When encountering losses, the priority is to determine the type of mud losses which will help you choose the suitable size and material for bridging or plugging material for the loss zone. Below is how to differentiate between them: Bridging Material Mechanism In Formation Structure Losses If losses are into the formation structure then our …
The shale shakers are the first mechanical treatment of the returning drilling fluid for solids control. None of the other mechanical devices can cope with solids control without the pre-treatment of the mud in the shale shaker. A shale shaker or vibration screen is a spring-mounted screen. The vibration of the such screen is by …
Shale Shaker performance Design is a function of: The impact of each is discussed in detail in the previous article (please check the link for each article). Guidelines for shaker and screen selection are also provided. Vibration Patterns Design For Shale Shaker Shale shakers are classified in part of the vibration pattern made by the …
Die Collars (box taps) and taper taps fishing tools are two types of attachments that are used in fishing operations to screw into a fish. Die Collars have threads on the ID, which cut threads into the OD of the fish, externally engaging the pipe. Taper types are used to engage the inside of a …
In open hole well logging operations, well conditions are frequently such that the logging tools become stuck (pipe sticking guide), bridged over, or the line becomes keyseated (Drilling Keyseat) in the wall of the hole. When this happens, the wireline operator will feel anxious, and sometimes he may pull too much which will lead to …
Wireline parted in the hole can be retrieved with either a center prong rope fishing spear, double prong spear, or crank type spear. A typical bottom hole assembly used to fish for wireline would consist of the following components: In cased holes, always run a stop on top of the spear that is 1/8″ to …
Biden said at the White House about banning the Russian oil and gas : The day before, Canada became the first G7 country to abandon Russian oil. Prime Minister Justin Trudeau: “This measure sends a powerful message”. The American ban is more than a symbol. It shakes the energy market, it can lead to political …
The Lead Impression Block in oil and gas is designed to give an imprint of the top of a fish in the hole to help determine the condition and position of the top of the fish. The Impression Block can also be used to give clues on how to retrieve an unknown fish in the …
The side door overshot method is another option for freeing a stuck logging tool. In this method, the line is not cut and a rope socket overshot is not required. However, cut & thread fishing is typically the best option. Applications The Bowen Series 160 fishing overshot is only recommended for fishing in cased-hole environments …
The cable guide method or “cut and Thread” method is one technique for fishing stuck wireline (Check also: Sticking Pipe) and/or logging tools. Even though it is dangerous and time-consuming, the cable guide method is preferred over the side door overshot method as it is the surest method. This method is used for retrieving wireline …
