W ell Logging and -Testing Techniques A pp lied to Reservoir Analysis

CIM Bulletin, 1952


THE PURPOSE of this paper is to discuss briefly the main logging and testing devices presently at our disposal, to point out some of their limitations, and to suggest possible improvemen1ts of the techniques. Some of the more important devices .are those that are used in: (1) Coring (2) Formation testing (3) Electric well Jogging ( 4) Radioactive well Jogging ( 5) Measuring of bot tom hole pressures (6) Sampling of reservoir fluids The first four of these procedures are concerned with the well while it is in the process of drilling. The last two are carried out as soon as possible after a well has been brought into production and at intervals during its life. My remarks will be concerned mostly with certain aspects of formation testing. The reservoir engineer is dependent on the information -derived from these operations in order to obtain a clear picture -of the conditions in a reservoir and to enable him to assess and forecast its future behaviour.
