A deflection device keeps high velocity gravel slurry flow from directly impinging the wellbore wall in open hole and breaking loose the filter cake coating on the wall or, in a cased hole, prevents the direct impingement of gravel slurry on the casing which can cause wear from erosion. The slurry exist from an intermediate annulus in a crossover that is fitted with movable members that can be pivotally mounted for rotational displacement by the pumped slurry to act as a deflector to prevent or minimize direct impingement on the wellbore wall or casing. When the flow stops the deflectors can pivot back to their original positions. The deflectors can be simply replaced when worn.

Description

APPLICATION FOR PATENT
Title: Frac-Pack Casing Saver
Inventor: Nicholas J. Clem
FIELD OF THE INVENTION
[0001] The field of this invention relates to gravel delivery systems involving crossovers where the delivery rates are elevated to compensate for highly unconsolidated formations.
BACKGROUND OF THE INVENTION
[0002] Gravel packing is the technique of depositing proppant or sand in perforations to promote production and to slow the production of particulates from the formation as the hydrocarbons are produced. In the case of unconsolidated formation with relatively high permeability, much of the fluid used to circulate the gravel can be absorbed by the formation when gravel is delivered. To compensate for this fluid loss and to be able to also frac the formation as the gravel is delivered, the pumping rate has been greatly stepped up. While operations in more consolidated formations could result in an adequate frac job with about 15 barrels a minute flow rate, flow rates in the order of 65 barrels per minute or more are not unusual when dealing with a fairly unconsolidated formation.
[0003] In a typical installation, the gravel slurry is delivered down the tubing and goes through a packer and into a cross-over and into an inner annulus. The slurry from there has to make a radial exit due to the equipment configuration to get to the outer annulus that is the wellbore. If the well is cased at that point the slurry exit velocities at the higher pumping rates required in unconsolidated formations has in the past caused erosion problems where the slurry makes initial impact after exiting the openings from the inner annulus, as illustrated in Figure 4. Additionally, if the well is open hole, the high fluid velocities make the filter cake on the wellbore wall come off. This is also not desirable as the gravel and fluid would tend to go into the formation at that location rather than further along the wellbore. Alternatively the filter cake can plug the gravel pack and impede subsequent production.
[0004] The present invention addresses the harm from high pumping rates of gravel slurry in unconsolidated formations by deflecting the exiting gravel flow away from the casing or borehole wall to reduce or eliminate the erosive effects from high impact of slurry. The deflection device also acts to improve impingement angles downstream which also can reduce the erosion of the casing or the removal of filter cake in open hole. The deflecting device is simple to fabricate and takes the brunt of the erosion effects from high velocity slurry impinging it. These and other aspects of the present invention can be more readily understood from a review of the description of the preferred embodiment that appears below along with the associated drawings. The claims at the end of the application are understood to define the full scope of the invention.
SUMMARY OF THE INVENTION
[0005] A deflection device keeps high velocity gravel slurry flow from directly impinging the wellbore wall in open hole and breaking loose the filter cake coating on the wall or, in a cased hole, prevents the direct impingement of gravel slurry on the casing which can cause wear from erosion. The slurry exist from an intermediate annulus in a crossover that is fitted with movable members that can be pivotally mounted for rotational displacement by the pumped slurry to act as a deflector to prevent or minimize direct impingement on the wellbore wall or casing. When the flow stops the deflectors can pivot back to their original positions. The deflectors can be simply replaced when worn.
BRIEF DESCRIPTION OF THE DRAWINGS
[0006] Figure 1 shows the deflectors in a closed position inside of casing;
[0007] Figure 2 is the view of Figure 1 with the deflectors in the open position;
[0008] Figure 3 shows a crossover with the deflector pushed open by flow; and [0009] Figure 4 shows the damage that can happen without the deflector at high slurry flow rates.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0010] Figure 1 illustrates a tubular shape 10 that defines the inner annulus from a crossover 11 shown in Figure 3, through which the gravel slurry travels after coming down a tubing string (not shown) and through a packer (not shown). These components are omitted because they are well known to those skilled in the art and the Figures focus on the modification to such equipment that addresses the issue of erosion of a surrounding casing or wellbore, either of which is shown as 12 surrounding the tubular 10. Tubular 10 has one or a plurality of outlets 14 that are normally covered, when there is no slurry flow through the crossover, by deflection members 16. Preferably members 16 on their outer surface 18 take the curvature of the tubular 10 so that surface 18 becomes approximately the continuation of the outer surface 20 of the tubular 10. Deflection or diverter member 16 is preferably pivotally mounted at pin 22 that is more easily seen in Figure 2. It can have a generally trapezoidal shape. Its own weight can keep it in the closed position of Figure 1. Arrow 24 illustrates pumped slurry exiting opening 14 and striking the deflection member 16 in a generally radial direction. In response, the deflection member through a panhandle 21 pivots on pin 22 to allow the slurry flow represented by arrow 26 to change direction from generally radial at arrow 24 to generally axial and in approximately the direction of the wellbore wall 30. Those skilled in the art will appreciate that this reorientation of the slurry stream reduces or eliminates direct slurry impingement at high velocity in a nearly radial direction against the wellbore wall 30 regardless of whether that is filter cake from drilling in an open hole or the inner wall of a tubular or casing in a cased or lined borehole. The gravel 23 is left outside the screen 25 while the filtered fluid 27 returns to the crossover 11 as indicated by arrows 29.
[0011] Deflection members 16 may be made from a hardened material or coated with a hardened material to improve service life. The hardened material can cover the inside surface 32 and may be removable for rapid change without a need to replace the entire deflection member 16 which can then be made from a cheaper material. Carbide or composite materials could be used for a more durable surface that receives the impinging slurry flow.
[0012] Alternative designs are envisioned. The deflection members 16 can be fixedly mounted in a spaced relation to the openings 14 and can be mounted in such a way as to allow rapid replacement, when needed. It will be recognized that this alternative design enlarges the clearance needed to run the tool and further creates a potential for damage during run in. In the embodiment of Figures 1 and 2 the deflection devices 16 become a continuation of the outer surface 20 of the tubular 10. To insure that the deflection devices stay in the Figure 1 position during run in a band spring can be mounted on an exterior groove on the deflection devices 16. Alternatively, a spring can be fitted on the pin 22 akin to the application seen on flapper closures in subsurface safety valves. Yet another option is to hold the deflection members 16 shut for run in with a breakable member and simple start slurry pumping and use pump pressure to break the closure device so that pivoting action can occur.
[0013] For greater stability in the open position, outer face 28 on the deflection member 16 can be presented at an angle that promotes as close to a flush contact as possible with surface 30 considering the pivoting action about pin 22. Optionally, a seal member can be fitted to the edges of the deflection member 16 to prevent or minimize flow in either direction past the deflection member 16 when in the Figure 1 position.
[0014] Yet another alternative design is to guide the deflection members 16 so that they may lay flush for run in as shown in Figure 1 but under pressure from the slurry circulation pumps at the surface the deflection members will move along guides in a generally radial direction all around so that they don't cock at the wrong angle. While it is preferred that the deflection angle redirect the slurry flow in a downhole direction to reach the area of interest below the packer, a deflection device that is radially movable while still parallel to the tubular 10 will still protect the wellbore 12 but may allow some of the slurry to flow uphole. A fixed deflection device at a distance from the opem'ng 14 should preferably be slanted to direct the slurry flow downhole along the wellbore wall 30. Even a guided design for the deflection member 16 can ensure that the downhole end moves more than the uphole end so as to approximate the performance of the pivoting design shown in Figures 1 and 2.
[0015] The above description is illustrative of the preferred embodiment and various alternatives and is not intended to embody the broadest scope of the invention, which is determined from the claims appended below, and properly given their full scope literally and equivalently.
