Leak-Off Test Analyzer
iOS iPhone Productivity
This app provides for Technicians, Drillers, Toolpushers, Drilling Engineers, Students and others professionals of the oil industry a very helpfull tool to analysis and use during the performing of the leak-off test in wellsite.
About the Leak-off Test on drilling operations:
A test to determine the strength or fracture pressure of the open formation, usually conducted immediately after drilling below a new casing shoe.
Initially, pumping fluid into the borehole results in volumetric compression of the drilling mud column and elastic expansion of the casing string plus rock around the borehole. As the pressure in the borehole increases, the leak-off pressure (LOP) is reached when the relationship between pressure increase and volume of fluid pumped deviates from linear. This occurs when fluid begins to diffuse into the formation at a more rapid rate as the rock begins to dilate. Generally, a LOT is a test that finishes immediately after LOP is reached.
