GN Drill Cuttings Solidification Unit to Africa

Increase your environmental friendly drilling efficiency with GN Solids Control  products, one of the most important equipment is the Solidification / Stabilisation unit. The drill cuttings solidification unit is advanced and unique, which is quite flexible comparing the waste cuttings solidification plants.

Solidi cation – Is an absorption process where contaminants, typically oils, are taken into the absorbent material in the same way a sponge takes on water. In general, solidi cation is the addition of absorbents such as soil,  y ash, kiln dust, cement, clays or sawdust to the drilling waste management . The solidi ed product will have improved properties such as strength, compressibility and a reduced permeability.

Stabilisation – Is an adsorption process whereby contaminents are electrochemically bonded to the stabilising agents. Contaminants that are stabilised within the matrix are less likely to be released into the environment. This process is particularly relevant to the stabilisation of heavy metals and oils that would otherwise be rapidly available to the environment through leaching.

The adeptness to coalesce or stabilise a accurate decay beck and the e ectiveness of the analysis is abased on the decay blazon and analysis reagent factors. Typically, adumbrative samples of the decay are class activated to actuate the a lot of acceptable conception above-mentioned to eld implementation. Selection of the conception is commonly based on key belief such as leachate superior and backbone of the nal product.

Solidi cation and stabilisation generally requires the use of specialised accessories and actinic reagents. The processes absorb signi deceit abstracts administration upstream and after of the bond unit. Some decay streams may accommodate contaminants that can arrest the solidi cation/stabilisation processes.

For the solidication / stabilisation action to yield abode it is important to carefully adviser the decay produced at the rigsite for levels of alkali baptize and oil. This will advice to minimise the use of reagents and optimise the process, thereby abbreviation costs and the ecology impact.

Thus, it is with the accomplishment and ability that Scomi Oiltools has developed over the endure 20 years that allows us to, accommodate safe, amount e ective and environmentally complete solidi cation and stabilisation processes.

Why The Drilling Waste Should Be Treated or Handled

Where is a well being drilled, where is the waste generated. The wastes generated by drilling vary from the drilling fluids used for drilling and the drilling site, but generally include drilling cuttings, waste water, spent drilling fluids, completion fluids and filtration wastes. Absolutely the wastes are contaminants to the surrounding ground and water if directly buried in the mud pit. With increasing public awareness of the damage caused by the wastes, the stricter environmental standards and regulations on drilling activities, the significance of the handling and treatment of has attracted the eyes of drilling contractors and increased in different degrees around the world.

The handling and treatment process depends largely on the local regulation of a country, while in a country where there is no environmental regulation on the drilling activities, the drilling contractor will fall back on minimum standards used in other countries or standards set at a corporate level. Generally, 4Rs can be used to describe the process of handling and treatment of the drilling wastes: Reduce&Reuse&Recycle&Recover. Reduce means reducing the wastes by some methods such as precise plan, smaller bole and selection of drilling fluids. It would be perfect if no waste generated when a well is drilled. Reuse means cleaning the waste to collect active drilling fluids by solids control equipment normally including shale shaker as 1^st phase, desander& desilter or mud cleaner as 2^nd and 3^rd phases, and decanter centrifuge as the final phase. Recycle means to further treat the drilling cuttings after Recycle after the recovery of  the drilling fluid for reuse. Recover means to make the drilling cuttings into a hydrocarbon by high temperature treatment. Though the recovered hydrocarbon can not be used as drilling fluids, it can be used for a fuel material.  

GN Decanter Centrifuge is applying within the offshore

As GN Solids Control keeps supplying excellent solids control and drilling waste management systems to worldwide clients, increasingly more GN devices for example shale shakers, desanders, desilters, mud cleansers, decanter centrifuges and vertical cuttings dryers etc.

Lately, GN supplied one decanter centrifuge for that American offshore drilling rig. As everyone knows, the drilling rigs that utilized on the offshore also have a strict requirement for the solids control devices. Once they looked for many producers who are able to manufacture decanter centrifuge, finally they chose GN decanter centrifuge due to the superb working performance, very long time usage without damaged and be assured service.

This offshore drilling rig is applying 2 sets centrifuges: Baker Hughes provided some decanter centrifuge on their behalf, so we provided another decanter centrifuge via our partner. Really, we've provided four sets decanter centrifuges and cuttings dryers to Baker Hughes in Russia, and working well under the cold temperature.

For that centrifuge we found here is one variable speed decanter centrifuge with VFD control panel. GN centrifuge and Baker Hughes centrifuge work together to complete solids separation work.

GN sent experienced engineers for service once the customer bought this centrifuge from us. Because of the significant working room is fairly small GN decanter centrifuge met some troubles on feeding drilling liquids. The pump is too far for the decanter centrifuge, and also the pump must feed drilling liquids right into a quite greater positive than normal. To create factor worse, the feeding pipe from the pump needs to go ahead and take working room into account, so many curves from the pipe that are either produced by the steel pipe or even the rubber pipe. It’s a bit hard to feed the centrifuge because of so many curves.

However, GN decanter centrifuge is working well in customer’s offshore worksite.

GN Vertical Cutting Dryer utilized in Russian Project

Hebei GN Solids Control Co., Ltd is the first API manufacturer of drilling waste management equipment and system in China. Inside a complete GN drilling waste management system, you will see 2 stages treating equipment. The first is vertical cutting dryer which is often used to dry the solids released (mainly waste cuttings) from shale shaker, desander, desilter or even the mud cleaner using the mixture of desander and desilter, and so the solids is going to be dry enough as needed through the environment rules to become disposed. The liquid is going to be delivered to the second stage treatment equipment: decanter centrifuge for more processing to split up ultra-fine solids out, and also the liquid is going to be collected or moved towards the active tank for recycling usage.

This past year, GN offered 4 group of drilling waste management system to Russia, and they will operate as planned even during the cold months with temperature below minus 20 levels. This type of system includes GNCD930 vertical cutting dryer because the first stage treatment equipment as pointed out within the first passage, and something GNLW363BG-VFD decanter centrifuge because the second stage dealing with equipment as referred to within the first paragraph. The liquid after decanter centrifuge is going to be shipped towards the recycling tank for recycling usage, and also the cuttings released in the vertical cutting dryer is going to be with 3%-5% oil content.

As everyone knows how large the part gas and oil play in Russian economy, though seriously shocked through the continuous lowing oil cost, Russia has the ability to feel the crisis. GN drilling waste management will begin operating as planned, and GN after-sales has done the commissioning to make certain scalping strategies can function normally and securely, also to make GN machine works best based on the drilling waste conditions.
