The outlook for the well cementing market within the oil and gas production industry in Russia has been impacted by several factors including fundamental sectoral trends, technological conservatism, competition between oilfield services, and specific management challenges. This article briefly reviews all these factors, with a focus on the key aspects …

Long-term field development plans dictate that a variety of well services are carried out in order to increase well productivity. Perforation jobs (perforation of previously unperforated intervals and reperforation) are one of these methods. Perforation is relatively low cost, and its effect can be predicted based on a small amount …

Effective well stimulation with hydraulic fracturing requires indepth engineering and technological research. This paper shows various ways of optimizing multistage fracturing operations in reservoirs with weak barriers with low stress contrasts. One of the solutions is to optimize the existing guar fluid systems to control the fracture height. The following …

There are thousands of paths that lead to delusion, but there is only one leading to the truth. Jean-Jacques Rousseau, 1712–1778. This article is part 2, following part 1 that appeared in ROGTEC Issue 57 This paper presents a critical analysis of the existing concept used to determine the rate …

In 2015, at a meeting of the Presidential Commission for Strategic Development of the Fuel and Energy Complex and Environmental Safety, a resolution was adopted regarding the creation of a national system for professional training on «Well Control. Managing a Well with Oil, Gas and Water Shows». With the view …

Each year there is greater implementation of modern digital technologies at major oil and gas companies. The market players highly appreciate the various economic benefits and notice that digitalization is an effective way to increase competitive advantage. However, the professional community does not yet know how to best employ digital …

Since 2011, most of the newly-commissioned wells delivered by Gazprom Neft’s drilling units have been horizontal wells (HW) with multi-stage hydraulic fracturing (MSHF). To date, about 2,700 horizontal wells with MSHF, equipped with ball-drop-activated “packer-and-port” liner assemblies (uncemented), have been drilled in the Company’s fields, out of which about 800 …

When geosteering is required, there is no substitute for geologic and engineering knowledge …

Over the last few years, the well workover market has been growing steadily, despite periodic crises in the oilfield service market and oil and gas industry. There was a strong reason for this – deterioration of the well stock forced the market to increase the number of workover operations. This …

Despite the accelerating technological developments enabling the use of various alternative energy sources, the world is currently facing an increased demand for hydrocarbon (HC) supplies [1, 2], hence the need for reserve replacement. This is certainly possible in Russia over the next two to four decades (2020–2060s) [3], but only …
