?Schlumberger has introduced the PowerDrive Archer high build-rate rotary steerable system (RSS). According to the company, the new system has delivered high build rates in many formations from any inclination and in a single shoe-to-shoe run with no flat time for trips to change the bottomhole assembly. High build rates allow deep kickoffs to place more of the well bore in the reservoir, maximizing drainage capability.

The new system can maintain verticality even in high-dipping formations. In horizontal sections, it can drill through hard, interbedded formations at high angles of incidence. The hybrid steering system allows sidetracking from an open hole at any point. All external parts on the RSS rotate – a feature that reduces the risk of mechanical or differential sticking and improves wellbore quality for easier well completion.

The PowerDrive Archer RSS delivers well profiles previously possible only with motors yet with the ROP and wellbore quality of a fully rotating RSS. The system does more than execute complex 3-D wells in one run – it also increases potential for hydrocarbon production. www.slb.com/archer
