Located five to seven miles offshore, the field came onstream in October 2005 with production initially reaching up to 50,000 barrels of oil a day. The other major contractors involved in the project were Baker Hughes, Halliburton, Schlumberger, Weatherford, Welltec Oilfield Services, Pacific Rim Constructors, SakhalinNIPImorneft, Primorsky Drill Rig Services, SakhWest Construction Kentech Sakhalin Technical Services, Remote Projects Services Group, Fircroft Engineering Services, NovusOrenStroy, Kvaerner, and Ecc-Veco. The Sakhalin-1 project is operated by Exxon Neftegas (ENL), a subsidiary of Exxon Mobil which holds a 30% participating interest. In 1997, the ExxonMobil operated Sakhalin I Consortium acquired a 3D seismic survey over Chayvo Field, located off the northeast coast of Sakhalin Island, Russia. We respect your privacy, by clicking 'Subscribe' you will receive our e-newsletter, including information on Podcasts, Webinars, event discounts, The Yastreb rig involved in Odoptu Stage 1 development was upgraded in preparation for the project. The well stream is exported to the onshore processing facility where it co-mingles with the Chayvo stream. The Chayvo field came on stream in October 2005, followed respectively by the Odoptu and Arkutun-Dagi fields in 2010 and 2015. ", 26 July 2007 (Last Updated July 26th, 2007 18:30). In the longer term, North Chayvo will deliver annual plateau production of around 1.5 million tonnes of crude oil.

Commercial oil production under the project began in late 2005, when the Chayvo field was commissioned. In early 2007 Exxon Neftegas entered the record books when it completed the extended-reach Z-11 well on the Sakhalin-1 project, drilled from Sakhalin Island off the east coast of Russia.

Notably, more than 80% of the Sakhalin-1 project drilling rig operators are Russian nationals and project contract awards to Russian companies have reached approximately $3.8bn. Insights from the world’s foremost thought leaders delivered to your inbox. Ongoing drilling has proven to be successful with actual reservoir depths within a few meters of prognosed depths at well reaches of 9-11 kilometers, underscoring the value in the integration of seismic interpretation and extended-reach well planning in a 3D visualization environment. Sakhalin-1 was a technically challenging project to develop due to the harsh arctic climatic conditions in the Northern Sakhalin region. Please enable cookies on your browser and try again.

Overall, the Chayvo field reached its peak production rate of 250,000 barrels (34,000 metric tons) a day in February 2007 after an on-schedule startup in October 2005. It also supplied 2.48 billion cubic metres (bcm) during the year. You will be redirected once the validation is complete. This appraisal well and associated sequence stratigraphic studies resulted in a significant oil project in a field previously thought to be mostly gas. Field development model involves the use of innovative drilling technology. Online Event, November 02 - 04, 2020 Using extended reach drilling (ERD), which allows the project to reduce its offshore operations by using remote reservoirs from a central area, in most cases onshore, Exxon has brought down costs, and safety and environmental concerns.

Sakhalin-1 was a technically challenging project to develop due to the harsh arctic climatic conditions in the Northern Sakhalin region. Most of the Orlan wells are in the 5.5km range, with the longest well drilled being 7.5km long.

The Sakhalin-1 project produced more than 11.63 million tonnes of oil and condensate in 2018. 11:00 AM - 11:45 AM EST, 2020-10-28 You have the right to object. 2020-11-12 Online Event. © 2020 All rights reserved. The oil and gas from the Chayvo, Odoptu and Arkutun-Dagi fields is transported through a pipeline to the Chayvo onshore processing facility. Since drilling deeper than ever before, Sakhalin has grinded its existence into the mind of the offshore industry. Online, GMT -03, November 10, 2020 The production well, referred to as O-14, was completed in 2017 by Rosneft and Exxon, beating five previous world records for deepest wells, all drilled at the same field: Chayvo… © Autonomous Nonprofit Organization “TV-Novosti”, 2005–2020. A 3D seismic survey acquired in 1997 over Chayvo Field, offshore Sakhalin Island (Figure 1), identified the potential for large oil rims in reservoirs which had tested mostly gas in crestal wells. Client Oversight Services, Surveys, Investigations, Testimony, Rig Excellence Training, Hot Work Safety Solutions for the Oil & Gas Industry, "Sakhalin-1 is effectively the longest extended-reach drilling well in the world. The tankers are loaded with oil at an elevated single point mooring facility located 5.7km east of the De-Kastri terminal. It developed a number of proprietary technologies to deliver the Z-11 well, for example, including Exxon's integrated hole quality (IHQ) technology and the fast drill process. While AutoTrak was used to orient the lower sections of the hole, followed by the AutoTrak G3.0, the top section was oriented using the GyroTrak system. Fluor Daniel Eurasia, a subsidiary of Fluor, was the engineering, procurement, and construction (EPC) contractor for the onshore processing facilities (OPF) at Chayvo. Free Online Event for In House Industry Professionals, 01 December, 2020 Interpretation of 3D seismic revealed seismic amplitude anomalies that conformed to structural spill, were down dip of gas accumulations seen in crestal wells, and indicated the potential for very large, previously unrecognized oil rims. The Kola Superdeep Borehole was allegedly shut down in 1992 because it actually reached “hell” itself. To do this, factors such as the reservoir quality, producibility and well locations had to be found. The drilling of a 15km-long well from the Orlan platform at the Chayvo field was completed in November 2017. But in 2012, Exxon Neftegas beat its own record by completing the Z-44 Chayvo well. However these fields had never been properly assessed and a reevaluation of the commercial viability had to be carried out. Chayvo was the first field to be exploited in the Sakhalin–1 project. Commercial oil production under the project began in late 2005, when the Chayvo field was commissioned. The Chayvo Yastreb land rig, launched in June 2002, was engineered and constructed especially for Sakhalin-1 and, just like the project itself its existence was no mean feat. The Odoptu Field is located 70 kilometers north of Chayvo and began production in 2010. Already an IQPC Community Member? The rims were identified from pairs of amplitude anomalies that conformed to structural contours and were interpreted as gas-oil and oil-water contacts. John Howes takes a closer look at what, from an engineering perspective, makes Sakhalin so intriguing. In this infographic from Fuel Fighter we focus on the Z-44 Chayvo Well, the deepest on the planet.SEE ALSO: FPSO revival: Opportunities and outlookIn 2011, Exxon Neftegas, operator of the Sakhalin-1 project, drilled the then world’s deepest well surpassing previous record holders the Al Shaheen well and the Kola Superdeep Borehole as the world’s longest borehole. Over the years drilling companies have had to go deeper into the earth to extract oil. This latest record comes two years after theSakhalin-1 Consortium said it had drilled the world’s longest well to date at the Chayvo field offshore Sakhalin Island. But despite the sheer size of Sakhalin-1, and the controversy around its seismic testing, Exxon Neftegas has also worked to minimise environmental impact with its infrastructure operation.
