Abstract: A method of preventing or controlling the loss of well drilling fluid into the pores and fractures of subterranean rock formations by the addition of resilient graphitic carbon particles to the drilling fluid in sufficient amounts to plug the pores and fractures. The graphitic carbon material reduces loss of circulation, lowers torque and drag, prevents casing wear while drilling, and provides a new method for the controlled release of graphite at extreme pressure. The material is non-toxic and imparts the well-known lubricating properties of graphite without contributing to surface sheen development under US EPA offshore cuttings discharge rules.

Abstract: A method of consolidating particulate materials or combinations of such materials into shaped products of very low porosity. High compaction pressures are applied at temperatures in the range of sintering temperature of the materials being consolidated to achieve essentially complete densification at extremely rapid processing rates. Electrothermal heating is utilized to accomplish these results. Difficult materials such as silicon carbide, boron carbide and other very high melting point materials may be densified by these techniques.

Abstract: A method and apparatus for high temperature treatment of petroleum coke. In the method, calcined petroleum coke, preferably hot, is introduced into a graphitizing zone and heated by direct electrical resistance. The coke is continuously agitated. If it is desired to desulfurize the coke, it is heated to at least about 1,700*C, while graphitization requires a temperature of at least about 2,200*C. The apparatus comprises means defining a heating zone having petroleum coke input means communicating with an upper portion thereof and at least one electrode in an upper portion thereof. Means defining a tempering and cooling zone are positioned below the heating zone and an agitator, forming an electrode, is positioned at the bottom of the heating zone and mounted for rotation in a horizontal plane. The agitator has at least one aperture which provides communication between the heating zone and the tempering and cooling zone.

Abstract: An improved ground covering and heating means is constructed by formulating graphited concrete containing about 35-85 percent graphite, based on the weight of the dry mix. The concrete is laid in combination with a suitable heating element beneath the upper surface. In the preferred embodiment, the graphited concrete is sandwiched with a lower layer of nongraphited concrete for added strength. In preparing the sandwich, the graphited concrete is preferably poured over the nongraphited concrete while the latter is still in a green state.

Abstract: A carbonaceous particulate material is provided that is characterized by having a reversible volumetric expansion/contraction in fluid media (“VR”) of greater than or equal to (≧)3% between 4,000 psi and 10,000 psi. The porous carbonaceous particulate material of the present disclosure is also characterized by having a true density, (“PT”), of 1.2 g/cc≦PT≦2.0 g/cc, when milled to −200 mesh and has a d50 particle size distribution of about 15 μm. This is the consequence of the instant material exhibiting a high level of closed porosity with very small pores, in contrast with prior art materials that would have a wider range pore sizes for the closed pores.
