Froya High: An integrated reservoir study of the Late Jurassic sands

PETEX / PESGB - Petroleum Exploration Society of Great Britain, November, 2016
©2016

Recent discoveries in the Pil and Bue prospects, targeting Melke and Rogn Formation sandstones on the footwall of the Vingleia Fault complex, have rejuvenated interest in exploration around the Frøya High region. The wildcat well, 6406/12-3 S (Pil 1), with estimated resources of 8.8-21.1 MMSCM, has focused current attention on combined structural-stratigraphic traps associated with proximal rift sedimentation, restricted to the eastern margins of the Southwest Basin, Halten Terrace. This study provides an integrated reservoir quality assessment of the Late Jurassic Viking Group in the Frøya High region, focusing on sand distribution and reservoir quality.

Porosity estimation using EMERGE for an onshore Abu Dhabi field. CGG processed the seismic and it was followed by seismic inversion. The P-impedance was further used in predicting the porosity. This porosity result very helpful to client to well planning and drilling to target the best porosity in the reservoir. Porosity result matched very well with the new well's acquired porosity data.

The Amplitude Versus Azimuthal AVAZ analysis has proved to be an important tool for characterizing fracture distributions and orientations of hydrocarbon reservoirs. This paper is aiming at the application of this tool for characterizing the fractures in Bahrain field reservoirs. Better understanding of faults and fractures distribution is essential to optimize EOR strategy and reservoir management. Regional analysis is possible by looking at faults distribution characterized by structural attributes analysis validated by regional stress and geological information. The investigation at local scale is more cumbersome but an Amplitude Variation with Azimuth (AVAz) method based on azimuthal Fourier Coefficients (FCs) proves to be a simple and powerful tool to characterize fractures distribution validated by FMI data. The anisotropy information was then used to update and improve the reservoir model long production history matching.

A quantitative interpretation was carried out in order to improve geological model and de-risk the prospect in the next exploration drilling campaign. Recently drilled exploration wells based on conventional seismic interpretation drilled through channel levee instead of the targeted channel core. Vertical resolution, reservoir quality, distribution and continuity of the channel feature are the main risks. A geostatistical inversion guided by rock physics modeling and deterministic inversion has been conducted to improve resolution, analyze the rock character and deliver probabilistic reservoir properties analysis as part of risk assessment. The results show that this technique improves the mapping of channel features associated with porosity and volume of clay distribution in comparison to the deterministic inversion or conventional seismic interpretation.
