Spacing between transmitter and receiver

Input(s)

soff: s_{\text {off: }} Tool Standoff (in.)

CmfC_{m f}: Mud/Formaton Velocity Contrast (dimensionless)

Output(s)

(Ls)c\left(L_{s}\right)_{c}: Transmitter-to-Receiver Spacing (ft)(\mathrm{ft})

Formula(s)

(Ls)c=2soff(1+Cmf1Cmf)0.5\left(L_{s}\right)_{c}=2 * s_{o f f} *\left(\frac{1+C_{m f}}{1-C_{m f}}\right)^{0.5}
