This study examines which is the margin of usability for Artificial Intelligence (AI) algorithms related to the rock properties distribution in static modeling. This novel method shows a forward modeling approach using neural networks and genetic algorithms to optimize correlation patterns among seismic traces of stack volumes and well rock properties. Once a set of nonlinear functions is optimized in the well locations, to correlate seismic traces and rock properties, spatial response is estimated using the seismic volume. This seismic characterization process is directly dependent on the error minimization during the structural seismic interpretation process, as well as, honoring the structural complexity while modeling. Previous points are key elements to obtain an adequate correlation between well data and seismic traces. The joint mechanism of neural networks and genetic algorithms globally optimize the nonlinear functions and its parameters to minimize the cost function. Estimated objective function correlates well rock properties with seismic stack data. This mechanism is applied to real data, within a high structural complexity and several wells. As an output, calibrated petrophysical time volumes in the interval of interest are obtained. Properties are used initially to generate a geological facies model. Subsequently, facies and seismic properties are used for the three-dimensional distribution of petrophysical properties such as: rock type, porosity, clay volume and permeability. Therefore, artificial intelligence algorithms can be widely exploited for uncertainty reduction within the rock property spatial estimation.
Anchored by the Khaleesi-Mormont and Samurai fields, the King’s Quay FPS will receive and process up to 80,000 B/D of crude oil. Murphy Oil to Buy Deepwater US Gulf Assets for up to $1.625 Billion The El Dorado, Arkansas-based Murphy has quickly found a home for some of the cash it will receive from the sale of its Malaysia business. The company has been rapidly expanding its US gulf footprint while simplifying its portfolio and targeting more oil. PTTEP to Buy Murphy Oil’s Malaysian Business for $2.1 Billion Thailand’s PTTEP is doubling down on Malaysian oil and gas in an effort to broaden its reach in its native Southeast Asia. The new venture will operate several deepwater assets—including the Cascade, Chinook, Medusa, and Thunder Hawk fields.
Megaprojects have come to define many of the world’s new resource projects but they are also a testament to the awesome engineering capabilities of the oil and gas industry. Find out who took home this year’s honors. Shell and SBM Offshore won recognition for their Gulf of Mexico Stones field development. The OTC Distinguished Achievement Award will be presented during a luncheon on 1 May at the Offshore Technology Conference in Houston. Gene Kouba was recognized with the Projects, Facilities and Construction award during ATCE.
The Italian operator reported positive appraisal and exploration results from wells drilled some 10,000 km apart. UK operator Trident Energy is entering Brazil while Australian firm Karoon Energy is expanding its position in the country. Both will try to boost output from already-producing assets. Findings from Kayrros suggest the average Permian well is both less productive and more expensive than reflected in public data. Mexican President Andrés Manuel López Obrador is prioritizing investment in Pemex over foreign participation as a means to boost the country’s shrinking oil output.
Researchers from the Federal Reserve Bank of Dallas quantified the economic impact of the US shale revolution for the first half of this decade. Production from the Hibernia platform was shut down again on 17 August after its second oil spill in a month, while Husky Energy began to ramp up output from the White Rose field following the largest-ever spill off Canada’s easternmost province. Anchored by the Khaleesi-Mormont and Samurai fields, the King’s Quay FPS will receive and process up to 80,000 B/D of crude oil. Despite reports to the contrary, Permian well productivity remains healthy, with average new production per well in the basin matching all-time highs, Rystad says. Researchers mapped 251 faults in the North Texas home of the Barnett Shale, the birthplace of the shale revolution, finding that wastewater injection there “significantly increases the likelihood for faults to slip.”
Phase 1 production from the deepwater US Gulf of Mexico field is expected to reach 30,000 BOPD. The field contains an estimated 5 billion bbl of oil in place. After suffering major setbacks, Chevron’s massive Big Foot project finally achieved first oil last November in the US Gulf of Mexico. With the setbacks in the rear-view mirror, project personnel spoke about the challenges. BP and partners have sanctioned the Azeri Central East project, the next stage of development of the giant Azeri-Chirag-Deepwater Gunashli oilfield complex in the Azerbaijan sector of the Caspian Sea.
The criticality of above-water riser hull piping requires frequent inspections. Traditional manual inspection methods present safety and efficiency concerns, but work is being done to see if robotic technologies—such as drones and crawlers—can do the job as good as, or even better than, humans. Operators are looking for ways to better handle water coming from subsea wells, which is typically treated at topside facilities. Subsea separation systems are not equipped to discharge water back into the reservoir, so how do companies close the gaps? Shell and SBM Offshore won recognition for their Gulf of Mexico Stones field development.
The subsea tieback is expected to start up in 2021. This is Shell’s second major development on a tieback in the US Gulf of Mexico, following Kaikias’ startup in May. The Bureau of Safety and Environmental Enforcement reported about 14% of oil production and about 14% of natural gas production remains shut in following Tropical Storm Barry. Offshore personnel are reboarding Gulf of Mexico platforms, oil and gas production begins recovery. Operators' reports of evacuated personnel remain unchanged from yesterday.
The subsea tieback is expected to start up in 2021. This is Shell’s second major development on a tieback in the US Gulf of Mexico, following Kaikias’ startup in May. Bravo is the second of four platforms to be decommissioned and removed from the Brent field, following Brent Delta in 2017. The field has produced approximately 3 billion boe since 1976. First cargo from the world’s largest floating LNG project comes in the midst of low LNG prices sparked by a global supply boost.
