One of the biggest challenges of providing engineered oil and gas drilling tools is the
necessary combination of innovation and standardization, such as mud cap drilling. Components and
tools need to “fit the mold” in order to be compatible with current technology and ensure usability by workers.
However, they also need to be flexible in their design so they can be adapted to changing and potentially extreme

The below mud cap drilling case study is an excellent example of the
powerful problem-solving potential of our products. Drilling Innovative Solutions is proud of what we accomplish for
our clients. We always look for ways to effectively address the challenges of each project, whether they are
logistical, technological or geological.

Delving into the Austin Chalk

This project was the first for the operator as well as the first job to utilize the
Sentinel Drilling Safety Float Valve in the
Austin Chalk. The job, which took place in West Central Louisiana, was also the first time this particular
technology was used in a mud cap drilling assignment.

Problems Presented

The client presented several key issues when they first contacted us for a drilling
solution, including numerous ongoing drilling float failures with at least one that had the potential to cause a
well control issue. Based on this information, it was evident that the client needed a unique solution that would
yield reliable performance as quickly as possible.

Our Solutions

The team at DIS was able to meet the logistical needs of the project by beginning tool
deployment immediately, which allowed the equipment to reach the site the same day as requested. Once the
utilization of our
Sentinel 475 DSFVs began, our client was
able to complete the drilling process without any more service interruptions related to failures in safety float

About the Drilling Technology

The beauty of a well-designed piece of equipment is that it doesn’t have to be large or
elaborate, it just has to work. The
Sentinel Drilling Safety Float Valve is not
a large piece of technology, but it produces substantial results for our clients. It’s one of our primary product
lines and we consider it a revolutionary development that can have a big impact on performance and overall costs. It
was designed to overcome some of the key issues with previous float valve technology, particularly their inability
to hold up for long-term use in extreme conditions.

The Sentinel relies on our field-tested flapper actuated ball technology and can
maintain a proper seal even under harsh downhole drilling conditions. It has proven to be a reliable solution for
use in Underbalanced Drilling, Managed Pressure Drilling (MPD) and Directional Drilling operations. It is also
outfitted to serve as an effective barrier against well control events.

All of our drilling safety float valves are made to meet the highest ISO 9000 and API
standards to ensure quality. The valves are designed for high-pressure environments up to 10,000 psi and
temperatures as high as 450 degrees Fahrenheit, which makes it a suitable choice for HTHP conditions. They are also
available with several customizable elements upon request, including non-standard connections and sour gas condition

Leverage Innovation for Better Performance with DIS

Our experience drilling in the Austin Chalk illustrates the importance of using the
right tool for the job. Saving time, money and resources, the
Sentinel Drilling Safety Float Valve was
able to serve the specific needs of our client. We look forward to the opportunities and challenges presented by
each of our clients and working to provide the optimum solution.
