Abstract: Methods and systems relate to in situ combustion utilizing configurations of injection and production wells to facilitate the in situ combustion. The wells define vertically deviated lengths that have different orientations from one another. Further, heating processes such as resistive heating and cyclic steam stimulation may take place in one or both of the injection and production wells to precondition a reservoir prior to the in situ combustion.

Abstract: Methods and apparatus relate to in situ combustion. Configurations of injection and production wells facilitate the in situ combustion. A first production well disposed in a first oil bearing reservoir is spaced from a second production well disposed in a second oil bearing reservoir separated from the first oil bearing reservoir by a stratum having lower permeability than the first and second oil bearing reservoirs. The stratum isolates one of the first and second production wells from one of the first and second oil bearing reservoirs. In situ combustion through the first oil bearing reservoir generates heat that irradiates into the second oil bearing reservoir to enable producing hydrocarbon with the second production well.

Abstract: A hangtag is provided that is capable of hanging and securing a tool, such as a socket. The hangtag has a body portion having a front surface and a back surface, a hanging mechanism connected to the body portion, and a tool supporting mechanism also connected to the body portion for supporting a tool. The tool supporting mechanism includes first and second legs and a locking finger disposed between the first and second legs. The locking mechanism allows the particular tool to be reattached to the hangtag assembly after it is initially unlocked. This allows the hangtag to function as a storage and organization device for the tool.

Abstract: A saw blade incorporates an integrated cant angle. The saw blade includes a cutting portion having a toothed edge and opposite edge. The toothed edge defines a cutting plane. A shank portion extends from the cutting portion and is laterally offset from the opposite edge of the cutting portion defining a step thereat. The shank includes an end portion including a mounting edge, the mounting edge and step define a mounting plane which is angularly offset from the cutting plane.

Abstract: An apparatus for securing a tool to a hangtag is provided. A method for securing the tool is also provided. In one embodiment, the invention pertains to a hangtag assembly that includes a fastening mechanism for securing a tool having a shank portion, such as a socket driver. The hangtag has a body portion, and a hanging mechanism connected to the body portion. The hangtag also has a tool fastening mechanism for securely attaching a tool to the hangtag. The tool fastening mechanism includes one or more pairs of through-openings, and one or more ties, wherein each tie is wove around the shank of the tool and through a respective pair of through-openings. In another embodiment, the invention pertains to a hangtag assembly that includes a fastening mechanism for securing a circular tool having a centrally located hub portion defining an opening therethrough. The hangtag has a body portion with a plurality of apertures therethrough and a tool fastening mechanism for securely attaching a tool to the hangtag.

Abstract: A hangtag is provided that is capable of hanging and securing a tool, such as socket. The invention pertains to a hangtag mechanism that includes a locking mechanism for securing a socket style tool. The hangtag has a body portion having a front surface and a back surface, a hanging mechanism connected to the body portion, and a tool supporting mechanism also connected to the body portion for supporting a tool. The tool supporting mechanism includes first and second legs and a locking finger disposed between the first and second legs. The locking mechanism allows the particular tool to be reattached to the hangtag assembly after it is initially unlocked. This allows the hangtag to function as a storage and organization device for the tool.

Abstract: A hangtag is provided that is capable of hanging multiple tools. The hangtag has a body portion, a hanging mechanism connected to the body portion, and a tool supporting mechanism also connected to the body portion for supporting a tool. The body portion has a front surface and a back surface. On the back surface is disposed a hangtag attachment apparatus. The hangtag attachment apparatus comprises a bracket, and an elongated attachment bar configured to be selectively attached to and detached from the bracket. The attachment bar has a length that permits it to be connected to at least two and preferably more hangtags so that multiple hangtags may be selectively connected together. In this way, tools that would otherwise be sold individually can now be sold as a set.

Abstract: A laser level disposable on a reference surface includes a housing, a pendulum pivotably connected to the housing, a first laser diode disposed on the pendulum for emitting a first laser beam along a first path, and a lens disposed on the pendulum in the first path for converting the first laser beam into a first planar beam, the first planar beam forming a line on the reference surface.
