Water Analysis

A range of “water” analyses are in the WCR; KCL content indicates all such fluids are effectively 100% mud filtrate.

Whole Oil Analysis

Oil was recovered on RFT (at 2708m) but there is no analysis in the WCR.

Comments

Located 2.9 km west of Montara 1 and 17.4 km SE of Swift 1, testing a western culmination on the Montara structural complex. The well encountered a gas and oil column in the Montara Formation reservoir target, but reservoir properties are poor, and the well failed to flow on DST. Permeabilities indicated from RFT are suspect.

What is an LAS file?

LAS (Log ASCII Standard) is the petroleum industry's standard format for storing and exchanging well log data. Developed by the Canadian Well Logging Society, LAS files contain header information about the well and columns of numerical log data at regular depth intervals.
