Here, we suggest a new algorithm to study the local fractal properties of airborne spectrometric data considered as 2D-mBm paths. This algorithm is first validated on synthetic two-dimensional multifractional Brownian motion (2D-mBm) paths, and then implemented on natural Gamma rays measurements recorded in Hoggar (Algeria). The regularity (Holder exponent) maps obtained from the different channels (K, Th and U) show a strong correlation. Besides, these maps allow depicting the location of some faults affecting the studied area, especially the main 450' fault. Our findings show that the Holder exponent can then be used as a tool for the geological characterization. © 2014 The Authors.

This paper aims at summarizing the current extent and architecture of the former Mesozoic passive margin of North Africa from North Algeria in the west up to the Ionian-Calabrian arc and adjacent Mediterranean Ridge in the east. Despite that most paleogeographic models consider that the Eastern Mediterranean Basin as a whole is still underlain by remnants of the Permo-Triassic or a younger Cretaceous Tethyan-Mesogean ocean, the strong similarities documented here in structural styles and timing of inversion between the Saharan Atlas, Sicilian Channel and the Ionian abyssal plain evidence that this portion of the Eastern Mediterranean Basin still belongs to the distal portion of the North African continental margin. A rim of Tethyan ophiolitic units can be also traced more or less continuously from Turkey and Cyprus in the east, in onshore Crete, in the Pindos in Greece and Mirdita in Albania, as well as in the Western Alps, Corsica and the Southern Apennines in the west, supporting the hypothesis that both the Apulia/Adriatic domain and the Eastern Mediterranean Basin still belong to the former southern continental margin of the Tethys. Because there is no clear evidence of crustal-scale fault offsetting the Moho, but more likely a continuous yet folded Moho extending between the foreland and the hinterland beneath the Mediterranean arcs, we propose here a new model of delamination of the continental lithosphere for the Apennines and the Aegean arcs. In this model, only the mantle lithosphere of Apulia and the Eastern Mediterranean is still locally subducted and recycled in the asthenosphere, most if not all the northern portion of the African crust and coeval Moho being currently decoupled from its former, currently delaminated and subducted mantle lithosphere.

Arrival time picking is a critical step in the analysis of geophysical data. This study aims at improving the standard shortterm-average/long-term- average (STA/LTA) method using softthresholding denoising techniques based on the discrete wavelet transform. The suggested method has been first tested on simulated seismic traces. For the purpose of choosing the best parameters, we have investigated different analyzing wavelets, threshold selection rules ('minimaxi', 'universal', 'rigorousSURE', and 'heuristicSURE'), and threshold rescaling types (global and adaptive). It is shown that the best results are obtained using the Haar wavelet, the 'universal' rule, and the multiple-scale-dependent rescaling type. Afterward, simulated data sets with varying signalto-noise ratio (SNR) have been used to compare the wave onset times picked using both STA/LTA versions (standard and denoised) and the modified energy ratio (MER) algorithm. The results show that, for data sets with high SNR values (greater than three), the MER algorithm yields the most accurate arrival times whereas, for low SNR values varying from 3 to 1.5, the denoised STA/LTA algorithm is the most effective picking algorithm. Furthermore, the picking techniques have been applied on real seismic traces recorded in the Algerian Sahara. It is again confirmed that the proposed technique provides the most reliable picking for high-noise traces. To conclude, the denoised STA/LTA algorithm is a powerful tool for identifying the first arrival for high-noise signals with SNR values lower than three and can tolerate an SNR value of about 1.5. © 2013 IEEE.


Fracture density estimation is an indisputable challenge in fractured reservoir characterization. Traditional techniques of fracture characterization from core data are costly, time consuming, and difficult to use for any extrapolation to non-cored wells. The aim of this paper is to construct a model able to predict fracture density from conventional well logs calibrated to core data by using artificial neural networks (ANNs). This technique was tested in the Cambro-Ordovician clastic reservoir from Mesdar oil field (Saharan platform, Algeria). For this purpose, 170 cores (2120.14. m) from 17 unoriented wells have been studied in detail. Seven training algorithms and eight neuronal network architectures were tested.The best architecture is a four layered [6-16-3-1] network model with: a six-neuron input layer (Gamma ray, Sonic interval transit time, Caliper, Neutron porosity, Bulk density logs and core depth), two hidden layers; the first hidden layer has 16 neurons, the second one has three neurons. And a one-neuron output layer (fracture density). The results based on 8094 data points from 13 wells show the excellent prediction ability of the conjugate gradient descent (CGD) training algorithm (R-squared. =. 0.812).The cross plot of measured and predicted values of fracture density shows a very high coefficient of determination of 0.848. Our studies have demonstrated a good agreement between our neural network model prediction and core fracture measurements. The results are promising and can be easily extended in other similar neighboring naturally fractured reservoirs. © 2013 Elsevier Ltd.

Algeria is on track to increase its natural gas output to 9 billion cubic meters a year after the country brings three stalled projects back online, according to the country's state-backed energy firm Sonatrach. According to media reports, the country will be able to increase its output following the opening of three projects in southwest Algeria. “The three projects will come online on time, the outcome will reinforce our position as a reliable gas exporter to Europe. No delays, the projects will be delivered in 2017,” a Sonatrach source told Reuters. Over the last several years, Algeria has struggled to sustain and increase oil and gas production amid an ongoing corruption investigation, management shake-ups at the state-backed Sonatrach, collapsing global pricing and fading confidence among vital foreign production partners. While the country largely escaped the sort of political and security unrest that left neighboring Libya struggling, it has faced some spill-over from regional incidents and questions about its long-term political leadership. According to the report, Algeria currently stands as the third largest gas provider to the European Union, which has worked to cultivate production agreements with North African providers in recent years to help ease dependence on Russian imports. The report outlines the efforts as the Touat Gas project in February of next year, the Timimoun in March 2017 and the Reggane in June of next year. “Further in the south, we have found a huge potential of gas around the fields of Akabli and Tidikelt, in addition to Alrar’s project in the east that will deliver gas and oil,” the source told Reuters. In recent years, Algeria has worked to reverse its downward production trend by amending its energy laws to make it more appealing to foreign energy firms and recently held a summit with European Union officials to explore how to attract needed investment and increase involvement in the global marketplace.

Spain’s Compania Espanola de Petroleos SA (CEPSA) and Algeria’s Sonatrach have signed an agreement that will have particular relevance to oil field contracts in Algeria. CEPSA has maintained its exploration and production activities in that country for the past 30 years “without interruption,” the company said.

As part of a continuing effort to broaden the country's energy and financial base, Algeria has announced that it has signed an agreement to build a solar power plan in the North African nation. According to media reports, Algeria's state-backed energy firm, Sonatrach, has signed an agreement with Italian energy giant Eni to construct the plant as a means of reducing domestic consumption of gas. In addition to meeting local electricity demand, the plant would also free up more gas for the export market. Deeply dependent on energy revenue for government spending, countries like Algeria have been forced to cut spending and adjust generous subsidy programs to keep match the deep decrease in incoming revenue. The decline has forced a discussion of economic diversity among a number of energy producers, most notably Saudi Arabia as governments have been forced to eat into funds usually sustained and increased by oil and gas revenue. Any steps taken to reduce the amount of gas dedicated to local consumption would allow additional revenue for the country's government. According to the report, the 10MW plant will be constructed in southern Algeria, providing Eni's Bir Rebaa field with power, with construction scheduled to begin before the end of the year. In recent years, Algeria has struggled to maintain a consistent and reliable oil and gas industry, with a number of vital foreign partners exiting the country due to concerns about political and financial stability. The loss of interest on the part of foreign partners and its impact on production levels would be of concern in any country, but Algeria’s is of grave concern considering the country’s heavy dependence on oil and gas for 97 percent of their export revenue and substantial amounts of government operations and spending. In 2014, the country's leadership announced plans to invest about $100 billion into the country’s energy sector from through 2020. The plan was intended to increase local reserves, increase new exploration efforts and boost the country’s new shale efforts.

Faced with dwindling state coffers thanks to a sharp decline in oil prices over the last two years, Algeria is seeking out any solution possible to boost its energy revenue, including inking a new supply deal with Italy. According to media reports, the agreement will provide Italy with 10 billion cubic meters of natural gas each year, covering about 16 percent of the southern European country's demand through the Transmed pipeline. The agreement also moves to strengthen ties between Algeria's state-backed Sonatrach and Italy's Eni, which is currently active in the North African state. The deal comes as Algeria is moving to close the revenue gap left by a crash in global crude prices. According to a Bloomberg report, the downturn in prices has left the country scrambling to slow the bleeding, which has seen its state fund collapse 87% since 2003. "At current prices we won’t be able to survive two years,” said Mohamed Said Beghoul, a former director of Sonatrach. "There are some billions in foreign reserves but they risk to melt like snow in eight to 10 months if the price of the barrel stays as it is." Over the last several years, Algeria has struggled to sustain and increase oil and gas production amid an ongoing corruption investigation, management shake-ups at the state-backed Sonatrach, collapsing global pricing and fading confidence among vital foreign production partners. The country has moved to introduce legislation to help ease the process of investment and production among foreign energy partners, but with prices low, these efforts have been far from successful. Earlier this fall, the country also moved to increase its natural gas output to 9 billion cubic meters a year by bringing three stalled projects back online. “The three projects will come online on time, the outcome will reinforce our position as a reliable gas exporter to Europe. No delays, the projects will be delivered in 2017,” a Sonatrach source told Reuters. However, with oil prices still low, it's unclear, how much time Algeria has to reverse course and close its state funding gap.
