Abstract:
A formation fluid evaluation system (100) interconnected within a tubular string (118) for operation in a wellbore (102) having multiple zones (106, 108, 110). The evaluation system (100) includes a pair of straddle packers (120, 122) that isolates one zone (108) of the multiple zones (106, 108, 110), a test valve (124) disposed between the straddle packers (120, 122) and an upper packer (126) positioned uphole of the uppermost zone (106) of the multiple zones (106, 108, 110). A fluid lift assembly (128) is position uphole of the upper packer (126). The fluid lift assembly (128) is operable to draw fluid (134) from the isolated zone (108) into the tubular string (118) through the test valve (124). A formation evaluation instrument (136) is disposed within the tubular string (118) and determines a characteristic of the fluid (134) received from the isolated zone (108).
Abstract:
A method of stimulating a production interval adjacent a well bore having a casing disposed therein, that comprises introducing a carrier fluid comprising first particulates into the well bore, packing the first particulates into a plurality of perforations in the casing, perforating at least one remedial perforation in the casing adjacent to the production interval, and stimulating the production interval through the at least one remedial perforation. Also provided are methods of stimulating multiple production intervals adjacent a well bore.
