Last year a group of petroleum engineering students at Imperial College, London, came up with an ambitious idea--a field trip to China. We were curious to see, understand, and appreciate how a different culture and economy has succeeded to become a competitive and modern country. Our choice was quite logical given the fact that China is also one of the major players in the world oil and gas industry. We decided to meet petroleum engineering students at China Petroleum U. and visit Shengli oil field, the second largest onshore oil field in China and operated by Sinopec. Needless to say, there was a huge financial and logistical challenge in organizing the trip.
The Russian independent will likely sell an ownership stake to an additional partner in the coming weeks, joining Total, CNOOC, and CNPC. FID is expected to take place later this year. The 15-year deal calls for 1 million tons of LNG to be shipped each year to the Iberian Peninsula. Final investment decision on the project is expected in the second half of 2019, with the first liquefaction train scheduled to start up in 2023.

DNV GL’s Rig Spray JIP aims to help operators working in the Arctic better predict the potential for sea spray icing on offshore structures, which poses a significant safety hazard. Cost and delivery of long-distance natural gas pipelines to a distant liquefaction facility at a warm-water port has become excessive, and environmental restraints have been increasing. An alternative is an offshore ice-resistant LNG port accommodating a new class of LNG transport vessels.
The launch will make Shenzhen Gas the second Chinese city gas distributor backed by a local government to own an LNG import facility, following Shenergy Group’s Shanghai import terminal. Eni is set to deliver an initial cargo to the facility. ADNOC and CNOOC will explore multiple new opportunities for collaboration across the upstream and downstream sectors in the UAE and China. Louisiana state granted a tax incentive to LNG Ltd. for its Magnolia project in Lake Charles. The escalation of the trade war between the US and China could jeopardize several LNG megaprojects that are awaiting final approval.
Africa (Sub-Sahara) Drilling began on the Bamboo-1 well, located around 35 miles offshore Cameroon in the Ntem concession. The Bamboo prospect is a basin floor fan target within an Upper Cretaceous play. The well will be drilled to an estimated depth of 4200 m. Murphy Cameroon (50%) is the operator, with partner Sterling (50%). The Nene Marine 3 exploration well--located in the Marine XII block, which is around 17 km offshore Congo--encountered a wet gas and light oil accumulation in a presalt clastic sequence Eni (65%) operates the Marine XII block, with partners New Age (25%) and Société Nationale des Pétroles du Congo (10%). CNPC said PetroChina is now building a production facility capable of pumping 4 Bcm/yr.
Chinese city gas distributor Shenzhen Gas will launch its first full-owned terminal to import LNG, according to a Reuters report. This will make Shenzhen Gas the second city gas distributor backed by a local government to own an LNG import facility. Shenergy Group was the first such distributor to do so, opening an LNG import terminal in Shanghai in 2008. Located at the Yantian port in the city of Shenzhen, approximately 6 miles from the larger CNOOC-operated Dapeng LNG terminal, the facility includes a new LNG berth and an 80,000-m3 storage tank. Qiu Lihua, general manager of Shenzhen Gas subsidiary (and terminal operator) Sino-Benny, said the new facility will have an annual capacity of 800,000 tonnes of LNG.

JZS is an offshore metamorphic rock buried hill oilfield. Both horizontal and vertical velocities of the oil field change very fast. The interval velocity of the buried hill stratum is twice that of the overlying strata, and the top surface of the buried hill fluctuates greatly with a maximum height difference of 300m. In the complex buried hill reservoir, since the current professional seismic software can not realize variable time-depth relationship in horizontal direction, which leads to the error of the trajectory form and position of the horizontal well in time domain, therefore the well trajectory in time domain is not matched with that in depth.
In this paper, a new practical trajectories matching method for buried hill horizontal wells in time domain and in depth is presented. First of all, we carried on the research on the theoretical form of horizontal well trajectory in buried hill in time domain. The research shows that the theoretical trajectory form of a horizontal well in buried hill is consistent with trend of the buried hill top surface morphology. On the basis of theoretical research, by establishing the pseudo time-depth relationship of horizontal well based on measure depth (MD) and seismic reflection two way time (TWT), we realized the accurate characterization of the trajectory form and position of a horizontal well in buried hill in time domain: (1)For normal horizontal well with no more than 90 degrees inclination angle, we can respectively establish the pseudo time-depth relationship of the horizontal well in buried hill segment and in upper segment, and then merge both time-depth relationship data into a whole; (2)For the complex horizontal well with well segment whose inclination angle is more than 90 degrees, we need firstly split the well trajectory into normal well segment and complex segment according to inclination angle, then establish the pseudo time-depth relationship in normal and complex well segments respectively. More specifically, we can split the trajectory into normal trajectory segment with the inclination angle no more than 90 degrees and complex trajectory segment with the inclination angle more than 90 degrees, for normal segment, we can establish pseudo time-depth relationship like the normal horizontal well described earlier, for complex trajectory segment, we need creatively invert the top and bottom of the complex segment to convert inclination angle of the segment to within 90 degrees, and then establish pseudo time-depth relationship of the inverted segment.
Through this method, we can obtain the accurate trajectory form and position of the horizontal well in time domain and it provides a basis for accurate geological modeling based on 3D seismic attributes constrains. The real reservoir performance of JZS buried oilfield in Bohai Bay in China has proved that the 3D geological model based on the new time-depth relationship (MD&TWT) of the horizontal wells is closer to the actual reservoir.
The International Petroleum Technology Conference (IPTC) will be held from 26-28 March 2019 in Beijing, China at the Beijing International Convention Center. Returning to Beijing for the second time, this 11th edition of IPTC is hosted by China National Petroleum Corporation (CNPC) and co-hosted by Saudi Aramco.
According to the latest annual survey from industry technical advisor DNV-GL, digitalization is a strong No. 1 in the top ten research and development (R&D) priorities for oil and gas investments in 2019, and challenges have shifted from barriers of adoption to those related to increasing adoption. Forty-five percent of survey respondents said they would invest in digitalization this year—more than twice the 21% who said they would invest in the second-ranked priority, subsea technology. Thirty-six percent of senior oil and gas professionals and 60% of total respondents said they plan to increase investment this year, from R&D to full-scale implementation. The prevailing sentiment is that digitalization is crucial to providing the long-term efficiency and productivity gains the industry needs to maintain its competitiveness over the declining cost of renewable energy over the coming decades. Value Creation A 2017 report by the World Economic Forum says digitalization has the potential to create approximately $1.6 trillion of value for oil and gas firms.
Mozambique LNG1, a sales entity jointly owned by co-venturers in the Mozambique Offshore Area 1, has signed a sale and purchase agreement with CNOOC Gas and Power Singapore. Area 1 operator Anadarko said the agreement covers a supply of 1.5 mtpa over a 13-year term. Mozambique LNG will be the country’s first onshore LNG development. The facility will be equipped with two LNG trains with a total nameplate capacity of 12.88 mtpa to support the development of the Golfinho/Atum fields, which are located entirely within Offshore Area 1. Approximately 75 Tcf of recoverable natural gas has been discovered in Offshore Area 1, the equivalent of 12 billion bbl of oil.
