.../temperature gauge (PTG) that provides a permanent bottomhole pressure/temperature gauge (PTG) that provides a continuous readout at surface. The gauge was installed primarily to monitor pump intake pressure and to avoid operation when the pressure falls below bubblepoint. Gauge specification and installation...

... be placed at the desired depth to target the best rock for stimulation. Another benefit of CT fracturing is the ability to gather BH treating pressure via BH gauges (BHG) mounted on the CT bottomhole assembly (BHA). Bottomhole pressure and temperature gauges, installed above and below the isolation packer...

... in the choke example. The flowing bottomhole pressure and temperature gauges are similar to the downstream pressure and temperature across the choke. However, it was recognized that the flowing bottomhole gauge is placed ~300 – 500 feet downstream of the completions. This vertical distance causes the following...
