ABSTRACT A This study focus on reducing ice adhesion strength and prolonging the freezing time on the surface of equipment which service in a cold environment. We prepared anti-icing/icephobic coating by combining epoxy, amino-silicone and nano-SiO2 particles. It was found that the coating improved static contact angle (CA) and reduced contact angle hysteresis (CAH) obviously, which had close relation with ice adhesion strength and freezing time. Finally, we compared the coating with aluminum sheet, and found the coating reduced ice adhesion and prolonged freezing time obviously. This coating can be easily prepared on large-scale surface and suitable for polar ship and equipment. INTRODUCTION With increasing exploitation of the polar region, people start focusing on the durability of equipment that serviced in a cold and humid environment. Ice and snow accumulation result in some problems for those equipment, for example, increasing ship weight, adding ship resistance and fuel consumption, even effecting safety. There are several methods to reduce the damage of ice\snow accumulation such as heating, mechanical deicing, using deicing agent or anti-icing coatings. Compared to other methods, anti-icing/icephobic coating has many advantages: does not need energy consumption, environment-friendly, simple and convenient. Because of low surface energy and micro-nano hierarchical surface topography, superhydrophobic surface has low adhesion work and small contact area with ice or water according to Young-Duprรฉ equation and Cassie-Baxter equation. Therefore, it is considered to candidate for anti-icing/icephobic coatings (Farhadi, Farzaneh and Kulinich, 2011; Kulinich and Farzaneh, 2009; Saito, Takai and Yamauchi, 1997) In order to get low surface energy surfaces, researchers often introduce fluoro\silicone polymer with a large number of - CHx and -CFx groups into coatings, for example, polydimethylsiloxane (PDMS) and polytetrafluoroethylene (PTFE). Nishino, Meguro, Nakamae, Matsushita and Ueda (1999) developed the surface with the lowest surface free energy among all the materials in the world, based on the hexagonal closed alignment of -CF3 groups on the surface. The other key element for superhydrophobic surfaces is micro-nano hierarchical surface topography. There are a lot of methods to achieve micro-nano hierarchical surface topography, for instance, phase separation(Erbil, Demirel, Avci and Mert, 2003) , template method(Jung, Park, Choi, Lee, Park and Ruhe, 2002), sol-gel method(Tadanaga, Kitamuro, Matsuda and Minami, 2003), etching method(Shirtcliffe, Mchale, Newton and Perry, 2005) and chemical vapor deposition(Liu, Feng, Zhai, Jiang and Zhu, 2004). These methods are not as simple or inexpensive as particles-filled method. Karmouch and Ross (2010) made superhydrophobic wind turbine blade surface by deposition of silica nanoparticles embedded in epoxy. Its CA reaches to 152ยฐ, CAH is less than 2ยฐ. Huang, Hu, Yi, Liu, Li, Huang, Luo and Li (2012) developed hydrophobic and icephobic coatings by mixing silica and fluorinated acrylate copolymers, which has good hydrophobicity, icing delay performance and excellent thermal stability. Cholewinski, Trinidad, Mcdonald and Zhao (2014) prepared a kind of superhydrophobic bilayer coating containing PDMS-silica particles on top and an epoxy bonding layer at the base through a series of processes, and its CA is greater than 150ยฐ.

Abstract We aim to demonstrate the use of high-resolution sedimentological data during the early phase of the exploration cycle. The data reviewed included more than 1300 m of log sections taken North of Erbil. This was combined with field mapping, a microfacies study and the acquisition of routine core analysis data from plugs to provide a more complete analysis. Subsurface data included lithological information from two wells and 2D seismic lines with a total length of 487 Km. The study focussed on carbonate sequences including potential and known hydrocarbon reservoirs, notably the Qamchuqa-, the Shiranish-, the Khurmala- and the Pila Spi Formations. As a result a refined stratigraphic and depositional framework for the Lower Tertiary and Upper Mesozoic sequences has been established. The Cretaceous sequences analysed herein display a series of distinct lithofacies types ranging from shallow marine to deeper marine environments, which can be attributed to different main depositional complexes. The Paleogene sequences show a high diversity of lithotypes that relate to fluvial, fluvio-marine, mixed siliciclastic - carbonate shelf and inner platform depositional environments. Outcrop samples from both Tertiary and Cretaceous dolomites inherit the highest porosities thus presumably best reservoir quality in the subsurface. However, the effect of fracturing cannot be assessed in detail from surface data alone. A 3D facies model has proven useful in displaying the spatial relationship of the well and outcrop data. The display of facies probabilities improves the recognition of cyclicity within homogeneous dolomite sections. Possible extent and connectivity of geobodies could be assessed with the model. The results have been compared with, and put into a regional context with data from literature and proprietary selected subsurface data. The outcrop data have been incorporated into a workflow that supported other G&G subsurface disciplines during the exploration phase.

Abstract This case study involves a well drilled in the Erbil area of the Kurdish Region of Iraq, a region characterized by challenging geological conditions for drilling. To achieve the key drilling objectives, the drilling mud was made less dense by the addition of nitrogen into the mud column. In order to get a full understanding of the downhole conditions using this mud, the complete drilling process was modelled in real-time. The model was driven using a real-time WITSML data feed. This transient modeling software calculates downhole pressures, temperatures, torque and drag and cuttings density at all depths in the well bore in real- time, including the depths where there are no physical measurements. The transient model is continuously updated in real-time to reflect the drilling processes undertaken on the rig (e.g. pipe movement, mud pump activity, thermodynamics). Surface system variables including virtual mud pit levels are also calculated in real-time. The modelled data is then continuously compared to the sparse data points that are being recorded in real-time, allowing both a continuous calibration of the model with the "as drilled" well operation. The calculation of important drilling parameters such as sliding friction, rotational friction, and hydraulic friction is performed in real-time. The paper will present the key observations upon the matches between the modelled data and the "as drilled" data and summarise the key lessons learned during the well operations and the real-time modelling processes.
