INJECTION OF OIL SPILL CHEMICALS INTO A BLOWING WELL
ABSTRACT As part of the research program Dispersion of Oil on Sea (DOOS), a subproject has been carried out to develop an all-weather method for oil spill cleanup. The aim of the subproject was to evaluate the possibility of injecting oil spill chemicals into a blowing well. Different completion systems were studied as well as different methods for injection of chemicals. The idea behind the method is to improve the oil spill situation by reducing the response time as well as by providing a method usable in all weather conditions. The method will be of special value for wells located near the coast or in other sensitive areas (e.g., arctic regions). The work concludes that it is possible, and with only a limited need for development of new equipment, to inject chemicals into a blowing well. The injection should be done in the annulus, or through a separate tube. From the annulus the chemical will be inserted into the tubing through a valve.
