4.4 Examine the log heading of Fig. 4.49. a. On linear graph paper, plot the maximum recorded tem- peralure vs. depth. b. Is the assumption of linear thermal gradient acceptable in this case? c. Find the mathematical depth/temperature relationship for the subject well. d. Plot a cross section of the well. e. Calculate the mud and mud-filtrate resistivities of the drill- ing fluid sampled for the eight log runs at 75°F. Plot Rmf vs. Rm. Does a strong correlation exist between these two parameters? Can this relation be predicted by any of the methods discussed in this chapter? SCHLUMBERGER WELL SURVEYING CORPORATION STL, TEXIS RUN No. Date First Reading Last Reading Feet Measured Csg. Schlum.
