Abstract
An improved downhole pressure measuring apparatus includes a flow tube conveying pressurized fluid from a fluid source on the surface into a borehole. The fluid flow and pressure is measured at the surface and the downhole pressure is determined. A perforating gun firing mechanism may be attached to a lower end of the flow tube and positioned in the borehole respective to a perforating gun for the firing thereof. The gun is fired by manipulating the flow tubing and the downhole pressure is simultaneously recorded.
