Testing Starts on Karoon’s Boreas-1 Well (Australia)

Testing Starts on Karoon's Boreas-1 Well (Australia)

Testing of Karoon Gas Australia Ltd’s Boreas-1 exploration well in the Browse basin has commenced. During the initial well clean up a maximum flow rate of 30.2 Mmscf/d was attained through a 40/64 choke, with a flowing wellhead pressure of 3300 psia. The flow rate was constrained by current surface equipment.

The test is assessing flow rates in a perforated interval of 70 metres between 4904-4974 metres below rotary table, in the primary Plover formation reservoir. The production test will continue for approximately five days and will include shut-in and flowing periods, surface and down hole sampling of reservoir fluids and production logging. The primary purpose of the test is to assess the overall deliverability of the primary reservoir underpinning the Greater Poseidon Trend. These initial test flows are encouraging for the remaining test program at Boreas-1.

The Transocean Legend semi-submersible rig is drilling and testing the Boreas-1 well.

ConocoPhillips is the operator of the jointly held WA-314-P, WA-315-P and WA-398-P Browse Basin permits containing the previously announced Poseidon and Kronos gas discoveries. Karoon Gas Australia Ltd holds 40% of the permit WA-315-P and WA-398-P, and 90% of permit WA-314-P.

Boreas-1 is located approximately 4 kilometres south of Poseidon-1 in WA-315-P on a large tilted fault block which is part of the of the north-east trending structural high of the greater Poseidon structure. The objective of the well is to test the extent, presence and quality of reservoirs within the Boreas-1 fault block.

Future Plan

Well data from Boreas-1 will be integrated into the existing data recovered from Poseidon-1, Poseidon-2, and Kronos-1 along with the Poseidon 3D seismic data to further define the size and composition of the Greater Poseidon Trend.

The next two wells to be drilled are Zephyros-1 then Proteus-1. Zephyros-1 will test the flank of a fault block 9km west of the Kronos-1 well. Proteus-1, 15km east of Zephyros-1 will test a fault block on the eastern flank of the Greater Poseidon Trend.

The Boreas-1 well is the first of the Phase-2 drilling program, comprising five firm plus three optional wells and is designed to explore and appraise the gas resources of the Greater Poseidon Trend. Karoon’s assessment of the Contingent Resource will be independently assessed when sufficient well results have been acquired and a full analysis is conducted after the drilling program is complete.

This will allow a decision to be made regarding the most appropriate development option to be pursued.

UTC 2017

The subsea industry has, as all other parts of the oil & gas industry, been seriously rattled by the most severe downturn in the hydrocarbon energy era. However, the realization of what hit us and actions to be taken to sustain a healthy and profitable future is still on-going – unfortunately with thousands of colleagues paying the price by losing their job as one of the most severe consequences. At this time, there are signs that we have reached bottom in terms of most industry indicators, but few experts expect a sharp recovery. Many seem to believe that a slow recovery is what the industry needs in order to avoid an unsustainable capacity build-up, as seen in the period after the financial crisis. Considering the uncertainty of what the future will bring, this year’s UTC Program Committee have decided to challenge all of us to present ideas, experiences, technological innovations, business models and execution models for how to shape our subsea future and explain how and why subsea is the future.
UTC welcomes abstracts based on the topics listed below. If selected, please consider writing a paper in addition to the UTC presentation. From 2017, UTC papers will be published in an international database.
