Abstract: A method and apparatus for milling and/or broaching within a wellbore. A flexible broach runs into the wellbore and is located adjacent a portion of the wellbore to be broached. The broach reciprocates axially within the wellbore and removes at least part of the portion to be broached. Weight may be coupled to the broach, thereby applying a resultant side load for broaching an offset portion of the wellbore. The broach comprises a flexible member that may be a bare cable. When an abrasive material is disposed on an outer surface of the flexible member, the flexible member may be a cable, a continuous rod, or pressurized coiled tubing. Alternatively, sleeves positioned on the flexible member may have an abrasive material on their outer surface. A rotational mill that is either coupled to the broach or run in separately from the broach can further mill the wellbore.

Abstract: Our invention concerns spreadable and/or spoonable water continuous, gelatin free cream alternatives comprising 10 to 50 wt % of a fat blend and up to 5 wt % of a biopolymer other than gelatin as a thickener, in addition to water as continuous phase, which creams display a Stevens value at 5° C. (S5) of more than 100 gram, while the fat blend comprises vegetable fat(s) and 5 to 75 wt % of dairy fat and which fat blend displays a solid fat index (NMR-Pulse on stabilised fat) at 5° C. (N5) and at 15° C. (N15) such that the ratio between N15 and N5 (i.e. N15/N5) is less than 0.60.

Abstract: The apparatus is a whipstock assembly for use in a wellbore to form a lateral wellbore therefrom. In one aspect, a whipstock is attached to a cutting tool by a shearable connection whereby the whipstock and cutting tool assembly may be run into the wellbore simultaneously. The shearable connection is designed to fail in compression while being able to withstand forces in tension brought about by the whipstock, accessories and extensions required to properly place the whipstock above a preset packer in the wellbore. The shearable connection means consists of two sets of shearable members, one set provides equal shear resistance in tension and in compression, another set provides shear resistance in tension, but not in compression. The resulting connection is stronger in tension than in compression and failure of the connection due to the weight of the whipstock assembly is less likely.

Abstract: The present invention discloses a whipstock assembly for use in a wellbore to form a lateral wellbore therefrom. In one aspect, a whipstock is attached to a cutting tool by a shearable connection whereby the whipstock and cutting tool assembly may be run into the wellbore simultaneously. Upon compressive force from above, the shearable connection fails and the cutting action can begin. The shearable connection is designed to fail in compression but to withstand forces in tension brought about by the whipstock, accessories and extensions required to properly place the whipstock above a preset packer in the wellbore. In one aspect, the shearable connection means provides a first set of shearable members with equal shear resistance in tension and in compression. Another set of shearable members provide shear resistance against tensile forces but do not provide shear resistance against compressive forces.
