Aenert news. Energy Market & Energy StatisticsEMBER's seventh annual European Electricity Review 2023 (CC BY-SA 4.0) analyzes the EU-27's progress in the transition from fossil fuels to clean power, providing data on electricity generation and demand in 2022 and making a forecast for 2023. In general, EМBER records an acceleration of the electricity transition in 2022, not least because of Russia's invasion of...

Aenert news. Invention analysisPreviously, we published articles concerning chemical stimulation (18.04.2022), gas injection or water flooding (09.05.2022), and steam injection (06.08.2022) technologies used in unconventional oil production, and, specifically, about Steam-assisted gravity drainage approach (06.12.2022). Now we will consider a group of inventions disclosing technical solutions in...

Aenert news. Energy Market & Energy StatisticsAs every year, Baker Hughes has published 2022 rig counts for major regions and countries on its website in January. A change in the number of rigs may be indicative of the level of business activity in the oil and gas sector and form the basis for forecasting future oil and gas production. After a staggering 38% decline in the number of active rigs in 2020, the...

Previously, we published articles concerning the problems of high costs of equipment repair and replacement in directional drilling technology (18.11.2022), and equipment and procedures for well deflecting wellbores during the drilling process and correction of such deflection (27.11.2022). Here we will analyse patent documents related to solving environmental problems arising during directional drilling. In recent years,...

In heavy and extra-heavy oil production, steam stimulation is one of the most commonly used approaches for enhancing the recovery process. Thermal energy of injected steam reduces the viscosity of oil to improve its mobility and facilitate the production process. Conventionally, steam stimulation can be performed by using various technologies, such as Steam-assisted gravity drainage (SAGD), Cyclic steam stimulation, and Steam flood....

In continuation of the previous article dated 18.11.2022, dedicated to patent analysis of inventions related to the repair and replacement of directional drilling equipment, here we will consider patent documents that offer technical solutions related to the technological operation of the controlled deflection of drilling direction. In the technology of directional drilling, a crucial role is played by equipment that allows the...

In the last two decades directional drilling has been rapidly developing in various oil and gas producing countries, primarily in the United States. It has become particularly indispensable for shale gas and tight oil plays. According to U.S. Energy Information Administration (Today in Energy, June 6, 2019), in 2018 in the US the share of horizontal wells in the production of shale gas and tight oil comprised 96-97% against 14-15% in...

In previous comments dated 03/11/2022 and 28/10/2022, we presented our thoughts regarding the current status of Small-scale GTL technologies, as well as the results of a statistical analysis of patenting activity in the field of syngas production by Small-scale GTL. In this note, we will try to analyze the main trends in recent patent solutions. One of the most popular trends in patent solutions related to the production of syngas by...

Small-scale GTL plants are complex technical structures in which technological operations are sequentially carried out to convert raw organic feedstock, first into synthesis gas, and then into various hydrocarbons. Presently, such plants are manufactured by several companies, mainly for use in remote areas of oil production for the beneficial utilization of associated gas. In a previous comment dated 28/10/2022, we reviewed the current...

Gas to Liquid (GTL) technologies have several stages of long and relatively successful development, as well as a fairly developed infrastructure for their application. On the one hand, the now long history of operation of large GTL plants in Qatar, South Africa, Malaysia and Nigeria demonstrate the attractiveness of this technology, but on the other hand, high capital costs and troublesome dependence on the changing conditions of the...
