Hydrogeological Characterization of Maradi Fault Zone in Oman
More LessMaradi Fault Zone (MFZ) is a major structural feature of north and central Oman. With the increase in the petroleum and hydrogeological exploration and production in the PDO concession area especially in the areas with proximitiy to MFZ, concerns were raised regarding the potential of the fault to act as a preferential source of fluid recharge in the aquifers and formations cut by the fault or to act as a seal to fluid flow.

Super-Virtual Interferometric Stacking: Enhancing the Refracted Energy
Authors Ali A. Aldawood, Abdulrahman Alshuhail and Sherif HanafyBuilding an accurate near-surface velocity model is an essential step for many applications in seismic data processing such as wave-equation redatuming, statics correction, and tomographic inversion. Achieving an accurate model requires precise first-break picking of refracted energy.

Imaging a Hydrocarbon Field in SE Albania Using Seismic Interferometry and Passive Seismic Tomography
Authors Sanjay Rana, Nick Martakis, Paris Paraskevopoulos and G-Akis TselentisIn the last decade Passive Seismic Tomography (PST) methodologies have started to be applied in hydrocarbon exploration with an increasing resolution and providing solutions where conventional seismic were either unsuccessful (seismic penetration problems) or un-economical (difficult topography, large areas of exploration, field conditions.

Imaging Structural Geology with Dip and Directional Dip
Authors Ahmed A. Aqrawi and Trond Hellem BoeWe present an improved method of dip estimation as a seismic attribute, and visualize this in 2 components; dip and directional dip. This method proves to be very efficient in highlighting geologic structures.

Multi-Measurement Interpretation — A New Methodology for Basin Mapping and Prospect Identification
Authors Frank Jreij, Marianne Rauch-Davies and Craig BeasleyA wide variety of data sources (publicly accessible, available for license, and newly acquired) and measurements (seismic, electro-magnetic, gravity, magnetic, radiometric, hyperspectral, petrophysical, etc.) are being utilized to develop 3-D subsurface Earth models.

Geological Evaluation and Petroleum Prospectivity of the Jeffara Basin in Southern Tunisia
More LessOutcrop data as well as petrographical studies, tectono-stratigraphic overview and sedimentological investigation were used to construct the depositional environments of Lower Cretaceous series. The rock units, including several third-order sequences were deposited in a variety of inner platform environments with distinct fauna associations in relation with tectonic events and sea level change.

Price Projection Model for New Explorations and the Lost Control of Majors
Oil price prediction is one of the vital processes in every oil producing and operating company for current running projects and future new explorations, the whole different segments of industries and commodities would be also interested in knowing the future of oil prices, and we shall not ignore the interest that each country by itself shows to know the effect of future prices on their development plans.

Neogene Biostratigraphy and Sea Level Changes — Case Study from North Kuwait Field
The Neogene clastics (sandstones and shale interventions) in one of the north Kuwait fields range in age from Early Miocene (Burdigalian) to Middle Miocene (Serravalian). An attempt was made to carry out detailed biostratigraphy (foraminifera, nannoplankton, palynomorphs and dinoflagellate cysts) from study of selected core samples in this geological succession and establish the sea level changes and depositional environment leading to sequence stratigraphic interpretations.

Geophysical Data Acquisition Gateway: Tools for Planning, Tracking, Reporting and Collaboration
The increasing world demand of oil and gas led to raise hydrocarbon exploration in Saudi Aramco. The number of acquisition projects is increasing making it impossible to plan and monitor the progress of these projects manually.

G&G Business Capability Based Software Design and Architecture
More LessBusiness Capabilities is a modeling techniques used to model the services that a business or enterprise offers or requires. These capabilities are modeled in the Business Conceptual layer and represent what the business does (or needs to do) in order to fulfill its objectives and responsibilities.

An SOA Approach to G&G Computing Challenges
More LessMost of the oil industry have already made several steps along the road towards enterprise SOA, or at the very least already have a number of Web services deployed. Most of these companies have multiple platforms from multiple vendors, distributed across organization, administrative and trust boundaries.

Model-Centric 3-D Petrophysical Application Technology
Authors Roger R. Sung and Khalid S. Al-WahabiThe complexity and heterogeneity of reservoirs makes it extremely difficult to characterize and predict recovery. Oil industry geoscientists and engineers have made strides in developing advanced petrophysical algorithms and formation evaluation techniques to understand the fluid flow mechanisms.

Multi-Directional and Multi-Scale Fault Detection Using the Random Wavelet Transform
Authors Saleh Al-Dossary and Khalid M. Al-GarniWe introduce a new and effective method of detecting discontinuities or “edges” such as faults in seismic data. This new algorithm detects faults based on both the directional derivatives and on the redundant wavelet transforms (RWT).

Monte-Carlo Statics: A Stochastic Approach on Wide-Azimuth Middle-East Data
Authors Guillaume Poulain and Le MeurEstimation of surface-consistent residual statics on large wide-azimuth Middle-East data using a Monte-Carlo approach is a challenge. This non-linear method that uses Simulated Annealing to compute large magnitude statics is characterized by its efficiency. However, by using advanced methods like high performance computing, the computation cost of this algorithm can be drastically reduced.

Application of True-Azimuth 3-D SRME to Onshore Data — A Case Study
More LessThe processing strategy for the 3D prediction and subsequent elimination of long period surface-related multiple energy (SRME) on a 3D non-orthogonal land seismic data is presented. It is demonstrated that the new development of 4D Fourier regularization is critical in the pre-conditioning prior to the application of 3D SRME.

How Early Diagenesis Restrain / Enhance Fractures Development in Carbonates NFR? An Analogue Case Studies in Provence (France) and Maiella Mountain (Italy)
Nearly 85 % of carbonates reservoirs are naturally fractured and over 30 % of world’s hydrocarbons reserves are located in NFR (Naturally Fractured Reservoirs) in which fracture networks controls fluid flow and/or accumulation. Implicitly, we have to consider that a reservoir is fractured until proven otherwise.
