Abstract: A method and system for obtaining core samples using a coring fluid. During the drilling phase of hydrocarbon wells and the like, drilled with existing drilling systems, the bit that drills the well is driven by a string of rotating pipes and drilling mud is introduced in the rotating pipes. The drilling mud rises carrying with it the cuttings produced by the drill bit. Alternatively to the current operating method, the rotating pipes can be removed and a special piece of equipment called a core barrel is mounted thereon. The rotating pipes thus equipped for collection of the "core" are then lowered into the well. According to the present invention, when the rotating pipes are at the bottom of the hole, a sufficient volume of a colloidal, viscous coring or embedding fluid is introduced into the mud circuit to encapsulate a sample of the cuttings, for lifting to the surface and subsequent analysis. The fluid prevents the cuttings from being altered by the drilling mud.

Abstract: Racking apparatus and method for accomplishing racking of drilling pipes in a vertical position from the rig floor downward.A container located in the substructure area of the floating platform provides for the supporting of the pipes; while a triple-acting racking crane provides for the handling and racking operation of the pipes and, two racking frames provide for proper alignment of each stand inside the container.Auxiliary equipment is also provided for working in connection with the racking apparatus in order to fit all phases throughout the racking operation.
