GN Solids is a professional oifield drilling mud vacuum degasser manufacturer and supplier in China oil drilling mud solids control industry. As the pioneer in this industry, GN Solids is capable of providing customers with series products ,such as oil & gas drilling fluid solids control equipment, drilling decanter centrifuge, drilling waste management equipment and drilling security equipment.

Application of drilling mud vacuum degasser

To recomve invading gas from drilling mud, it is necessary to install a vacuum degasser. So that the invading gases may not impact mud properties. This invading gases can lead to risks and affect the lifespan of solids control equipment.

Vacuum degasser is a special-purpose oil drilling mud solids control equipment and a new type one for the drilling fluids system. Drilling mud vacuum degasser can get rid of various gases invading drilling quickly. Drilling mud vacuum degasser is very important for keeping mud gravity, stabilizing mud viscosity and reducing drilling cost. At the same time, drilling mud vacuum degasser can be used as a heavy-power mud agitator and supported applicable to all types of drilling mud purification system. The drilling mud vacuum degasser design of the structure is scientific and rational. So we are able to achieve an effective gas-liquid separation, filter out impurities and to ensure that the exhaust pipe is always smooth.

Drill solids are the main contaminant of all drilling fluids and therefore their control is of the utmost importance. There are 3 main ways of controlling solids:

• Dilution

• Mechanical removal

• Gravity Settling

shale shaker for solids control

shale shaker for solids control

I ever saw in the water well drilling site in Mongolia that they do not use any solids control equipments but only dig several mud pits, by this way, it is very low efficiency and Environmental Pollution.

Solids control system is a way for mechanical removal the drill solids. Mainly it includes screen devices & Centrifugal Separation Devices. Screen devices is the most important equipment called shale shaker. In the future of solids control system, shale shaker will become the only solids control equipment which will be used instead of desander, desilter, mud cleaner, decanter centrifuge by improvement of its design. At present, linear motion shale shaker is the most popular vibration mode shale shaker.

But the arrangement of vibration motor various by different shale shaker manufacturer. Sometimes it is vertical installed, sometimes it is horizontal installed, it doesnot mean that horizontal installed shale shaker must be balanced elliptical motion shale shaker, it might be linear motion shaker.

Mud guns are meant to provide supplemental or primary mixing in mud tanks depending on the number being used and the pit size. They are best used in tank corners to keep solids from settling and a mud agitator is placed in the tank center.

How to operate the mud gun?

A. Safty information

TURN OFF. LOCK OUT, and TAG OUT the electrical power supply to the pumps feeding the mud guns before servicing.

Inspect the unit regularly, and replace damaged or worn components only with parts supplied by the original equipment manufacturer.

Before entering a mud tank for any reason, the mud agitators should be locked out and tagged out.

B. General maintenance

1. Grease the swivel once a week. Add (2) shots of a multipurpose NLGI no 2 grease.

2. Visually inspect the mud gun assembly for any leaks, loose fittings once a week. Repair as required.

3. Inspect mud gun jet nozzle for excessive wear. The nozzle has a 5/8” bore when new. The nozzle should be changed when the bore is 7/8” or higher. This should be done once a month.

Once installation is complete, the unit can be started by turning the feed pump on. The direction of discharge may be modified to suit the operators requirements by rotating the swivel.

Drilling engineering is a subset of petroleum engineering. Drilling engineers design and implement procedures to drill wells as safely and economically as possible.

solids control

solids control

Exploration and petroleum engineering are the oil and gas industry’s two main sections. Petroleum engineering is a field of engineering related to the production of crude oil or natural gas.

Drilling engineers are in charge of the process of planning and drilling the wells. Their responsibilities include:

  1. Designing well programs to prevent blowouts
  2. Designing casing strings and cementing plans, directional drilling plans, drilling fluids programs, and drill string and drill bit programs.
  3. Specifying equipment, material and ratings and grades to be used in the drilling process.
  4. Providing technical support and audit during the drilling process.
  5. Performing cost estimates and analysis.
  6. Developing contracts with vendors.

Solids Control is one of the most important phases of the drilling process. The primary reason for using mechanical solids control equipment is to remove detrimental drilled solids from the mud system. Mechanical separation of drilled solids is achieved via screen separation(shale shaker, mud cleaner, desander, desilter) or accelerated g-force(decanter centrifuge). Continue reading »

The Drill cuttings Management solution is designed to help maximize compliance with the waste management hierarchy principles, as well as ensuring that local regulations and standards are complied with. Ultimately, disposal will be required in all cases, be it solids and / or liquids.

drill cutting management solution

drill cutting management solution

Drill cuttings management solution usually including but not limit to:

1 collection of drill cuttings

There are various ways to collect the drill cuttings from the solids control system( shale shaker, mud cleaner, decanter centrifuge). Firstly you need a cuttings blowing pump to blow the drill cuttings and waste produced by centrifuge from a collection place in the site to a drill waste storage tank or directly to a transferred truck or boat, they called it ”bulk tank”. Then Screw conveyors are used to transport drill cuttings and centrifuge waste from one location on the rig to another, probably to a vertical cutting dryer in the drilling waste management system.

2 Storage of drill cuttings

A Drilling Waste Container is to storage drill cutting, centrifuge waste and pit cleaning wastes generated during drilling operations. The drilling waste containers are typically transported to a treatment and disposal site for further processing.

After the drilling waste is treated by vertical cutting dryer, the cuttings will be collected by a small waste container and be transported to other place, the fluids are pumped to high speed decanter centrifuge for further process.

Workover is used to refer to any kind of oil well intervention involving invasive techniques, such as wireline, coiled tubing or snubbing. More specifically though, it will refer to the expensive process of pulling and replacing a completion.

workover parts

workover parts

Workover Rig is available for both onshore as well as offshore. Before any workover, the well must first be killed. Since workovers are long planned in advance, there would be much time to plan the well kill and so the reverse circulation would be common. The intense nature of this operation often requires no less than the capabilities of a drilling rig.

Workover parts may include the following parts basically:

Workover rig, Manifold, triplex mud pump, mud system, BOP, Top drives, Blow out preventers.

Workover mud system:

GN solids control produced workover mud system for 250HP, 350HP, 450HP, 550HP, 650HP,750HP workover rigs. They have been applied in more than 60 countries in the world. Some clients may get the mud system from rig package supplier. But a much sane choice is to buy the mud system separately from solid scontrol Continue reading »
