Technology will become an important factor in developing resources below the ocean surface.

Sustainability is our main strategy.

Gradient Drilling Solutions (GDS) is a company focusing on solutions and systems for developing and exploiting recourses below the ocean surface in the most sustainable, cost effective and environmentally friendly way.

We develop solutions and systems for extraction of resources from the seabed in deep oceans to drilling wells to extreme depths and lengths.

Our vision:

To make subsea the most environmentally and economically sustainable method for resource exploration and extraction.

Our mission:

To radically reduce costs, risks and the environmental footprint from drilling subsea wells and resource extraction.

Oil and gas wells
CCS wells
Gas hydrates
Sea-bed mining

Technology will become an important factor in shaping the future in subsea drilling and operations
Tomorrow's winners will have to understand the underlying fundamental problems and apply the best technology in order to improve efficiency and reduce the inherent cost and risk
Pressure in the underground formations is the most important parameter deciding the risk, time and cost in drilling
Gradient Drilling process has shown to substantially improve the effectiveness for managing these parameters in subsea drilling compared to conventional processes
GDS will supply the control systems and specifications necessary for the customers to achieve these goals
It is our goal to become the preferred provider in this field and for driving atomization and digitalization of drilling operations and subsea pumping operations

RMC -Riserless Mud Circulation

CML -Controlled Mud Level

RLD -Riserless Drilling

MPC -Managed Pressure Cementing

PR-MPD -Pumped Riser MPD System

SS-MPD -Riserless Subsea MPD System

RMC -Riserless Mud Circulation

Enables operators to drill better-quality top-holes safely, deeper, faster and with far less impact to the environment
Enables the use of overbalanced and engineered drilling fluid
Volume control and early inflow detection
No discharge to sea

Shallow Water RMC System

Deepwater RMC System

RMC Control System HMI

CML - Controlled Mud Level, a managed gradient drilling method

Reduced well cost
Drill longer sections (fewer casing strings)
Faster drilling and less NPT
Minimized formation damage
Improved well productivity
Improved qualities (zonal isolation, well integrity, quality of information, etc.)
Less drilling consumables & smaller environmental footprint
Increased safety & well control
Improved kick/loss detection

RLD - A riserless open water dual gradient drilling system

Possibly the "holy grail" of drilling in harsh environment
- Exploration
- Greenfield
- Brownfield
- Slot recovery & P&A
Faster
Safer
Bigger operational window
No discharge
Less consumables and CO2 footprint
No wellhead fatigue

MPC - A Managed Pressure Cementing System

For cementing surface casings in unstable formations or where there is risk of shallow gas or shallow water flow
The system provides precise control of the pressure in the casing annulus during the cementing operation
Improving well integrity and barrier status of all types of wells

PR-MPD - a pumped riser MPD System

Faster ECD compensation when RCD installed
Closed system but same advantage as CML
- RCD run only when required
RCD not a primary barrier element
- Drilling fluid still the primary barrier
No pressure at surface
SPM independently retrievable

SS-MPD - a Riserless Subsea MPD System

Probably the best and safest MPD system for floating rigs
Drilling with overbalanced fluids using the subsea pump to reduce the wellhead pressure below that of ambient seawater pressure above the RCD
