Wireline logging is essential in evaluating wells by providing high-resolution data about  formation’s properties, fluid content and well integrity. In High Pressure High Temperature (HPHT) wells, the wireline logging becomes much more crucial and more complicated. These extreme environments, typically defined by pressures greater than 15,000 psi and temperatures exceeding 300°F (150°C), demand advanced tools, techniques and meticulous planning to ensure successful operations. This…

In the oil and gas industry, efficient management of a wellbore’s productivity and maintaining the well’s structural integrity over time are essential for efficient operations. One of the important methods of monitoring the well condition post casing setting and cementing is cased hole logging. This article delves into the definition of cased hole logging, describes…

Well intervention is a key procedure in the oil and gas industry since it allows operators to maintain, repair, or enhance production economically and without expensive workovers. Snubbing and coiled tubing are two of the most common methods used for well intervention. Now, the question is. Which is more efficient? This is the question we…

In the oil and gas industry, digital transformation technology is increasingly used to improve efficiency, reduce costs and optimize production. Digital twins technology has become an innovative force, providing real-time visualization, analysis and optimization of complex oil production systems. Digital twins are dynamic virtual model that reflects the physical behaviour of processes, assets or even entire production systems, by continuously integrating real-world data. When applied…

This offshore drilling industry is going through a technological transformation as autonomous technologies is redefining how energy is explored and extracted beneath the ocean floor. Autonomous offshore drilling rigs, powered by the advancements in artificial intelligence (AI), robotics and real-time data analysis, are becoming a revolutionary solution to enhance efficiency, safety and cost-effectiveness in deepwater drilling. Why Need Autonomous Offshore Drilling Rigs Offshore drilling platforms traditionally…

As a critical technique within the petroleum field, sidetracking drilling enables increased production, overcomes logistical challenges, and examines previously inaccessible geological formations and reservoirs. The approach is equally valuable in the event of a stuck drillpipe and in cases where new reservoirs need to be tapped into through existing wellbores. This article discusses the mechanics of…

In today’s ever-evolving oil and gas industry, maximizing production efficiency is very important. In recent years, dual completion technology has become a popular innovation. This technology allows operators to produce from two zones in a single wellbore, thereby increasing production efficiency while reducing overall drilling costs. What are the Basics of Dual Completion Dual completion is…

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…
