Method of controlling and/or inhibiting strength retrogression during cementing
Cementitious slurries capable of controlling and/or preventing strength retrogression during the cementing of a formation contain a bismuth salt or derivative thereof. Bismuth trioxide is preferred. The cementitious slurry may further contain a density modifying agent and/or strength enhancer. The c...
