Abstract
Introduction. It is known that during crystallization, water expands, which leads to an increase in the pressure of downhole water samples when they are cooled below 0 °C. At the same time, in open sources there are no quantitative estimates of the conditions inside the receiving chambers when they are frozen.
Materials and methods. Measurements of pressure and temperature of a downhole water sample during its cooling were carried out using an internal pressure and temperature sensor built into the piston of the sample chamber.
Results. The dynamics of PT-characteristics of a deep sample during its freezing is described. The pressure increase was 120.5 MPa upon cooling from 10 to -15 °C.
Conclusion. For the first time in the public domain, a quantitative assessment of the increase in pressure of a downhole sample during its cooling is presented. Information on the requirements for temperature regimes of storage and transportation of samples is summarized, priority areas of R&D are proposed to reduce risks when working with downhole samplers.
