Optimizing HTHP Cementing Operations Available to Purchase

Successful cementing jobs are critical to economically completing HTHP wells. BP and Schlumberger Dowell have consistently been successful cementing wells at total depths between 22,000′ and 23,000′ and maximum temperatures of 400°F. The proof of successful cement work is demonstrated with record production rates for the state of Louisiana and achieving isolation in sands with over 10,000 psi depletion. The optimization methods and approach will be discussed along with problems experienced and subsequent solutions. Over 15 such wells have been drilled in Louisiana during the last 5 years. This paper will also address the philosophy and procedure of cementing production tieback casing to the surface by reverse circulating.
