摘要： A well treatment system of the present invention includes a housing forming a sealed surge chamber, and a surge charge disposed within the sealed surge chamber, wherein the surge charge is adapted upon activation to penetrate the housing and to not penetrate material exterior of the housing. Fluid communication is created between the surge chamber and the wellbore when the housing is penetrated by the surge charge. The penetration permits wellbore fluid to flow quickly into the surge chamber. Fluid flow into the surge chamber may enhance a surge of flow from the formation into the wellbore.

摘要： An apparatus and method is provided to reduce interference resulting from activation of explosive devices. One type of interference is charge-to-charge interference, and another type of interference is pre-shock interference between a detonating cord and an explosive, such as a shaped charge. To reduce interference, one or more shock impeding elements are placed proximal one or more explosives to impede propagation of shock caused by detonation of the explosives. The shock impeding elements include a porous material, such as a porous liquid or solid. In another arrangement, a shock barrier may be positioned between a detonating cord and an explosive to reduce pre-shock interference. In yet another feature, an encapsulant may be provided around one or more shaped charges to enhance structural support for the shaped charges.

摘要： A transient overbalance condition is created in a wellbore interval such that a pressure of the wellbore interval is greater than a reservoir pressure in surrounding formation. Creating the transient overbalance condition causes a near-wellbore region of the formation to increase in pressure. The pressure in the wellbore interval is reduced at a rate that produces a relative underbalance condition in which the pressure in the wellbore interval is less than the pressure of the near-wellbore region of the formation, but the pressure in the wellbore interval is greater than the reservoir pressure.

摘要： An apparatus for reducing the post-detonation pressure of a perforating gun, the apparatus including a perforating gun carrying at least one explosive charge, wherein when the explosive charge is detonated the explosive charge produces a pressurized detonation gas, and a mechanism for reducing the pressure of the detonation gas proximate the perforating gun. The detonation gas pressure is desirably reduced in a time frame sufficient to create a dynamic underbalance condition to facilitate a surge flow of fluid from a reservoir into a wellbore. The pressure reduction mechanism may include singularly or in combination a heat sink to reduce the temperature of the detonation gas, a reactant to recombine with the reactant gas and reduce the molar density of the detonation gas, and a physical compression mechanism to utilize the waste energy of the detonation gas to create work, simultaneously reducing the temperature of the gas and the molar density of the detonation gas.
