Pressure Temperature Log:

After a well is drilled to a desired depth a tool is lowered into the hole that measures temperature and pressure (and often flow) at depth. This information is plotted onto a log and allows production specialists or reservoir engineers to estimate the capacity of a well given the temperature and pressure profile.
