Choose the correct tricone is important during the drilling project.IADC537 is TCI journal sealed bearing bit with gauge protection for soft to medium soft formations with low compressive strength.
Rocks hardness could be not same, such as soft, medium and hard or very hard.Hardness of one type of rocks may be also not same, for example, limestone,sandstone, shale has soft limestone, medium limestone and hard limestone, medium sandstone and hard sandstone, etc.
Far Eastern have 15 years and more than 30 countries services experience to supply the drill bits and advanced drilling soulutions for many different applications. The application including oil field,natural gas,geological exploration,driectional boring,water well drilling ,The various drill bits can be customized as per different rock formation becasue we have our own API & ISO certified factory of tricone drill bits. We can give our engineer's solution when you can supply specific conditions, such as hardness of rocks,types of drilling rig,rotary speed,weight on bit and torque.
Far Eastern Drilling can offer tricone bits in a variety of sizes (from 3” to 26”) and most of IADC Codes.
