Petrophysical evaluation of the Mars Field in the Dahomey Basin, Nigeria was done to identify and analyze petrophysical properties of the reservoirs in the field. This was achieved by the use of 3 wells from the field. This research determines the lithology, shale volume (Vsh), porosity (Φ), permeability (K), fluid saturation. Two hydrocarbon-bearing reservoirs age from three wells were identified which was then subdivided into different levels in this research. The average permeability value of the reservoirs is 20.0140md while porosity value ranges between 18%-39%. Fluid types within the reservoir were identified to be Gas, Oil, Condensate and water based on the Neutron-Density log motif. The petrophysical analysis of the field reveals that reservoir porosity ranges from 11-26%, hydrocarbon saturation ranges from 0.07-0.91, water saturation ranges from 0.93-0.09, volume of shale ranges from 0.09-0.22 and net-to-gross ranges from 0.46-0.878. From this research it was identified that the prolific reservoir within the Dahomey basin is within the Turonian and Cenomanian reservoir with good quality reservoir and producible hydrocarbon saturation.

In the article reflects the tasks of specifying the geological structure of the site as a result of the analysis of two-dimensional (2D) seismic survey data carried out in the Bulla-deniz area. On the basis of the studies carried out, the shape and dimensions of the Bulla-deniz structure, the planned state and amplitudes of tectonic faults were specified. It has been established that the structure is elongated in the NW-SE direction and changes its direction to the east in the area of the mud volcano. The seismic profile sections show that the seismic record is represented by a weak, sometimes chaotic, complex wave pattern due to the activity of a mud volcano and disjunctive disturbances in the area representing the southern crest part of the structure. There is rarefaction of isohypses from the northern crest part of the Bulla structure in the direction of the SE and NW of the pericline.

One of the main tasks facing the oil and gas industry of our republic is the issue of increasing and maintaining oil and gas production rates. The use of traditional impact methods does not allow to fully realize the existing potential of reserves that are difficult to extract. The article provides an analysis of the increase in production due to the drilling of wells completed with a ready-made filter on the example of the «Garbi Absheron» field.

Since most of the fields in the Absheron peninsula of the Republic of Azerbaijan are at the final stage of development, an inevitable reduction in hydrocarbon production is expected. It is planned to support oil production at the current level through the reconstruction of wells of the inactive fund. An increase in the proportion of formation water in well production, the presence of intra-reservoir, annulus and other cross-flows in this region, in most cases, is associated with inefficient isolation work. The development of effective recipes for cement slurries with controlled rheological properties is relevant. To regulate the rheological properties of cement slurries, the products of the company «Matanat A» «İzo-Sem» were used as an additive. In the course of the experiments, the influence of «İzo-Sem» dispersions on the physicochemical parameters of the cement stone was studied. When regulating the rheological properties of cement slurries with «İzo-Sem» additives, it is necessary to determine the effect of thermobaric factors on the values of these properties. In studies to assess the effect of temperature on the rheological properties of cement slurries with the addition of «İzo-Sem», they were carried out for the temperature range of 25÷75 °C. Dry mix of grout cement G-CC-1 (APİ Spec 10A Class G-HSR) was used in the studies.

In the article, based on the data of the fields in the final stage of exploitation, the most important complications that occurred during the production period and the methods of preventing these complications in the modern period were investigated. In particular, the methods of preventing of the sand plug and flooding, which are the main problems in this type of fields, were investigated and the significance of these methods of selective control against flooding was investigated, the most successful ones among these methods were shown, the hardening of the bottom hole against sand plug and the use of sand control screen in modern times were considered, in the hardening of the bottom hole the use of resin-containing components is mentioned.

The article is devoted to the development of innovative activity of industrial enterprises in the conditions of new industrialization, which determine the survival of a science-intensive business through the activation of the development and implementation of high-quality R&D, capable of creating high-demand science-intensive products both at the national and global levels. In the article, the authors expand the traditional approach to understanding innovation by introducing a new concept into scientific circulation - «innovative validity». On the basis of a comparative criteria analysis of such basic definitions of innovation management as innovation potential, innovation activity, innovation susceptibility, the place of innovation consistency in the practice of industrial enterprises is clarified, while it is justified that it is an evolutionary stage in the development of innovation activity in the chain innovation potential - innovation activity – innovative susceptibility – innovative viability. The article highlights the distinctive features of the innovative viability of a science-intensive business and offers a number of recommendations aimed at its institutionalization.
