Shewashan Output Significantly Below Target

Gas Plus Khalakan (GPK), the sole contractor of the Khalakan PSC in the Kurdistan Region of Iraq, has issued an end-2017 operations update regarding the Shewashan field.

Oil Sales:

Total payments received by GPK for oil sales now amount to $9.0 million representing 190,115 barrels of GPK entitlement oil sold through to the end of September 2017. Sales from  October  to December  has  been  invoiced  through  the  traditional  operating procedures in place with the KRG Ministry of Natural Resources.

Oil Production:

In total, cumulative field production to date exceeds 1,300,000 barrels of oil. Current total field production is 1,000 barrels per day. Total oil production for the 3rd quarter 2017 was 81,207 barrels and 422,027 barrels have been produced in 2017, up to and including 1 December 2017.

These amounts are significantly below that required to meet forecast annual production targets and break-even economics. There are two main reasons for this lower production.

Firstly, water production rates in the Qamchuga formation have limited oil production rates. The Qamchuqa formation is heavily fractured and many of these fractures are connected to the aquifer.

Secondly, production rates from the Shiranish and Kometan reservoirs have been limited, due to these formations having a tight matrix, with their fracture network being not as developed and extensive as in the Qamchuqa reservoir. GPK continues to recomplete the four Shewashan wells to limit water production in the Qamchuga and stimulate the Kometan and Shiranish reservoirs to facilitate greater production rates.

This activity is summarized below:

Shewashan #1:

Current production rate: 350 bopd and <5% water cut from the Qamchuqa reservoir. Recompletion plans include: perforation and acid stimulation of the Kometan reservoir.

Shewashan #2:

Current production rate: 650 bopd and low water cut from the Kometan reservoir. Recompletion plans include:  Larger acid stimulation in the Kometan to increase the production from perforated intervals (45m) and a possible propped hydraulic frac in the Shiranish reservoir which has yet to be tried in the field.

Range Energy gives Shewashan Operations Update

Range Energy Resources has announced that Gas Plus Khalakan (GPK), the sole contractor of the Khalakan PSC in the Kurdistan Region of Iraq, issued an operations update regarding the Shewashan field.

Shewashan #4:

The 4th well drilled on the Shewashan field, Shewashan #4, has been completed as a deviated producer in the Qamchuqa reservoir formation only to first extract remaining recoverable oil from this reservoir. There are future plans to recomplete on the Kometan and Shiranish reservoirs. The well was put on production at a rate of 500 bbl/d and is connected to the early production facilities.

The well completion utilized a hydrajet targeted acid stimulation through coiled tubing to enhance production from the fracture network. This is a technique that may now be applied to the other existing wells on the Shewashan field to further enhance productivity in the Qamchuqa and Kometan reservoirs. Water production is approximately 2500 bbl/d, an amount which is well within the design parameters of the new early production facilities.

Shewashan #1:

The Shewashan #1 well has been sidetracked and a new 4.5 inch liner installed. The well has now being recompleted on the Qamchuqa reservoir formation and is producing 750 bbls/day on a 24/64” choke and is currently water free. This well did not require a hydrajet targeted acid stimulation.

Shewashan #2:

The Shewashan #2 well which was previously producing 250 bbl/d from the Shiranish reservoir, is currently being sidetracked as the water isolation program conducted in Q2 2017 has resulted in reservoir damage that cannot be repaired. Production from the well is expected to be further enhanced with the stimulation techniques once a 4.5 inch liner has been installed.
