OSSO nets North Sea win with Neptune Energy

OSSO, the specialist fluid temperature control and separation solutions provider, has been awarded a contract by Neptune Energy to deploy its high volume mud cooler and AutoCUL technology.
Destined for the Seagull campaign in the UK Central North Sea, the technology will allow the operator to manage the field’s high bottom hole temperatures.
The Seagull development has one of the North Sea’s highest downhole circulation temperatures, making drilling very challenging due to reduced lifespan and accuracy of downhole drilling and logging tools.
By cooling the drilling fluid, the operator can avoid delays and reduce trips out of hole, which add both time and costs to operations thus reducing efficiency.
AutoCUL will enable Neptune Energy to actively manage the mud cooler usage and downhole temperature to preserve tool life as the technology maintains a consistent mud temperature.
This prevents any risk of overcooling the mud system, which in turn eliminates the risk of thermal fracturing in the well which can cause costly delays.
John Dick, business development director at OSSO, said: “Downhole drilling on a project such as this is no mean feat. This is one of the North Sea’s major high pressure and high temperature projects and we’ve seen a lot more of these over the years as engineering has advanced, enabling enhanced reservoir production.
“We understand that the cooling of drilling fluid is an essential operational and safety priority when it comes to drilling high pressure/high temperature wells. This is why we have redesigned our mud cooling technology to reduce these burdens and costly delays.”
Alexandra Thomas, UK managing director at Neptune Energy, added: “The exciting Seagull project supports Neptune’s growth ambitions for the UKCS and is expected to produce 50,000 boe per day (gross), making a significant contribution to both UK MER and energy security, as well as supporting local supply chains.”
