Abstract
For a geothermal project in France, our customer planned to cement 7” glass reinforced epoxy (GRE) tubulars in old corroded 9 ?” carbon steel casings. Through extensive laboratory research, Fangmann Energy Services developed and applied a new low-weight cement system specially customized to isolate the annular interval. The premium quality of the first trials and hence the supreme adhesion efficiency of this state-of-the-art system onto GRE and steel surfaces was verified by cement bond logging.
