6 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.
