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…
