Definitions
- the present invention relates generally to an improved method for drilling multi-lateral wells and related device. More particularly, the present invention relates to an improved method for drilling one or more multi-lateral wells from an existing well whereby the junction about the lateral well is sealed.
- Drilling or utilizing multi-lateral or horizontal wells has become increasingly popular for enhancing production and recovery of oil and gas from well-bores.
- Multi-lateral drilling methods have become increasingly popular for enhancing production and recovery of oil and gas from well-bores.
- Multi-lateral wells have been found very effective in areas where the pay-zone or
- oil/gas deposit may be thin or hard to reach with standard down-hole drilling operations.
- one of the primary reasons an operator would drill a multi-lateral well is to take advantage of the existence of a previously drilled wellbore. In drilling a multi-lateral well, a

- the art field is in search of a method to drill a lateral well and to establish
- a sealed junction about one portion of the lateral well, such as between the lateral well and the

- Another difficulty encountered with the prior art method disclosed in the '503 patent is the practical impossibility of the method to effectually warranty the seal of the junction with the passage of time.
- the method discloses using conventional techniques to cement about the junction, such as flowing cement into the well-bore and allowing the cement to fill the interstices
- the art field desires a method that effectively fills the area where a junction is to be

- Fig. 1 generally describes an area where a lateral well is desired.
- the figure is illustrative of a well that is completed with steel casing 1 and cement 2 around well-bore 3.
- the manner of selection of an area to drill a lateral well-bore may be by any means common in the art, however, most typically the selected location is where an operator desires to drill a new well, drill to a new target.
- this list is not exhaustive and there are numerous other reasons an operator may
- the area selected for the lateral well is generally defined as

- Section milling is common in the art. However, an exemplary section milling operation
- the 3 may include the steps of lowering a drill string 7 into the well bore 3, the drill string 7 having a conventional section mill 8 operateably attached about the drill string 7.
- the section mill 8 will be stopped above the preselected location 6 and begin
- the section milling may and should cause the section mill 8 to engage the casing 1 and destroy substantially all of the casing 1 about the pre-selected location
- An operator may thus lower the drill string 7 to a point below the preselected point while keeping the section mill engaged thereby destroying or removing the casing from a point above the preselected location 6 to a point below the preselected location 6. After completion of the section milling step, the operator should have removed substantially all of the casing along location 6.

- Embodiments of the present invention are designed for establishing a
- the present invention utilizes an under-reamed area that is only about two to 2.5 times the
- FIG. 3a an illustration of an embodiment of the present inventions under-reaming
- well -bore width 13 is only enlarged to under-reamed width 12.
- width 12 to borehole width 13 is about 2.0 to 2.5 whereas prior art ratios and ratios of
- borehole width 13 is about 3.5. Accordingly, embodiments of the present invention do not require as much of an under-reaming operation. As previously discussed, a large under-reaming
- borehole width 13 is about two to 2.5.

- an embodiment with a straight guide 27 an embodiment with a straight guide 27, an
- inflatable packer element 19 may also be utilized.
- a cement 41 material has been injected into the well-bore to fill about the preselected location 6, it may be observed that a guide 26 still defines an arcuate path and the cement 41 has completely filled about the pre-bent guide.
- Another embodiment utilizes an epoxy cement material produced from apumpable material of epichlorohydrin and bisphenol that hardens after

- the inflatable packer 18 is
- the inflatable packer 18 is preferably about the pre-bent guide 26 in the area of preselected
- packers may be inflated (not shown) such that the inflation completely fills the under-reamed area.
- Inflation of packers is common in the art and may be accomplished as known in the art.
- a typical method of inflating a packer pumps cement or other substance into the packer to inflate, a preferred substance is an epoxy resin such as an armoured epoxy.
- inflatable packer 18 on the pre-bent guide 26 will ensure that upon inflation no contaminant from the formation will become mixed with the cement and reduce the hardening of the material and sealing effect about the junction and also will ensure that the under-reamed cavity is substantially filled with a cement or epoxy resin material.
