Abstract: A system and method for fracturing a well can comprise a base pipe comprising an insert port capable of housing a stop ball partially within the chamber of it, and a sliding sleeve. The sliding sleeve can comprise a first sleeve with an in inner surface. That inner surface can comprise a void. The first sleeve can be maneuverable into two positions. In the first position, the void can rest on a surface of the base pipe not comprising an insert port. Such positioning can prevent a stop ball from exiting the chamber of the base pipe. In the second position, the void can rest over an insert port. Such positioning can allow the stop ball to the chamber of the base pipe and to enter the void.

Abstract: According to a preferred aspect of the instant invention, there is provided a boat hull that is an improvement over the state-of-the-art stepped hull. More particularly, in contrast to prior art designs, the instant steps are specifically constructed to have an opening/air passage situated on the side of each step. The air passage will be preferably placed on the side of the step closest to the surface of the water or farthest away from the keel of the boar. This feature tends to introduce more air under the boat, thereby reducing water drag on the hull and improving its overall performance.

Abstract: An integrated apparatus for use in hydrocarbon-producing wells is provided. A device for controlling inflow from a subterranean formation (ICD), a filtration medium for fine particle exclusion and a sealing element (packer) are disposed along a single cylindrical mandrel, preferably an oilfield tubular. The apparatus may be used in a completion method to enhance production rates and increase the total recovery from a subterranean hydrocarbon-producing formation.

Abstract: According to a first preferred aspect of the invention, there is provided a downhole sand screen device for use in well completions that comprises a plurality of isolated individual sand screens. Further, in the preferred arrangement the instant invention consists of two screens, one concentrically nested inside of the other, and further wherein the screen sections are not continuous but rather are periodically interrupted by sections of blank pipe. Further, the screen sections are arranged so that a screen section on the outer pipe will be matched by a corresponding, but staggered, blank pipe section on the inner pipe. As a consequence, if a hole develops in one of the outer screen sections the movement of sand will be blocked from entering the wellbore by a second/inner screen.
