Abstract: A sample module is provided for use in a downhole tool to obtain fluid from a subsurface formation penetrated by a wellbore. The sample module includes a sample chamber carried by the module for collecting a sample of formation fluid obtained from the formation via the downhole tool, and a validation chamber carried by the module for collecting a substantially smaller sample of formation fluid than the sample chamber. The validation chamber is removable from the sample module at the surface without disturbing the sample chamber. A sample chamber is also provided that includes a substantially cylindrical body capable of safely withstanding heating at the surface, following collection of a formation fluid sample via the downhole tool and withdrawal of the sample chamber from the wellbore, to temperatures necessary to promote recombination of the sample components within the chambers. Additionally, the body is equipped so as to be certified for transportation.

Abstract: A cable for data transmission comprising a core comprising at least one energy transmission line; a jacket enclosing the core; armor strands wound around the jacket; and an embedding elastic structure, surrounding the jacket and designed to receive the armor strands. The cable may be manufactured as follows: (1) surrounding the core with a jacket; (2) surrounding the jacket with an embedding layer of curable but non cured thermosetting material; (3) enclosing the thermosetting layer with helically wound armor strands, in such a way that complementary grooves are generated in the embedding layer; and (4) subjecting the cable to heat in order to cure the thermosetting material of the embedding structure.
