Abstract
Pressure While Drilling (PWD) data was collected on several wells drilled in Nevada, USA in 2025, and was used to calculate injectivity index in real time and to do injection tests. This provided real time injection capacity estimates while saving rig time. This paper will cover (a) a descrption of the PWD technology, (b) a number of examples where comparison between PWD injectivity calculations versus injection test results after the wells were completed, and (c) a brief discussion on future optimization of the approach.
