    摘要: This invention relates to the construction of well such as oil and gas wells using techniques based on drilling small lateral wells from a main well. The problem of narrow pressure window is solved by the use of constructions techniques that are based on the use of lateral boreholes, i.e. secondary boreholes that are drilled a main borehole, wherein a method of constructing a well comprises drilling a main borehole extending from the surface through one or more underground formations, drilling a plurality of lateral boreholes extending from the main borehole into surrounding formations, wherein the lateral boreholes are substantially shorter and of smaller diameter than the main borehole; and wherein each lateral borehole is separated from its neighboring lateral boreholes by a relatively short distance. Drilling of the lateral boreholes can be for to extend 5-60 meters from the main borehole with a diameter in the range 3.8-10 cm by the lateral boreholes at an axial spacing of less than a few meters in the main borehole. Drilling of more than one lateral borehole can be done at the same depth in the main borehole with a trajectory that deviates from the main borehole by less than 10° or with trajectories that extend in a plane that does not contain the main borehole.

    摘要: An apparatus for modifying the wall surface of a borehole drilled through an underground formation. The apparatus comprises a tool body that can be introduced into the borehole using a conveyance system so as to be moveable along the borehole, and one or more members arranged so as to be able to be urged against, and moved across at least part of the borehole wall in order to work the surface thereof and modify its properties. A method of modifying the wall surface comprises positioning the tool body in the borehole at a location of interest using the conveyance system, urging the members against the borehole wall with sufficient force to modify the properties of the surface thereof, and moving the members across the surface of the borehole wall.
