Summary <br />8 profiles were collected and processed to show the thermal changes which occurred during the surface <br />casing cement job. The above graphs depict those events that correspond to the DTS TIME in "The <br />Sequence of Events" captured on May 15 and 16 2011. <br />We can clearly see that at 17:00 on the 15 of May an increase occurring after the pumping of the <br />nitrogen cement. The temperature at TD N 1974ft is 79.47 deg F at 17:00 on May 15 the following <br />morning at 8:59am T1P was surveyed again and an increase in the wellbore can be seen. TD N 1974 ft <br />increases to 96.51 deg F. <br />Not knowing the nitrogen cement properties SLB cannot comment on the cement job setting process. <br />What is clear from the DTS surveys above is that the wellbore is changing in temperature over time and <br />that this change can be attributed to the cement curing process. <br />
