Formation pressure while drilling for slimhole applications

Drawing on the experience of the larger formation pressure-while-drilling (FPWD) services, the StethoScope 475 multifunction FPWD service makes accurate measurements—in smaller hole sizes. With a maximum OD of 5 3/4 in, the FPWD tool provides direct pore pressure and mobility data for fluid typing, reservoir pressure management, and mud-weight control and optimization.
