OBS-2 Bow Spring Centralizer
The OBS-2 is our most cost competitive single piece, bow spring centralizer. It has been developed for onshore vertical, horizontal or deviated wells with build rates of less than 10O /100’ and horizontal sections less than 10,000 ft.
The OBS-2 is compliant with the API 10D standard. Its single piece construction provides strength downhole, while the proprietary heat treatment process makes the bows highly flexible.
The OBS-2 unit is shorter compared to the premium Centek S2 but maintains excellent flow by area to support of cementing best practice. And, due its smaller size, the OBS-2 can be delivered with up to 100% more product on the pallet, reducing transport and storage cost significantly.

Centralization and the ease of running casing is often a balance between strength and flexibility which combine to support, what we call, 'runability'. To help with product selection we've added a rating to all our products for flexibility, runability and inherent strength.
