The repeat formation tester (RFT) tool was designed to measure formation pressure quickly and accurately. It measures pressure at specific points on the borehole wall. The diagram below shows a typical RFT tool. Formation pressure is measured by the formation sampler (see diagram in [[:file:formation-fluid-pressure-and-its-application_fig5-16.png|Figure 1]]) when it is extended from the tool to contact the formation. Fluid samples from the formation can also be taken with the tool.
