The prospects of using lidar as an element of technical vision of underwater walking vehicles are discussed. Walking machines appear to be the most suitable for seabed conditions. The proposed elements have a number of advantages over more traditional image sensors. Shown are already existing patents applicable for use in seabed conditions. It is proposed to use lidars for a system of automatic recognition and determination of geometric dimensions of anomalies and structural elements of technological pipelines in the oil and gas industry.

This work involves the use of submerged arc welding (SAW) technique in joining heat treated steel in alternate arrangement. The selected as-received steel was initially cut, machined and heat treated to develop a conventional microstructure prior to joining operation. All samples were subsequently characterized to investigate the effect of the process on the mechanical behaviors. 3360 Instron Universal Tensile testing machine was used for the tensile properties evaluation; Vickers’ microhardness testing machine was also used for the hardness evaluation at various zones. From the result, it was found that interchanging arrangement of the microstructures during welding yield better combined properties of the ultimate tensile strength, yield strength and with improvement in the strain-to-fracture of some of the samples. The adopted mechanism was also observed to yield better hardness property on the sample. This led to the recommendation of this technique to the oil and gas industry that need to transport their products via the giant water bodies to clients.

Gas Industry

In the oil and gas industry, tracers are used to estimate residual oil saturation, to indicate the location and orientation of fractures in tight reservoirs, to identify and mark the direction of fluid flow in fractured deposits, to locate faults and discontinuities, and to measure fluid movement in injection wells during drilling. The tracers should behave in a mechanically similar manner to the tested substance, e.g., formation waters, oil or gas, and, on the other hand, they should significantly differ from them in terms of chemical properties so that it is possible to identify them. One of the fluorescent tracers used in the oil and gas industry, e.g., for inter-well tests during secondary or tertiary production methods (especially during reservoir hydration), is uranine. In order to assess the effectiveness of fluid movement measurements, it is necessary to determine the uranine content in formation waters. In this study, a method was developed to determine uranine in formation water samples using high-performance liquid chromatography with fluorescence detection (HPLC/FLD). The initial step in preparing samples for chromatographic analysis would be solid phase extraction (SPE). The method was validated and allows for the determination of uranine in formation water samples in the concentration range from 0.030 to 2.80 µg/L. The validation of the method included the analysis of factors influencing the measurement result (sources of uncertainty), determination of the linearity range of the standard curve, determination of the quantification limit of the method, and verification of the reproducibility, selectivity, stability and correctness achieved. The method developed within the study can be successfully applied in the case of the determination of uranine content in formation water samples from the oil and gas mining industry, which are often unstable and characterized by a relatively complex matrix. After validation, the method will also be applicable to the determination of uranine in matrices with a similar physicochemical composition, e.g., to assess groundwater flow in deformed carbonate aquifers or to characterize faults that act as barriers to horizontal groundwater flow.

Exploration And Production

Because the oil and gas industry has an increasing interest in the hydrocarbon exploration and development in the Arctic regions, it becomes important to design exploration and production facilities that suit the cold and harsh operating conditions. In addition to well-established minimum class requirements for hull strengthening, winterization should be considered as a priority measure early in the design spiral for vessels operating in the Arctic environments. The development of winterization strategies is a challenging task, which requires a robust decision support approach. This article proposes a risk-based approach for the selection of winterization technologies and determination of winterization levels or requirements on a case-by-case basis. Temperature data are collected from climatology stations located in the Arctic regions. Loading scenarios are defined by statistical analysis of the temperature data to obtain probabilistic distributions for the loadings. Risk values are calculated under different loading scenarios. Based on the risk values, appropriate winterization strategies can be determined. A case study is used to demonstrate how the proposed approach can be applied to the identification of heating requirements for gangways.

In many engineering applications, movement of micron and submicron size solid particles with compressed air or gas causes major engineering problems as in the case of black powder in oil and gas industry. Therefore, understanding its physical and flow dynamics characteristics inside a pipeline can be very useful to efficiently manage pipelines contamination issues. This paper presents an experimental study carried out to simulate characteristics of air-sand particles flow through a transparent horizontal pipe with various flow conditions. Experimental analysis focuses on determination of critical pickup velocity of the solid particles and measurement of pressure drop across the sand bed of various blockage ratios. Results have been compared with previous studies in literature. Limited experiments are conducted using black powder samples as well. Comparison of results shows vast deviation between sand and black powder behavior.

Potential Damage

The article is devoted to development of prediction methodology for potential damage from misuse of agricultural lands such as accommodation of oil and gas industry facilities, transport, infrastructure complexes, and emergency management. The purpose of the research is to propose a methodology for determination of potential damage to territory from misuse of agricultural lands. In order to do this, the following objectives need to be achieved: - group the sources of damage from agricultural lands misuse based on empirical evidence; - determine and classify the main types of damage and their periods; - develop the methodology and mathematical apparatus for calculation and prediction of damage extent on the “municipal district-region” level; - predict the losses from agricultural lands misuse in accordance with conditions of the Samara region. The proposed methodology allows one to more accurately assess the damage to large territories (district, region, country), which is essential to the work of administrative bodies. For calculation purposes, all cases of agricultural lands misuse are divided into four categories, each of which has its features of damage development. The obtained methodology was tested in the Samara region, where annually from 2.5 to 4.0 thousand ha of agricultural lands are used for other purposes than intended. Note that more than 20% of this number is removed from use for a long period of time (for more than 10 years). Oil spills account for 2.3-4.0% of land misuse. In 2021 the resulting damage could amount to 1.9 billion rubles.
