... while drilling (FPWD) was evaluated and used in Well A of W block. To moderate the influence of supercharging and obtain the best quality formation pressure, pumps-off pretest has been tried for first time in the south China sea which can take pretest while mud circulation stops and a battery provides...

... behavior versus time in a pretest, one can a direct measurement of fluid mobility. This mobility can be converted to permeability if fluid viscosity is known. We can then use the permeability derived from pretests to calibrate the specific surface area of clay in our permeability log interpretation. Here...

... rise to fluid complexities include current/multiple reservoir charging, biodegradation, water/gas washes, and leaky seals. Asphaltenes gradient can also be used to complement pressure for vertical compartmentalization and lateral continuity analysis. Efficient probe pretesting tool with capability...
