Formation evaluation in unconventional reservoirs, such as shale gas, tight oil, and coalbed methane, presents unique challenges due to the low permeability and complex geology of these formations. Traditional well-logging techniques often fail to provide the necessary resolution and accuracy for effective evaluation and development of these resources. Consequently, specialized well-logging techniques have been developed and…

Formation evaluation is a critical aspect of oil and gas exploration and production. It involves the assessment of subsurface geological formations to determine their potential to store and produce hydrocarbons. One of the most effective ways to perform formation evaluation is through the use of downhole tools, which provide real-time data and insights into the characteristics…

Density logging is an essential technique in the oil and gas industry. By measuring the bulk density of subsurface formations, this method provides critical insights into the geological structure, helping in reservoir characterization, formation evaluation, and resource estimation. What is Density Logging Density logging is a type of well logging that measures the electron density of rock…

Well cementing is serving as the backbone for well integrity and long-term production efficiency in oil and gas operations, ensuring the isolation of different subterranean formations and providing structural support to the wellbore. Evaluation and diagnostics in well cementing are essential to ensure the operation is successful and to prevent potential issues that could compromise the well. Importance of Evaluation and Diagnostics…

Understanding…

Well logging, the practice of recording geological and petrophysical data from boreholes, provides crucial insights into reservoir properties, formation characteristics, and fluid compositions. Traditional well logging tools have served the industry well, but the demand for more comprehensive data and operational efficiency has spurred the development of multifunctional well logging tools. In this article, we delve…

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…

Cement bond logging is used in the oil and gas industry to evaluate the integrity of the cement bond between the casing and the surrounding rock formation. This process is essential for ensuring that the cementing job performed during the well construction phase has been effective, providing proper zonal isolation and preventing fluid migration between different formation…

Drilling a dry hole–a well that fails to produce commercial quantities of hydrocarbons–can cost millions in wasted resources and is avoided through accurate well logging by providing reliable subsurface data, optimizing drilling decisions, and increasing production efficiency. This article investigates the economic benefits of precise well logging by showing its effect in decreasing dry holes while…
