis with respect to a basal plane of the single crystal. The growth portion replicates the polytype of the seed portion and the growth portion has a diameter of at least about 100 mm.

摘要: A method is disclosed for producing a high quality bulk single crystal of silicon carbide in a seeded growth system and in the absence of a solid silicon carbide source, by reducing the separation between a silicon carbide seed crystal and a seed holder until the conductive heat transfer between the seed crystal and the seed holder dominates the radiative heat transfer between the seed crystal and the seed holder over substantially the entire seed crystal surface that is adjacent the seed holder.
