We1-1 has reached total depth in Guyana

The company has announced they have successfully reached TD of 20 450’ on the Wei-1BP1 (Wei-1 bypass exploration and appraisal well). The original Wei-1 wellbore reached a depth of 19 142’. A bypass well (Wei-1BP1) was drilled from 18 757’ to TD and penetrated the primary Santonian targets of the well in the Western complex in the Northern portion of the Corentyne block.
Prior to the bypass, the well encountered an aggregate of approximately 71 ft of net oil pay in the secondary target reservoirs in the Maastrichtian and Campanian.
Following the bypass, data collected from LWD (Logging While Drilling) and cuttings indicate multiple hydrocarbon shows in the primary target reservoirs in the Santonian interval. Results from the well are encouraging: data acquisition is ongoing via wireline logging, MDT’s and side wall core sampling. An update on well results will be provided when the acquisition and evaluation has been finalised.
Results from the well are consistent with pre-drill expectations. The well has confirmed the company’s geologic and geophysical assessment of the block.
As operations continue, the joint venture has revised its total Wei-1BP1 cost estimates to approximately US$190-$195 million to complete the logging runs, finish well operations, and release the rig. The additional costs are primarily due to the lost sampling tool and the drilling of the bypass well.
