Halliburton (NYSE: HAL) announced it successfully completed three wells in the deepwater Gulf of Mexico using its Enhanced Single-Trip Multizone (ESTMZ) FracPac System. The technology was developed in collaboration with Chevron U.S.A. Inc. (NYSE: CVX) as the companies worked to complete two field trials and several system integration tests.
The downhole tool system allows an operator to stimulate and gravel pack multiple production zones in one trip for the highest treating rate with the greatest volume of proppant, Halliburton said.
Completions were made in Chevron-operated wells and saved Chevron an average of 18 days and $22 million.
Efficiency and production was increased because the ESTMZ system allows more materials to be stimulated at once and in a shorter period of time.
"In addition, this system allows us to deliver a very aggressive stimulation with rates up to 45 barrels per minute and volumes greater than 400,000 pounds of 16/30 high strength proppant," said Senior Vice President of Halliburton's Southern and Gulf of Mexico regions Ron Shuman. "Having to make multiple runs in and out of the wellbore equates to a large expense for operators."
