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.
In need of an exploration boost, Norway doled out a record 83 production licenses in mature areas of the Norwegian Continental Shelf to 33 firms. Norway hopes for a continued rise in offshore exploration and development activity to ensure steady oil and gas production through the next decade. Equinor has grabbed seven new licenses in the Barents and Norwegian Seas, the latest in a flurry of offshore activity in which the firm has added acreage off the UK and Brazil, gained approval for a big Arctic project, and awarded billions of dollars in service contracts. A reservoir-conditions coreflood study was undertaken to assist with design of drilling and completion fluids for a Norwegian field. Multiple fluids were tested, and the lowest permeability alterations did not correlate with the lowest drilling-fluid-filtrate-loss volumes.
The firms are now partners on multiple blocks in the North Argentina Basin. Australia’s BHP Billiton and the recently acquired Anadarko Petroleum submitted the largest dollar totals of high bids in US Gulf of Mexico Lease Sale 253. Using maglev technology, a new artificial lift system seeks to boost production output by sucking down reservoir pressure from inside the wellbore and from inside the reservoir. The Norwegian operator will increase its ownership of the giant Johan Sverdrup field before the field commences oil production this November. The round marked a continuation of a recent trend on the UKCS in which lesser-known firms and newcomers have gained stature, replacing more-familiar, bigger operators that have pared down their North Sea positions.
The author argues that the advent of cloud technology should not be regarded as a further challenge to security but an opportunity to revitalize and improve a company’s defenses dramatically. A comeback in offshore and international exploration and production is making up for the North American slowdown, but it is a difficult transition. The Bakken and Niobrara operator will eliminate 254 jobs in an effort “to better align [its] business with the current operating environment.” 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.
The $5.6-billion deal includes the Prudhoe Bay field and the Trans Alaska Pipeline and vaults Hilcorp to be the second-largest Alaska producer and reserves holder, behind only ConocoPhillips. The green light comes 4 years after the privately-held firm filed its development and production plan. Liberty Island would consist of gravel, stretch 9 acres, and sit just a few miles offshore. The technology will provide Equinor a continual feed of updated reservoir information from its Johan Castberg and Johan Sverdrup fields with the aim of improving well placement, production, injection, and—ultimately—recovery.

The discovery marks London-based Tullow’s first operated contribution to a long list of discoveries since 2015 in the emerging petroleum province. The large independent put together a team of data scientists, software developers, and petrotechnical staff to create a forward-looking vision for how to use digital technology to solve problems. Leaders from two large US onshore rig contractors said their expectations that the rig-count slide would hit a second-quarter bottom were off and are now refraining from making new predictions as to when it will end. The Italian operator reported positive appraisal and exploration results from wells drilled some 10,000 km apart. The green light for Santos Energy’s drilling program in the McArthur Basin comes after a moratorium on hydraulic fracturing in the Northern Territory was lifted in 2018.
The $5.6-billion deal includes the Prudhoe Bay field and the Trans Alaska Pipeline and vaults Hilcorp to be the second-largest Alaska producer and reserves holder, behind only ConocoPhillips. The shale sector is making moves to consolidate amid investor pressure to increase cash flow. This deal will form the second-largest producer in Colorado’s DJ Basin. The firms are now partners on multiple blocks in the North Argentina Basin. Australia’s BHP Billiton and the recently acquired Anadarko Petroleum submitted the largest dollar totals of high bids in US Gulf of Mexico Lease Sale 253.
Africa (Sub-Sahara) San Leon Energy reported encouraging performance from its OML 18 field in Nigeria. Reperforation of an oil well increased gross field production to approximately 61,000 B/D before output was temporarily scaled back to 53,000 B/D for a shut-in, upgrade, and workover of the well. A number of other field wells will be reperforated in coming months, the company said. San Leon holds a 9.72% interest in the field, which is operated by Eroton (35%). Nigerian National Petroleum Corp. holds the remaining stake. FAR said that drilling has begun on the SNE-5 appraisal well offshore Senegal. The well and the following SNE-6 well will evaluate the upper SNE reservoir units' connectivity and deliverability by oil flow testing that will include interference tests.

With the flourishing shale gas exploitation produces more oil based mud (OBM) drill cuttings, the hardto-treat hazardous wastes burdens the local environment heavily. However, the problems of high energy consumption, high treating cost and high risk secondary contamination still remain unsolved for mainstream technologies such as thermal distillation, incineration and chemical extraction. Therefore, a new method and device based on cyclone desorption of high speed self rotation to dispose of OBM drill cuttings is put forward to overcome the challenge. The working process includes: viscosity reduction in heated gas; cyclone deoiling; condensation and recycling of exhaust; separation of oil and water in coalesce. It is found that the self-rotation speed of solid particles in a 3-dimensional rotating turbulent flow field of cyclone is as high as 2,000 to 6,000 rad/s which coexists with evolving speed of s The remarkable pulsing centrifuge force in the rotation and revolution coupling motion can enhance the desorption process of the oil so as to accomplish the separation and enrichment of oil and solid phase, and deep removal of organics from OBM drill cuttings.
Equinor drilling operations at the giant Johan Sverdrup field, where production is slated to start up this year. Similar development opportunities will be needed to sustain Norwegian production through the next decade. Norway’s energy ministry on 15 January awarded 83 production licenses in the North, Norwegian, and Barents Seas to 33 firms, topping the country’s year-old record of most licenses awarded in a round. Native operators Equinor, Aker BP, DNO, and Lundin Petroleum were leaders among a group spanning large, multinational firms and smaller European independents focused on the Norwegian Continental Shelf. The licenses, distributed as part of the Awards in Predefined Areas (APA) 2018 round, cover already-explored areas where existing knowledge and facilities can be leveraged to find and develop new oil and gas deposits.
