In constructing the marine pipelines, the concrete weight coated pipes are used to create a negative buoyancy coating and its protection from the external mechanical damages produced by icebergs, trawl nets, anchors, dropped objects. So far, no requirements have been formulated for the determination of the stress-strain state of the concrete weight coated pipes laid using the stinger (S-lay) system. The structural analysis carried out in accordance with the standard requirements does not account for the negative b...

Faults can act both as seal and as pathways for fluid migration and therefore correct evaluation of fault zone properties is one of key element for conventional hydrocarbon reservoir management. Nevertheless, the unconventional plays deformed by faults became increasingly in demand for petroleum industry. Lower Paleozoic sediments in central part of Baltic Basin are considered as potential unconventional shale gas system. Key TOC-rich intervals in the area of interest are Caradoc Sasino Formation and Lower Llandov...

Previous researches have shown the possibility of using organic-mineral additive based on glyoxal for injection strengthening of soils in roadbases and engineering communications. Saponite containing material was used as mineral component in the composition. Saponite containing material is a solid phase, extracted from the circulating water suspension of the kimberlite ore dressing.

Pyrite is one of the main rock-forming components for Upper Jurassic-Lower Cretaceous black shale Bazhenov Formation. The correlation between pyrite and total organic carbon is found to be relatively high; however, some deficiencies of this hypothesis are discussed. Interlayers with high pyrite and low total carbon contents are encountered in the transition zone where the Bazhenov Fm. grades into Podachimov pack and into the underlying Georgiev Fm. The presence of pyrite in such layers is associated with the diage...

The most appropriate way to increase grip of bitumen with mineral materials is the use of adhesive additives which are slowing down the process of aging of bitumen due to oxidation and increasing durability of pavement. Adhesive properties of bitumen are important characteristics, as they are having a huge impact on operational properties of composite materials, such as asphalt mixtures. To understand the chemical behavior of the binder components interaction and improve adhesion to mineral components of asphalt c...

The current problem of the last decade in the world is the increase of oil production volume due to the extraction of its hard-to-recover reserves. The difficulty of its extraction is determined not only by the petro-physical characteristics of the oil-bearing formation, but also by the physico-chemical properties of the fluid itself. However, not all methods of enhancing oil recovery are ecologically safe. The most effective and ecologically-friendly method of soil purification from pollution by oil products is t...

The paper deals with the theoretical and practical analysis of the influence that the cutting direction of the bucket wheel excavator has on the digging forces acting on the wheel.

The paper analyzes physicochemical properties of liquid products of waste tyre pyrolysis, and attempts to assess their usefulness as fuel for diesel engines. Every year, the number of produced vehicle tires increases at a very fast pace. Used tyres turn into waste that is difficult to manage simply because, according to relevant EU regulations, vehicle tires should be subject to recycling. To a large extent, the problem of waste tyres management may be resolved by their utilization through pyrolysis. The processin...

This article is the continuation of the paper published at the conference SGEM in 2016. European product standards generally do not specify the qualitative requirements for individual product characteristics. EN 14695:2010, which deals with the waterproofing of concrete bridge decks, is not an exception. The national standard CSN 736242:2010 sets quality requirements for bitumen sheets. The type of the modification of bitumen coating is not considered in quality requirements of this standard - the mass modified by...

Aerogels production consists of two main stages: preparation of the gel filled with solvent (alcohols, acetone or hexane) by polymerization or sol-gel process and its supercritical drying. The most energy consuming and complicated from a technical point of view is the drying step [1]. Supercritical drying allows keeping the internal structure by preventing collapse of pores. Supercritical conditions require the use of expensive highpressure apparatus and the process rate is limited by diffusion within the pores of...
