| dc.description.abstract | World's oil and gas reserves are rapidly diminishing and they don't have to actually run
out before precipitating a crisis. Predictions indicate that the peak and subsequent decline
in world oil production will probably occur within the next few decades and as the
demand tor fossil fuel energy has increased dramatically over the past years, so has the
necessity for more accurate methods of locating these deposits.
This research project the most promising method of application of geophysical well logs
in the search for stratigraphic traps in the Lamu basin, including their use in correlation,
location of facies change or pinch-out, analysis of subsurface resistivity fluids and
determination of formation porosity and permeability.
Electric induction log was utilized which provided the data for evaluation of reservoir
properties. In addition, the information from the log header was applied in the calculation
of resistivity values of fluids. Necessary corrections were made on resistivity fluid values
to formation temperature by the use of charts courtesy of Schlumberger well Services and
Dresser Industries.
Processed lithologic well log data for the selected wells was utilized to generate fence
diagram, which were effective in demonstrating changes in lithologic facies, pinch outs,
unconformity and other stratigraphic conditions OCCUlTingin the basin thereby allowing
inferences to be made on the location of stratigraphic types of traps in the Lamu basin.
Quantitative reservoir parameter evaluation results for the wells were obtained that
indicate moderate to poor porosity | en |
