Abstract More than 300 million barrels of saltwater is produced everyday from oil and gas production wells. Most of this volume is injected through either saltwater disposal wells or used for water flooding and enhanced recovery purposes. Usually, the regulations require the injection to be conducted through the injector well tubing that is isolated from the well annulus to protect the underground source of drinking water (USDW) by preventing any possible leak through the well casing. Monitoring of the annulus pressure during injection ensures the well integrity. The annulus pressure changes can occur by one of the following mechanisms: thermal expansion of the annulus fluid; ballooning of the injection tubing; communication between the tubing and the annulus; or fluid migration behind the casing. Determining the communication mechanism can be a complex process and a need may arise to run several testing procedures and inspect all the wellbore components. Successful evaluation of the annulus pressure values and trends can directly identify the root cause of the annulus pressure buildup and simultaneously save time and reduce the cost associated with the workover operations. The seven case studies presented in this paper focus on the details pertaining to the annulus pressure buildup under different well conditions and purposes the interpretation technique for each case.

We consider modeling and geophysical interpretation of the obtained results in the oil and gas production problems. For solving these practical problems, we use combined finite element-differences method of resolving piezoconductivity problem with calculation of heterogeneous filtration parameters distribution of oil and gas productive reservoirs and oil-gas penetration conditions in the borders of the reservoirs. At that, we consider the main factors, which influence on the intensity of filtration processes near oil production well and gas production well respectively. These factors are important for effective supporting in practice high level of the oil and gas production. On the base of computer modeling, we have showed that intensity of filtration process near the acting oil and gas production wells mainly depends on oil phase and respectively gas phase permeability, as in close zone of well acting so in remote zone. The viscosity and reservoir porosity parameters in close and remote zones of the well action have little direct effect on filtration process near the acting well. However, these parameters can influence on the filtration process implicitly via direct acting on the respective phase permeability. We also have carried out analysis of the pumping well influence on the filtration process near production well in different practical cases.

The textbook describes the design features of offshore horizontal multi-hole production wells, as well as the bottom-hole components of horizontal multi-hole wells. The classification of complications of multi-hole horizontal wells, methods of their prevention and elimination are given. Methods of underground geonavigation of the development of offshore horizontal production wells are proposed. The geological and field bases of operation of horizontal offshore multi-hole oil and gas wells, modes and dynamics of oil, gas and associated water production, methods for calculating dynamic bottom-hole and reservoir pressures are specified. The technologies of operation of offshore horizontal multi-hole wells are presented. The composition and scope of environmental, field and research marine monitoring of the operation of offshore horizontal multi-hole wells and the protection of the marine environment in the production of oil and gas are justified. Meets the requirements of the federal state educational standards of higher education of the latest generation. It is intended for undergraduates of the enlarged group of "Earth Sciences" training areas, as well as for teachers, employees of the fuel and energy complex, industrial geological exploration and oil and gas production enterprises, scientific and design organizations.

AbstractMiniaturized single-mode thickness-shear pressure transducer combined with high-temperature SOI, silicon on insulator, integrated circuit technology is proposed as network-ready high-pressure high-resolution smart sensor for distributed data acquisition in oil and gas production wells. The transducer miniaturization is investigated with a full 3D computer model previously developed by the authors to assess the impact of intrinsic losses and various geometrical features on transducer performance. Over the last decades there has been a trend toward size reduction of high-resolution pressure transducer. The implemented model provides insight into the evolution of high-resolution pressure transducers from Hewlett-Packard™  to Quartzdyne™  and beyond. Distributed measurement in production oil wells in extreme harsh environment, such as found in the pre-salt layer, is an unsolved problem. The industry move toward electrified wells offers an opportunity for application of smart sensor technology and power line communications to achieve distributed high-resolution data acquisition.

The Cost

Deciding whether to buy new information to potentially improve the residual reserves of a producing oilfield, and what price to pay for the information, which may or may not actually improve the reserves picture, is a problem of some concern to field development and production economics. Here we show how the worth of obtaining new information depends not only on the reserves produced to date but also on the residual reserves still to be produced, on the probability that purchase of new information will indeed improve the known reserves, on the value estimated to be produced by the acquisition, and on the cost of the acquisition. There are also dependencies on production and lifting costs but these are not considered in detail here. The timing of a decision whether to acquire new data and how much to pay for it, are illustrated using total profitable gains made to date as a proxy for time. Two simple examples are worked through in detail so that one can see when the uncertainty of possible gains from newly acquired information are sufficient, relative to costs and the worth of residual reserves still to be produced, to allow management to make an informed and rational decision on whether to acquire and when to acquire new information in respect of the life of the field without such acquisition.

The proposed paper is a continuation and further development of the geological school of «Glavtiumengeologii » which is using today’s new bases of molecular geology of oil and gas, including regional researches, the influence of cosmic events, search and evaluation of resources, drilling of leading production wells and processing of hydrocarbon raw materials. The main aim of this is not just transfer of accumulated knowledges. Moreover, one of the aims is upbringing of ideology unconventional innovative technologies search via use of the fundamental laws of quantum physics and chemistry for description of discrete geological processes. Their testing on the scientific and industrial landfills in the drilled, idle, mothballed and abandoned wells will involves education of top managers, managers, engineers and other specialists for the development of nontraditional methods of work in the oil and gas production.

The paper analyses the situation with ensuring energy security in Russia over the past five years and provides an assessment of the nature of the transformation of the most significant threats to Russia’s energy security until 2030. It is shown that by 2030 the annual potential of fuel and fuel in the country Energy complex for the production of primary fuel and energy resources together with the import of fuel and energy to Russia will significantly exceed its domestic needs. At the same time, the ability to export Russian natural gas could be significantly reduced. The paper shows that the situation with the decline in opportunities for the production and export of natural gas in Russia is not very encouraging. There are no prerequisites for a significant increase in world prices for hydrocarbons until 2030. And at the same time, there is a constant increase in the cost of oil and gas production and transportation on average across Russia. The paper concludes that the possibilities for the development of the Russian economy through the sale of only natural resources are practically exhausted by now.
