Contents Notes
The functions of drilling fluids and of the constituents in them are reviewed in detail. Chemicals used in the drilling fluids and in well completion and treatment are listed; it is seen that several of them are quite capable of polluting water and land. Drilling fluids are usually either water- or oil-base. The compositions of some oilfield brines and crude oils which can be used to prepare drilling fluids, are listed and discussed.^Possible ways in which that drilling fluids and well operations may contaminate ground water are outlined. The effect of the type of the drilling fluid (oil- or water-base) on the contamination is described. Contamination by natural gas well blowouts and unsealed surface pits containing drilling fluids and brines is also considered. Finally, methods for rehabilitating a contaminated aquifer are discussed briefly. 9 figures, 8 tables.
