Wireline Logging
Electric logs represent a 1najor source of data to geoscientists and engineers investigating subsurface rock fonnations. Logging tools are used to look for reservoir quality rock, hydrocarbons and source rocks in exploration wells, support volumetric estimates and geological modeling during field appraisal and development and provide a 1neans of monitoring the distribution of remaining hydrocarbons during production life time.
A large investment is made by oil and gas companies in acquiring open hole log data, logging activities can represent between 5% and 15% of total well costs. It is important therefore to ensure that the cost of acquisition can be justified by the value of information generated and that thereafter the information is effectively managed.
