The most time consuming operation in drilling is the lowering and pulling of the drill string. Especially in the deep holes and in broken formations where core blocking exists , this operation decreases penetration rate very sharply and also causes caves and stuck rod problems. Wireline equipment has been innovated to overcome these problems and has started to replace the conventional drill strings.

Polmak manufactures high quality wireline equipment incorporating the properties of the latest technology. HO , NO , BO and AO core barrels and overshots , the types of these core barrels for highly deviated hole drilling (upper and horizontal) with all auxiliary equipment needed are within Polmak’s standard production and can be supplied from stock. For wear resistance , wireline rods and core barrel tubes are chrome plated at our own promises.

PO size wireline drill rods and core barrels are available upon request.
