This introductory article provides a synopsis of our current understanding of the form and dynamics of magma reservoirs in the crust. This knowledge is based on a range of experimental, observational and theoretical approaches, some of which are multidisclipinary and pioneering. We introduce and provide a contextual background for the papers in this issue, which cover a wide range of topics, encompassing magma storage, transport, behaviour and rheology, as well as the timescales on which magma reservoirs operate. We summarize the key findings that emerged from the meeting and the challenges that remain. The study of magma reservoirs has wide implications not only for understanding geothermal and magmatic systems, but also for natural oil and gas reservoirs and for ore deposit formation. This article is part of the Theo Murphy meeting issue ‘Magma reservoir architecture and dynamics’.

Oil And Gas Reservoirs

Quantitative interpretation (QI) is the geophysicist's endeavor to go beyond reservoir architecture. It is the effort to use geophysical measurements in understanding reservoir properties such as rock type, porosity, and fluid composition. QI often refers to the use of seismic amplitude analysis to predict lithology, porosity, and pore fluids away from the wellbore in oil and gas reservoirs. However, we can generalize and expand the concept of QI beyond seismic methods and beyond oil and gas reservoirs. In this special section, we feature five papers and cover not only seismic and well-log data, but also gravity and magnetic data. We address a hydrothermal reservoir in addition to several oil and gas reservoirs.

Physical Laws

The article is devoted to the development of the theory of nonequilibrium pressure and temperature fields in two-phase thermodynamic systems simulating natural oil and gas reservoirs. Such systems are classified as strongly dissipative, since the flow process is accompanied by the predominant action of internal friction forces. The studies carried out made it possible to significantly clarify the concept of thermodynamic processes and establish new physical laws governing the formation of temperature effects during fluid filtration in real porous media. It is shown that the maximum values of the temperature effect do not reach the value of the integral Joule - Thomson effect for any values of the parameters of the medium and liquid, and in real oil and gas reservoirs, temperature changes are several orders of magnitude smaller than those predicted on the basis of the equilibrium theory.

Underground Hydrogen Storage

The article proposes new methodological techniques for identifying and mapping true and false seals based on the data of geophysical methods, according to the main provisions of the theory of the three-layer structure of natural oil and gas reservoirs. Seismic exploration in combination with well logging makes it possible to control the storage volumes, determine the gas-water contact contour and obtain detailed models of the natural reservoir.
