Abstract

A swelling element rate regulation technique and product features an outer coating on a core of an element. The core is reactive to hydrocarbons or water depending on how it is configured. The surrounding coating is preferably formed of fine ground particles of a non-swelling polymer mixed in a solvent such as methyl-ethyl-ketone that is applied in a thin layer to the core exterior. This uncured outer layer is then contacted by a patterned surface. The patterned surface is pressed firmly against the uncured polymer/solvent mixture and transfers an inverse of the pattern to the surface of the coating. As pressure is applied, heat may also be applied to cure the coating. The resulting pattern is designed such that openings in the coating are created that regulate infiltration of water or other fluids through it and, as a result, the rate of swelling in the wellbore. Swell rate in governed in part by the ratio of the exposed area of the swelling compound to the total volume of the swelling compound. The smaller this ratio, the slower the rate of swell. The pattern created in the non-swelling layer may also provide limited mechanical restraint of the swelling element, further slowing the process.

Description

APPLICATION FOR PATENT
Title: Delaying Swelling in a Downhole Packer Element
Inventor: Edward T. Wood and Edward O'Malley FIELD OF THE INVENTION
[0001] The field of this invention relates to downhole packers and plugs that use a swelling element and more particularly to design that delay the onset of swelling once the element is run downhole.
BACKGROUND OF THE INVENTION
[0002] Packers are used downhole to isolate portions of a wellbore from each other. There are many styles of packers. Some set by longitudinal compression of the sealing element by fluid pressure applied to a setting tool or by mechanical force such as from setting down weight. Other designs involve elements that are inflated. More recently, elements that swell to a sealing position on exposure to well fluids have been used. There have been many variations as outlined below.
[0003] Packers have been used that employ elements that respond to the surrounding well fluids and swell to form a seal. Many different materials have been disclosed as capable of having this feature and some designs have gone further to prevent swelling until the packer is close to the position where it will be set. These designs were still limited to the amount of swelling from the sealing element as far as the developed contact pressure against the surrounding tubular or wellbore. The amount of contact pressure is a factor in the ability to control the level of differential pressure. In some designs there were also issues of extrusion of the sealing element in a longitudinal direction as it swelled radially but no solutions were offered. A fairly comprehensive summation of the swelling packer art appears below:
I. References Showing a Removable Cover Over a Swelling Sleeve 1) Application US 2004/0055760 Al
Figure 2a shows a wrapping 110 over a swelling material 102. Paragraph 20 reveals the material 110 can be removed mechanically by cutting or chemically by dissolving or by using heat, time or stress or other ways known in the art. Barrier 110 is described in paragraph 21 as an isolation material until activation of the underlying material is desired. Mechanical expansion of the underlying pipe is also contemplated in a variety of techniques described in paragraph 24.
2) Application US 2004/0194971 Al
This reference discusses in paragraph 49 the use of water or alkali soluble polymeric covering so that the actuating agent can contact the elastomeric material lying below for the purpose of delaying swelling. One way to accomplish the delay is to require injection into the well of the material that will remove the covering. The delay in swelling gives time to position the tubular where needed before it is expanded. Multiple bands of swelling material are illustrated with the uppermost and lowermost acting as extrusion barriers.
3) Application US 2004/0118572 Al
In paragraph 37 of this reference it states that the protective layer 145 avoids premature swelling before the downhole destination is reached. The cover does not swell substantially when contacted by the activating agent but it is strong enough to resist tears or damage on delivery to the downhole location. When the downhole location is reached, pipe expansion breaks the covering 145 to expose swelling elastomers 140 to the activating agent. The protective layer can be Mylar or plastic.

[0004] While trying to delay the progress of swelling has been tried before the problems have been in execution of a workable design. Chief among the issues affecting prior designs has been the problem of getting whatever covering was used to adhere to the underlying swelling element once introduced into the well. For example published US Application 2004/0020662 describes an embodiment having an outer nitrile layer over a nitrile element where the outer coating leaves portions of the core exposed for contact with well fluids so as to regulate the rate of swelling. What this reference does not discuss is the difficulty in getting two layers of nitrile to adhere to each other in a downhole environment. Tests with the concept disclosed in this reference have revealed that there is an adhesion problem in the interface between the layers in the downhole environment and that undermines the desired effect of regulating the rate of swelling of the underlying core of the packer element. [0005] The present invention, applicable to element assemblies that swell in hydrocarbons or water addresses the problems of past designs by formulating a coating that will adhere and while doing so allow the migration of the fluid that triggers the swelling at the desired rate. These and other aspects of he present invention will become more apparent to those skilled in the art from a review of the description of the preferred embodiment and the associated drawing while the claims that are appended below indicate the full scope of the invention.
SUMMARY OF THE INVENTION
[0006] A swelling element rate regulation technique and product features an outer coating on a core of an element. The core is reactive to hydrocarbons or water depending on how it is configured. The surrounding coating is preferably formed of fine ground particles of a non-swelling polymer mixed in a solvent such as methyl-ethyl-ketone that is applied in a thin layer to the core exterior. This uncured outer layer is then contacted by a patterned surface. The patterned surface is pressed firmly against the uncured polymer/solvent mixture and transfers an inverse of the pattern to the surface of the coating. As pressure is applied, heat may also be applied to cure the coating. The resulting pattern is designed such that openings in the coating are created that regulate infiltration of water or other fluids through it and, as a result, the rate of swelling in the wellbore. Swell rate in governed in part by the ratio of the exposed area of the swelling compound to the total volume of the swelling compound. The smaller this ratio, the slower the rate of swell. The pattern created in the non-swelling layer may also provide limited mechanical restraint of the swelling element, further slowing the process.
DETAILED DESCRIPTION OF THE DRAWING
[0007] Figure 1 is a perspective view showing the element with the outer coating and the surrounding weave material.
[0008]
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT [0009] Figure 1 shows a cylindrically shaped core 10 that can be configured to be water reactive or hydrocarbon reactive. In the preferred embodiment for a water reactive version, the bulk of the core 10 is a nitrile-based polymer with incorporated water absorbing particles. One example of such materials that absorb water is referred to as super absorbing particles or SAP. These particles absorb water and swell. The result is that the rubber swells without the water or SAP being absorbed into the rubber matrix which can adversely affect its abilities to act as a seal.
[0010] Alternatively, the core can be hydrocarbon reactive and made from an oleophillic polymer that absorbs hydrocarbons into its matrix. The swelling occurs from the absorption of the hydrocarbons which also lubricates and decreases the mechanical strength of the polymer chain as it expands. EPDM is one example of such a material.
[0011] The present inventions is an effective way to delay the swelling in either type of element by placing a coating 12 that effectively adheres to the core 10 in downhole conditions. What has been discovered actually works in this environment is taking a nitrile polymer and grinding it into a powder form with particle sizes preferable smaller than 325 mesh. The powder can be mixed with a solvent such as MEK and the mixture can be referred to as "nitrile cement." The cement coating 12 is applied in a thin layer on the outside of the element 10 and allowed to dry. After it is dry a woven material 14 is tightly wrapped over the coating 12. While Figure 1 shows a spiral wrap other wrapping techniques can be used such as longitudinal strips or parallel circumferential wraps. The weave is preferably large rather than tight knit and the assembly is cured in an autoclave for an appropriate time. During the curing process, the coating 12 due to the superimposed weave material 14 will develop openings commensurate with the size of the weave. Alternatively, gaps in the coating 12 can develop which expose some area of the underlying core 10 while firmly adhering to the remainder of the core 10. This limited access area, whichever way it is provided, will limit the access of water or hydrocarbon or whatever the trigger material is that initiates swelling in the core 10. As the core 10 swells, it opens up the weave in material 14 to expose more core to fluid that makes it swell. Alternatively, the swelling of the core 10 opens bigger gaps between layers of weave material 10 and the swelling of the core 10 accelerates. [0012] The above description is illustrative of the preferred embodiment and many modifications may be made by those skilled in the art without departing from the invention whose scope is to be determined from the literal and equivalent scope of the claims below.
