Friday October 30, 2020 The Magneto-Telluric (MT) survey on geothermal exploration is mandatory like seismic in the oil and gas industry and MT method is mandatory in geothermal detailed survey in Indonesia. In the exploration stage (even in the development stage), geophysics is the most important surface method used to image the subsurface physical parameters associated with a geothermal system. MT imaging is the most powerful technology to define the top of reservoir, delineate the geometry of reservoir and determine well target zones. Many wells have been drilled on the basis of the MT resistivity guidance to the target zones.…

Monday October 26, 2020 Mount Tangkuban Perahu is located in West Java Province between Bandung and Subang cities, among its manifestations are including craters, fumaroles, steaming ground, silica sinter, and hydrothermal alteration. West Java is a province with the largest geothermal potential in Indonesia, which is around 5.4 GW, equivalent to 20% of the national potential. From 2.1 GW geothermal installed capacity, there are 1.2 GW which are produced in West Java from 7 fields, namely: Kamojang, Darajat, Awibengkok Salak, Wayang Windu, Patuha, and Karaha Bodas. In 2017 the government assigned PLN to manage the Tangkuban Parahu WKP and was…

Wednesday October 21, 2020 After the success of the inaugural webinar with Prof. Hochstein, NQ Academy will organize the 2nd NQ Academy Webinar with theme “MT vs Drilling: Valuable Experience from Geothermal Exploration in Indonesia”. The webinar will be scheduled on October 24th, 2020 using the zoom platform and will present a speaker, Dr. Yunus Daud (Founder of NewQuest Geotechnology). This topic is very interesting, because it will discuss experiences and lessons learned about the application of MT technology in geothermal exploration. Many geothermal fields have been drilled on the basis of MT technology guidance. MT can be used to…

Friday August 21, 2020 Geological Agency data end of 2019 showed that there were 15 geothermal locations in North Maluku province, the 15 locations are classified as 5 high temperature systems, 4 medium and 6 low. While from the survey status, 4 locations have been carried out reconnaissance surveys, 6 preliminary surveys, and 5 detailed surveys. 4 of these locations have been designated as Geothermal Working Area (WKP) namely, Songa Wayaua 42 MW – assignment WKP to PLN, WKP Gunung Hamiding 175 MW – Pre Survey & Exploration Assignment (PSPE) to Star Energy, WKP Jailolo 75 MW will be drilled…

Friday August 21, 2020 IAGI Award IAGI Award IAGI Award IAGI Award NQG Wins Indonesia Geologist Association (IAGI) Exploration Awards 2020 for “Best Geothermal Services Company” category. The IAGI Exploration Awards 2020 is the first event in Indonesia that gives awards for the achievements of the exploration of earth/ natural resources, whose process began in September 2019, culminating in 29 September 2020 by announcing the award winners. There are 5 types of awards namely; Best Exploration Investment (Largest Expenditure & Exploration Commitment), Best Discovery, Best Innovation and Technology, Best People Development and Best Service Company for each kind of resources;…

Monday September 28, 2020 In Indonesia, there are hundreds of electricity systems, from a large system 35 GW Java Bali system to a small system with size only a few MW. East Nusa Tenggara (NTT) Province has more than 60 power systems, one of which is the Lembata system with a current capacity of 5 MW and peak load of 4.1 MW. East Nusa Tenggara ( NTT ) is an archipelago province with 1,192 islands, 44 inhabited islands, 29 islands with electricity and 15 islands still not electrified. There are several islands in Indonesia that can be 100% electrified by…

Friday September 25, 2020 NQ Academy is a geothermal center of excellence under NewQuest Geotechnology that provides training courses, webinars, e-learning as well as corporate in-house courses for improving knowledge and skills in geothermal resources and technology officially introduced by its founder Dr. Yunus Daud on 23 September 2020 at the beginning of the 1st NQ Academy Webinar. In his message, Dr. Yunus emphasized that NQ Academy will collaborate and be open with anyone and any party to advance Indonesia’s geothermal industry, especially in developing human resources. The webinar present Prof. Manfred P Hochstein, Founder of Geothermal Institute, The University…

Monday September 21, 2020 NQ Academy, is a geothermal center of excellence under NewQuest Geotechnology, will held the 1st NQ Webinar on Wednesday November 23, 2020.

Wednesday August 26, 2020 Geological Mapping Gravity Survey MT Survey Sumur B1 Tulehu WKP is one of the 21 Old WKPs established since Pres.Dec (PD) No. 6/1974 PERTAMINA to develop geothermal until the 90s. PLN started managing the Tulehu WKP in 1993, exploration in early 1994. In 2009, PLN Geothermal conducted a re-study of the geothermal working area in Tulehu and decided to continue exploration in December 2010 by drilling 1 exploration well TLU-01, despite having encountered problems, the drilling results of TLU-01 confirmed the existence of high-permeability reservoir. Moreover, many data indicated that the reservoir temperature exceeds 200oC from…

Friday August 21, 2020 Crater Lake Gravity Survey MT Survey Geothermal potential according to Geological Agency of Indonesia data in December 2019 was 23.9 GW is spread over 351 locations in 30 provinces across Indonesia. Blawan-Ijen Geothermal Area ( WKP ) is located in the Banyuwangi and Bondowoso Districts in the east Java Province. WKP Ijen manage by Medco Cahaya Geothermal and Ormat Indonesia has become Indonesia’s geothermal hot spot in the last 4 years because Ijen is the first geothermal discovery for East Java province, Ijen Slim hole is the first deep slim hole flowing in Indonesia in 2016.…
