On 26 July 2019, Indonesian Ministry of Energy and Mineral Resources (MEMR) offered the East Gebang exploration block, located offshore in the North Sumatra Basin, under the Conventional Oil and Gas Bidding Third Round 2019. Access to bid documents is scheduled from 26 July 2019 to 18 October 2019. Submission of participating documents is from 18 October 2019 to 25 October 2019 at 2.30 pm (Western Indonesian Time).    The data package for the East Gebang block comprises approximately 9,013 km of 2D seismic data (vintage from 1968 to 2012), 471 sq km of 3D seismic data (2007), three G&G reports and three G&G maps. As an incentive to participate to the bidding exercise, free access to the data package will be granted to all companies that purchase the bid document for the related block. The data package will be only charged to the eventual winner of the block.    The minimum signature bonus for the block will be USD 2.5 million. Minimum firm commitments for the first three-year exploration period include G&G studies, 400 sq km of 3D seismic acquisition and processing. The contract will require a mandatory relinquishment of 20% of the block area at the end of the third year.    The block, covering an area of approximately 4,214 sq km, is located offshore North Sumatra, at water depths of less than 100 m. There are 11 wells previously drilled within the block area. North Sumatra Oil drilled five exploration wells in the 1970s, including three new-field wildcats (NSO 1N, NSO 1S, NSO 4N) and two outposts (NSO 3S, NSO 4S), under the Malacca Strait PSC. Aquitaine took over operatorship of the block in 1978 and drilled Pusung 1. NSO 1S was drilled to a total depth of 2,020 m and was a gas and condensate discovery, while the remaining five wells were either dry holes or gas shows.    In 1985, Chevron drilled Glagah 1 under the Langsa PSC. The well was plugged and abandoned as a gas and condensate discovery. Bow Valley Exploration drilled three wildcats under the Asahan PSC from 1985 to 1986. Two of the wells (Kemiri 1 and Kerinci 1) were unsuccessful while the third one (Kambuna 1, 1986) was a gas and condensate discovery. The Glagah and Kambuna discoveries are excluded from the East Gebang bidding block.  In 1988, Petroz drilled wildcat Tonjol 1 under the Asahan PSC, encountering minor gas indications in the Belumai Formation. In 2001, Matrix Oil drilled wildcat Kambuna West 1 (Offshore Asahan PSC), which was plugged and abandoned with gas shows. Petronas Carigali drilled exploration wells Tanjung Perling 1 (2012, gas shows), and Pakol South 1 (2014, dry) under the West Glagah Kambuna PSC.    Proven reservoir in the block area are the Belumai Formation, Baong Formation, Keutapang Formation and the Peutu carbonates. Pre-tertiary Basement is also proven to be a reservoir, with the discovery in Glagah 1 well. Several prospects and leads have been identified in the area with total recoverable unrisked resources estimated at 10 MMSTB and 488 Bcfg.  Background Information    West Glagah Kambuna PSC    The West Glagah Kambuna block covers an area of 3,244sq km. It was officially awarded to Petronas Carigali and PT Pertamina on 30 November 2009, under the regular tender mechanism for the Phase II 2008 Tender Round, with 60-40 partnership interest. Firm commitments for the first three years of exploration include G&G studies (USD 2.0 million), acquisition of 500 km 2D seismic data (USD 0.5 million), acquisition of 350sq km 3D seismic data (USD 10 million) and drilling of two exploration wells (USD 23 million). The firm seismic acquisition commitments have been fulfilled. A signature bonus of US$ 8.0 million was paid for the block.    Throughout the exploration period, Petronas Carigali drilled two exploration wildcats, Tanjung Perling 1- spudded in August 2012 and completed as a gas shows well in September 2012. The second well Pakol South 1- spudded in December 2013 and completed as dry well in January 2014.  Petronas Carigali completed a 370 sq. km 3D seismic survey from November to late December 2010 using the âGeo Natunaâ survey vessel. And in between March to April 2012, the company shot additional 800 km of 2D seismic using the Nordic Maritime âNordic Energyâ Vessel. These seismic data were used to evaluate and mature exploration prospect in the block.    The operator has filed a relinquishment request for the PSC in November 2015. Exploration commitments for the PSC have likely been completed.
