Logging tools are generally designed for operation under limited borehole conditions. A minimum hole size is the consequence of maximum tool diameter and pad curvatures, while maximum hole size is established by signal strength and caliper arm lengths. Mud types can affect signal transmission. Hole position affects signal strength and mud or borehole effects. Table 1 provides general operating limitations for the standard logging tools. Service companies have specially designed or modified tools that may allow extension of operation ranges. Consult your local representative if hole conditions are not as recommended in Table 1.
