The use of computers in well logging has advanced from a research to an operational stage. Well-site computers may be either part of standard surface equipment, allowing direct reading of some formation parameters (density-porosity) or they are additional equipment permitting on-site merging of data from several logs. Digital computers in the office are used for the complete interpretation of all zones logged. Examples were given using logs from Nigeria. Eventually all well logs can be recorded on magnetic tape. Recording and processing of dipmeter logs on tapes currently are available in Libya.
