Density and compressional velocity logs were utilized in generating the overburden pressure, shale trend and Normal compaction Trend which are used for the pore pressure prediction. The petrophysical data were evaluated using Ikons Science Rokdoc software. This study appraised ten industry utilized pore pressure prediction models with the view of ascertaining their accuracy using offset well data in the form of wireline logs and Repeat Formation Test data. When these abnormal pressures are not predicted accurately prior to drilling, disastrous occurrences, such as formation fluid kicks, well blowouts and loss of drilling mud may take place. They are mostly abnormal pressures, predominantly in the form of overpressured zones. Different plays and situations will require modifications to this workflow and additional RokDoc tools.A thesis presented to the Department of Petroleum Engineering, University Of Benin In partial fulfilment of the requirements For the degree of MASTER OF ENGINEERING By Abubakar Tanko Supervised by Dr Bello Kelani ABSTRACT The pore pressures in most sedimentary basins including the Niger Delta are rarely normal. It is designed to highlight some of RokDoc’s extensive functionality, rather than an exhaustive list. RokDoc OverviewThe below shows a snapshot of RokDoc’s capabilities in a generic workflow. Define polygons to identify different AVO classes and facies in seismic data, or utilise the weighted stack cross-plotter to rotate and manipulate pairs of inversion volumes to reveal hidden lithology and fluid information. The RokDoc 3D cross-plot allow users to integrate well, seismic and rock physics data and establish whether inversion results are consistent with forward models from well data. RokDoc makes it simple to perform all the usual fluid substitutions, variable contacts and pressure perturbations, etc.The addition of the RokDoc Reservoir Characterisation modules to your tool kit, brings a range of sophisticated tools convert existing inversion volumes into meaningful and accurate geological rock properties for prospect evaluation. Using the Rock Physics modules a 'basic' RokDoc user will easily make geological ‘sketches’ of a seismic interpretation and then determine if the synthetic matches the seismic. The tools can be used to identify porosity and many other types of geological variations, based on seismic and well data.
RokDoc has unparalleled rock physics modelling capabilities and Rock Physics Model Templates. Use it to analyse well and seismic data, determine value and apply quantitative methods to predict rock, fluid and pressure properties.With RokDoc seismic data can be integrated with log data and pressure data. Rokdoc 6.4.2RokDocRokDoc has been developed in collaboration with major oil companies and academic experts since 2001.
