Evaluation of a Novel Downhole Fluid Analysis Tool

Purchage Technologies Ltd.开发了一种用于水平钻井作业的新型井下油气工具。它结合了水平井生产、压力瞬变分析和连续油管钻柱测试的特点。该工具使用跨座式封隔器进行分层隔离，以分析油、水和天然气的生产情况，并进行储层描述。该公司与SAIT接洽，以开发一种说明干扰化学品和添加剂的操作程序，并评估其正在申请专利的核磁共振(核磁共振)传感器，该传感器被纳入他们的多级评估工具(MSET)。利用核磁共振传感器，MSET可以被放置在井下以隔离油井的部分，以提高产量，同时减少产出油的水和矿化度污染。

Pursuit Technologies Ltd. developed a novel downhole oil and gas tool for use in horizontal drilling operations. It combines the features of horizontal production, pressure transient analysis and coiled tubing drill stem testing. The tool uses straddle packers for zonal isolation to analyze oil, water and gas production and for reservoir characterization. The company approached SAIT to develop an operational procedure that accounts for interfering chemicals and additives and evaluate their patent-pending Nuclear Magnetic Resonance (NMR) sensor that is incorporated into their Multi-Stage Evaluation Tool (MSET). Using a NMR sensor, the MSET can be placed downhole to isolate sections of the well to increase production while reducing water and salinity contamination of the produced oil.
