No room for failure in RSS performance as cost pressures persist

NOV developed the VectorEDGE RSS for drilling lateral sections in wells on well-understood fields. By eliminating near-bit sensors and built-in MWD equipment, the cost of the RSS has been cut in half. Design of the system began in 2012, and field tests in West Texas and the Northeast US have been ongoing since 2016.

Today’s rotary steerable systems (RSS) are being developed with one primary goal: delivering high-quality wellbores at low cost. Some service companies are reducing costs by developing more durable tools that can drill for longer in harsh environments, while others are focused on reducing the cost of the tool itself by eliminating non-essential functions...

North Sea wells prove efficiency, function of multistage ball-actuated, sleeve-based stimulation system

Packers and sliding sleeves on the inner liner allow for staged fractured operations inside the perforated outer liner.

Wells in the North Sea that require multistage fracturing have typically used cemented plug-and-perf completions. Although this method is widely used due to historical precedent, its stimulation effects can sometimes underdeliver. The process is also time consuming, with typical turnaround times per stage varying from three to seven days for North Sea projects...

Statoil adopts integrated, trilateral partnership in search of ‘perfect wells’ on Johan Sverdrup field

Speaking at the 2017 OTC on 3 May in Houston, Jákup Øregaard, Drilling Manager at Statoil, detailed an integrated, trilateral partnership among the operator, drilling contractor and main service provider, including a shared incentive system, that supported a 70% recovery goal for the Johan Sverdrup field.

Operated by Statoil, Johan Sverdrup is one of the five largest oil fields on the Norwegian Continental Shelf (NCS), holding an estimated 1.9 billion to 3 billion BOE. In March 2016, Statoil began pre-drilling eight producer wells on the field, with the goal of delivering “perfect wells,” or wells delivered in the minimum possible time, that would contribute to a 70% recovery goal for the field...
