(Alliance News) - The following is a round-up of earnings and trading updates by London-listed companies, issued on Thursday and not separately reported by Alliance News:

Arrow Exploration Corp - oil and gas company with projects in Colombia and Canada - Completes Rio Cravo Este-6 well in the Carbonera C7 formation in the Tapir block in the Llanos basin of Colombia. Says the well penetrated a 16-foot pay zone in a high quality upper Carbonera C7 sand, with a porosity of 27%. Says that drilling has continued at the well, with testing at Ubaque zone showed production rate of 393 barrels of oil per day. Chief Executive Officer Marshall Abbott says: "The RCE-6 test results in both the Ubaque formation and Carbonera are material and exciting for the company. The results demonstrate that the Carbonera remains a solid high volume producer while the Ubaque formation has proven production that extends beyond the Carrizales Norte complex. Multiple development locations are anticipated based on current results, including horizontal drilling in the Ubaque reservoir in the Carrizales Norte field. Horizontal wells typically produce at higher rates, increasing recovery and the economics of heavy oil fields."
