The basement rocks are unconformably overlain by a range of thin (5–35 m thick) carbonate-cemented sandstones of different ages: Jurassic Rona Sst in 205/21-1A, Lower Cretaceous Victory Formation in 205/21a-7 and Upper Cretaceous Commodore Formation in 205/21a-4Z. In all cases, these local cover sequences are in turn overlain by thick ...

basement in Yemen is exposed as N–SorNE–SW, 10– 30 km-wide parallel belts, which are composed of high- grade gneisses, amphibolites, and migmatites alternating

Basement rocks are among the most significant unconventional oil and gas reservoirs. Fractured or weathered granites are examples of such reservoirs found globally. Fractured basement reservoirs represent favourable targets for hydrocarbon exploration in the Gulf of Suez Basin. ... In West Yemen, deep wells at depths of up to 3383 m yield ...

The Sab'atayn Basin is one of the most prolific Mesozoic hydrocarbon basins located in central Yemen. It has many oil producing fields including the Habban Field with oil occurrences in fractured basement rocks. A comprehensive seismic analysis of fractured basement reservoirs was performed to ident …

This case study of ten oil wells drilled into highly fractured and heterogeneous crystalline basement rocks of the Bayoot Field, Say'un Masila Basin, Yemen, brings together the findings from a wealth of oil field data and shows that a multidisciplinary approach is required for full characterization.

The basement rocks of Yemen is considered a part of the Arabian shield which can be divided into five terranes. Asir terrane, Abbas terrane, Al Bayda terrane, Al Mahfid terrane and Al Mukalla terrane.They arrange in manner that reflect the …

Fig. 5: Regional structures in the southeastern sector of the basement rocks of Yemen. mapped area. This belt is affected by a complex pattern of major structures that represent the interference of more than one phase of deformation. The most prominent are two huge regional overturned folds (Fig. 5) that plunge to the NE (Abdel Wahed, 2000).

The Precambrain basement metamorphic and igneous rocks of Yemen represent the southeastern part of the Arabian–Nubian shield. Early reconnaissance works on the …

For example, the Arabian shield basement of Yemen and the Tertiary basement granites offshore Vietnam are two classic areas for this type of development, and significant …

In their geochronological study of Yemen basement rocks, Whitehouse et al. (1998) proposed tentative correlations with Precambrian basement rocks of Saudi Arabia and Somalia. The aim of the present paper is to review the main tectonic units and isotopic characteristics (existing geochronological and Nd-isotope data; new Pb- and Nd-isotope data ...

Basement rocks in Yemen cover around ( 105.000km2) area and exposed in the northwestern and southeastern parts of the country ( Whitehouse et al. 1993Whitehouse et al., ...

In Southeast Asia, basement reservoirs are the main contributor of oil production in Vietnam. In Indonesia, to date oil and gas production from basement rocks has been minimal. However, the recent large gas discovery in pre-Tertiary fractured granites in southern Sumatra has led to a focusing of exploration in Indonesia for basement reservoirs.

The Basement rocks of Yemen represent the southern extension of the Arabian Shield Fig(2), is of Paleoproterozoic to Neoproterozoic age. In Yemen has identified five terranes, which can …

To display and extract significant relationships between rock-types and log responses, and to control the output of the neural-network, cross-plots have been used. The most sensitive logs for rock matrix variations for all crystalline rocks within the Habban-Basement are the RHOB bulk density log and the GR log
