Prdocution / Plugging Screen Test (PST) Guidelines

The 6 1/8” section is drilled as high slanted 84º in lower reservoir to get more exposure with production zone. After drilling, pressure points were taken to design completion fluid along with roller reamer to make sure hole is smooth. Production / plugging screen test (PST) is performed for the Reservoir Drilling Fluid (RDIF) prior to run ICD (Inflow Control Device) screens to make sure that, solids present in RDIF should not plug screens.

MUD CLEANER IN WEIGHT DRILLING FLUID

A mud cleaner is a combination of desanders and/or desilters to remove drilled solids from mud. [source]

Criticality Testing of Shale Shaker (3)

As a result of differences in the design of shale shakers and front hoods/enclosures, it was difficult to test all shakers within the exact same parameters. It was determined that each shaker had to be tested as dictated by the differences in design of each unit (Fig. 10).

Criticality Testing of Shale Shaker (2)

Drilling operations are highly dependent upon reliable shale shaker to perform efficient drilling operations. Suitable drilling fluid quality, efficient solids removal and low waste production, as well as health, safety and environment (HSE), especially of working environment (WE) in the shaker room, are all respects relevant for selection and skills operation of shale shaker in the oil industry.
