Saudi Aramco and the National Shipping Company of Saudi Arabia (Bahri) have amended an expired memorandum of understanding (MOU) on developing a maritime complex that would provide engineering, manufacturing and repair services for offshore rigs, commercial vessels and offshore service vessels in Saudi Arabia.

New-design rotary steerable systems target higher doglegs, durability in high-temperature reservoirs, autonomous steering

As operators hunt for reserves in plays with increasingly high pressures and temperatures and where high-dogleg well profiles are needed to access sweet spots, the cost of drilling has continued to grow. To reverse that cost trend, oilfield service companies are working to design and build more reliable and higher-performing rotary steerable systems (RSS). “What we’ve seen here, specifically in the North American land market, is the drive toward factory drilling and automation to decrease costs and an increased focus on improving the quality of wellbore placement to increase reserves,” said Steve Krase, Director of Wellbore Placement at Nabors Drilling Solutions.

Flow loop testing verifies adaptive model-based choke control system

Managed pressure drilling (MPD) is a technology that enables fast and precise control of the pressure in the well during drilling and completion operations. This is achieved by sealing the annulus and diverting the return flow through a choke manifold. By opening or closing the chokes, one can actively control the backpressure and, indirectly, the pressure at a desired location in the well.

Perspectives: Erin Welsh, Seadrill: Offshore work is not a career stepping stone but provides valuable opportunities for hands-on work, making real changes

For Erin Welsh, Technical Superintendent-Well Control Equipment at Seadrill, what started as a stepping stone became the foundation for a career. She attended the Colorado School of Mines starting in 1992 and majored in engineering, with a specialty in mechanical engineering. Her intention was to design equipment.

Data acquisition capabilities, durability enhanced in new crop of coiled-tubing, intervention tools

The need to keep pace with the increasingly long laterals that operators are drilling remains a driver for R&D efforts around well intervention and coiled tubing (CT). However, in the current price environment, that innovation must be coupled with the ability to lower costs. New CT and intervention technologies appear to be achieving such cost reductions by increasing equipment durability, which results in fewer trips out for replacement. In addition, more real-time data collection is being used to make real-time adjustments to maximize efficiency.

After mechanization and automation, industry now looks to robotics

In the oilfield’s steady advance toward a largely robotic-driven drill floor, the profound influence of inter-industry technology transfer is undeniable. As demonstrated during the development of robotic technologies for repetitive and hazardous rig floor activities, robots employed in outside industrial settings provide sound baselines for adaption to meet drilling requirements.

From the President: As drilling contractors’ association, IADC will focus on listening to, responding to members’ needs

These are trying times for our industry. Last year was a difficult year, and this year’s forecast is equally as challenging. We have seen the effects of the depressed market reflected in the reduction of rig counts and companies who have shuttered their operations. People are comparing this downturn to the one of the mid-1980s, a time we all hoped never to revisit.

Beyond ROP: Industry taking systems view to drilling optimization

Optimized drilling once meant drilling farther and faster to achieve high rates of penetration (ROP) using efficient, cutting-edge technologies and approaches like pad drilling. Today, with oil prices remaining low, that need for speed has given way to a more balanced approach, with operators taking a step back and a wider view of downhole drilling optimization.
