Daniel Skorov, a reservoir engineer of PETEC Ltd., published in the journal “Science and Technology in the Gas Industry” an article “Numerical simulation of gas-hydrates formation in the context of the fluid flow to a part of a horizontal well”. Numerical simulation of gas-hydrate formation due to a throttling process using CMG STARS is described in this paper. This process is considered in the context of a part of a horizontal well. According to the results of this work, the amount of hydrates is evaluated. The results received in this paper could be a basis for planning and the effectiveness assessment of a well productivity enhancement.

Daniel Skorov, a reservoir engineer of PETEC Ltd., took part in the High-Viscosity Oil section of the SamaraNIPIneft Science and Technology Forum. The report presented approaches to model using CMG software:

  • foamy oil effects;

  • waxes precipitation and dissolution;

  • the complex technology for development of the Bazhenov formation.

The results obtained are consistent with physics of in-situ processes, which necessitates the use of CMG software to model development of heavy oil reservoirs and unconventional hydrocarbon resources.

Daniel Skorov, a reservoir engineer of PETEC Ltd., published in the journal “Automation, telemechanization and communication in oil industry” an article “The enhanced oil recovery methods applicability assessment using an artificial neural network”. In this article an approach to assessing the applicability of EOR using an artificial neural network (ANN) is considered. It is shown that the choice of EOR made by the network matches with the actual application with an accuracy of 80%. EOR applicability assessment based on the ANN is recommended to be carried out at the initial stage of EOR method selection.

Daniil Skorov, PETEK, paper in the journal "Exposition Oil Gas": “Estimation of fracture parameters of multistage hydraulic fracturing based on monitoring of the inflow profile” about innovative automated approach to determining the geometry and flow parameters of fractures n a horizontal well with multistage hydraulic fracturing with deposition of quantum marker-reporters on proppant. CMG's CMOST software tool was used for modeling well inflow profile to identify fracture parameters and significantly improved the quality of 3D reservoir simulation model history match.

NEW RESEARCH GIANT NAMED NORCE 

2018

 

NORCE Norwegian Research Center AS (NORCE) was founded in July 2017 to create a powerhouse for research that will lead the way in innovation, value creation and research.

 

In January 2018, NORCE took over the ownership of Uni Research AS, the International Research Institute of Stavanger AS (IRIS), Christian Michelsen Research AS (CMR), Agderforskning AS and Teknova AS. The business was fully integrated in the autumn of 2018 when the five former institutes were merged into NORCE. In December 2018, NORCE took over the ownership of Norut Northern Research Institute AS, which was merged into NORCE in 2019.

The owners' ambitions are for NORCE to:

  • contribute to change and innovation in the private and public sectors

  • strengthen research-based innovation and development

  • increase their national and international competitiveness

  • increase opportunities for their competence to be used across disciplines and sectors

  • increase their chances when competing for EU research funding 
     

Drawing on expertise in such a wide range of fields, and of such a high calibre, NORCE is uniquely equipped to deliver new knowledge and innovative solutions that will be important and useful – regionally, nationally and globally. 

The owners wish to use the merger to build an influential entity. Commissioned research increasingly takes place in an international market, which makes being a large player advantageous.

NORCE benefits from maintaining a presence along much of Norway's coast, and will work towards southern and western Norway, as well as Norway as a whole, gaining a more prominent role in innovation and commissioned research. NORCE will also ensure that the many productive and technologically-leading businesses in the region continue to lead the way in the changes to come in Norwegian manufacturing and business in the years ahead. Good synergies between these companies, a large research group and the universities will be of great value here.

PETEC’S 15 YEARS ANNIVERSARY 

 

 

In 2016 PETEC marked its 15-year anniversary. In the framework of this event on November 10-11 we held scientific-technical seminar “New technologies of extraction of hydrocarbons in a changing world”. At the seminar presentations on recent achievements and development in new research areas were made by our partners, IRIS, CMG, AGR. We thank all the speakers and guests of the workshop who took part in the anniversary, and express our openness to mutually beneficial cooperation!
