ABSTRACT:
In the representative embodiments of the new and improved apparatus disclosed herein, a string of full-bore well tools are arranged to be suspended from a pipe string in a well bore penetrating an earth formation in flow communication with the well bore. A full-bore packer coupled to the pipe string is operated from the surface for isolating the well bore interval below the packer from the fluids in the well bore thereabove. To test the formation, a test valve coupled to the pipe string is selectively operated from the surface for opening the pipe string to the flow of formation fluids from the isolated well bore interval. Thereafter, when it is desired to obtain a sample of the formation fluids flowing in the pipe string, the new and improved full-bore sample-collecting apparatus coupled to the pipe string is selectively operated from the surface to admit the fluids in the pipe string into an annular sample chamber within the new and improved apparatus. The sample collecting apparatus is further operable only in response to the admission of formation fluids into the sample chamber to regulate the flow rate at which these fluids are admitted into the sample chamber so as to not disturb the fluid sample any more than is necessary. Thereafter, this apparatus operates only in response to filling of the sample chamber for trapping the fluid sample.
