Arrow Exploration Corp. encountered hydrocarbons at Rio Cravo Este (RCE) field on Tapir block in Llanos basin, Colombia.
RCE-4, the fifth well drilled by Arrow in the block, reached 8,546 ft total depth (8,053 ft true vertical depth) Mar. 8, 2023. The well encountered six hydrocarbon bearing intervals totaling 45 net ft measured depth of oil pay. Identified hydrocarbon bearing intervals include 25 ft net oil pay over two intervals in Carbonera C7 and 20 ft net oil pay over four intervals in Lower Gacheta. Interval thicknesses are not necessarily indicative of long-term performance or ultimate recovery.
RCE-4 production is expected in late March 2023. The rig will then be moved to the RCE-5 location to spud within a few days of RCE-4 being brought on production. Once RCE-5 is drilled, the rig will mobilize to drill three planned wells 20 km away on the Carrizales Norte Structure.
