Drilling Progress at Citizen Green #1 Well

Completed open hole wireline logging with CMR-HNGS* tool string (run #2) from 7,562 to 3,600 ft (wireline measurements). Laid down wireline equipment from rig floor and derrick. Lowered drilling string into the well to condition hole and drilling fluid. Circulated drilling fluid. Pulled drilling string out of the well. Rigged up Schlumberger open hole wireline logging tools to collect fluid samples from formation (MDT Tool). Lowered MDT tool into well to 520 ft. MDT setting down, and could not be worked deeper. Pulled MDT out and laid down Schlumberger tools from rig floor and derrick. Lowered drill string, with drill bit into wellbore.

Notes/Observations

• Drilling fluid density at 10.2 pounds per gallon
• 4-1/2" casing delivered to well site

*CMR – helps determine injectivity of formations; HNGS – used to help determine mineralogy (rock composition)

Lowered drill string, with drill bit into wellbore to 600 ft. Encountered obstruction at +/-560 ft. Worked through obstruction until not observed. Pulled drill string out of the well. Lowered MDT tool into well to 630 ft. Pulled MDT tools out of well. Lowered drill string with bit into the well to condition hole and drilling fluid. Circulated drilling fluid. Pulled drilling string out of the well. Rigged up Schlumberger open hole wireline logging equipment. Lowered logging string into the well to 7,562 ft. Logged up from 7,562 to 6,600 ft with MSIP/ECS*.

• Drilling fluid density at 10.2 pounds per gallon
• MSIP (Modular Sonic Imaging Platform) = FMI** + Sonic***
• Logging tool pulled tight (tool dragging in hole) from 7,562 to 7,460 ft. No other tool drag observed through report time

*ECS – elemental captive spectrometry – used to determine mineralogy of rocks (combined with HNGS)
**Formation micro imager – gives an image of the rock
***Sonic scanner – sound traveling through rock – measures mechanical strength of rock
