COGIS - Best Management Practice Results

BMP Type	Source Document	Best Management Practices
Drilling/Completion Operations	Form: (02 ) 401173759 4/28/2017	An open-hole resistivity/gamma ray log was already run on the first well drilled on this pad (Yankee Federal B 1 – API 05-067-07127 – Doc ID 960790). The intermediate string for the pilot hole on this multi-well location will be logged with a cement bond log with cased-hole gamma-ray log from above the planned upper-most window into the surface casing.
Drilling/Completion Operations	Form: (02 ) 401173759 4/28/2017	Anti-collision evaluation was performed. Offset wells are operated by BP.
