ABSTRACT

A B S T R A C T : The parameters, being subject of measurement during the C 0 2 sequestration into the

Upper Silesian coal seams under the R E C O P O L project can be divided into three groups: technolo-

gical, safety and environmental-ones. The technological parameters mainly refer to the constant

monitoring of the pressures inside the C 0 2 storage tanks, at the inlet and outlet of the pump skid, at

the injection well wellhead, periodically inside the well (at different depths - by the pressure gau-

ges). Apart from above also temperature at the wellhead and the flow of C 0 2 are being constantly

measured. A s far as safety parameters are concerned they can be divided into two groups again: the

surface and the underground-ones. The underground parameters are very important as they refer to

the constant monitoring of C 0 2 content in underground workings of the neighbourhood coal mine

"Silesia". The surface safety parameters measurement is focused on periodical measurement of

M S - 4 well gas content, its concentration and flow, measurement of water level in the a.m. wel l , its

P H and conductivity.
