5/20/2019 | If in future initial maximum injection volume of Navajo in Union Pacific 113x22 (API: 103-08606) is reached and operator requests additional injection volume then review and determine whether remedial cement squeeze is needed at the base of the Navajo in the U P R R 117x22 (API: 103-08667) well. An initial remedial cement job on Navajo in U P R R 117x22 was performed 7/18/2019. |

10/1/2019 | 1. Injection is not authorized until Subsequent Forms 31 and 33 are approved.
2. Retrieve water sample(s) from injection zone(s) before stimulating formation. Samples must be analyzed for Total Dissolved Solids at a minimum.
3. PRIOR TO PERFORMING OPERATIONS: Operator is required to contact COGCC to discuss acid and fracturing jobs. Approval of Form 4 may be required for acid and fracturing jobs. (As of 4/13/2016)
4. PRIOR TO PERFORMING OPERATIONS: Operator is required to contact COGCC to discuss Step Rate Test or Injectivity Test criteria for Maximum Surface Injection Pressure determination. Prior approval of Form 4 may be required for step rate and injectivity tests.
5. If not already in COGCC records operator required to provide all tops of formations encountered from surface to TD on a Form 5 if one is needed or on a Sundry.
6. Well must pass MIT witnessed by COGCC before Subsequent Forms 31 and 33 will be approved. Well in must be in injection configuration.
7. Operator must have approved eForm version(s) of Form 26(s) on file before Form 31-Subsequent and Form 33-Subsequent will be approved. Operator is required to file Form 26 updates on a quarterly basis if they have wells that need to be added or deleted. |

10/1/2019 | If the daily injection rate exceeds 10,000 barrels per day and if the area is not already monitored Chevron will be required to monitor for seismic activity in the Union Pacific 113x22 area. Chevron may be required to install a seismometer at a location to be determined by Chevron and COGCC. Chevron will be responsible for maintenance and operation of the seismometer. Data gathered by the seismometer will be made available to one or more third parties (such as the USGS, CU-Boulder, CSM, or CSU) for analysis. |
