Abstractperform Vertical Seismic Profiling (VSP) and passive seismic monitoring. However, this technology is very expensive to apply. Drilling a new well or taking a valuable well out of service is costly, as is VSP data acquisition and processing. Consequently, the technology is seldom used, and, hence, it is very difficult to ascertain if the CO2, whether used for oil production or sequestered as a greenhouse gas, remains where it is intended. Therefore, one of the goals of the DOE Microhole program is to produce tools for drilling inexpensive "designer seismic" wells (i.e., placed where needed). This project will prototype and test a version of a patented inverted electric motor in a new system that will enable the drilling of faster, hence less expensive, microbores for the permanent installation of small, inexpensive VSP receivers. Phase I will evaluate: (1) the required modification and mating of the motors with industry available components for a complete "electrified" bottom hole assembly (first step toward a truly Â¿smartÂ¿ drilling system), including the motor mounting, seals, and bearings; (2) compatibility with advanced drilling techniques, including abrasive slurry jetting; (3) power unit and bi-directional signal cabling; (4) control and communications; and (5) coupling with optimal geophone technology, number, size, and placement. Phase II will bench test the components and field test the assembly. Commercial Applications and other Benefits as described by the awardee: In addition to help make CO2 monitoring with VSP less expensive, these motors and the overall assembly should find application in conventional oil and gas drilling (vertical and directional); for boring, digging and trenching in hard rock areas; for utility installation of buried pipes and pipelines; in mining resources; in construction piering; and in environmental well drilling.
