The Deep Sea Drilling Project (DSDP) and Ocean Drilling Program (ODP) have developed numerous downhole tools and systems that have already found or might soon find applications in oil and gas exploration. Other potential applications for these coring tools, drillstring designs, and bottom hole assemblies (BHAs) include offshore mineral and resource evaluation, offshore geotechnical engineering, environmental monitoring, geothermal energy research hazardous waste disposal/site qualification, and general geoscience research. This new technology is expected eventually to become used by industry and benefit all participants. To date, little of the anticipated technological spin-off has occurred. Both DSDP and ODP have had limited formal technological reporting, and their engineers have not worked under a publish-or-perish mandate. This paper describes the drillship, drilling equipment, stress analysis software, a multipurpose BHA, drill-in casing, reentry system, hard rock guidebase, and a freefall reentry cone.
