Range Resources: Trinidad operational update

Range's CEO, Yan Liu commented:

"We are very pleased with the production results from the latest well which is one of the best producing wells drilled by Range in recent years in Trinidad.

We are also continuing our focus on production growth from the ongoing waterflood programme and seeing a steady increase in oil production from this programme. With approximately half of our total production currently attributed to Beach Marcelle, we are excited by both the waterflood and development opportunities of the field and are planning to exploit its full potential as part of the upcoming work programme."

Development drilling

Range is pleased to advise that the GY 684 development well located at the Beach Marcelle field which was drilled to a total depth of 4300 ft in December 2017 has been successfully brought into production and is flowing at a stabilised rate of 120 bpd on a restricted choke of 5/32 in.

The Company is very encouraged by the results from the two wells drilled at the Beach Marcelle field in the last 12 months. The Lower Gros Morne Sands in these wells appear to be better developed than anticipated. The Company continues to study the field to further exploit and develop the Lower Gros Morne reservoir and is evaluating further drilling locations as part of its upcoming work programme.

Waterflood update

Range's focus in Trinidad continues to be on the production growth from its waterflood programme, with over 70% of total reserves attributed to these projects - approximately 11 million bbls of 2P reserves.

Production from the waterflood programme has been increasing over the last months, with 40% of current production now attributed to waterflood. The growth in waterflood production has offset the decline in primary production at the Morne Diablo field. Two of the Company's waterflood projects are currently in production: the South East area of Beach Marcelle field, and the Morne Diablo field.

Since commencement of water injection at the South East area of the Beach Marcelle field 18 months ago, production from the field from waterflooding has increased by approximately 200 bopd. The Company is currently injecting water from the existing water source wells. The total water injection into the area to date exceeds over 400 000 bbls of water.

To increase the water injection rate further, the Company has completed the construction of a pipeline to connect to additional water supply from Petrotrin's gathering station at the Beach Marcelle field. Petrotrin's water has the potential to increase the injection rate by additional 700 bwpd. Transfer of Petrotrin's water has been temporarily suspended, pending installation of a new pump.

Production from Range's second waterflood programme at the Morne Diablo field continues at an average rate of 40 bpd. The company has completed injectivity tests on other parts of the block and continues to analyse the results.

Waterflood programme expansion

The Company has been undertaking initial preparatory work (including injectivity testing) on other parts of its acreage, and is planning to expand its waterflood programme to other areas of the Beach Marcelle, South Quarry and Morne Diablo fields, with initial work expected to commence towards the end of 2018 and into 2019.

The Company is finalising its work programme plan for 2018 which will be published later this month.
