- Range Resources [LON:RRL] was one of the sector's biggest risers in late trading after it said initial log evaluations on the MD 250 development well in Trinidad are highly encouraging with multiple hydrocarbon bearing zones identified.

These zones would now be tested to determine the well's producing potential.

The Company will commence a production testing programme by perforating and testing four sand intervals located in the lower zone of the well between 3,350 and 3,900 feet with an estimated net pay of over 40 feet.

The relevant approvals have been submitted to the regulatory bodies in Trinidad.

"Once testing on the lower zone has been completed, the Company plans to test further multiple promising intervals of the well, located in the middle and upper zone of the well between 1,350 and 2,700 feet, with an estimated net pay of over 100 feet, pending approvals from the regulatory bodies in Trinidad," the company said.

"The MD 250 well was drilled to a total depth of 4,100 feet, significantly ahead of the expected drilling schedule and was completed using a 5 1/2" casing string and cemented to surface. This is the first well to be drilled using RRDSL's (a wholly owned subsidiary of LandOcean Energy Services Co., Ltd) new 4,000 m rig."

Victoria Oil and Gas [LON:VOG] subsidiary Gaz du Cameroun (GDC) has agreed a USD26m debt facility to support its production expansion at Logbaba through 2016 and 2017.

The facility has been secured with BGFIBank Cameroon (BGFIBank). VOG aims to avoid recourse to equity markets, whilst ensuring gearing is restricted to appropriate levels as the Company continues to build value.

During 2016 VOG intends to increase gas production from the Logbaba Project by 30%, following the 107% increase in average daily production achieved in calendar year 2015.

Chariot Oil & Gas [LON:CHAR] posts a pre-tax loss of $14.7m for the year ended 31 December - down from $41.5m in 2014.

Operating losses narrowed to $12.0m from $41.4m a year ago.

Chief executive Larry Bottomley said: "The current downturn that the oil sector is experiencing is more dramatic than expected and we have had to adapt to the changes that the lower for longer oil price has brought.

"The environment has affected the whole E&P industry, however we are pleased with the company's continued robust positioning. Our portfolio fundamentals remain unchanged by these external influences and our strong cash position with no debt offers us a solid platform to be able to make progress in these tougher times.

"We continue to deliver on our strategy; partnering for drilling, managing risk and progressing the technical understanding of our asset base whilst being opportunistic yet prudent in these market conditions."

Rockhopper [LON:RKH] has booked a FY pretax loss of USD44.7m, which is materially wider than the preceding year's loss of USD7.6m. Revenue improved to USD3.97m, from USD1.91m.

The result included UD22.9m of exploration and evaluation expenses, from USD1.8m.

Chairman Pierre Jungels intends to retire after the company's AGM. He commented on the performance:

"2015 has been transformational for your Company. Through our merger with Falkland Oil & Gas we have consolidated our leading acreage and resource position in the North Falkland Basin.

"Our exploration campaign has achieved significant success with multiple oil discoveries at Zebedee and Isobel Deep.

"The potential of the Isobel-Elaine complex, in a previously underexplored part of the basin, has been materially de-risked and supports management's view that the North Falkland Basin could ultimately deliver a billion barrels of recoverable oil.

"The Sea Lion project has entered FEED - another significant milestone on the path towards project sanction.

"Going forward, we anticipate additional cost reduction opportunities being pursued during FEED to further enhance the economics of the Sea Lion project as we move towards a project sanction decision point in mid-2017.

"Premier Oil has confirmed its intention to seek an additional partner ahead of taking project sanction and Rockhopper will support Premier Oil in this initiative.

"Our Greater Mediterranean business has seen a step-change in production having achieved an exit rate for 2015 of over 700 barrels of oil equivalent per day. We will continue to pursue opportunities which add low-cost, value-accretive production to our portfolio whilst preserving our strong balance sheet."

Premier Oil [LON:PMO] has confirmed first oil from the Solan field was safely achieved on April 12.

The first producer well (P1) is being naturally flowed at a deliberately restricted initial rate.

It is planned that the well will remain free flowing for a short time after which the ESP (pump) will be turned on.

Following this initial period and, taking advantage of the availability of the Superior Flotel, over which Premier has contractual options until the end of May, Premier intends to carry out a planned production shut down to complete the final commissioning of the water injection plant, the tie in of the second water injection well (W2) and preparation for the tie in of the second producer well (P2).

The Ocean Valiant rig is currently drilling the second producer well (P2y), where 1,500ft of high quality reservoir sands have been intersected and which is expected to be completed and tied-in by mid-year.

Production from the field is expected to build up to an anticipated production rate of 20-25 kbeopd in the second half of 2016 when both pairs of producer-injector wells will be on stream.

Lansdowne Oil & Gas [LON:LOGP] has announced that, through its 20% interest in the Barryroe Field, it will need to raise capital to meet any liabilities arising from the court ruling in respect of the Providence Resources (PVR)-Transocean litigation and for its on-going working capital requirements.

As a result, the Company has requested the continued suspension of its shares from trading on AIM pending clarification of the Company's financial position.

In the meantime, the Company said it is in active discussions with its financial advisors and current debt provider with the objective of ensuring that the Company has the appropriate financial resources to satisfy its obligations under the Barryroe Joint Venture Agreement and meet its on-going working capital requirements.

Providence Resources [LON:PVR] has announced that, in respect of the litigation between the Company and Transocean Drilling, a judgment has been handed down today by the Court of Appeal granting Transocean's appeal on the set off point.

All other aspects of Mr Justice Popplewell's judgment remain in force, including the finding that Transocean was in breach of contract.

Providence estimates the financial implications of the Court of Appeal's judgment will result in the payment of approximately USD7 million (excluding interest and costs) to Transocean.

The parties and their legal advisors are currently in the process of agreeing the final amount payable to Transocean.

The Company provided the following background information:

The case relates to certain costs claimed by Transocean against Providence regarding the use of the semi-submersible drilling unit, the Arctic III, in 2011/12 on Providence's Barryroe oilfield, offshore Ireland. The total claim, which was made by Transocean in 2012, amounted to approximately USD19 million.

Providence, in defence of its position, counterclaimed against Transocean.

The Hon. Mr Justice Popplewell, in his judgment of 19 December 2014 in the Commercial Court in London, found that Transocean was in breach of contract for failing to maintain various parts of its sub-sea equipment and that Transocean was not, therefore, entitled to certain amounts reflecting Transocean's own day rate remuneration.

As previously disclosed, Transocean sought and was granted the right to appeal one aspect of Mr Justice Popplewell's judgment, which specifically related to whether Providence was entitled to set off certain spread costs against Transocean's claim.

The appeal of this aspect of the judgment turned on the Court of Appeal's interpretation of the wording of the consequential loss clause in the rig contract (Mr. Justice Popplewell had found that Providence was entitled to set off certain spread costs). The appeal was heard in March 2016.

On 12 November 2015, the Company announced that it had re-negotiated the terms of the Option Agreement and all payments due in 2015 had been deferred until 2016 with a payment of USD385,000 due in March 2016, followed by a further nine monthly instalments of USD385,000, totalling USD3.85 million, with the last payment to be made in December 2016.
