摘要： A method of pressure testing a casing string in a reverse cementing operation in a wellbore can include: introducing the casing string and a downhole tool installed within the casing string into the wellbore, wherein the downhole tool comprises a fluid flow path defined by an inner diameter of the downhole tool; introducing a cement composition into an annulus located between a wall of the wellbore and an outside of the casing string; causing the fluid flow path of the downhole tool to close against fluid flow from the annulus into at least a portion of the casing string; and increasing pressure within the portion of the casing string that is closed against fluid flow from the annulus. The fluid flow path can be closed by shifting an inner sleeve to close a flapper valve or flow ports, a bridge plug, a packer, or a ball and a ball seat.

摘要： A fracturing fluid can include: a base fluid, wherein the base fluid comprises water; proppant; a friction reducer; and a friction reducer enhancer, wherein the friction reducer enhancer is a surfactant. The friction reducer enhancer can be in a concentration greater than or equal to a critical micelle concentration. Methods of fracturing a subterranean formation can include introducing the fracturing fluid into the subterranean formation. The friction reducer enhancer can increase the hydration rate of the friction reducer, whereby friction reduction of the fracturing fluid can occur much faster than without the friction reducer enhancer.
