The importance of the casing shoe is often overlooked, but as it lies at the very start of a drilling job, its reliability is of prime importance. Premier shoes are designed to be robust enough to withstand the rigours of advancing the casing through changing overburden conditions and into bedrock: they are reinforced with carbide on both the inside and outside gauges – a feature not shared by every competitor. Premier shoes have been rationalized to one standard, all units having a Vee-ring profile and full reinforcement including a diamond set outside gauge for reliable, consistent results.
