Reservoir Testing During the Redrilling Campaign
Year: 1985
Type: report
Abstract: The redrilling program in EE-3A was initiated after failing to connect wellbores EE-2 and EE-3 with several massive hydraulic fracturing tests. These included injecting up to 5.6M gallons (21,200m3) of water into EE-2 and up to 2M gallons (7570m3) of water into EE-3. The redrilling trajectory was established after consideration of seismic events mapping during massive hydraulic fracturing in EE-2 and EE-3. The original wellbore trajectories along with the EE-3A redrilling trajectory are shown in Figure 1. Also shown in the figure are seismic event locations. As can be seen from the figure, the redrilling trajectory intersects the two major seismic zones created by previous pump tests. This memo discusses reservoir tests during redrilling up to the time of the successful connection. This connection was accomplished during Expt. 2059 and its results are discussed sesparately in memos by Kelkar (ESS-4-85-150), Murphy and Brown (ESS-4-85-137), and Robinson (ESS-4-85-151).
