The following key tasks are very important during drilling process :

• To take out the claws out of the well
• To cool mats
• To prevent collapse of the well wall
• To balance the formation pressure
• To lubricate the drilling pipes, walls of the well, the retaining pipes
• To keep crumbs and sand particles suspended, prevent accumulation in wells, if drilling is stopped
• To prevent rusting
• To lighten the weight of the storage pipes and drilling pipes.

Bentonite mud, which has to fulfil the functions indicated above, is essential for drilling economics due to its low cost. The amount of bentonite used in the drilling mud depends on the depth of the well, its diameter, the characteristics of the formation, sludge leaks, etc.

One of the factors that increase the cost of the mud is the treatment of the water bentonite mixture, since the amount of added chemical substances is directly related to the physical properties of the bentonite.

Key advantages of ANEDM Bentonite:

• ANEDM Bentonite keeps the bumps in the drilling mud suspended due to its high viscosity and gel-making property, thus it prevents formation of fractures in the well and trapping the drill.
• ANEDM Bentonite provides effective well cleansing by reducing the shear rates of formation sections within the drilling mud.
• ANEDM Bentonite provides well immobilization (permanence) by forming a solid and smooth plaster in the well wall with its high plastering property.
• ANEDM Bentonite performs a proper lubrication function in the well, drill and drilling line due to its slippery property.
• ANEDM Bentonite prevents the penetration of gas and fluids which may cause formation into the well.
• ANEDM Bentonite prevents rusting which can occur on drilling and drilling sequences.
• ANEDM Bentonite ensures that aggravating substances in the drilling mud are retained in suspension as preventing water leaks.
