Macro Velocity Model Estimation Through Model-based Globally-optimized Residual-curvature Analysis

Abstract: In the past few years, significant progress has been made on new velocity analysis algorithms. In the first part of this paper, we will briefly summarize recent advances on velocity analysis. Then we describe a new model-based globally-optimized residual curvature analysis algorithm we have just developed. Like conventional residual curvature analysis, the algorithm is based on the principle that after prestack migration with a correct velocity model, an image in the common image point (CIP) gather is aligned horizontally regardless of structure. Unlike conventional residual curvature analysis, this algorithm uses not only the interpreted CIP gathers, but also the interpreted migrated depth section as input. The algorithm is model-based, and uses modelbased CIP ray tracing to relate residual moveouts in CIP gathers to errors in the velocity model. Residual moveouts measured in CIP gathers are globally used in the optimization process for updating the whole velocity model. Also model-based normal incident ray tracing is used for updating the reflector boundaries.

Oriented multilayer heat sealable packaging film

Abstract: An oriented heat sealable multilayer structure. The structure comprises a substrate having a first surface and a second surface, the substrate comprising a polyolefin film; a polymeric heat sealable layer on the first surface of the substrate, the layer comprising a polymeric material selected from the group consisting of a terpolymer of ethylene, propylene and butene-1, a random copolymer of ethylene and propylene, and blends thereof; a primer coating on the second surface of the substrate; and a water vapor and gas barrier layer on the primer coating, the water vapor and gas barrier layer selected from the group consisting of a vinylidene chloride copolymer containing at least about 50% of vinylidene chloride and an interpolymer comprising a minor amount of acrylic acid, methacrylic acid or mixtures thereof and a major amount of neutral monomer esters comprising methyl acrylate, ethyl acrylate, methyl methacrylate or mixtures thereof. A method for producing the heat sealable multilayer film structure is also provided.
