Abstract

In general, the pressure is directly proportional to the depth caused by the continual pressured stress of rock. From resistivity log data, a monograph indicating the relationship between increasable resistivity and depth can be created. In this study, resistivity log data of Mae-Soon oil field had been estimated its trend by applying Microsoft Office Excel 2003. This trend could be used for pressure gradient estimation by using an invented resistivity related pressure monograph. As a result, a monograph for pressure gradient estimation for Mae-Soon oil field, located in Fang basin, was created. Result from created the pressure estimation monograph testing indicated that the erroneous percentage of pressure estimation of Mae-Soon oil field was (+4.47333) to (-4.28667).Moreover, pressure gradient estimation of Mae-Soon oil field by using the created monograph was quite accurate with very low erroneous percentage as (+0.00082) to (-0.00068).
