HALLIBURTON SETS WORLD RECORD ON REVERSE CIRCULATED FOAM CEMENT JOB IN WYOMING
-Reverse foam cement job saves operator time and money-
DALLAS, Texas - Halliburton Energy Services, a business unit of Halliburton Company (NYSE: HAL), recently completed the world's deepest reverse circulation ZoneSealSM (foam) cement job for Moncrief Oil Company of Fort Worth, Texas. Located in Natrona County, 50 miles west of Casper, Wyoming, the total depth of the well was 15,932 feet with the tight wellbore geometry of 10 ¾-inch pipe in a 12 ¼-inch hole. The well had 7,132 feet of open hole exposed (8,800 feet of 13 5/8-inch intermediate casing) with an invert drilling fluid system. The bottom hole static temperature was 260 degrees Fahrenheit, while the BHCT (Bottom Hole Circulating Temperature) was 215 degrees Fahrenheit.
"With this procedure, we were able to circulate cement in a single stage and eliminate a tie-back string, resulting in the integrity of the wellbore" said David Kessel, drilling and production manager for W. A. "Tex" Moncrief Jr., Independent Oil and Gas Producer of Fort Worth, Texas. "Halliburton's teamwork and flexibility exhibited at the Natrona County well helped us save both time and money," added W. A. "Tex" Moncrief Jr., Independent Oil and Gas Producer of Fort Worth, Texas.
The HES Zonal Isolation and Logging Services team faced a number of challenges due to the characteristics of the well. The cement, in a normal circulation route, would be over-retarded at the surface and might not set up. In addition, the string was intended for both fracturing and production, requiring competent cement on the annulus, and the ECD (Equivalent Circulating Density) was limited to approximately 11.5 ppg (pounds per gallon).
The Heat Suite™ tools demonstrated the ability to provide essential cement position information in the wellbore in a reverse circulation process while being able to operate at greatly elevated temperatures approaching 425 degrees Fahrenheit. Using the logging tools in this method was a unique treatment of the technology.
The HES teams also reverse circulated the foam cement into place to prevent exceeding the fracturing pressure of the bottom zones. Using the OptiCemSM, ZoneSeal, and Heat Suite procedures, optimum material and process performances were achieved.
"As an energy service company, we are committed to helping our customers to resume operation as quickly and efficiently as possible," said Dick Cheney, chairman and chief executive officer, Halliburton Company.
