Oil and gas company ORLEN Upstream, a subsidiary of PKN ORLEN, the largest crude oil refining company in Poland, successfully drilled a horizontal shale well using TenarisHydril Wedge 563™ premium connections. The operator took on the challenge of drilling the Stoczek-OU1K well to analyse the gas accumulation and producing capability of the Lower Silurian and Ordovician shale deposits.

The TenarisHydril Wedge 563™ premium connection was chosen for the production casing string. This technology offers extreme torque resistance as well as field-proven performance. It easy to handle and run, and ensures 100% ratings in tension and compression. The connection came with the Recess Free Bore (RFB) option to facilitate the undisturbed flow in the well during the fracturing process. To reduce the frictional forces, which occur while running the string into the lateral part of the well, the coupling with special bevel was utilized. 

The result was a smooth operation with zero re-makeups and rejects due to product-related matters. ORLEN Upstream was satisfied with the connection performance and acknowledged that TenarisHydril Wedge 563™ connections were instrumental to reach the target depth.

Tenaris technical sales and field services teams worked side-by-side the customer to ensure the success of the operation. The expertise of Tenaris technical sales team supported ORLEN Upstream in finding the best solution to overcome the challenges posed by the Stoczek-OU1K well. The field service specialist was present on the site to share knowledge and experience, providing useful advice whenever the customer required.
