Mud tank design for solids control system is very important. The surface pits that comprise the active circulating systems should be designed to contain enough usable mud to maintain mud properties and to fill the hole during a wet trip at the rig’s maximum rated depth. Usable mud is defined as the mud volume which can be pumped before suction is lost. For example, a typical 10,000 ft well will normally require a minimum active system tank volume of 500 bbl

Tank Shape Design

To maximise solids suspension in drilling mud and usable volume, the best tank shape is round with a conical bottom. Next best is a square or rectangular shape with a v-bottom. The least preferred shape is the square or rectangular box with a flat bottom. The ideal tank depth is equal to the width or diameter of the tank. This design provides sufficient pump suction head and is best for complete stirring.

Tank Compartment Equallsation

Equalisation height between compartments will depend upon the duty of the compartment. As a rule, an adjustable equaliser is needed only between the solids removal section and the addition suction section. High equalisation between the solids removal and addition suction sections also increases the ability to detect volume changes due to influx or losses to formation. Because the volume of the solids removal section remains constant, any volume change is apparent as a liquid level change in the addition suction section only. This increases the sensitivity to volume fluctuations since the change in fluid level will be more pronounced per unit volume.

A tank design will including sand trap, equipment arrangments, etc. A tank design is very important for a complete line solids control system. Please contact GN Solids for inquiry freely

Mud Tank

Mud tank has different applications, when drilling wells, mud tank will be working to storage mud or mixing mud. A mud tank may divided into several compartment, may including difference design of pipelines, difference size, etc.

GN Solids Control for Customize Mud Tank

Normally the majority of solids control supplier offers standard mud tank and won’t accept customize design. GN Solids Control is a supplier do customize mud tank for clients. Customize mud tank including:

1)       Tank size and dimention

2)       Tank compartment divided.

3)       Pipelines inside of tank

4)       Painting color

Mud tank may working on oil&gas drilling, coal bed methan drilling, HDD drilling, diamond drilling, water well drilling, etc. Please contact us for inquiry freely

Gas Drilling solids control system aways at least 2 tanks with shale shaker, desander , desilter, centrifuge and mud tank. It will need a separate trip tank or  trip tank compartment  before sand trap for caculating or fill rig holes.

Trip Tank Dectription

Trip tank will hold mud for about 5 cubic meters or depending on different rigs and will install mud gun for transfer mud and maybe mud agitator. One or two trip pump will be needed to transfer mud to drilling hole. If you need GN build you a trip tank, the bellowing info will be needed:

1) Trip tank capacity

2) Tank size requirement

3) Your original solids control system layout and tank size with main equipment to cooperate

GN Gas Drilling Mud Cleaning Equipment other than Trip Tank

GN Solids Control is a supplier for a complete line gas drilling mud cleaning equipment incluidng shale shaker, desander desilter or mud cleaner, decanter centrifuge, centrifugal pump, mud agitator, mud gun, mud tank and related items. Shale shaker and centrifuge are the 2 most imporatant equipment, GN is able to offer separate equipment or a complete line solids control system.

Trip tank is a 7-8 cubic meter mud hold tank with trip pump beside shaker tank. Normally it’s including one mud tank, mud agitator, centrifugal pump and mud gun.

What is the trip tank do?

1. Provide sufficient hydrostatic pressure to prevent influx from reservoir. When TOH, mud hydrostatic will be lost because mud volume must substitute drill pipe volume pulled out of hole. If hydrostatic pressure decreases too much, influx from reservoir can come into the hole and make a trouble in well control. For this reason, mud in trip tank must be filled into hole to maintain hydrostatic pressure.
2. Kick Indicator: Volume of mud from the trip tank is pumped in the hole can be an indicator that relates to a situation occurring in wellbore as kick. If the volume of mud measured by trip tank is less than the expected volume of drill pipe volume tripped out of hole, the suspect problem is kick because volume of kick substitutes volume of mud.

Gas Drilling in Papua New Guinea

There are a lot of gas drilling in Papua New Guinea which will enable them to purchase drilling rigs and solids control system or equipment like shale shaker, decanter centrifuge, mud tank, centrifugal pump,etc. Origionly they like to purchase US rigs and solids control equipment, but they are trends to buy China equipment since China equipment is getting top quality with lower price.

GN Solids Control is a solids control equipment manufacture and top quality with top service all over the world. Please contact us freely for inqury
