Transporting oil from production sites to refineries, markets and other facilities is a difficult task under normal circumstances. When operations are extended to extreme environments, such as the Arctic, high-altitude terrains and deep oceans or political unstable regions, the challenges increase dramatically. To ensure safe, efficient and sustainable oil transportation in these regions requires sophisticated technology, meticulous planning and compliance with international standards. Challenges of…

The integration of snubbing units in Plug and Abandonment (P&A) operations is increasingly becoming a strategic choice for well decommission, particularly in high-pressure or complex conditions. Snubbing units allow the handling of live wells, without killing them, offering a safe and effective method for sealing and isolating the end-of-life wells. This article focuses on the function of snubbing units in P&A, the benefits they provide, their key operational considerations,…

When it comes to well completions in the oil and gas industry, two key terms often come up: lower completion and upper completion. Understanding the differences between these two types of completions is crucial for optimizing production and ensuring well integrity. What are the Types of Well Completions Completion in oil and gas wells is to…

Well logging is a critical process in the oil and gas industry. It gives valuable information about subsurface formations. Two main methods for well logging include open hole logging and cased hole logging, each of which serve different functions in various stages of well construction and is selected according to the operating stage of the well and the type of data required. Knowing their advantages, limitations, and differences can help engineers…

Coiled tubing has emerged as an essential component of the modern oil and gas well interventions, particularly for stimulation techniques like hydraulic fracturing or acidizing. The ability to deploy continuous, flexible tubing into live wells without the need for a conventional workover rig has revolutionized how operators manage downhole activities. This article explains the use of coiled tubing for hydraulic…

Workover operations are needed to sustain and enhance oil and gas well productivity. Wells over time may experience reducing production, mechanical failure, or reservoir issues that require repairing. Well workover operations restore or improve well performance to produce hydrocarbons economically. We are going to explain in this article why oil and gas workover is inevitable, types of workover…

Acid stimulation is a well stimulation treatment widely utilized in the oil and gas industry. With the objective of increasing oil and gas reservoir productivity, this process involves acid injection in the wellbore to dissolve rock structures or eliminate formation damage. In this article, we cover the types, uses, and best practices of acid stimulation of…

Coiled tubing has become as an essential tool for oil and gas industry, known for its capacity to perform a wide array of well intervention operations without the need to kill the well or remove the production tubing. As exploration is moving deeper into harsh environments, the deployment of coiled tubing in High Pressure High Temperature (HPHT) wells presents…

Oil transportation, whether through pipelines, tankers, rail or road, is crucial in the global supply chain of energy. However, it also poses substantial risks for personnel, communities, and the environment. Transport accidents can result in massive spills, fires, and even explosions. Thus, comprehensive safety training is a critical element to ensure efficient, safe, and legally compliant oil transportation operations. Why Safety Training…

The oil and gas industry is the most challenging and dangerous of all industries, where minor errors can lead to catastrophic accidents. State-of-the-art oil drilling animation has now emerged as an essential tool in training, planning, and safety protocols to mitigate these risks. With visualization of the drilling process animation, workers and engineers can be informed…
