Abstract: Expansion joint system of a concrete slab arrangement, comprising an expan-sion joint reinforcement to be arranged between a first and a second concrete slab (1, 2), the expansion joint reinforcement comprising at least two local dowels (3)transferring loads perpendicular to the slab plane. The dowels com- prise a dowel plate (4) and a casing part (5). The dowel plate (4) and the cas- ing part (5) are attached to the concrete slabs on different sides of the joint. The casing part (5) prevents the dowel plate from adhering to the concrete slab and allows the dowel plate (4) to move inside the casing part and thus allows the movements of the slabs (1, 2) in the horizontal direction. The dowels (3) are installed alternately relative to the joint sothat the casing parts (5) of the adjacent dowels (3) are always installed on different sides of the joint.

IPC: E21B47/00
Filed: 2009-10-01
Abstract: A method of characterizing formation fluid present in a subsurface earth formation during drilling using methods for correcting the measured concentrations of gas components in drilling mud. Gas trap values for the gas components of interest, light hydrocarbons, are measured during mud logging and are corrected using relative response factors, determined from laboratory fluid analysis values and relative extraction efficiency values. The relative response factors for each gas component of interest can be used for correcting additional gas trap values measured in the same well or for correcting gas trap values measured in surrounding wells utilizing a similar drilling fluid. The corrected gas trap values for each of the gas components of interest can be utilized to calculate gas/oil ratios for characterizing the formation fluid from the volume of drilling mud.
