    摘要: A cement composition is provided including a cement and a low reactivity particle coated with a swellable polymeric material. The low reactivity particle is coated with a swellable polymeric material at a concentration of about 10 weight percent to about 50 weight percent, based on the weight of the cement. The swellable polymeric material swells to a larger volume when exposed to one or more hydrocarbons, depending on the selected polymeric material. The cement composition is used in a method as a self-sealing cement for cementing an oil and gas well, thereby minimizing or mitigating the unwanted migration of water or hydrocarbons.

    摘要: The A pile-driving apparatus includes a pile, a shoe tip coupled to a toe of the pile, and a drill string disposed within the pile. The drill string includes a gripping device coupling the drill string to the pile and a hammer deployed into the pile such that the hammer is capable of transmitting a force to the shoe tip. A method, includes positioning a hammer in a pile such that the hammer is capable of transmitting a force to a shoe tip; positioning, in the pile, a portion of drill pipe having a gripping device to engage the pile; and deploying the pile beneath the surface of a body of water.
