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.

Seismically Derived Porosity Prediction for Field Development- An Onshore Abu Dhabi Jurassic Carbonate Reservoir Case Study

Conference (other), November, 2016

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.

A Geological Characterization of Carboniferous and Jurassic Shale Gas and Shale Oil Plays of the United Kingdom.

Workshop/forum/seminar (other), November, 2016
©2016

Results of the evaluation of Jurassic Shale Oil Plays in the Wessex Basin and the Carboniferous Shale Gas Play in the Bowland Basin are summarized in this paper. A common risk segment based approach was used, integrating geological and geochemical data with petrophysical data to understand and map the controls on prospectivity of these shale plays and identifying “sweet spots” for more detailed assessment.

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.
