In recent years, the as the demand for environment protection is becoming more and more important, in some countries, there were even conflicts between the local residents and the oil companies or drilling companies. Companies would like to pay money on the disposal of the drilling cuttings, or, they have to face penalty even larger than the cost paid on the drilling waste management solutions.

The drilling waste management solutions for the oil and gas drilling could be divided into 2 groups: the treatment for the drilling cuttings and the treatment for the drilling fluids, the old mud.

The solution suppliers are bringing out several solutions for each group of drilling waste management, for example, in order to treat the old mud, there are several different ways, and among those, the decanter centrifuge and filter press are most prominent 2.

What they have in common?

Both of decanter centrifuge and the filter press need some chemicals to do the job, to separate out the extra fine particles from the drilling fluid.

What are the differences?

The decanter centrifuge uses the high G force generated by high speed rotating of the bowl to separate the solids from the liquid, while the filter press’ working principal is to squeeze the liquid from the solids through some filter with small holes and make the solids phase into a cake.

How are their performances?

Per their treating result, both solutions could treat out 90% solids from the liquid, especially the decanter centrifuge, the percentage is up to 95%. But when take the total cost into consideration the decanter centrifuge clearly wins out because: 1. The centrifuge uses less water than filter press. 2. Less electricity consumption. 3. Less manpower requested. That’s why 8 of ten end users are using decanter centrifuge.

Dewatering technology is greatly use for chemical separation of the solids phase form the liquid. By using some chemicals, the fine particles of solids flocculate into larger ones and to be separated out from the liquid phase. Take the oil and gas drilling mud industry as example, there are 2 main methods to be used, the dewatering centrifuge and the filter press. Seen from their outlook and working principle, they are quite different, but which to choose and why to choose is not only based on the first look, we need a detailed calculation.

  1. Purchasing cost. The cost for buying each of them is no much different, and also comparing with future consumption, this cost seems less important.
  2. The chemicals consumed: because of the high speed and high G force of the decanter centrifuge, no much chemical is needed. But in case of filter press, more chemicals in need for fulfil the work.
  3. Water usage amount: the decanter centrifuge need to be flushed only after continuous operating and the water consumption for each time is 3-4 cbm per day, but the filter press need to be flushed all over after usage, need around 150 cbm per day. In some water scarce place, this factor has to be taken into consideration.
  4. Human force needed: it is not a heavy work to operate or observe the operation of the decanter centrifuge, so one person for one centrifuge is enough. In case when several centrifuges are at same place, even one operator can work for them all. But in case of filter press, one filter press need at least 2 persons to run it.
  5. Spare parts: the spare parts for decanter centrifuge is less than the filter press.

Days and nights ago, GN Solids Control cooperated with an outdoor workforce and held an activity with suburb Beijing for a at some point journey. GN sales team gone to this journey and the quest was fruitful and substantial.
Marketing department is a very essential department of GN firm, this department is put together by more than twenty childhood who have a same objective and dream. This division includes three teams, the actual domestic sales team, the oversea market sales team and the marketing and advertising team, their duty isn’t only to get orders for the corporation, but also to collect information on the industry, receive feedbacks along with tips from clients and in addition takes some responsibility for that after sale service to the clients. Most of their period is spent on work.
Yet work shouldn’t be the just content of their life, and also work is also fun. GN Solids Control’s products are released to more than 60 nations and regions in the world, as well as for every time zone, there are GN’s clients. GN solids control has department offices and companies with USA and Russia and also GN agents are in a lot of countries. So GN income are working per different timezones and always on business holiday out of the country or from the city. It is not easy to get a re-union for everyone. GN can provide mud mixing system , mud cleaner, shale shaker , decanter centrifuge, mud agitator, mud tank ,shear pump, shaker screens ,etc.
This time, when we acquired this journey, there are still seven members are absent. GN team sent greetings photos to them to share the joy.

With this journey, there are several activities assemble, it is not only test and contend for everyone’s IQ and also EQ, but also, a challenge with regard to everyone’s courage and staff work attitude. All challenges required a good team perform and cooperation. When we are only, we can not finish some of them, even without thinking of it. Nevertheless we work together, we confront the same problem and we provide for the solution, we accomplished all of them.
It’s just like the daily do the job, when we get together and discuss our ideas and experience, it would be easier for us for the most powerful solution and make the full using our resources. Only this way, could our team be more robust and tougher.
Well done, and we’ll do better.

New environmental regulations are more focusing on the final disposal of drilling waste cutting. Normally there are several methods for final treatment of the drilling waste management . Cuttings Re-injection is also one of the main methods. In many developed countries like USA, Canada and Germany, cuttings re-injection technology is already very mature. China drillers are now more and more adopting this technology for final treatment on drilling cuttings.

Cuttings Re-injection system is always including 3 parts as cuttings transferring, cuttings screening and Cuttings Re-injection. In the first stage for cuttings transferring, there are shale shakers, centrifuge and other traditional solids control equipment doing the same job for drilling fluids recycling. The cuttings discharged from the shale shaker will be collected by the screw conveyor and then transferred to a Venturi device to fast transferring to the storage tank. Here the centrifugal pump will be equipped for shearing the cuttings. In mud mixing system, a fine mesh screen shaker will be here for screening the cuttings suitable for re-injection to underground. The injection pump is triplex cylinder type with pressure around 40MPa. With cuttings fed by the centrifugal pump, the injection pump would pump the cuttings back to the underground via the well.

160520ContainerCuttingsDryer

The well for re-injection could be either a new drilled one or an old well. Always a new one would be better to avoid the cuttings leak into the oil production layer. The re-injection layer could be under or above the production layer. This technology requests accurately analysis on the geological condition as not everywhere could be chosen as a point for cuttings re-injection.

Driller need choose the cuttings disposal method according to specific condition. Cuttings re-injection is a very good method for offshore drilling cuttings disposal, as it will save much time on shipping the cuttings back to onshore plant for treatment. Especially the application of SBM makes the base liquid is biodegradable for better environmental protection.
