  • Patent number: 8342334
    Abstract: An improved cornerboard that is usable to protect a corner of a shipping container is provided. The cornerboard reduces workforce required to secure the cornerboard to a plurality of shipping containers, such as a pallet of shipping containers. For example, the cornerboard permits a single individual to position cornerboards about the pallet of shipping containers and shrink wrap or otherwise secure the shipping containers with the cornerboards. In an embodiment, the cornerboard has a tab portion that is partially separable form the cornerboard and positionable between two shipping containers to prevent movement of the cornerboard and eliminate the need for an individual to hold the cornerboard.

  • Patent number: 8165817
    Abstract: A method for estimating properties of fluids in rock formations at selected locations within a geologic basin includes generating an initial model of the basin. The model includes as output spatial distribution of a rock formation mineral composition, rock formation porosity and composition of fluids in the rock formation porosity. An initial estimate of fluid composition is generated for a rock formation, and a sample of fluid is extracted from pore spaces of the rock formation. Composition of the fluid sample is analyzed from within, and the initial model of the basin is adjusted to substantially match the analyzed fluid composition. The adjusted model is used to generate an initial estimate of fluid composition.
