Experience and Research Interest

My research concentrates on the following major topics:

1. From Ocean Floor to Continent: Mineralogical and geochemical alteration of geologic bodies over time on the example of marine metal deposits (in particular: massive sulfides and manganese oxides).
2. Environmentally friendly remediation of mining/industry wastes contaminated by heavy metals and cyanides (from gold extraction) through biomineralisation and biodegradation to reduce environmental toxicity.
3. Optimised bioleaching and enrichment of heavy metals and gold from mine wastes. Co-operation with the (mining) industry and other scientific institutions is an integral part of the research work. Currently, ore and rock microscopy, SEM and geochemical microanalysis (EDS), XRD, Photometer, AAS, thermodynamic modelling, and GIS are the main research tools.

Teaching Interest

Apart from examining metamorphic processes, I am very much interested in conveying concepts on how biology (especially microbial life) interacts with the formation, alteration, and remobilization of minerals & rocks (mineralogically, (bio-)geochemically). In order to do this in a learning environment, the students need to be shown how to adopt a multi-disciplinary approach. This is best achieved via a “Walk - See - Touch - Absorb” strategy in different fields, which assists the students to grasp difficult concepts more easily and strengthens their skills, rather than only confronting them with theories (which are also necessary occasionally).

Experience and Research Interest

1. Tectonics & Sedimentation: The late Cretaceous siliciclastic sequence of the Qahlah Formation was deposited during orogenic uplift of the Oman Mountains. Detail study of such sequences deposited in peripheral basins in close proximity of orogenic belts record uplift history, paleodrainage system and climatic changes associated with uplift of the major mountain systems. Presently I am working on sediments of the Qahlah Formation along various sections in the Oman Mountain belt to establish relationship between tectonics and sedimentation during the late Cretaceous time.
2. Sedimentology of Permian fluvial rocks: The fluvial rocks of the Gharif Formation of early-middle Permian age are widely distributed and host major hydrocarbon reservoirs in central Oman Interior basin. At places these rocks are nicely exposed in the basin and are focus of sedimentological, depositional and provenance studies. I am presently studying the formation in central Huqf area where its upper member is nicely exposed and will use these studies as a surface analogue for the subsurface studies.

Teaching Interest

I teach courses in sedimentology, stratigraphy and basin studies.

Experience and Research Interest

My research involves qualitative and quantitative analysis of groundwater resources in the arid regions. My main interest is to study groundwater recharge and discharge in the arid regions. This is of particular importance to regions such as Oman where resources are limited and vulnerable to pollution. Over the past five years, my research has focused on developing a better understanding of recharge/discharge fluxes in arid zones with the aim of assessing and monitoring potential threats to groundwater resources in these regions. The core objective of my work is to develop a solid platform for hydrogeological and environmental geology research and training of an international standard at SQU. My research bridges several areas of physical and chemical hydrogeology in arid areas.

Experience and Research Interest

3D and 4D seismic reflection data processing and interpretation for reservoir characterization and time lapse (4D) monitoring for Carbon Dioxide, CO2, sequestration and/or enhanced oil recovery (EOR) and reservoir characterization purposes.  I have interest and developed expertise in the area multi-variate analysis of seismic attributes, fluid replacement modeling, Factor Analysis, Neural Networks based property prediction, and multi-resolution analysis.  I developed synergistic workflows integrating various geo-data for optimized reservoir management and/or prospect evaluation, risk analysis, and validated seismic interpretation. I have utilized advanced techniques in time-frequency analysis in the wavelet transform domain for seismological signal de-noising and enhancement, and multi-resolution analysis. I have developed time lapse seismic reservoir anomaly enhancement technique "parallel progressive blanking, PBB", which was proven to be effective in case of development EOR time lapse seismic for carbonate reservoir, where time lapse anomalies are usually weak and possibly close to the noise background.

A secondary research interest, which is developing of importance to me, is rock physics modeling and its utilization in time lapse seismic feasibility studies, especially those with support from P-waves and S-waves velocity laboratory measurements at near in situ confining and pore-pressures.

Experience and Research Interest

Currently, my research is focused on two main areas, hydrochemical characterization of groundwater system and environmental impact assessment. In hydrochemistry, different techniques such as major chemistry, stable isotopes, strontium isotopic ratios and carbon dating are employed to assess the flow and chemistry of groundwater in semiarid to arid regions as well as estimating groundwater recharge for potential management of the water resources in these areas and their sustainability. The work in environmental geology is carried out to assess the environmental impact of landuse changes on the soil and groundwater resources in Oman.
