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. |
