Abstract

At present there are many techniques being used in processing data acquired from sea bed logging (SBL) applications. Some of the techniques are Finite Element Method (FEM), Finite Difference Method (FDM), Method of Moment (MOM), and Boundary Element Method (BEM). These techniques involve complicated mathematical modeling that requires high computer specification and performance to apply them. Thus, cubic spline interpolation technique and normalized mean square error (NMSE) are proposed as new tools to process these data. Cubic spline interpolation is using differential equations of order 3 and it has the ability to fit SBL data well and NMSE are calculated between original and interpolated data. These NMSE are used to distinguish data that have hydrocarbon (HC) to data that has no HC because data with HC is known to have higher NMSE than data without HC. This was proven from data collected from scaled tank experiments on which HC positions, transmitted frequency and amplitude and spline step size were varied and NMSE were calculated for set up with and without HC. Maximum percentage increased on NMSE obtained from environment with hydrocarbon to without hydrocarbon when oil positions were varied, was 1300%, transmitted EM waves were varied, was 693% at 23.2 Vp-p, frequencies were varied was 1000% and step sizes were varied, was 94%. These high percentage increased in NMSE obtained are able to distinguish data with and with hydrocarbon.
