Nomacs movement4/2/2023 Reducing rig mobilization time has become increasingly important to operators as drilling times become shorter and shorter. Some would argue that if a rig has a big top drive, big mud pumps, a walking system and fast-moving capabilities, its performance will depend primarily on crew strength, not whether it is an AC or SCR rig. However, there’s a large segment of operators who will pick up, perhaps even prefer, an SCR rig that has been upgraded to tier-1 specifications. Many operators don’t care to discuss anything but an AC rig, which is fine. Rather, the next cycle of innovation will either be in downhole tools, control systems or the way those two interact.ĭo you see operators significantly preferring the tier 1 advanced-technology rigs over the older rigs? Additionally, land rigs will continue to be populated with ancillary mechanized equipment like iron roughnecks, hydraulic catwalks, BOP handling systems and pipe-handling machines.įor these tier 1 rigs and properly upgraded tier 2s, I don’t necessarily see another equipment step-change in the near future. Virtually all of today’s newer tier 1 rigs and recently upgraded tier 2 rigs address the three key areas needed to develop the resource plays: 1) higher-horsepower mud pumps, 2) higher-torque top drives and 3) fast moving capabilities. In addition, we’re also disposing of several low-tier mechanical rigs. We will continue upgrading our SCR rigs, investing approximately $25 million this year to improve these rigs to modern shale-suitable specifications. We are currently in the midst of a 12-rig, all-AC newbuild program, with four already delivered and eight more to be delivered between January and June of 2013. Nomac, like many other contractors, has adopted a simple fleet upgrade strategy: newbuilds at the top, upgrades in the middle and divestiture at the bottom. Are there any specific areas of rig technology/equipment in which Nomac is working to push past the limits of today’s rigs? ![]() Operators continue to look for improvements in rig technology and equipment above and beyond the mobile, high-horsepower and mechanized rigs that contractors have today in order to help them to reduce spud-to-spud time and improve performance.
