Well Profiles and Terminology A simple build/hold/drop well profile, known as an "S" well, is shown in Figure 2-1. The kickoff point (KOP) is the beginning of the build section. A build section is frequently designed at a constant buildup rate (BUR) until the desired hole angle or end- of-build (EOB) target location is achieved. BUR is normally expressed in terms of degrees per hundred feet (°/100 ft), which is simply the measured change in angle divided by the measured depth (MD) drilled.
