英文摘要	In this Phase 2 SBIR program, Vista Clara successfully developed and field-tested small diameter NNR logging tools for subsurface characterization and monitoring. This effort involved the design and development surface electronics, a winch with 470ft cable, and three interchangeable downhole probes: a 3.5Ă˘ diameter borehole NMR probe, a 1.67Ă˘ diameter borehole NMR probe, and a 2.5Ă˘ diameter NMR probe that can be deployed using a Geoprobe direct push machine. The 3.5Ă˘ probe was tested extensively over a 6 week period including 4Ă˘ to 8Ă˘ boreholes in Washington, Idaho, Nebraska, Colorado, Kansas, Connecticut and Massachusetts. The field test campaign was highly successful. The 1.67Ă˘ probe was assembled, tested and calibrated in the laboratory. The 2.5Ă˘ Geoprobe probe is in final assembly and testing at the time of this report. The completed Phase 2 R&D program has resulted in the first NMR logging tool that can be deployed in boreholes of 4Ă˘ diameter, the first NMR logging tool that can be deployed in boreholes on 2Ă˘ diameter, and the first NMR logging tool that can be deployed by a direct push machine. These small diameter tools make NMR logging technically and economically feasible, for the first time. Previously available NMR logging tools were developed for oilfield applications and are prohibitively large and expensive for the majority of near surface groundwater characterization problems.
