Solids build up is one of the main concerns that causes ROP reduction and changes mud properties during drilling. This also becomes a serious problem in the reservoir section due to the potential formation damage which in turn results in reduced hydrocarbon production. High performance solids control can remove solids up to 5 micron which can improve mud properties and drilling performance.

• Decanter centrifuges.
• Centrifugal pumps.

We provide Barite recovery systems onsite and we pair two centrifuges together, in which the first centrifuge targets solids between a 10 and 100μm range and the second purportedly removes those solids less than 10μm.
This 10 and 100μm range is the sweet spot within the particle size distribution curve for barite as highlighted below. The lower end of this range (10μm) is set by the centrifuge’s applied G-force, where the upper end of this range (100μm) is set by the practical suspended solids cut achieved by the primary solids control system, the flow line shakers.

The main purpose of barite recovery system is to:

•  Reduce the content of drilled fines, specifically colloidal solids, and
•  Perform barite recovery in order to reduce drilling fluid additive costs.

The lower end of this range (10μm) is set by the centrifuge’s applied G-force, where the upper end of this range (100μm) is set by the practical suspended solids cut achieved by the primary solids control system, the flow line shakers. The influent to the barite recovery centrifuge comes as a “slip-stream” from the active mud system. This
means that the full circulation volume of the Active Mud System is not sent through the centrifuge system. The first centrifuge’s solids “cake” is returned to the Active Mud System with the goal of recycling barite, where the centrate (containing the colloidal and ultrafine solids) is plumbed to the second centrifuge.

The second centrifuge is configured as a high-speed centrifuge to remove low gravity solids. The target range rests between the maximum capability of the centrifuge, relative to the maximum achievable G-force that can be applied (typically 2 to 5μm), and the lower range defined by the barite recovery centrifuge. The solids “cake” is considered waste and is disposed of, whereas the “cleaned” centrate is returned to the Active Mud System.
