Leyshon Resources encounters multiple pay zones in second well on the Zijinshan Gas Project

Jan 09, 2013 12:00 AM

Leyshon Resources has announced that its wholly owned subsidiary Pacific Asia Petroleum Limited (PAPL) has completed the drilling and wire line logging of well ZJS6, the Company’s second well on its Zijinshan Gas Project on the eastern fringe of the prolific Ordos Gas Basin in Central China. The analysis of the logs and the samples is ongoing, however positive initial results have indicated that about 80 metres of cumulative potential pay interval has been intersected across 15 potential pay zones. A production casing string has been installed which will provide multiple opportunities to conduct flow tests on selected potential pay zones.

ZJS6 is located seven kilometres from ZJS5 and close to the southern boundary of the 708 km2 Zijinshan Production Sharing Contract (PSC). Wells ZJS5 and ZJS6 are part of an initial three well programme designed to explore and test the potential for commercial gas production in an unexplored 380 km2 central depression area that appears to show good continuity with the neighbouring Sanjiaobei discovery.

ZJS6 was drilled, without safety incident, in 25 days to total a depth of 2,105 metres making up much of the time lost due to an unscheduled rig change, which caused the delayed spud date. Target formations were intersected at shallower depths than predicted and as a result the total depth was less than the design 2,320 metres. Wire line logging and the collection of 57 side wall core samples was undertaken by China Oilfield Services Limited. In consultation with the PSC partner, PetroChina, one of China’s major oil and gas companies, and the Company’s technical advisor, RISC, analysis of the side wall core samples and other information will be used to select which of the zones in each of the wells ZJS5 and ZJS6 will be frack tested and if warranted, flow tested. The purpose of these tests, which are expected to commence in mid-March and continue until late April or early May, is to determine whether commercial flow rates can be established from one or more potential pay zones in each well.

As in the case of ZJS5 some intervals may be tested for flow without stimulation ie: without fracking. Whilst it is obviously beneficial for zones to flow initially without stimulation it is expected that eventually all zones will require some stimulation over the course of their production life. Fracking crews will be mobilized following the two week Spring Festival Holiday (Chinese New Year) and testing will commence once weather conditions allow. Significant results will be reported as they come to hand, however, depending on whether flows are achieved and if so whether long term flow testing is required, it is possible that the overall results will not be available until June.

Planning has significantly advanced for the 2013 exploration programme, scheduled to commence in mid-February. This will initially focus on identifying the optimum location for the Company’s third well, through the acquisition of further seismic data and from information from the first two wells. The 2013 programme is also expected to include a number of wells in addition to the current three well programme. It should be noted however that drilling of these additional wells will be dependent on favorable results from the current testing and seismic programmes. Full details of the 2013 programme will be released once it is finalized and approved, expected to be by the end of January 2013. All three wells in the current programme are ideally located within approx. 10 kms of a tie-in point on the recently commissioned Lin-Lin pipeline which supplies the growing demand in Shanxi Province where well head contracts have recently been struck in the US$ 6 - 7.5 per mscf range.

PAPL is the operator of the PSC and has a 100% interest during the exploration stage. PetroChina has the right to buy back a 40% interest at the development stage. The Company has a strong cash position with US$ 47 million (A$ 45 million) in cash and 249 million ordinary shares on issue (approx. US$ 19 cents, A$18 cents and 12 pence, respectively, per share). It has a further 17 million shares available to be purchased in the current on-market share buy-back up to September 2013. The cash position does not take into account interest due nor all the liabilities for the first two wells.


Market Research

The International Affairs Institute (IAI) and OCP Policy Center recently launched a new book: The Future of Natural Gas. Markets and Geopolitics.


The book is an in-depth analysis of some of the fastest moving gas markets, attempting to define the trends of a resource that will have a decisive role in shaping the global economy and modelling the geopolitical dynamics in the next decades.

Some of the top scholars in the energy sector have contributed to this volume such as Gonzalo Escribano, Director Energy and Climate Change Programme, Elcano Royal Institute, Madrid, Coby van der Linde, Director Clingendael International Energy Programme, The Hague and Houda Ben Jannet Allal, General Director Observatoire Méditerranéen de l’Energie (OME), Paris.
