Fixtreng-230
Fixtreng-230 agent is powdered sand that helps oil well cement maintain low permeability and high compressive strength under high-temperature condition. Fixtreng-230 agent is recommended for use in cementing wells where static temperatures exceed 230°F. Above this temperature, most cement compositions exhibit satisfactory compressive strength after the initial set but will rapidly lose strength after continued exposure to high temperatures. Fixtreng-230 agent helps prevent this problem by chemically reacting with the cement at high temperatures. Fixtreng-230 agent has been widely used in thermal recovery wells in combination with refractory-type cements.
