Abstract: An apparatus for obtaining a plurality of fluid samples in a subterranean well includes a carrier, a plurality of sampling chambers and a plurality of pressure sources. The sampling chambers and pressure sources substantially comprises non-metallic materials. One or more of the following: conductors, transducers, power sources, communicators, data memory and processors are embedded in the materials comprising the sampler apparatus. One or more transducers for measuring the temperature, pressure, and volume of the sample are present in at least one of the plurality of sampling chambers. Means for measuring the parameters of the wellbore fluid are also present in the sampler apparatus. Means for communicating measured data to the surface are provided in the sampling apparatus.

Abstract: A logging sensor or tool including a structural component, a non-structural component, and a composite disposed between the structural component and the non-structural component. The composite may contain a metallic foam having pores and an elastomeric material deposited in the pores. The elastomeric material may include an elastomer and a plurality of metallic shield particles. A logging system and to a wireline system containing such a logging sensor or tool.

The elastomeric material may include an elastomer and a plurality of metallic shield particles. The disclosure further relates to a logging system and to a wireline system containing such a logging sensor or tool.

Abstract: There is disclosed a method of making an imprint on a polymer structure comprising the steps of: a) providing an imprinted substrate mold having a defined imprinted surface pattern on a first side and a defined imprinted surface pattern on a second side, opposite to the first side; b) pressing a polymer structure against the first side of the imprinted substrate mold to form an imprint thereon; and c) pressing another polymer structure against the second side of the imprinted substrate mold to form an imprint thereon.
