SUCCESSFUL FIELD IMPLEMENTATION OF A BULL HEAD WATER REDUCTION SYSTEM
For many years, bull head systems to reduce water production have received a great deal of attention from the oil- and gas-production industry. Previous papers have discussed the laboratory development of a new bullhead system based on a hydrophobically modified polymer. This paper will outline the field implementation of this system and will describe some of the successes (and failures) of the system. Even though bull head systems do not seal off water zones and thus do not have the capability to completely stop water production, it will be demonstrated that these treatments can be extremely economically attractive. While field
