Khidirly-Bandovan structures have been studied through geological mapping, structural exploration drilling, geophysical methods (gravimetric, magnetic, electrical, seismic exploration methods) since the 1930s. Small amount of oil from different wells in the upper part of Productive Series (PS) and huge amount of gas fountain from Middle Absheron sediments have been obtained. As the interest to these areas had not decreased, the geophysical surveys continued during further years. Seismic exploration surveys were executed in Bandovan structure via Common Depth Point (CDP) method in 2004, refracted ray method and gravimetric exploration complex in 2006 and 3D seismic exploration works and gravimetric investigations with “Scintrex CG-5 Autograv” devices in 2016, correspondingly. In the result of analysis of distribution characteristics for local gravimetric anomalies, as well as 3D descriptions of new gravimetric data, up-to-date logs on tectonic state of Khidirly-Bandovan structure have been obtained and as the new oil-gas exploration objects, the west and south-west wings of these structures highlighted.

Since January 2000, 1m resolution satellite imagery has been commercially available from the Ikonos satellite. Recently, the Quickbird satellite also became operational acquiring images with running 70cm resolution. We commonly assume that new technologies, such as Ikonos and Quickbird, will displace traditional methods. This may be the case in the far distant future, but at the present time (and for many years to come) there is plenty of room for both high resolution satellite imagery and traditional aerial photography. In fact, air photo use is steadily increasing as spatial information systems gain popularity in industry and government.

The article states the principles of layered media velocity modeling and the results of computer modeling of the value distribution of the vertical velocity of seismic waves in the central part of the Dnieper-Donets Basin. The computer model is used to integrate the seismic survey data, and to enhance the efficiency of seismic exploration for oil and gas. It is achieved through the application of new technologies for data processing with respect to velocity anisotropy, as well as through the use of traditional approaches.

Due to complicated near-surface conditions, including large elevation changes and complex geologic structures, accurate imaging of subsurface structures for hydrocarbon exploration in the foreland basins of western China has been challenging for many years. After decades of research and fieldwork, we developed an effective seismic exploration workflow that uses the latest technologies from acquisition to imaging. They include 3D high-density and wide-azimuth (WAZ) acquisition, 3D true-surface tilted transverse isotropy (TTI) anisotropic prestack depth migration, and dual-detachment structural modeling and interpretation. To further reduce uncertainty in velocity model building and improve imaging quality, our geologists, geophysicists, and reservoir engineers worked closely through the exploration cycle (seismic acquisition, processing, and interpretation). This exploration model has been used successfully in hydrocarbon exploration of many complex foothill areas in western China. Three-dimensional WAZ high-density seismic surveys have been conducted over 40,000 km2 of the foreland basins, greatly improving the field seismic data quality. After application of 3D true-surface TTI anisotropic depth model building and imaging with integrated structural interpretation, new discoveries of hydrocarbon reservoirs have increased. The application of new technologies not only increased drilling success but also reduced depth well-tie errors between seismic data and wells.

Exploration And Development

The technical problems existing in deep well drilling are becoming more and more predominant during the exploration and development of oil-gas field. The poor formation drillability, low drilling rate and complicated pressure system cause the underground accidents frequent, extend well construction cycle, and make the cost of the project much higher. Therefore, it is urgent to develop new technologies to improve the efficiency of the exploration and development in deep unconventional oil-gas reservoir. The particle jet technology is a new energy-saving way which has a broad application prospect. It can take the way of sucking in particles in annulus space to cycle use the particles, and promote the drilling rate. The feasibility of particle jet as a drilling medium is verified by the theoretical and experimental study, which provides the basis for the design of particle jet tool.

Marine Seismic

The design of successful marine seismic surveys is driven by many factors, two prime issues being efficiency and environmental impact. Efficiency is primarily driven by reduction of non-productive time and creating the largest sub-surface illumination area possible in the shortest time. In addition, public opinion and governmental regulations are requiring the industry to minimise their environmental impact. One aspect is reducing the overall sound exposure level (SEL) of the source into the marine environment. Using recent Australian examples, we will discuss and demonstrate the use of two new technology groups that address these concerns. The first is the use of a new type of seismic air-gun with optimal output over the range of frequencies commonly used in seismic exploration, while limiting potential environmental effects from unnecessary high-frequency emissions. The second is continuous data acquisition along the entire boat traverse, including the turns, thereby reducing non-productive vessel time. Both are described with examples from a recent survey acquired offshore north-west Australia.

Development of technologies, growth of trends of reducing impact on environment and challenging tasks, which oil and gas producers face, make introduction of new technologies in seismic exploration field unavoidable. As a key tool of prospecting, exploration and reconnaissance of hydrocarbons, seismic exploration is usually restricted by terrain conditions. Urban, wooded and marshy lands, protected areas, river valleys, mountain areas often make seismic exploration impossible or signifi cantly impact its quality and efficiency.   One of the modern trends enabling resolution of the issues related to impact on environment is to switch to cable-free registration systems (wireless seismic), so called low impact seismic. Due to the use of cable-free equipment, this new technology makes it possible to reduce impact on environment during field works, as equipment is delivered to the place of installation with no special heavy machinery involved.  On the other hand, cable-free systems of seismic acquisition allow to resolve complex tasks of exploration and appraisal studies. Firstly, carry out exploration of hard-to-reach territories, including protected environmental areas, which until now remain unexplored or slightly explored. Managing seismic cables in such conditions is very complicated or impossible. Cable-free technologies allow easily resolving such issues due to both minimum impact on environment and simple and quick placement of receivers. Flexibility and easy scaling of wireless seismic adds to its advantages versus conventional survey. Kilometres of wires are not needed, which allows to easily increase the number of receiver channels and conduct high-density full azimuth seismic survey with single seismic receivers at deep structures, thus, significantly increasing quality of the data received.  The pilot project successfully completed at Khoroshivska area by joint efforts of DTEK Oil&Gas LLC and LLC Denimex Geo LLC confi rms in full advantages of wireless solutions revealing new opportunities for the use of seismic exploration at areas previously hard to reach and allowing implementation of high density acquisition projects.

As a type of carbonate reservoir and main oil-gas production formation in the Tarim Basin, China, fractures and paleokarst caves in Ordovician limestone are the targets of interest for seismic exploration in the S48 well area. Although conventional 3D, high-density, and wide-azimuth seismic acquisition has been widely applied in the Tarim Basin, we still need to determine what 3D 3C seismic data can further do for the characterization and fluid detection of the carbonate reservoir. In the S48 well area of the Tahe oilfield, we had acquired 3D 3C seismic data with single digital 3C sensors at the same grid, whereas the traditional 1C acquisition had arrayed geophones. Through comparison and analysis of two kinds of seismic data, including field records and migration profiles, some important characteristics can be found: (1) The [Formula: see text]
