    Field of invention
    [0001] The present invention generally relates to a high pressure multi-hole joint assembly and methods for completing a side well hole using the high pressure multi-hole joint assembly. History of the invention
    [0002] Well holes are typically drilled using a drill column with a drill bit attached to the lower free end and then completed by positioning a coating column inside the well hole and cementing the coating column in position. The coating increases the integrity of the well bore and provides a flow path between the surface and the selected underground formation for the injection of treatment chemicals into the surrounding formations to stimulate production, to receive a flow of hydrocarbons from the formation, and to allow the introduction of fluids for the management of the reservoir or for disposal purposes.
    [0003] A multi-hole coupling assembly is typically used during the completion of a side well bore for oil and gas production after the completion of the side well bore. During the final stages of completion of the side well hole, a multi-hole joint assembly is lowered into the well hole in the drill string to a depth where the side well hole is spaced from the main well hole. The multi-hole joint assembly typically includes a main path and a side path. The multi-hole joint assembly, therefore, can be fixed by a main path that is inserted in a completion deflector. The side path of the multi-hole joint assembly can then be positioned in the side well hole for completion and production operations. Examples of a multi-hole joint kit include Halliburton's FlexRite® and SealRite® products. However, more commercially available products, such as FlexRite® and SealRite®, either do not allow reentry either on the main path or on the side path for completion and production operations or cannot withstand wellhole pressures above 37, 23 MPa (5400 psi), due to its design and / or construction. Summary of the invention
    [0004] The present invention overcomes one or more disadvantages of the prior art by using a high pressure multi-hole joint assembly with the ability to re-enter the main path and side path to complete a side well hole under high pressure conditions.
    [0005] In one embodiment, the present invention includes a multi-pressure high pressure joint assembly, comprising: i) a body with an upper end and a lower end; ii) a tubular main path with an opening at one end for the entry of a tool or other tool, where one end of the main path has a threaded connection with the lower end of the body and increases the high pressure rating of the multi-hole joint ASSEMBLY ; and iii) a tubular side path with an opening at one end for the entry of the tool or the other tool and another opening at the other end, where the other end of the side path has a threaded connection with the lower end of the body and increases the rating pressure valve of the multi-hole coupling assembly.
    [0006] In another embodiment, the present invention includes a multi-pressure high pressure joint assembly, comprising: i) a body with an upper end and a lower end; ii) a tubular main path with an opening at one end for the entry of a tool or other tool, where the main path includes a wall with a thickness based on the outside diameter of the body that increases the high pressure rating of the set of multi-hole coupling; and iii) a tubular side path with an opening at one end for the entry of the tool or the other tool and another opening at the other end, where the side path includes a wall with a thickness based on the outside diameter of the body that increases the high pressure rating of the multi-hole joint assembly.
    [0007] In yet another configuration, the present invention includes a method for completing a side well hole, comprising: i) lowering a multi-hole joint assembly into a main well hole to a depth at which the pressure in the main well bore is about or greater than 41.37 MPa (6,000 psi), the multi-hole coupling assembly comprising a main tubular path and a lateral tubular path; ii) fixing the main path within the main well bore; iii) the positioning of the lateral path in the lateral well hole; and iv) the entry of the main path or the lateral path with a tool.
    [0008] These and other objectives, characteristics and advantages of the present invention will become apparent to those skilled in the art from the following configuration of the various embodiments and related designs. Brief description of the drawings

    [0017] In the following detailed description of the preferred configurations, references can be made to the accompanying drawings that are part of them, and in which the specific preferred embodiments where invention can be practiced are shown as an illustration. These achievements are described in sufficient detail to allow those skilled in the art to practice the invention, it should be understood that other achievements can be used and that logical changes can be made without abandoning the spirit and scope of the present invention. The subject thus claimed can also be configured in other ways, to include structures, steps and combinations similar to those described in the present, together with other present and future technologies. The following detailed description should therefore not be taken as a limitation, and the scope of the present invention is defined only by the appended claims.
    [0018] Now with reference to figure 1a, the cross-sectional view of a configuration of a high pressure multi-hole joint assembly 100 is illustrated. The multi-hole joint assembly 100 includes a body 102, a main path 112 and a side path 128. Body 102 includes an upper end 104, a lower end 106 and an outside diameter 146, which is shown in Figure 1B. The lower end 106 of the body 102 includes a main path receptacle 108 with internal threads 109 and a side path receptacle 110 with internal threads 111. The threaded connections of the various components of the high pressure multi-hole joint configuration described herein are oriented, without limitation, to internal threads or specific external threads described for each component and may include internal threads instead of external threads or external threads instead of internal threads based on the preferred construction of the components of each configuration.
    [0019] The main path 112 includes an opening 114 at one end for the entry of a tool, being closed at the other end 116. The main path 112 also includes an inner diameter, an outer diameter and a wall with a thickness based on the diameter outer 146 of the body 102. External threads 118 at one end of the main path 112 make up the threaded connection with the internal threads 109 in the main path receptacle 108 of the body 102, which can increase the high pressure rating of the multi-hole joint 100 The main path 112 can include multiple components as illustrated in figure 1a which include threaded connections between the external threads 120, 126 and the internal threads 122, 124-respectively. The threaded connections of the various components that make up the main path 112, therefore, can also increase the high pressure rating of the multi-hole joint assembly 100. In addition, the tubular design of the main path wall 112 can further increase the high pressure rating of the multi-hole joint assembly 100.
    [0020] The side path 128 includes an opening 130 at one end for the entry of a tool and another opening 132 at the other end. The lateral path 128 also includes an internal diameter, an external diameter and a wall with a thickness based on the outer diameter 146 of the body 102. External threads 134 at the other end of the lateral path 128 make up the threaded connection with the internal threads 111 in the receptacle the side path 110 of the body 102, which can increase the high pressure rating of the multi-hole joint assembly 100. The side path 128 can include multiple components as shown in figure 1a which include threaded connections between the external threads 136, 142 and the internal threads 138, 140 - respectively. The threaded connections of the various components that make up the side path 128, therefore can also increase the high pressure rating of the multi-hole joint assembly 100. In addition, the tubular design and the wall of the side path 128 can further increase the high pressure rating of the multi-hole joint assembly 100. Although the inside diameter of the side path 128 is greater than the inside diameter of the main path 112, as shown in Figure 1a, the inside diameter of the side path 128 can be smaller or the same as the inside diameter main route 112.
    [0021] The body 102 of the multi-hole joint assembly 100 may also include a deflector 144 positioned within the body 102 to selectively direct a tool to the main path 112 or to the side path 128 based on the diameter of the tool. If the diameter of the tool is less than the inside diameter of the main path 112, then the same tool can be used to enter opening 114 of main path 112 and opening 130 of side path 128. In this case, the tool can be directed to enter the opening 114 of the main path 112 by orienting the multi-hole joint assembly 100 and / or the tool so that gravity directs the tool to the lower opening 114 of the main path 112. If, however, the diameter of the tool is larger than the main path internal diameter 112, then another tool may be preferred to enter only opening 130 of side path 128. In this case, the tool passes through deflector 144 into an opening 130 of side path 128.
    [0022] As illustrated in figure lB, which is a cross-sectional view of the high-pressure multi-hole joint assembly 100 along lB-lB in figure lA, the combined outer diameter of the main path 112 and the outer diameter of the side path 128 do not they are larger than the outer diameter 146 of the body 102. As a result, the multi-hole joint assembly 100 has no welded connection that could impair its ability to freely pass through a well bore lined with a column.
    [0023] As illustrated in figure lC, which is a cross-sectional view of the high pressure multi-hole joint assembly 100 along lC-lC in figure lA, a stabilizer 148 can be connected to the main path 112 using screws 152, which include a opening 150 for receiving side path 128. Alternatively, the stabilizer can be connected to side path 128 and includes an opening for receiving main path 112.
    [0024] Now with reference to figure 2A, the cross-sectional view of another configuration of a high-pressure multi-hole joint assembly 200 is illustrated. The multi-hole joint assembly 200 includes a body 202, a main path 212 and a side path 228. The body 202 includes an upper end 204, a lower end 206 and an outer diameter 246, which is illustrated in figure 2B. The lower end 206 of the body 202 includes a main path receptacle. 208 with internal threads 209 and a side-path receptacle 210 with internal threads 211.
    [0025] The main path 212 includes an opening 214 at one end for the entry of a tool, being closed at the other end 216. The main path 212 also includes an inner diameter, an outer diameter and a wall with a thickness based on the diameter outer body 246 of the body 202. Outer threads 218 at one end of the main path 212 comprise the threaded connection with the internal threads 209 and the main path receptacle 208 of the body 202, which can increase the rating of the high pressure multi-hole joint assembly 200. The main path 212 can include multiple components as illustrated in figure 2A, which includes threaded connections between the external threads 220, 225 and the internal threads 222, 224-respectively. Compared to figure 1a, the main path 212 includes other components with threaded connections between the external threads 226 and the internal threads 227. The threaded connections of the various components that make up the main path 212, therefore, can also increase the high pressure rating of the multi-hole joint assembly 200. In addition, the tubular design and the main path wall 212 can also increase the high pressure rating of the multi-hole joint assembly 200.
    [0026] Side path 228 includes an opening 230 at one end for the entry of a tool and another opening 232 at the other end. The lateral path 228 also includes an internal diameter, an external diameter and a wall with a thickness based on the external diameter 246 of the body 202. External threads 234 on one of the lateral supports 228 make up the threaded connection with the internal threads 211 on the receptacle of the side path 210 of body 202, which can increase the high pressure rating of the multi-hole joint assembly 200. side path 228 can also have multiple components as shown in figure 2A that include threaded connections between the external threads 236, 242, and the internal threads 238, 240 - respectively. The threaded connections of the various components that are part of the side path 228, therefore, can also increase the high pressure rating of the multi-hole joint assembly 200. In addition, the tubular design and wall of the side path 228 can further increase the rating of high pressure of the multi-hole joint assembly 200. Although the inside diameter of the side path 228 is larger than the inside diameter of the main path 212, as shown in figure 2A, the inside diameter of the side path 228 can be smaller or the same as the main path internal diameter 212.
    [0027] The body 202 of the multi-hole joint assembly 200 may also include a baffle 244 positioned within the body 202 to selectively direct a tool to main path 212 or side path 228 based on the diameter of the tool. If the diameter of the tool is smaller than the inside diameter of the main path 212, then the same tool can be used to access the opening 214 of the main path 212 and the opening 230 of the side path 228. In this case, the tool can be directed to access the opening 214 of the main path 212 by orienting the multi-hole joint assembly 200 and / or the tool so that gravity directs the tool to the lower opening 214 of the main path 212. If, however, the diameter of the tool is larger than the main path internal diameter 212, then another tool may be preferred to access only the opening 230 of the side path 228. In this case, the tool crosses the baffle 244 in the opening 230 of the side path 228.
    [0028] As illustrated in figure 2B, which is a cross-sectional view of the high pressure multi-hole joint assembly 200 along 2B-2B in figure 2B, the combined outside diameter of the main path 212 and the outside diameter of the side path 228 do not they are larger than the outer diameter 246 of the body 202. As a result, the multi-hole coupling assembly 200 does not include welded connections that could impair its ability to freely cross a well bore lined with the column.
    [0029] As illustrated in figure 2C, which is a cross-sectional view of the multi-pressure high-pressure joint assembly 200 along 2C-2C in figure 2A, the main path 212 includes a stabilizer 248 with an opening 250 for receiving the path side 228. Although this is the preferred configuration, side path 228 can include the stabilizer with an opening for receiving main path 212.
    [0030] The high pressure multi-hole joint set described herein can be used to finish a side well hole as described with reference to figure 3. The high pressure multi-hole joint set 300 is lowered into a well hole main to a depth where the pressure in the main well bore is about, or greater than, 41.37 MPa (6000 psi). The multi-hole coupling assembly 300 includes a substantially tubular main path 312 and a substantially tubular side path 328. The main path 312 is fixed within the main well hole using a completion baffle that can be positioned in the main well hole below the hole side well for fixing main path 312. Side path 328 is positioned in the side well hole, where main path 312 and / or side path 328 can be accessed with a tool for completion and production operations. The side path 328 can be selectively accessed or re-accessed with a tool using a baffle 344 to deflect the tool within the side path 328 based on the diameter of the tool.
    [0031] The main path 312 can be stabilized in relation to the side path 328 with a stabilizer as a multi-hole joint assembly 300 is lowered into the main well hole. In figure 3, there are three separate stabilizers, 348, 358, and 368. The stabilizer 348 can be positioned near an upper end 304 of the multi-hole joint assembly 300. Each stabilizer 348, 358, 368 stabilizes the main path 312 relative to the path side 328 when the multi-hole coupling assembly 300 is lowered into the main well hole. Each stabilizer 348, 358, and 368 is connected to main path 312 with an opening for receiving side path 328. Alternatively, each stabilizer can be connected to side path 328 with an opening for receiving main path 312 or the path main 312 may include each stabilizer 348, 358, 368 as described with reference to figure 2C. Providing other stabilizers, the main path 312 and side path 328 can be kept in alignment, without flexing, when the multi-hole joint assembly 300 is rotated and lowered into the main well hole. Each stabilizer 348, 358, 368 also helps to maintain side path 328 on the top side and main path 312 on the bottom side, which is preferred.
    [0032] Although they have been illustrated and described in the present specific configuration, it will be appreciated by the technicians in the subject that any arrangement that is calculated to achieve the same purpose can be replaced by the achievements shown. This application is intended to cover all adaptations or variations of the present invention. Therefore, it is manifestly intended that the present invention is limited only by the following claims and their equivalents.
