Petroceltic, Sonatrach and Enel to develop Algeria Isarene gas field

Petroceltic to prepare FEED on Ain Tsila development

2B1st_Project_Smart_Explorer_Sales_Pursuit_ToolThe Irish junior company Petroceltic International plc (Petroceltic) and its partners, the Algerian national oil company (NOC) Sonatrach and the Italian utility Enel, are preparing to move into the front end engineering and design (FEED) phase of the Ain Tsila discovery within the Isarene gas and condensate field in the center east of Algeria.

Based in Dublin, Petroceltic has a strong focus on Algerian resources as one of the key supplier of Europe in Gas.

Petroceltic signed the Isarene production sharing contract (PSC) in 2004 and proceeded with the first exploration phase of the Isarene area until August 2012.

Petroceltic_Ain-Tisla_Central-Processing-Facility_Algeria_MapAfter the Ain Tsila discovery, Petroceltic and its partners Sonatrach and Enel could post their Declaration  of Commerciality (DOC) and obtain the approval from the Algerian Authorities for the corresponding development plan in December 2012.

In line with the Isarene PSC, the full field development plan has been registered for a 30 years period in beginning with the Ain Tsila project.

Over the years there were some changes in the ownership of the Isarene PSC with Petroceltic farm-out agreements to Sonatrach and Enel in 2012.

As a result the actual situation of Isarene field working interests stand as following:

 – Petroceltic 38.25% is the operator

 – Sonatrach 43.375%

 – Enel 18.375%

Located in the liquids-rich Illizi Basin, the Ain Tsila discovery is estimated to hold 304 million barrels of oil equivalent (boe) of proven and probable reserves (2P).

Petroceltic Ain Tisla CPF to be similar to BHP Ohanet

From the 2P reserves and along the 30 years of the Isarene PSC, Petroceltic and its partners are planning to extract:

 – 2.2 trillion cubic feet (tcf) of gas

 – 70 million barrels of condensate

 – 113 million barrels of liquid petroleum gas (LPG)

To do so, Petroceltic development program for the Ain Tisla project is to maintain the plateau production during 14 years at 355 million cubic feet per day (cf/d) of wet gas.

In that perspective the Ain Tsila project includes:

Petroceltic_Ain-Tisla_Central-Processing-Facility_Algeria – 124 vertical wells

 – Gas central processing facility (CPF)

 – Water separation

 – Condensate and LPG recovery units

 – Gas compression unit

 – Export pumps

 – 100 kilometers export pipeline to the Tin Fouye Tabankort (TFT) field for connection into the Algeria Gas Transmission System.

The Ain Tsila project feasibility study was completed in 2012 but the In Amenas attack, less than 100 kilometers away, had slowed down the development program.

 So the FEED work for the Ain Tsila project originally planned in 2013 should start in 2014.

After a first series of 18 vertical wells, Petroceltic and its partners, are planning to cadence 12 new wells per year.

From the first phase the Ain Tsila central processing facility should be very similar to the BHP Billiton Ohanet project with a single train of 355 million cf/d capacity of wet gas.

In awarding the FEED contract in 2014, Petroceltic and its partners Sonatrach and Enel are expecting to sanction the Ain Tsila engineering, procurement and construction (EPC) contract in 2015 for the first production to start in 2017.
