'ENSCO 107' completes drilling operations on Maari Grwoth Project

Horizon Oil (“Horizon”) is pleased to report the successful completion of the Maari Growth Project with the final well, MR10, now in production. The MR10 well has been successfully drilled and completed and, as of 6th July 2015, was flowing approximately 2,000 barrels of oil per day (“bopd”), with daily production of approximately 16,500 barrels of oil per day. The final flow rate for MR10 will be optimised by the Operator, OMV New Zealand, based on engineering data collected as the well continues to stabilise. A total of four new production wells were drilled in the Maari Growth Program using the Ensco 107 jackup rig. The operator of the Maari joint venture anticipates the field’s production capacity to increase to approximately 20,000 bopd with the optimisation of production from MR10 and an upcoming 2015 work-over campaign. The Ensco 107 is now being prepared for demobilisation from the Maari Field. The Maari joint venture’s work-over unit (“WOU”) equipment is being prepared for scheduled load out to the wellhead platform in late July 2015. The WOU will be used to carry out maintenance workovers and other activities such as adding perforations to further enhance production. The work-over campaign is scheduled will commence after the demobilisation of the Ensco 107.

OMV reports first oil from redevelopment of Maari project

OMV is pleased to announce first oil from its Maari redevelopment drilling campaign in New Zealand. The Maari redevelopment drilling campaign in New Zealand, also known as the Maari Growth project, aims to increase reserves, production and recovery from the producing Maari field. The well, known as MR-8A, was started on November 28 producing from a previously undrained compartment in the Maari field. The well was side-tracked out of an abandoned injection well and drilled horizontally into the Moki formation to a total length of 3,824 m. The production capacity for this well has been estimated at 4,500 barrels of oil per day (gross). Jaap Huijskes, OMV Executive Board member responsible for Exploration and Production: "It is a great achievement to revitalize an existing field. Conditions in the Tasman Sea are challenging and remote but the team has been able to safely deliver the project. Additional production from Maari through existing facilities will greatly improve efficiency and reduce operating cost per barrel." In April 2014, the offshore drilling rig Ensco 107 was installed in the field carrying out abandonment, workover and drilling operations. The first well was drilled into the untapped Mangahewa formation and has been suspended to implement a revised completion concept. The MR-8A well is the second in the campaign. The Maari Growth campaign includes drilling of five wells into producing and new reservoirs. Total investment of OMV will be around EUR 205 mn and the campaign is expected to be completed by mid-2015. The Maari field is located in a water depth of 100 m, around 80 km off the Taranaki coast of New Zealand. The field was developed by OMV New Zealand as operator of the Maari Joint Venture (JV) and began production in February 2009. The field production has since declined from peak rates of approx. 25,000 barrels of oil equivalent per day (net to OMV).

'ENSCO 107' jackup enroute to Maari/Manaia fields

OMV New Zealand, on behalf of its Maari JV partners, is pleased to announce the jack-up drilling rig 'ENSCO 107' has been unloaded from the heavy lift vessel Talisman in Admiralty Bay and is now on its way to the Maari field in the Taranaki Basin. A blessing of the rig was performed by Ngati Koata and Ngati Ruanui in Admiralty Bay prior to its floating off and journey to Maari. The tow to the Maari field will take approximately 18 hours before the rig commences the final approach to the set up position for moving alongside the Maari Wellhead Platform. “The focus of the Maari Growth project is to access untapped oil accumulations in the permit and to better drain the existing reservoirs,” explained Peter Zeilinger, Managing Director of OMV New Zealand. “This should help stabilise the natural production decline we are seeing at the field and allow us to continue production at Maari for at least another 10 years.” The drilling program of five wells is expected to run well into 2015 and will keep a workforce of more than 250 personnel occupied on and offshore to safely deliver the project. The ‘ENSCO 107’ is returning to familiar waters at the Maari field. It drilled the field’s original production and water injection wells as well as the Manaia-1 well which, at eight kilometres long still holds the record for the longest well drilled in New Zealand.

Vietnam Cua Lo-1 exploration well completes testing

KrisEnergy Ltd. (“KrisEnergy” or “the Company”), an independent upstream oil and gas company, announces the completion of the drilling and testing of the Cua Lo-1 exploration well in Block 105-110/04 (“Block 105”). The Cua Lo-1 well was drilled to a measured depth of 2,867 metres, or 2,837 metres total vertical depth subsea. Based on log interpretation, several gas bearing sandstone reservoirs were identified. A drill stem test was conducted on a reservoir evaluated with the largest potential within the prospect. Although gas flowed during the test, the poor reservoir deliverability rate combined with high carbon dioxide content suggests that development of the tested reservoir will be unlikely. The well will be plugged and abandoned. The Cua Lo-1 well confirms both the trapping mechanism and the existence of a petroleum system in Block 105 and provides valuable data for deciding the future exploration strategy in the block. Additional oil and gas prospectivity exists within the block, providing opportunities for further exploration. Block 105 covers an area of 7,192 sq km offshore northern Vietnam, overlying the central Song Hong Basin where water depths range from 20 metres to 80 metres. The water depth at the Cua Lo-1 location is 76 metres. KrisEnergy holds a 25% working interest in Block 105 and is partnered by Eni Vietnam B.V. as the operator with 50% working interest and Neon Energy (Song Hong) Pty Ltd with 25%.

Vietnam Ca Ngu-1 exploration well reaches total depth

KrisEnergy Ltd. (“KrisEnergy” or “the Company”), an independent upstream oil and gas company, is pleased to announce that the Ca Ngu-1 exploration well in Block 120 has reached a total depth of 1,290 metres measured depth (“MD”), or 1,267 metres total vertical depth subsea (“TVDSS”). The Ca Ngu-1 well commenced drilling on 10 October 2013. Water depth at the Ca Ngu-1 location is approximately 270 metres. Wireline log data confirmed the presence of gas in Pliocene sandstone reservoirs, and a 15.2 metre gross hydrocarbon column within the Miocene carbonate reservoir, comprising a 10.6 metre gas column above a 4.8 metre oil rim. Drilling operations have been delayed by a series of strong typhoons passing through the region, which have resulted in the evacuation of crew from the Songa Mercur semisubmersible rig on several occasions. Chris Gibson-Robinson, KrisEnergy’s Director Exploration & Production, commented: "Ca Ngu-1 is being plugged and abandoned after encountering gas and oil volumes in the primary objective. Although the Ca Ngu well did not encounter significant volumes of hydrocarbons, it has confirmed the existence of a petroleum system in the area and provides valuable data for us and our partners to analyse before deciding our future exploration strategy within Block 120. We are encouraged by the preliminary results and it is important to reiterate that Block 120 has multiple exploration plays.” Block 120 covers an area of 8,574 sq km overlying the Quang Ngai Graben and the Tri Ton Horst where water depths range from 50 metres to 1,100 metres. The graben connects the Song Hong and Qiongdongnan basins in the north to the Phu Khanh Basin in the south. KrisEnergy holds a 25% working interest in Block 120 and is partnered by Eni Vietnam B.V. as the operator with 50% working interest and Neon Energy (Song Hong) Pty Ltd with 25%.

Vietnam Cua Lo 1 ST-1 exploration well reaches total depth

KrisEnergy Ltd. (“KrisEnergy” or “the Company”), an independent upstream oil and gas company, is pleased to announce that the Cua Lo 1 ST-1 exploration well in Block 105-110/04 (“Block 105”) has reached a total depth of 2,867 metres measured depth (“MD”), or -2,800 metres total vertical depth subsea (“TVDSS”). The operator, Eni Vietnam B.V., is currently running wireline logs prior to undertaking a drill stem test. The Company intends to make a further announcement once all data has been received and analysed. The Cua Lo 1 ST-1 well is a sidetrack well to the original Cua Lo-1 exploration well, which commenced drilling on 11 August 2013 and was then subsequently plugged back from a depth of -2,531 TVDSS and sidetracked due to an unexpected high pressure kick. Drilling operations have been further delayed by a series of strong typhoons passing through the region, which have resulted in the evacuation of crew from the Ensco 107 jack-up rig on four occasions. Block 105 covers an area of 7,192 sq km offshore northern Vietnam, overlying the central Song Hong Basin where water depths range from 20 metres to 80 metres. The water depth at the Cua Lo 1 ST-1 location is 76 metres.

Cua Lo-1 exploration well begins drilling offshore Vietnam

KrisEnergy Ltd. (“KrisEnergy” or “the Company”), an independent upstream oil and gas company, is pleased to announce that today the Ensco 107 jack-up rig began drilling the Cua Lo-1 exploration well in Block 105-110/04 (“Block 105”) in the Gulf of Tonkin, offshore Vietnam. The Cua Lo-1 exploration well is planned to reach approximately -2,800 metres total vertical depth subsea and is intended to test the Cua Lo gas prospect. It is anticipated that drilling will last approximately 42 days. “Cua Lo-1 is the first of two high impact exploration wells offshore Vietnam for us this year and we are excited to be finally drilling this attractive and large prospect. It is important to note that this is a wildcat well and therefore the risks are high, but both Block 105 and our other licence offshore Vetnam, Block 120, contain multiple prospects for future drilling whatever the outcome of these wells,” said Chris Gibson-Robinson, KrisEnergy’s Director Exploration & Production. Block 105 covers an area of 7,192 sq km in the Gulf of Tonkin, overlying the central Song Hong Basin where water depths range from 20 metres to 80 metres. The water depth at the Cua Lo-1 location is 76 metres. KrisEnergy holds a 25% working interest in Block 105 and is partnered by Eni Vietnam B.V. as the operator with 50% working interest and Neon Energy (Song Hong) Pty Ltd with 25%.
