Chevron completes 3 wells in deepwater GOM with multi-zone completion technology

Posted on 23 April 2013

Chevron has successfully completed three wells in the Lower Tertiary in deepwater Gulf of Mexico (GOM) with Halliburton’s Enhanced Single-Trip Multizone (ESTMZ) FracPac system. The two companies jointly developed the multi-zone completion technology and have conducted numerous integration tests and two field trials. Designed for use in deepwater and ultra-deepwater offshore completions, the ESTMZ system enables the operator to stimulate and gravel pack multiple production zones in a single trip.

For each of the three Chevron-operated wells completed with the ESTMZ system, time saved averaged 18 days, equating to approximately US $22 million.

“ESTMZ system allows more reservoir to be stimulated in a shorter amount of time, thus increasing efficiency, reliability and production, which is key to the success of the Lower Tertiary,” said Ron Shuman, senior vice president of Halliburton’s southern and GOM regions.

“In addition, this system allows us to deliver a very aggressive stimulation with rates up to 45 bbls/min and volumes greater than 400,000 lbs of 16/30 high-strength proppant. We deliver this with weighted frac fluid and 10,000 horsepower per interval for up to five intervals, providing a total cumulative proppant volume of greater than 2 million lbs per well with one service tool. Having to make multiple runs in and out of the wellbore equates to a large expense for operators. The ‘single-trip’ element of this system provides significant time savings with improved reliability and better asset optimization,” Mr Shuman concluded.

To date, Halliburton has deployed nearly 20 ESTMZ systems around the globe.
