Time-Lapse VSP Test Results Demonstrate Good Repeatability For Both Land-Vibrator And Marine-Air Gun VSP Surveys In Middle East Carbonates

Abstract: VSP results successfully demonstrate that high resolution VSP data can be collected and are repeatable in the Abu Dhabi carbonate environment. Comparisons between shallow marine air gun and land vibrator VSP images show similar quality results, suggesting that land and marine surveys can potentially be combined in transition areas. Walkaway VSP repeatability tests with a marine air gun and land vibrator show that VSP images can be repeated with significantly lower background noise compared to surface seismic. Background noise is the non-repeatable signal that remains after subtracting two VSP images collected at different times, when no changes in the subsurface have occurred. With fixed geophones and an optimized 4D VSP processing flow background noise levels below 1% of the original VSP amplitudes were achieved. Both reflected p-wave signals and converted shear wave signals were found to be repeatable. The positive results from this VSP repeatability pilot and a 4D feasibility study indicate that time-lapse 3D-VSP’s could provide another means for monitoring reservoir saturation changes in Abu Dhabi Carbonate fields.

Feasibility of Combustion Turbine Inlet Air-Cooling in the Arabian Gulf Region

Abstract: Combustion turbine inlet air-cooling systems (CTIACS) have been implemented in various regions around the globe and have displayed proven results in terms of their effectiveness and economic feasibility. Nonetheless, these systems have been rarely employed in the Arabian Gulf region with such existing installations are still undergoing continuous evaluation. The main objective of this study is to highlight the associated benefits of employing a CTIACS option in UAE. This is achieved by first exploring the weather patterns in UAE in order to propose proper weather design conditions. Moreover, the impact of a CTIACS is presented, for a prescribed inlet air temperature, on the annual gross energy increase, average heat rate reduction, cooling load requirements and net power increase. Finally, a combustion turbine unit with a relatively small mass flow rate is shown to be very much feasible economically even upon reducing inlet air temperature below the ISO rating.Copyright © 2002 by ASME
