Abstract: A method and equipment are described for performing measurements while drilling for oil or gas, in particular VSP-measurements employing a seismic source together with sensors such as hydrophones and/or geophones connected to a memory- and calculation device for storing and processing the seismic signals. The seismic source (2) is placed at or in the vicinity of the surface of the earth whereby signals generated by the source are detected by the hydrophones (3,5) or the geophones located in the vicinity of the source (2) at the surface and in the drill string (4). The geophones or the hydrophones (5) in the drill string transmit the detected signals to a memory- and calculation unit (6) in the drill string that processes and transmits the signals completely or partly to a central data processing unit (10) on the rig (7). The hydrophones or the geophones (3) at the surface simultaneously transmit the detected signals to the central data processing unit at the surface, while chronometers (8,9) showing identical times, connected to the source and to the memory- and calculation device in the drill string make possible a precise calculation of the travel time of the seismic signal between the source (2) and the geophones or the hydrophones in the drill string.

Title: Method for the production of an insulator
Inventor: JUELKE ELIAS
IPC: H01C7/12
Filed: 1996-01-10
Abstract: This method is based on an insulator having at least one component coated with electrically insulating material, in which a primer solution is applied onto the at least one component, in which the applied primer solution is dried to form a primer coat (12), after which the electrically insulating material is applied onto the primer coat (12).      The intention is to provide a method for the production of an insulator having electrically insulating material applied on a primer coat, in which the uniformity of the applied primer coat can be checked in a comparatively simple manner. This is achieved by carrying out the following procedural steps before application of the electrically insulating material: a) dissolving a fluorescent material in the primer solution, b) exposing the primer coat (12) using a light source, c) detecting the points on the surface of the at least one component that are defectively covered with the primer coat (12), and d) if appropriate, applying primer solution onto the points on the surface of the at least one component that are detected as being defectively covered.
