In the world of drilling and well completion, industry jargon is as thick as the mud itself. One such term, "possum belly", is surprisingly versatile, referring to two entirely different things depending on context.
1. The "Possum Belly" as a Mud Receiving Tank:
This "possum belly" sits at the end of the mud return line, acting as a vital component in the mud circulation system. The mud flows into the bottom of this tank, effectively creating a "belly" where the mud collects. From here, the mud flows upward, enabling controlled mud flow over the shale shaker. This process is crucial for removing solids and maintaining the desired mud properties, ensuring optimal drilling conditions.
2. The "Possum Belly" as a Pipeline Repair Toolbox:
In this instance, "possum belly" describes a metal box located beneath a truck bed. This box is specifically designed to house a variety of tools necessary for pipeline repair. Its position under the truck bed makes it easily accessible, ensuring swift and efficient access to crucial tools during pipeline emergencies.
Beyond the "Possum Belly": A Peek into Drilling Terminology:
These two distinct meanings of "possum belly" highlight the complex and specialized language used within the drilling and well completion industry. Other commonly used terms include:
While these terms may seem obscure to the uninitiated, they are essential for understanding the complex and demanding world of drilling and well completion.
By embracing the language of this industry, we gain a deeper appreciation for the critical role it plays in securing our energy resources and sustaining modern society.
Instructions: Choose the best answer for each question.
1. What is the "Possum Belly" in the context of mud circulation? a) A type of drilling bit
Incorrect. A drilling bit is a different component of the drilling process.
Incorrect. While there are specialized tools for well completion, the "Possum Belly" in this context is related to mud circulation.
Correct! The "Possum Belly" acts as a tank for collecting mud before it flows through the shale shaker.
Incorrect. Safety devices on the rig include blowout preventers (BOPs), not the "Possum Belly".
2. What is the purpose of the "Possum Belly" in the mud circulation system? a) To mix mud with additives
Incorrect. While mixing mud is essential, the "Possum Belly" primarily deals with collecting and filtering mud.
Incorrect. While mud is stored in larger tanks, the "Possum Belly" is specifically for collecting and filtering it during circulation.
Correct! The "Possum Belly" helps control mud flow and allows for efficient removal of solids before the mud is returned to the wellbore.
Incorrect. Blowouts are prevented by the blowout preventer (BOP), not the "Possum Belly".
3. Where is the "Possum Belly" found in the pipeline repair context? a) Inside the drilling rig
Incorrect. The "Possum Belly" for pipeline repair is found on a truck, not inside the drilling rig.
Correct! The "Possum Belly" in this context is a toolbox specifically located under the bed of a truck for easy access during pipeline repairs.
Incorrect. The "Possum Belly" as a toolbox is not found in the wellbore.
Incorrect. The wellhead is the point where the wellbore connects to surface equipment, and the "Possum Belly" is not related to this location.
4. What is the primary function of the "Possum Belly" as a pipeline repair toolbox? a) To store heavy equipment for pipeline installation
Incorrect. While heavy equipment is used in pipeline installation, the "Possum Belly" is designed for repair tools.
Incorrect. Pipeline sections are usually transported on specialized trailers, not in the "Possum Belly".
Correct! The "Possum Belly" is designed to store a variety of tools essential for swift pipeline repair in emergency situations.
Incorrect. While cleaning and lubrication are important, they are not the primary function of the "Possum Belly" toolbox.
5. Which of the following terms refers to the entire drilling apparatus? a) Mud
Incorrect. Mud is a drilling fluid, not the entire apparatus.
Incorrect. Completion refers to the process of preparing a well for production, not the drilling apparatus.
Incorrect. A BOP is a safety device, not the entire drilling apparatus.
Correct! The "Rig" encompasses the entire drilling platform, derrick, and associated equipment.
Instructions: Imagine you are a drilling engineer. You are overseeing a drilling operation, and the "Possum Belly" (mud receiving tank) is overflowing with mud. Explain the possible reasons for this overflow and suggest steps to rectify the situation.
