Abstract
In this work four acidizing treatment systems have been formulated to treat various degrees of wellbore damages due to organic and inorganic materials, fines, mud-cake and other particles that block perforations and pore spaces around the wellbore. The treatment fluids are: clay stabilisation system, matrix stimulation system, non retarded mud acid system and oil-based dispersant fluid system. Emulsion break tests were conducted at test temperatures of 80°F, 150°F and 190°F. Clay stabilisation and matrix stimulation systems separated out of solution within the acceptable time of 10 minutes at all the test temperatures and showed no incompatibility. The rest of the treatment fluid systems separated after ten minutes. It was observed that, the higher the temperature, the faster the separation in most of the tests. It can be concluded that, different formation fluids react and behave differently with matrix acidizing treatment fluids and thus every treatment fluid would have to be tested for compatibility with formation fluid to ensure a successful stimulation.
