Bridge Resources Corp. announced that the Bridge North Sea Ltd Durango 48/21a-4z well, drilled by ENSCO 100, has confirmed highly porous gas bearing reservoir.
The top of the Leman Sand reservoir was penetrated on prognosis four feet high to the original 1967 48/21-1 discovery well located 350m east that tested 20.8 mmcfgd and 628 bopd. The sand in the current well has excellent reservoir properties from logging- while-drilling results coupled with high C1 through C5 gas shows.
The original well was a vertical bore whereas the current well bore is angled at 89 degrees for a 700 feet penetration across the top 15 feet of the reservoir. The lowest point at the end of this near-horizontal penetration will be 55 feet above the gas-water contact to minimize water production later in field life. Over 300 feet of reservoir has been penetrated by report time.
The well completion phase will include the installation of the fully-completed sub-sea well head and tree. The well will then be flow tested to acquire detailed gas and condensate parameters for final design modifications to the host Waveney Platform 14.3 km northeast.
The flow testing of the well is expected to be completed over the next few weeks and results of the testing will be released when complete.
