sch.2-sec.7 Cement to be used for plugs

A geothermal well must have a surface plug of cement in the casing. Also, if a geothermal well has more than 1 casing string and any inner casing string does not reach the surface, the inner casing string must, if required to comply with section 5 , be plugged with cement at the top of the string. The cement used as a plug in the well must— be of an industry accepted grade, having regard to the salinity of the fluids in the surrounding strata; and be tested to ensure that it complies with industry accepted practices and standards. A plug in, or adjacent to, geothermal fluid in the well must, if reasonably practicable, be adequately secured.
