{"title":"The results of complex interpretation of seismic survey and well data in Gurgan Deniz area","authors":"L.J. Abilhasanova, P.J. Abasova, L. F. Hasanova","doi":"10.37474/0365-8554/2022-10-10-14","DOIUrl":"https://doi.org/10.37474/0365-8554/2022-10-10-14","url":null,"abstract":"As a result of combined analysis of seismic surveys conducted in Gurgan-deniz and neighboring areas and logging data as well, the geological structure of the studied area was specified, various seismic attributes (both as by seismic cubes and by separate seismic surfaces) were calculated. To have a clear insight about the lithofacies variability of the studied area, corresponding 3D models have been developed.  With the purpose of restoring the sedimentation conditions, a facies analysis of the area based on the visual study of the length and configuration of seismic reflections, as well as seismic amplitudes has been carried out, the changes of the power of separate intervals in which we are interested have been studied and the logging of the facies conducted. To define the connection between the dynamic parameters of seismic records and geological properties of the area in the promising intervals, several attributes (Sweetness, RMS, Instantaneous Frequency, Variance etc.) have been calculated and analyzed. The calculation have been conducted in a large diapason for all productive horizons (marked as potential reservoir). Sharp changes in the composition of rocks in the studied area are associated with a periodic transgression and regression, as well as with the fluviation. Three types of geological phenomena may occur during specific periods of cycle turns of rising and lowering of sea level: progradation and regression (recession of the sea), retrogradation or transgression (sea movement towards shore) and aggradation (comparatively stable state of sea level). In the view of sharp variation of lithologic composition of the sediments, predominantly in the bottom of Productive Series (PT), we can conclude that highlighted facies are characteristic for specific parts of the studied area. When highlighting the facies, the direction of sedimentation material brought by the rivers and source of nourishment has been revealed. According to the results obtained, we suppose that almost each lithofacies type has its own distribution area. Therefore, the fluviation plays a significant role in the distribution of the facies in the studied area of the Caspian basin, as well as in the accumulation of hydrocarbons. Complex research surveys carried out enabled to mark specific perspective oil-gas bearing objects in Gurgan-deniz and neighboring areas.","PeriodicalId":8668,"journal":{"name":"Azerbaijan Oil Industry","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81287052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are neither justified physical criteria nor accurate methods of estimation of supporting quality, as it is quite troublesome to set well conditions while conducting experimental works towards specifying the large number of the factors simultaneously affecting the longevity of well support. In this regard, there is no generally accepted method of testing backfill materials and the issue of necessary sustainability of stone from various bakfill materials designed for cementing of columns and setting cement bridges is not solved as well. Leading drilling service companies (Schlumberger, Halliburton etc.) of the world do not use special cement types and instead, prepare their own mixture for each cementing process on the basis of cement of selected for these oil-gas fields. As a result of mixing various types of weighting agents and other additives with base cement, a backfill system necessary for specified well is obtained. These systems are produced on specially equipped facilities in the world. The researches carried out justify that it is possible to obtain high quality simplified and weighted cement slurries on the basis of domestic raw materials with state-of-the-art technologies and equipment.","PeriodicalId":8668,"journal":{"name":"Azerbaijan Oil Industry","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75529120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to this, the reliability of gas pipelines in the operation is defined by a criteria of strain-stress state occured on these lines. The methods of technical diagnostics based on the up-to-date technologies should be implemented for revealing probable damages within the pipelines and equipment as well. Smart-of-the-art software technologies for performing calculations have been used in the research surveys.

As a result of such a conditional distribution, an attention is paid to the necessity of appropriate estimation of operation resource, quality standard and technical condition of the pipelines in the first group. Although the classification partly characterizes the technical condition of the pipelines, it is quite a practical diagnostic tool in the struggle against the decrease of reliability and quality of the subsea pipelines operated in recent 20-30 years in the complicated offshore conditions with increasing probability of failures and risks in transportation system. Offered classification covers all subsea pipelines used in the development of offshore fields, as well as can serve for improvement of their operation reliability.","PeriodicalId":8668,"journal":{"name":"Azerbaijan Oil Industry","volume":"68 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91121315","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
