PRESSURE ACTUATED DISINTEGRATION OF BULK MATERIALS AND OILFIELD RELATED COMPONENTS

Abstract

A pressure disintegrable device includes a first volume that further includes a first portion and a second portion. The first portion transmits, to the second portion, pressure applied to the first volume. The melting temperature of the second portion, in response to the transmitted pressure, decreases as the transmitted pressure increases beyond a predetermined pressure. The pressure disintegrable device may also include a layer on the first volume that creates a seal between the first volume and an external structure

Description

BACKGROUND

Hydrocarbon fluids such as oil and natural gas are obtained from a subterranean geologic formation, referred to as a reservoir, by drilling a well that penetrates the hydrocarbon-bearing formation. Once a wellbore is drilled, various forms of well completion components may be installed in order to control and enhance the efficiency of producing the various fluids from the reservoir.

During production of hydrocarbon fluids from a well, it is sometimes helpful to temporarily isolate different zones of a well using an isolation component. Zones are linear sections of a well that may be at different depths. One commonly used isolation component is a slurry including a cement binder, filler materials such as sand and an aggregate such as pea gravel, and one or more fluids. The slurry is pumped down into a predetermined location within a well and the slurry is hardened to form concrete which creates an isolation component within the well. A tool such as a bridgeplug is also used as an isolation component. The bridge plug is lowered into the well to a predetermined location and the bridgeplug is actuated to create a seal that prevents fluids and gases from traversing along the length of the well.

Once the isolation component is in place, operations are performed on the isolated section of the well. For example, hydraulic fracturing may be employed to modify the production of the well in the isolated zone. Once the operations are complete, the isolation component is removed. Zone isolation may be used repeatedly to modify the production of the well.

SUMMARY

In general, in one aspect, a pressure disintegrable device includes a first volume that further includes a first portion and a second portion. The first portion transmits, to the second portion, pressure applied to the first volume. The melting temperature of the second portion, in response to the transmitted pressure, decreases as the transmitted pressure increases beyond a predetermined pressure.

In general, in one aspect, a method of operating a pressure disintegrable device includes applying a pressure to a first volume including a first portion and a second portion disposed on the first portion; transmitting, by the first portion, the pressure to the second portion in response to the pressure applied to the first volume; decreasing, by the second portion, a melting point of the second portion in response to the transmitted pressure; and changing, by the second portion, a state of the second portion from solid to liquid in response to the decrease in the melting point of the second portion.

In general, in one aspect, a method of producing a pressure disintegrable device includes obtaining a first plurality of grains of a first material and obtaining a second plurality of grains of a second material that decreases a melting point of the second material as an applied pressure increases beyond a predetermined pressure. The method further includes forming a first volume by consolidating the first plurality of grains to form a first portion and consolidating the second plurality of grains to form a second portion disposed on the first portion

Embodiments may take the form of heterogeneous materials, devices, and methods of operating devices that structurally fail when exposed to a pressure greater than or equal to a predetermined pressure. In one or more embodiments, a heterogeneous material includes a first portion that does not decrease its melting point as pressure increases. In one or more embodiments, the heterogeneous material also includes a second portion that decreases its melting point as an externally applied pressure is increased beyond a predetermined pressure. In one or more embodiments, the first portion and second portion are arranged to form a heterogeneous material that disintegrates when an externally applied pressure is equal to or greater than a predetermined pressure and predetermined temperature. In one or more embodiments, the disintegration is caused by the second portion changing from a solid to a liquid in response to an applied pressure and applied temperature. In one or more embodiments, the applied temperature may simply be the ambient temperature while in other embodiments a heating source may raise the temperature of the second material to facilitate changing the phase of the second material from solid to liquid.

In accordance with one or more embodiments, devices and materials may take the form of oilfield-related components or materials such as balls, plugs, darts, receptacles or seats, anchors, collets, pressure housings, flow-thru housings, mandrels, or any other isolation component. Devices and materials may also take the form of components that are formed in situ using cements. In one or more embodiments, cement is a binding material that is mixed with other materials such as gravel, sand, and one or more liquids to form a workable material or a slurry that hardens into a solid over a period of time. The components or materials are used to isolate sections of a well. For example, a ball may be used in conjunction with a pre-existing seat located in a well to block the flow of fluids and gases by forming a seal when the ball is pressed against the seat. A plug or a cement may also be used to block the flow of fluids and gases by sealing the entire cross section of the well.

The isolation of fluids and gases is indicated by the arrows with dashed tails as shown in FIG. 5. In one or more embodiments, the pressure disintegrable device (501) is a single unit at the surface and is lowered into the well before isolating the first zone (502) from the second zone (503). In one or more embodiments, the pressure disintegrable device (501) is a slurry that includes cement binder at the surface and is pumped into the well at a desired location to form the pressure disintegrable device (501) before isolating the first zone (502) from the second zone (503).

When the second portion (202) changes state, the structural integrity of the pressure disintegrable device (701) fails nearly instantly. In FIG. 7, the pressure disintegrable device (701) breaks down into six large chunks but in practice the pressure disintegrable device (701) may disintegrate into any number of pieces of any size. Once the pressure disintegrable device (701) disintegrates, the pressure disintegrable device (701) no longer isolates the first zone (702) from the second zone (703) and fluids and gases are no longer restricted from traversing between the first zone (702) and second zone (703).

A person of ordinary skill in the art will recognize that the operation of the pressure disintegrable device (101) shown in FIGS. 5-7 is an example and should not be construed to limit the operation of the pressure disintegrable device (101) to well or oil field operations.
