Abstract: A fracturing operation is done in open hole without annular space isolation. The annular space is spanned by telescoping members that are located behind isolation valves. A given bank of telescoping members can be uncovered and the telescoping members extended to span the annular space and engage the formation in a sealing manner. Pressurized fracturing fluid can be pumped through the telescoped passages and the portion of the desired formation fractured. In a proper formation, cementing is not needed to maintain wellbore integrity. The telescoping members can optionally have screens. Normally, the nature of the formation is such that gravel packing is also not required. A production string can be inserted into the string with the telescoping devices and the formation portions of interest can be produced through the selectively exposed telescoping members.

Abstract: A screen section is made with variable resistance to flow in the screen material to balance the flow along the screen length. In one variation different discrete zones have screens configured for different percentages of open area while all have the same particle filtration capability. In another variation discrete portions have differing amounts of overlapping screen portions so as to balance flow without affecting the particle size screened. The cross-sectional shape of a wire wrap underlayment for the screen is made closer to trapezoidal to decrease the angle of opening for the incoming flow paths toward the base pipe. In this manner flow resistance is reduced and flow is increased due to reduced turbulence.

Abstract: Una operación de fracturación se realiza en pozo abierto sin aislamiento de espacio anular. El espacio anular se expande por miembros extensibles que se colocan detrás de las válvulas de aislamiento. Los miembros extensibles pueden comprender un tapón biodegradable que permite la extensión de los miembros extensibles por la aplicación de presión. Con el tapón colocado en su lugar, la presión adicional puede suministrarse hasta que al menos una porción del material degradable se impulsa en la superficie del yacimiento. Al menos una porción del material degradable impulsado proporciona un sello entre el extremo de los miembros extensibles y la superficie del yacimiento para permitir a la presión desarrollarse hasta que se excede el gradiente de fracturación del yacimiento y el yacimiento se fractura.

Abstract: An apparatus for screening earth formation components includes: a base pipe configured to allow the passage of formation fluid therethrough; and a foam layer disposed radially outwardly of the base pipe and configured to allow the passage of formation fluid therethrough and minimize the passage of formation solids therethrough, the foam layer including a plurality of hollow structures forming windows therebetween. A method of manufacturing an apparatus for screening earth formation components is also disclosed.

Abstract: A fracturing operation is done in open hole. The annular space is spanned by telescoping members that are located behind isolation valves. A given bank of telescoping members can be uncovered and the telescoping members extended to span the annular space and engage the formation in a sealing manner. Pressurized fracturing fluid can be pumped through the telescoped passages and the portion of the desired formation fractured. In a proper formation, cementing is not needed to maintain wellbore integrity. In formations that need annular space isolation, the string in a preferred embodiment can have an external material that grows to seal the annular space in lieu of a traditional cementing operation.

Abstract: Composite tubulars that have not been polymerized and are thus flexible enough to be coiled are delivered into a wellbore and expanded. The expansion occurs from an external catalist such as heat or releases the internal catalyst and allows the expanded tubular to become rigid. Optionally, healing agents can be imbedded in the tubular wall to be released to seal subsequently forming cracks.
