Drilling Rig Construction Case Studies
Transocean is a Swiss offshore drilling company that provides rig-based well construction services worldwide. The company is one of the largest contractors in its sector and has offices in 20 countries. It operates a fleet of versatile, mobile, offshore units comprised of midwater, deep water, ultra-deep water, and. . Oil and gas drilling rigs are very complex systems that contain thousands of processes which must operate 24 hours a day in remote environments and harsh weather conditions.. . The well optimization simulation model was a proof-of-concept project, and the comparison of the real-world well construction cases and the virtual predictions showed a. . Transocean decided to begin with a proof-of-concept project and to continue development if it showed satisfactory results. The company chose AnyLogic as the platform for their simulation for several reasons, including AnyLogic’s multimethod simulation modeling. [pdf]FAQS about Drilling Rig Construction Case Studies
What are oil and gas drilling rigs?
Oil and gas drilling rigs are very complex systems that contain thousands of processes which must operate 24 hours a day in remote environments and harsh weather conditions. New drilling rig construction can require more than a billion dollars of investment.
How much does it cost to build a new drilling rig?
New drilling rig construction can require more than a billion dollars of investment. The process has lots of interdependencies and there are many different failures that can occur. As a result, the operational and financial characteristics of a system during setup and production are often difficult to predict.
What is a ConocoPhillips rig?
The rig would address requirements from ConocoPhillips, Alaska to improve recovery in the existing oil fields on the North Slope. Harlan and Shawn Smith worked collaboratively with the client, Nabors Drilling, to develop a new rig design that would significantly improve coiled tubing methods and efficiencies on the North Slope.
Can pre-drill Engineering improve drilling performance?
Abstract This paper presents a case study for improving drilling performance by maximizing penetration rate while ensuring that hole conditions are not compromised. The overall aim was to identify and prevent invisible lost time (ILT) and nonproductive time (NPT) by means of pre-drill engineering studies and real-time drilling optimization.
What is a coiled tubing rig?
The unique coiled tubing rig allowed a single rig to support the drilling and completion of up to 8 laterals from a single well bore. In 2015, Entro received a contract to design and fabricate a sister rig to CDR2 for Nabors Drilling designated CDR3.
How do we determine potential areas of improvement during drilling?
During the actual drilling of the wells, potential areas of improvement were determined by analyzing MSE and evaluating ILT/NPT. Real-time MSE analysis was conducted during drilling operations to adjust parameters to increase ROP performance.

Double rod rock drill
Before diving into whether or not you should invest in a dual-rod machine, you need to know a little bit about the technology and its advantages for drilling in rock. “Dual-rod systems use two independently controlled drill rods— one within the other — during operation,” explained Michael. “While drilling out the pilot. . One of the first factors to consider before choosing a dual-rod machine is the type of rock you’re working in. “Dual-rod drills are efficient in light- and. . For most utility HDD work, small jobsites and the ability to quickly set up and tear down are essential to a crew’s operating efficiency. “Dual-rod machines can often be transported on. . As you can see, the decision to add a dual-rod machine if more than 50% of your work is in rock, or to add a single-rod machine if less than 25% of your work is in rock, is pretty straightforward. However, if you fall someplace in the middle, then you have a lot to. . Of course, how long a bore takes can often depend on the operator’s skills running the drill. Michael said the operator’s capabilities on the drill is another critical factor to consider when deciding between a single-rod and a dual-rod machine.. [pdf]
