The squeeze perfs are in the unperforated Raton formation. The Vermejo production perforations and another vertified casing leak, at 1600', are below a cement retainer set at 1565'. The Raton formation will be completed and produced in the Marble well when the price of gas increases and the economics for this work become more favorable. Pioneer requests permission to leave the wellbore as is with the leaking squeeze perfs since an attempt to squeeze the perfs will most likely fail and could damage the wellbore eliminating the potential for Pioneer and the State of Colorado to receive any future benefit from the Marble. 400297058 400297058 FORM 5A SUBMITTED 400297058.pdf 400297058 400297073 WIRELINE JOB SUMMARY 6-11-2012 The Perforators job ticket for CIBP - Marble 34-33.pdf 75830 400297058 VRMJ N 2121 2286 72 0.48 N --- TO TEMPORARILY ABANDON VIA CIBP SET AT 1565' AS DETAILED BELOW --- CIBP 2012-06-11T00:00:00-06:00 N 1565 TA Thread was being aborted.
