Definition – What doesDownhole Tools mean?
Downhole Tools are pieces of oilfield equipment that are used during well drilling, completion and intervention or well workover activities and helps the oil well in optimizing the production levels…
How the Oil and Gas Industry Works
The oil and gas industry is the largest sector in the world in terms of dollar value. It contributes significantly to the gross domestic product (GDP) of many nations and generates billions…
Cased Hole Completions
In cased hole completions, production casing is run along the entire length of the well and through the reservoir. The cased hole effectively acts as a control mechanism for safe…
Open Hole Completion vs. Cased Hole Completion
After drilling operations have been concluded, it becomes necessary for the wellbore to be Completed – the process of preparing the well for the production phase. The entire well completion process includes…
Perforation Fundamentals – Basic Knowledge about Perforation Used in Oil and Gas Industry
Perforation is a special operation to crease an efficient communication path between a wellbore and a reservoir by creating tunnels. The effective paths allow reservoir fluid to flow into the…
Conventional Vs. Unconventional
Upon entering the oil and gas industry, one of the first things I kept hearing was conventional and unconventional oil. At first, I just thought this meant that this was…
Perforating
Perforating is a process used to establish a flow path between the near reservoir and the wellbore. It normally involves initiating a hole from the wellbore through the casing and…
How Does Well Completion Work?
Once a well has been drilled, the decision must be made: Will this well become a producer or be plugged and abandoned as a dry hole? Should the operator decide…
Types of packers
Retrievable tension packer The tension packer (Fig. 1) is typically used in medium- to shallow-depth (LP/LT) production or injection applications. The tension packer has a single set of unidirectional slips…
