Roxi Petroleum announces BNG operations update

Published by
Oilfield Technology,

Roxi has updated the market with news of Deep Well A6 and Shallow well 142.


Roxi has a 58.41% interest in the BNG Contract Area, which is located in the west of Kazakhstan 40 km southeast of Tengiz on the edge of the Mangistau Oblast, covering an area of 1561 square km2 of which 1376 km2 has 3D seismic coverage acquired in 2009 and 2010.

In January 2016, Roxi announced that the area of the Contract Area was extended with the addition of 140.6 km2 to the north-east of the current block. The extended BNG Contract Area now covers 1702 km2.

The block has both shallow and deep areas of interest.

Deep Well A6

Deep Well A6 was spudded in November 2015, targeting the same structure as Deep Well A5 in the Middle and Lower Carboniferous, and reached a revised Total Depth of 4528 m in October 2016.

From the analysis of wireline logging, gross oil-bearing intervals totalling 127 m have been identified. These are in two intervals, the first of 72 m between depths of 4313 m and 4385 m. The second is of 55 m between depths of 4450 and 4505 m. Further analysis will be conducted to determine the portion of these intervals that are capable of producing commercial volumes of oil ( net pay ).

Roxi now plan to complete the well by cementing a 5 in. liner to the Total Depth of the well.

Following this we intend to perforate the interval between 4450 - 4505 m to allow a 90 day flow test to commence without delay.

Shallow Wells

Roxi is interested in two shallow regions of the BNG block, (1) Yelemes, which include producing wells 54 805 806 & 807 and (2) MJF structure, which include producing well 143 and now producing Well 141.

To date Roxi has drilled five shallow wells to typical depths of 2500 m. In aggregate the wells have produced up to 1100 bpd (642 bpd net to Roxi) on test and all of the wells are considered to be commercially successful.

MJF structure

Well 142

Since the company's last update on 19 October 2016, Shallow Well 142 has been spudded and drilling has reached a depth at a depth of 600 m without incident.

Well 142, is on the MJF structure some 1600 m to the north-east of Well 143. This well is being drilled on a turn-key basis for US$1.25 million to a Total Depth of 2500 m.

The principal reason for drilling Wells 141 and 142 is to seek to prove the extent of the MJF structure.

Clive Carver, Executive Chairman said:

'We are naturally delighted with the news from deep Well A6. The oil-bearing intervals identified there are larger than those previously identified at Deep Wells A5, which is believed to be in the same structure, and at Deep Well 801.'

'We now plan to move to the all important 90 day flow test without delay.'
