Mud gas separators are commonly used during oil drilling operations, particularly in situations when extraction is likely to yield a large volume of gas. Often referred to as degassers, these systems offer many benefits when drilling operations are centered on mud columns that are below optimal balance, and in so-called “sour gas” environments when there is a high concentration of hydrogen sulfide in the drilling fluid.

Working theory of mud gas separator

The gas cut drilling fluid enter into separator from the separator inlet month, after impacting with the impact plate, scattered in a series baffle, crashing and increase and reveal the surface area, then downward flow causing the flocculated flow state, make the gas separation with drilling fluid. The free gas is discharged through the gas outlet of the top tank, the length of the exhaust pipe is decided and installed by the field and is lead to the safe place, but the after degassing drilling fluid flow into circulating tank through drilling fluids shale shaker.

Each mud gas separator has limitation on much it can safely handle volume of gas. If the volume of gas exceeds the maximum limit, gas can blow through into the rig. It is very important that you must estimate gas flow rate on surface based on pit gain and kill rate in order to see how much expected gas on surface. This will be the
limitation on how much you can circulate for well killing operation. You can estimate the volume gas on surface by using well control kill sheet provided by several companies. You need to ensure that the vent line should be as straight as possible with a larger ID in order to minimize back pressure while venting the gas out.

Mud gas separator of drilling fluid circulation system

Mud gas separator (also called poor boy degasser or gas-buster) is a vertical vessel which is used to remove undesired gas from drilling mud when it returns from the well while circulating mud in order to control the well. Mud gas separators are commonly used during oil drilling operations, particularly in situations when
extraction is likely to yield a large volume of gas.

Major types and features of DC Solid control Mud gas separator

Mud gas separator (also called poor boy degasser or gas-buster) is a vertical vessel which is used to remove undesired gas from drilling mud when it returns from the well while circulating mud in order to control the well. The mud gas separator is designed in multiple capacities, to meet specific drilling rig conditions.

There are three three major types of mud gas separators:

1. Open bottom: These separators are often called “poor boys,” and immerse the bottom of the machine in the mud deposit.
2. Closed bottom: A closed bottom mud gas separator features a sealed base, which directs the mud return into the storage tank.
3. Float: The float design is similar to the closed bottom type of separator, except that it has a valve rather than a permanently sealed line for the mud return. Fixed or elevated pedestals are also used to mount the base.

DC Solid control can design and fabricate the poor boy in varying sizes and lengths to meet your specific drilling conditions.

Pertinent features of the Mud gas separator from DC Solid control

In the oilfield, the mud gas separator is sometimes known as “poorboy degasser” or “gas buster”. They may be vertical or horizontal in design.

A vertical separator is normally used for high fluid throughput, while a horizontal separator provides a longer retention and superior gas separating capacity. Internal design and configuration governs the individual efficiency of the equipment.

The mud gas separators should be designed to a recongised pressure vessel code. To avoid plugging by solids, hydrates or mechanical malfunction, the separator back pressure should be controlled by a liquid seal rather than conventional back pressure regulators or liquid level control valves. A pressure gauge is required to monitor the pressure in the separator vessel.

What will making mud gas separator blow-through.

DCZYQ Mud gas separators are intended to sustain safety for high pressure wells. Our units are closed bottom skid mounted model designed around safety and precision. Uniquely designed baffles break up mud and gas which is then expelled by the gas vent line to the flare line.

But what will cause the mud gas separator blow-through.

1. Friction pressure of the gas venting through the vent line exceeds the mud-leg hydrostatic pressure, resulting in evacuation of fluid from the separator. Friction pressure of the mud through the mud return line is considered negligible because of its short length.

2. Vessel ID is too small, causing insufficient retention time for the gas to separate efficiently from the mud. This situation is commonly called insufficient separator cut.

To estimate a peak gas flow rate properly, we must consider a “typical” kick. The typical kick will depend on the well location, depth, type size, and component ratios of influx. Kick data should be based on previous offset well data and should be a realistic worst-case gas kick.

Matching using the mud gas separator and vacuum degasser in mud system

In oilfield mud system, there are two equipment used for removing the harmful gas from drilling fluids. They are mud gas separator and vacuum degasser.

Vacuum degassers utilize negative pressure to withdraw entrained gases from the mud. In order for this to work, mud is pumped through a venturi, which develops a negative pressure, thus sucking mud into the unit. The mud then flows over dispersion plates, arranged either horizontally or vertically, creating thin sheets of gas-cut mud. These dispersion plates bring entrained gases closer to the surface for easy removal by a stand-alone vacuum pump. The choice between horizontally or vertically mounted units is typically based on the footprint requirements of the specific rig.

vacuum degasser

Degassers are used to remove the small entrained gas bubbles left in the mud by the mud/gas separator. These units are positioned downstream from mud/gas separators, gumbo removal equipment (if utilized), shale shakers and mud conditioners (if utilized), while hydrocyclones and centrifuges follow in the arrangement.

Mud/gas separators and degassers mechanically remove entrained gases such as hydrogen sulfide, carbon dioxide and natural gas from the mud system. Entrained gas can reduce the hydrostatic head of the mud column and can cause catastrophic well control problems. BRANDT manufactures both mud/gas separators and degassers.

Mud/gas separators are the first units of solids control equipment arranged to treat mud. As such, they process all of the mud from the flowline before the mud reaches the primary shale shakers. The units have no moving parts and rely on the density difference between the gas and the mud for removal. The process is simple, yet very effective.
