HPHT Mud Cooler Case Study
DHMO works worldwide in the oil and gas industry, providing specialist heat transfer and mud cooling equipment to allow for safe and efficient HPHT drilling.
A recent project for an oil & gas service client, saw the successful installation of a DHMO modular hpht mud cooling system.
The Problem
When drilling HPHT wells, drilling fluids are often returned to the surface at elevated temperatures. This can:
- Present issues for BOPs
- Create an unsafe working environment in the pit room
- Result in reduced lifespan and accuracy of MWD and logging tools
- Increase the risk of explosion when drilling fluids exceed their flash point.
A long-standing client of DHMO was facing such issues.
The Solution
DHMO’s highly experienced technical team ran the necessary calculations to size a suitable system. In this case, a single cooler package was sufficient for the client’s needs.
Before mobilising, our cooler was pressure tested. Its gauge and lifting certificates were renewed and an in-depth inspection was carried out.
Subsequently, our mud cooling system was shipped to the client’s rig, taking just a couple of days to arrive and a few hours to commission, due to its modular, plug-and-play design. The entire system performed with absolute reliability for the duration of its hire.
ROI
The temporary installation of our mud cooling system resulted in rig-time savings and reduced operational costs. Health & Safety was at the forefront of this intervention; drilling fluids were maintained below their flash point, providing a safe working environment for all personnel.
DHMO recommends for all operators and service companies to consider cooling requirements as far in advance as possible of drilling HPHT wells.
