Kinetiko Energy Ltd resumes drilling at Korhaan Project in South Africa

Logging for Korhaan 3, 4 and 5 wells is to be carried out in January while the planned flow test on Korhaaan-4 will commence. 

Kinetiko Energy Ltd (ASX:KKO) has resumed drilling development activities at its Korhaan Project in South Africa after drill rigs B21 and B16, together with operational crews, returned to site. 

Logging for Korhaan 3, 4 and 5 wells is to be carried out in January while the planned flow test on Korhaaan-4 will commence.

Multi-day well testing has been planned to ensure accurate data for updated resource reporting.

The aeromagnetic survey data acquisition has been completed with interpretation underway.

Well Korhaan-4

Having successfully completed the drilling of the production section from 130 metres to 443 metres, significant preliminary gas flows were established under choked conditions.

A suite of logging tools (including gamma ray, neutron, density and optical televiewer) will be run to establish stratigraphy, locations of water and gas ingress and coal seams.

It is expected that the well-testing will be performed over a period of at least one week to enable time to establish pressure and flow stability in low-perm conditions.

From the strength of the flow rate results and groundwater fractures identified, plans will then be made to conduct a more sophisticated completion solution involving the casing and perforation of only the gassy zones which is expected to further increase flow rates and minimise or negate water ingress.

Well Korhaan-5

Drill Rig B16 will proceed to drill out the cement plug/float shoe and continue straight into the production section to terminal depth.

Similarly to Korhaan-4, the well test on Korhaan-5 will be undertaken by running a pump into the well to pull down the water and allow the maximum comingled gas flow.

The well-testing is expected to be performed over at least one week to enable time to establish pressure stability in low-perm conditions.

Well Korhaan-3

Once Rig B21 is done with the cleanout and stand by for logging on Korhaan 4, it will move over to well Korhaan-3 and run a cleanout to the current depth of 102 metres before completing the surface section to around 130-150 metres.

The surface section will then be cased and cemented and a CBL (Cement Bond Log) and verticality check run will be performed.

Once the cement has cured and logs are run, the plug and shoe will be drilled out and the well will be progressed by drilling to production target depth using air/percussion and not rotary mud, as originally planned, largely as a result of the penetration rate using air has been good, and for well control purposes, adequate kill weight mud products will be on standby.

Next phase completions

Results of the barefoot testing will provide a benchmark against which to measure the results of a post-perforation flow test.

The clear benefit of perforated completions is the management of water ingress and the consequent mitigation of downhole-choked gas flow.

Aeromagnetic results

After completing the data acquisition over three discrete survey areas in blocks ER270 and ER272, basic data has been received, as well as the Reduced To Pole (RTP) information, and geophysical interpretation is underway.

The reporting is expected to increase the company’s asset-wide compartmental count and a substantial uptick in the amount of recommended well locations.
