Problems associated with asphaltene deposition are key challenges for the upstream industry. In this research work, systematic experimental studies of asphaltene precipitation were conducted for two different Iranian crude reservoirs. Though gas injection in the reservoir enhances the crude productivity, it leads to higher precipitation of asphaltene compared to the natural depletion conditions. State of the art software tool namely CMG was utilized to predict the performance of the reservoirs for natural depletion condition as well as at high gas injection conditions. The CMG based predictions matched well with the experimental observations for both the reservoirs with reasonable accuracy. © 2019 Petroleum and Coal.

Experimental and CMG study of asphaltene precipitation under natural depletion and gas injection conditions

Geomorphic signatures in parts of Koyna region were analysed using satellite images and morphometric indices (stream length gradient index and valley width to height ratio) with limited field checks in key areas for understanding the role of tectonics in this seismically active zone. The Koyna River zone, particularly downstream of Koyna dam wall up to Kajali Nadi, is characterised by incised narrow valleys, steep escarpments and structurally controlled drainage. Presence of knick points at consistent elevations between 825 m to 675 m, steep gradients in an otherwise gradual longitudinal profile and valley width to height ratio less than 1.0 suggest readjustment of the streams along NW-SE and N-S directions. The escarpment slopes in general have en echelon arcuate ridge pattern ∼ N45°-N 225° in the western part, and then becomes ∼N 10°- N 190° near Donachiwadi, almost orthogonal to the E-W Koyna River. The Donachiwadi fault runs parallel to the escarpment slopes observed near Kodoli. The fluvial system in Koyna thus indicates rejuvenation controlled by basement propagated structures. © 2017, Geological Society of India.

The deformed sedimentary sequence exposed in the core of Precambrian Kaladgi Basin, North Karnataka India, has given rise to prominent regional basinal structures with intervening anticlines. Deformation ceases away from the core part. The basinal structures are recognised on satellite images, aerial photographs and toposheets because of resistant segmented ridges of quartzite. A closure view of Bhuvan images around Yadwad village, North Karnataka, the core portion of Kaladgi Basin also revealed presence of folded geometry in the older carbonates of Bagalkot Group seen along the margins of the regional folds. Though folding in the sequence exposed in the region around Yadwad and further west is described by many authors, no detailed analysis of structures is available in published literature. An attempt is made here to map, analyse and integrate the structures in carbonates of Yadwad region on different scales observed in the field to find out their possible origin. It is suggested that the structures are syntectonic in origin formed in the presence of circulating fluids in high pressure and low temperature during the post depositional phase the Bagalkot sequence in which gravity played an important role in the formation of regional structures. The sequence also has recorded low grade of metamorphism as seen from the thin section observations.

Analysis of Folding in the Proterozoic Sedimentary Sequence of Bagalkot Group Exposed around Yadwad, N Karnataka, India: a Study Based on Remote Sensing Techniques and Field Investigations

In the present study, degradation of petroleum industry wastewater has been investigated through laboratory experiments by employing heterogeneous photocatalytic process. A photocatalytic reactor was used for the advanced oxidation. The industrial wastewater was characterized. Photocatalytic activity of semiconductor such as titanium dioxide (TiO2) has been investigated. An attempt has been made to study the effect of process parameters through amount of catalyst, and operating pH on photocatalytic degradation of petroleum industry wastewater. The experiments were carried out by varying pH (2-11), amount of catalyst (0.25-1.5 g/L). Optimal suspended catalyst concentration, fluid pH and temperature were obtained at amounts of near 1 g/L, 3 and 50 °C, respectively. The maximum rate of degradation was observed in acidic medium at pH 3 and maximum reduction in chemical oxygen demand (COD) of 60%. © 2015 Scientific Publishers.
