摘要： A wellbore (10) in an earth formation (12) having a casing (14) and a plurality of pay or production zones (32, 34, 36) provided in the formation. A coiled tubing string (18) from a reel (20) is injected by an injector (24) into the wellbore (10) for first perforating casing section (38) at each pay zone (32, 34, 36) in a single pass of the coiled tubing (18) as shown in FIG. 1. Next, the coiled tubing (18) is utilized for hydraulic fracturing each of the pay zones (32, 34, 36) individually from the lowermost pay zone (32) to the uppermost pay zone (36) in a single pass of the coiled tubing (18). Each pay zone (32, 34, 36) is isolated for the hydraulic fracturing. An upper packer (44 or 54) is provided above each of the pay zones for isolation and a lower packer (56) or sand plug (50) is utilized for isolating the lower or outermost end of each pay zone (32, 34, 36). Swab cups (58, 54A, 56A, 54B, 56B) are also utilized for isolation of pay zones.

摘要： A technique to place a completion assembly in a well while maintaining the well in an underbalanced condition includes running a plug on a deployment tool to a desired depth in the well. The technique includes setting the plug in the well; retrieving the deployment tool; and running the completion assembly on a setting tool into the well to engage the plug. The technique includes releasing the plug; running the completion assembly and plug to a desired depth in the well; and setting the completion assembly in the well. The setting tool is retrieved, which includes retrieving the plug.
