Drilling fluid shale shaker is the primary processing equipment in solids control system, used for separating larger cuttings from drilling mud, and it plays an important role in protecting drilling fluid performance.

Design Procedure of Shale Shaker

1 Shale shakers skids shall be level.

2 Shakers shall be rigged with adequate space, walkways and handrails to permit easy and safe servicing.

3 if the shaker is equipped with a rear tank, the flow line shall enter the rear tank as near the bottom as possible.

4 A means of diverting fluid from the flow line is recommended to permit the disposal of cement, spotting fluids, contaminated fluids, etc, before these fluids reach the shale shaker. The procedure shall not be used to dump the rear tank into the sand trap before trips.
 

Operation Procedure of Shale Shaker

1 The screens shall be inspected every time circulation is interrupted.

2 Use the shaker screens with the smallest openings that do not cause excessive drilling fluid loss.

3 Under normal operating conditions and when using a single-deck shaker with multiple screens, all screens shall have the same API designation.

4 Torn or damaged screens shall be replaced or repaired promptly.

5 When using shaker screens that need tensioning, tension shall be checked 15 min to 30 min after installation and tourly thereafter.

6 All fluid, including that shipped to the rig from elsewhere, shall be screened before entering the active system tanks. The larger the screen area is, the better the screened effect is.

7 Screen selection with weighted drilling fluids involves a compromise to accommodate the need to maximise cuttings removal while not separating excessive quantities of weighting material. Usually an API 200 is the limit of the finest shaker screen that does not remove excessive quantities of weighting material (¡.e., barite).
