Jurisdictions covering many square miles, such a...
متن کاملAn Improved Differential Strain Analysis Method for Super Deep Wells
The deeper a reservoir is, the smaller diameter the drilled full diameter cores have. It is difficult to conduct insitu stress experiments with conventional methods if the diameter of the full diameter cores is less than 6.0 cm, especially for cores abundant in natural fractures. In this paper, based on conventional Differential Strain Analysis (DSA) methods and wave velocity anisotropy methods...
متن کاملAn Effective Well Development Method for Deep Screen Completed Wells
In Lund, Sweden productivity problems were encountered during flow testing of a 1927 m deep gravel packed screen completed well and it became apparent that well development was needed to increase productivity. A hydrojetting system using coiled tubing in combination with simultaneous pumping was developed and tested and found to be successful. To verify whether the well development improved the...
متن کاملAssessing marine debris in deep seafloor habitats off California.
Marine debris is a global concern that pollutes the world's oceans, including deep benthic habitats where little is known about the extent of the problem. We provide the first quantitative assessment of debris on the seafloor (20-365 m depth) in submarine canyons and the continental shelf off California, using the Delta submersible. Fishing activities were the most common contributors of debris...
