Extensive testing of through-the-flowline (TFL) tools in 2 land wells equipped as diverless subsea well completions has given Standard Oil Co. of California valuable experience for developing: (1) gas-lift capability for deep water seafloor completions; (2) reliable TFL methods for routine maintenance such as safety valve installation, sand cleanout, and paraffin removal; and (3) specialized hydraulic jet pumping methods for nonflowing oil wells. All of these techniques and more were evaluated in carefully simulated sea-floor configurations using, primarily, Otis Engineering Corp. TFL tools and Kobe, Inc., prototype jet pumps. Complete sea-floor artifical lift capability was not achieved in this research type project. However, a state-of-the-art was established and areas for further development were defined. Pump down fluid rates of 0.5 to 2.0 bpm were used for most operations. Surges of up to 2.5 bpm were used occasionally to free stuck tools. Rates as low as 0.1 bpm allowesippi. This distribution is related to the draping of the Wilcox sequence over ntary for dried tuff stone impregnated with 23.6arilyifer or existence, ahead of the hydorfluoric acid front, of a ures which might control the distribution of uraniumacterized by a thermally activated process. he effect of various parameters, temperature, pressure, and steam percent in hydrogen feed. Fifteen experimental runs have been completed using NiMo as the main component of thThe Q/sub 2//sup +/ value obtained for /sup 200/Hg is in agreement with previous work, but that for /sup 202/Hg is not. The results obtained are compared with the predictions of various nuclear models, and the mass dependence of Q/sub 2//sup +/ in the region 182 < A < 206 is examined.
