... of a large oil field. The key objective in this work was to determine the long-term reserves recovery efficiency in the wells with different orientations of their horizontal boreholes. In order to assess the inflow profile and composition in the horizontal wells, the dynamic marker-based production profile...

... Abstract This paper presents a team behavioural marker framework that categorises and defines team-based non-technical skills which are then used to observe, record, and debrief team performance. Some oil & gas companies have proactively taken steps to address non-technical skills...

... ABSTRACT: The possible influence of the well case on the compaction measurements made in producing gas/oil reservoirs by the Radioactive Marker Technique (RMT) is investigated. The issue is a very important one as RMT data are currently used to derive the vertical rock compressibility M c, i.e...

... Abstract Radioactive Marker Technique (RMT) is a systems to evaluate layer compaction and land subsidence due to underground fluid production, based on the periodic monitoring of the distance between markers inserted into the formation, or onto casing. RMT is designed for the in situ...

... to investigate the thermal history of less well understood sequences. Such studies of the distributions of so-called biological marker compounds can, therefore, be used alongside other approaches to provide information about the minimum thicknesses of Sediments required for the formation of commercial...

... Abstract. Novel biological marker parameters are applied to problems of geochemical correlation of crude oils and source rocks in the area of Prudhoe Bay Field, Northern Alaska. The molecular structures used for fingerprinting the shale extracts, the kerogen pyrolyzates, and the crude oils...

... ABSTRACT As the setting environment of navigational markers will be affected by strong wind, rain and other bad factors, and even there are hidden dangers of collision of ships, the working status of navigational markers will change. In order to realize the accurate study and judgment of its...

... Summary Traditional methods of inflow profile monitoring are not always effective, especially when tight reservoirs are considered. One of the most progressive solutions is the use of marker technologies based on the markers' selection and subsequent identification in fluid taken at wellhead...

... of wells. With accurate geomechanical modelling such issues can be assessed and proactively mitigated. Measurement of changes in distance between radioactive markers is a recognised technique for compaction monitoring. The measurement is undertaken throughout the life of the well and is used...
