| Country | : | China |
| Authors | : | Lianzhen Song |
Abstract: In view of the problems like low producing degree and prominent interlayer and areal contradictions appear during the process of water flooding development in fractured block D401 of Xinzhan oilfield, researches of fine fracture characterization，sedimentary microfacies subdivision and fine remaining oil by means of fine reservoir description have been performed to formulate personalized treatment according to the idea of partition adjustment. The block exhibits better development situation with water flooding control degree, water absorption ratio and fluid production proportion have been respectively enhanced by 6.5%, 8.6% and 8.9% after the implementation of indiscriminate infill, injection-production system adjustment, cyclic flooding, Subdivision and regroup, and the combination of the measures of 'adjustment，fracture and plugging' and super-short radius horizontal wells, which also provides reference for other fractured reservoirs.
Key words: fracture; personalized; indiscriminate infill; injection-production system adjustment; super-short radius; block D401

| Title | : | A Statistical Amplitude Analysis Method with Application to Streamer Data from the Niger Delta Offshore |
| Country | : | Nigeria |
| Authors | : | D.O. Ogagarue and C.N. Nwankwo |
Abstract: Multichannel processes in signal processing tend to 'smear' anomalously high and low amplitudes in the seismic data. Removal of traces with anomalous amplitudes in the earlier stages of seismic data processing is therefore expedient. In most cases, manual inspection of the gathers is carried out during trace editing, where any identified trace with anomalous amplitude is edited out from the record.........

| Country | : | Egypt |
| Authors | : | Esam A. El-Gawad || Mohamed Fathy and Mohamed M.Ali |
Abstract: The study aimed to combine the different available data to understand the subsurface system and the characteristic of Late Cretaceous reservoirs in El Diyur field to represent the vertical and lateral heterogeneity at the well, multi-well, and field scale, which could be used as a tool for reservoir management. Seismic interpretation was conducted on the seismic sections that concerned the study area to make a detailed structural interpretation to determine the structural geometry of the Late Cretaceous horizons. Petrophysical well log analysis of the reservoir rock of Abu Roash "G-10" and "G-20" zones have been done and mapped. The estimated volume of Original Hydrocarbon in Place of Abu Roash "G-10" and "G-20" zones have been calculated.

Abstract: Chittoor District is a hot and arid District, falls in rain shadow zone with a very low annual rainfall of 520mm. The recurrence of drought increased considerably and unless collective measures are initiated on a permanent basis the situation will become grim in future. Dosalavanka watershed in Chittoor District is selected to demonstrate the capability of high resolution satellite data in groundwater mapping at village level. This watershed is located in Survey of India toposheet No. 57 O/6. This watershed with an area of about 63 sq.km is underlined by hornblendebiotite gneiss and metabasalt traversed by dolerite dykes...........

Abstract: Remote sensing enhances the analysis of agriculture studies because of less time consuming, large aerial extent and sufficient support in ground studies. An attempt has been done to study rice crops canopy using the moderate resolution MODIS products. Five indices were assessed to monitor the crops throughout the season and they are Enhanced Vegetation Index (EVI), Leaf Area Index (LAI), Soil Adjusted Vegetation Index (SAVI), Weighted Different Vegetation Index (WDVI) and Stress related Vegetation Index (STVI)............

Abstract: The geotechnical properties of soils at a 44 year old hydrocarbon spill site were determined and the changes in soil properties due to the spill were evaluated. The aim was to assess the magnitude and intensity of hydrocarbon contamination and consequent modification of the geotechnical properties of the impacted soils. The study employed 2-D electrical imaging to assess the spatial extent of subsurface contamination, followed by sampling and laboratory testing of soils obtained from 5m deep auger borings...........
