Wireline log shapes through barrier island sequences vary depending on exactly where a well intersects the barrier island complex. [[Basic open hole tools#Gamma ray|Gamma ray]], [[Basic open hole tools#Spontaneous potential|SP]], and [[Basic open hole tools#Resistivity|resistivity]] logs through the barrier core have an upward-coarsening motif (Figure 3f). Logs through the back barrier and lower shoreface are typically highly serrate and often lack a well-defined upward-coarsening motif. Logs through the barrier inlet may exhibit upward fining. | Wireline log shapes through barrier island sequences vary depending on exactly where a well intersects the barrier island complex.
