<p>A slickline conveyed perforating method and apparatus is adapted to be disposed in an extremly small diameter cased borehole, especially during extreme overbalanced perforating conditions, and the apparatus includes one or more shock absorbed pressure and temperature measurement gauges adapted for measuring the pressure and temperature in the small diameter cased borehole before, during, and after the perforating operation. An 'extremly small diameter' borehole is defined as a borehole which has a diameter that is always less than the diameter of any production tubing which would normally be inserted into the borehole.</p> |
