In the oil and gas industry, ensuring the highest level of production is often a matter of intervention in existing wells. The two most frequently employed technologies for well intervention are hydraulic workover units and snubbing units. While they share several operational similarities, notably in their capacity to work under pressure, however, they differ in their designs, capability, safety, and range of applications. Knowing the…

In the constantly evolving field of oil and gas well intervention, the combined use of coiled tubing and snubbing has emerged as an effective and versatile method to tackle the most difficult downhole challenges. Through using the strengths of both technologies, operators are able to perform a wider range of operations under pressure, reducing non-productive time and enhancing safety and efficiency. What is Coiled Tubing…

In oil and gas exploration, the way a well is drilled can make or break the project, affecting everything from speed and safety to the final cost. Balanced drilling has recently moved to the spotlight because it controls underground pressure almost perfectly, reducing the risk of blowouts or lost circulation. So, what exactly is balanced…

Wireline logging is a must-have step in oil and gas projects. It sends special tools down a borehole to collect clear data about rock layers, show where hydrocarbons sit, and help teams fine-tune how much oil or gas a well can produce.   In this post, we’ll break down what wireline logging is, walk through its…

Offshore oil and gas exploration is one of the most dangerous working conditions in the world, and the crew safety on offshore rigs has become of paramount matter of concern. To meet the growing regulatory requirements and the ever-growing complex offshore operations, safety engineers and designers are continually innovating to develop new designs that significantly enhance the crew’s safety on offshore rigs. This…

The prevention of blowouts during offshore drilling operations is both multifaceted and extremely difficult. As with any drill activity, there are safety protocols in place to avoid unfortunate accidents, but they can be very costly in terms of time and money when dealing with high-pressure subsea wells, making safety essential for success. This article describes the…

Top drive systems are the foundation of modern rotary drilling, providing improved control, greater flexibility and more safety when compared with traditional rotary table systems. In the current oil and gas industry, which moves into more challenging environments, including high-temperature and high-pressure (HPHT) wells, offshore ultra-deepwater fields, etc, the ability to optimize the top drive system is crucial to maximize performance, reducing non-productive…

Although conventional oil and gas drilling methods remain prevalent, slimhole drilling is gaining traction due to its cost-reduction benefits. As new unconventional reservoirs are being explored these days, as well as with the global demand for a reduced ecological footprint clamouring, this technology is swiftly becoming a remarkable answer. This guide will cover the basics of…

Drilling high-temperature and high-pressure (HTHP) wells comes with an array of unique technical challenges that require innovative engineering solutions. Among these, the design and management of the drilling fluids is one of the most important factors that affect the safety, success, and efficiency of the operations. Drilling fluid engineering for HTHP wells requires carefully selected and optimized fluid systems that maintain…

Hydraulic fracturing is commonly referred to as fracking, has changed the global energy landscape through the ability to extract tight oil and shale gas resources previously thought to be uneconomic to extract. By improving the permeability and strength of rock formations with low porosity, the technique has uncovered vast hydrocarbon reserves, which have transformed the energy markets, ensuring energy security for a variety of…
