We perform operational tests on 100 percent of casing strings to affirm design parameters were met during cementing. These tests may include confirmation of cement return volumes and pump rates and pressures. We also perform confirmation cement testing (temperature, cement evaluation, cement bond and ultrasonic logs) on well surface casing strings and additional casing strings as required by state regulation or on a case by case basis. One hundred percent of our wells have met the regulatory requirements for cement integrity. Because of our rigorous cement testing procedures, no well integrity events have occurred on Newfield operated wells since 2011.
We monitor well integrity from well construction to completion and production over the life of the well. Read more about our monitoring assurances.
