Reserve Update


Reserves Statement for the South Yelemes Fields' Post Salt Reservoirs, BNG Ltd LLP, Western Kazakhstan


Roxi, the Central Asian oil and gas company with a focus on Kazakhstan, is pleased to  update the market with news of a reserves update as at 31 December 2015 of BNG's South Yelemes fields. The reserves update covers the Company's shallow fields at its BNG asset and does not include its deeper prospects that are subject to drilling at its wells A5, A6 and 801.

Reserves update


Gaffney, Cline & Associates ("GCA") has conducted an independent audit examination, as of 31 December, 2015, of the crude oil reserves of BNG's South Yelemes fields. On the basis of technical and other information made available to GCA concerning this property unit, GCA has provided the reserves statement in Table 1.


The South Yelemes fields consist of two independent hydrocarbon accumulations (southeast and northwest). The fields are currently in a pilot stage of production (post salt reservoirs only) and appraisal testing and are currently producing around 600 - 800 bopd.


Roxi has confirmed to GCA that the current obligations under the assessment licence have been fulfilled (due to expire in 2018) and a full 25-year production licence is expected to be awarded, running till 2043.


The reserve numbers provided below are predicated on the progression of the company's infill drilling programme.

1.   Gross Field Reserves are 100% of the volumes estimated to be commercially recoverable from the field.

2.   Net Entitlement Reserves are the Company's net economic entitlement

3.   The Operator of the South Yelemes fields is BNG Energy LLP


Hydrocarbon liquid volumes represent crude oil, estimated to be recovered during field separation and are reported in millions of barrels in Table 1.


The BNG Licence Area (Block) is located in Western Kazakhstan 40 kilometres southeast of Tengiz on the edge of the Mangistau Oblast.


The Licence Area surrounds two smaller areas that are not included in the geological allotment as they contain the West Yelemes, Tolkyn and Saztobe Fields, operated by third parties. The BNG Licence Area, with these exclusions, amounts to 1,561 km2 of which 1,376 km2 has 3D seismic coverage acquired in 2009 and 2010.


GCA performed a detailed audit of the data and assumption presented by Roxi and considers them reasonable for the estimation of reserves; this included reservoir depth structure maps, log data, core analysis, well tests, pilot production data and cash flow models.


Reserves Assessment


The GCA audit examination was based on reserves estimates and other information provided by Roxi to GCA, and included such tests, procedures and adjustments as were considered necessary. All questions that arose during the audit process were resolved to GCA's satisfaction.


The economic tests for the reserves volumes were based on the following assumptions:


•          Export Oil Price: based on the Brent crude oil price forecast shown in the table below and further applying a discount of 10% for the differential in quality. In addition to the transportation costs (assumed as a part of operating costs), an additional tariff of US$5/Tonne (US$0.67/barrel) is applied to the export oil price.




Brent Crude Price US$ per barrel




















·          Domestic Oil Price: assumed to be US$48.7/Tonne (US$6.5/barrel) for the year 2016 and thereafter is calculated by dividing the export price by a factor of 6.6.


·          Future capital costs were derived from development plans prepared by Roxi for the field. Recent historical operating expense data were used as the basis for operating cost projections. No impact of inflation has been assumed on the future costs. GCA has found that Roxi has projected sufficient capital investments and operating expenses to economically produce the projected volumes.


It is GCA's opinion that the estimates of reserves at 31st December, 2015 are, in the aggregate, reasonable and the reserves categorization is appropriate and consistent with the definitions for reserves in the Petroleum Resources Management System (PRMS), which was approved by the Society of Petroleum Engineers, the World Petroleum Council, the American Association of Petroleum Geologists and the Society of Petroleum Evaluation Engineers in March 2007.


GCA concludes that the methodologies employed by Roxi in the derivation of the reserves estimates are appropriate, and that the quality of the data relied upon and the depth and thoroughness of the reserves estimation process is adequate.


A Copy of the GCA report will shortly be available on the Company's website at



Clive Carver, Executive Chairman said


"We are naturally delighted with the reserve update.  We believe the results strongly indicate the current value of the Company is largely covered by just the reserves from the shallow wells drilled at South Yelemes.


We look forward to adding to these reserves with additional drilling at the shallow fields of South Yelemes and most importantly from our deep wells in the Ayrshagyl region.


These reserve numbers reinforce our belief that the BNG field has enormous potential, which we continue to work to exploit in the run up to licence renewal in June 2018. With the sharp decline in the costs of drilling and with revenue from our producing wells at domestic prices currently approaching $10 per barrel- significantly ahead of the price used in the economic model, Roxi is ideally placed to develop the BNG field to its full potential.

Reserves are those quantities of petroleum anticipated to be commercially recoverable by application of development projects to known accumulations from a given date forward under defined conditions


Proved Reserves

Proved Reserves are those quantities of petroleum, which by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be commercially recoverable, from a given date forward, from known reservoirs and under defined economic conditions, operating methods, and government regulations


Probable Reserves

Probable Reserves are those additional reserves which analysis of geoscience and engineering data indicate are less likely to be recovered than Proved Reserves but more certain to be recovered than Possible Reserves


Possible Reserves

Possible Reserves are those additional reserves which analysis of geoscience and engineering data include are less likely to be recoverable than Probable Reserves
