LOGGING WHILE DRILLING KEEPS HORIZONTAL WELL ON SMALL TARGET

Jack Leake Oxy U.S.A. Inc. Houston Frank Shray Schlumberger Well Services Houston The logging-while-drilling (LWD) measurement of two resistivities of different characteristics has led to a new interpretation method for the analysis of horizontal wells. By logging deep and shallow resistivity in real-time, marker beds were identified to help maintain well bore trajectory. The resistivity measurements were split into vertical and horizontal components to provide additional information for
