Oil and gas field chemicals |
| abstract |
This invention relates to a process for increasing the effectiveness of production chemicals by reducing the number of squeezing and shut-in operations needed to increase the production rate from an oil well. The process comprises injecting into an oil-bearing rock formation matrix a water-miscible formulation comprising: (a) a water-miscible surfactant which is an alkyltriglycol ether and (b) at least one water-miscible oil field or gas field production chemical, said (a) and (b) being introduced either as a pre-formed, single, homogeneous composition, or simultaneously in parallel or sequentially in either order into the rock formation characterised in that after introduction of (a) and (b) into the oil-bearing rock formation, the well is shut-in for a period and, subsequently, the oil-bearing rock formation matrix is over-flushed with an oil. |
