US Classification:

166268, 166 50, 166369, 175 61

Abstract:

The system of subterranean wells includes a subsurface flow line having at least a portion within or underlining one or more subterranean formations. One or more drainage wells , and each extend from the surface and intercept at least one of the subterranean formations at a respective interception location. A lower portion of each drainage well is in fluid communication with the subsurface flow line. A recovery well extends from the surface and is also in fluid communication with the subsurface flow line, so that fluids entering the drainage well flow into the subsurface flow line and then into the recovery well.

US Classification:

166306, 175 78, 175 61

Abstract:

Systems and methods for multi-lateral wellbore construction and stimulation from cased parent wellbores. Methods and apparatus are provided to facilitate the creation of casing exit openings in the casing of parent wellbores. Methods and systems are provided for azimuthally and longitudinally aligning drilling assemblies through openings in a parent wellbore casing are provided to allow for drilling multiple lateral wellbores extending outwardly from a parent wellbore. A method of stimulating one or more subterranean zones intersected by multiple lateral wellbores extending outwardly from one or more patent wellbores includes the steps of: simultaneously injecting a stimulation fluid into the lateral wellbores; and stimulating the zones intersected by the lateral wellbores in response to the stimulation fluid injecting step.

Inventors:

Stephen A. Graham - Bellaire TX

Assignee:

Natural Reserves Group, Inc. - Houston TX

International Classification:

E21B 2303

US Classification:

166313

Abstract:

In a well having at least one deviated wellbore drilled as an extension of a primary wellbore, a method and apparatus are disclosed for selectively re-entering a deviated wellbore. The method comprises running a diverter assembly into the primary wellbore proximate the opening at the junction of the primary wellbore and the deviated wellbore, aligning the diverter assembly having an upper whipstock member having a diverter face to position the diverter face to facilitate diversion of tools for re-entry into the deviated wellbore, and anchoring the diverter assembly in the primary wellbore.

Appl. No.:

8/534695

Inventors:

Stephen A. Graham - Bellaire TX

Assignee:

Natural Reserves Group, Inc. - Houston TX

International Classification:

E21B 708
E21B 2314

US Classification:

166313

Abstract:

In a cased wellbore having one or more cased and cemented drainholes extending therefrom such that the elliptical shaped opening or junction of each drainhole with the primary well is sealed and cut flush with the inside of the primary well casing, an inventive method is disclosed for: (a) isolating each perforated and/or drainhole completion within the primary wellbore, (b) providing flow control means for each completion to permit selective testing, stimulation, production, or abandonment, and (c) facilitating selective re-entry into any cased drainhole for conducting additional drilling, completion, or remedial work. In a preferred embodiment, a production liner is permanently attached within the primary well casing such that packers straddle permanent flow control devices and precut liner windows which are positioned adjacent to perforated completions and drainhole entrance openings, respectively. Orientation key slots built into internal seal bore/latch down profile collars positioned below each precut window are used in conjunction with a novel wireline conveyed video camera tool to properly align the base of each precut liner window to the bottom of each elliptical shaped drainhole opening.

Appl. No.:

7/943448

Inventors:

Stephen A. Graham - Bellaire TX

Assignee:

Natural Reserves Group, Inc. - Houston TX

International Classification:

E21B 706

US Classification:

175 61

Abstract:

A horizontal bore hole is sidetracked through a window cut in a cased vertical well or from a vertical open hole shaft extending below the kickoff point. In one embodiment, a whipstock is used. In another embodiment, the cased vertical well provides a drillable joint so the window can be cut with a conventional bent housing mud motor from a cement plug located adjacent the drillable joint at the kickoff point. In yet another embodiment, a cement plug is dressed down to the kickoff point in a vertical open hole and is used to start the curved well bore. After drilling at least the curved bore hole, a production string extending into the vertical well is cemented in the curved bore hole and then cut off inside the vertical cased hole with a conventional burning shoe/wash pipe assembly. The whipstock or cement plug is removed to clear the vertical well to a location below the entry of the horizontal well bore. Multiple horizontal wells may be drilled.

Abstract:

Aqueous dispersions useful in adhesive and coating applications, and a method of preparing the same. The dispersion contains (a) an ethylene interpolymer having an acid number of at least 117, a melt flow of at least 50, and comprising from 15 to 24 percent by weight of the interpolymer of interpolymerized ethylenically unsaturated carboxylic acid, such as acrylic or methacrylic acid, (b) from about 5 to about 2,000 parts by weight per 100 parts of the interpolymer of a rosin tackifier having an acid number of at least about 76 and being compatible and codispersible with the interpolymer, (c) water in an amount sufficient to provide a solids content of the dispersion of from about 10 to about 60 percent, and (d) water soluble alkali in an amount effective to neutralize from 20 to 130 percent of the acid groups in the interpolymer and the tackifier, to disperse at least 99 percent by weight of the interpolymer and the tackifier, and to provide a viscosity of the dispersion which is less than about 1,500 Pa-s. The dispersion is prepared by heating and agitating a mixture of the ingredients sufficiently to disperse at least about 99 weight percent of the interpolymer and the tackifier.
