Drilling, Completions & Intervention

DeepStar focused topics on Drilling Operations, Drilling Intervention & Repair and Plug & Abandoment where members share their experiences and data to improve deep water drilling operations. 

Flow Assurance

DeepStar topic of discussions include hydrate remediation, insulated pipelines and deepwater pigging operations with the goal to assure reliable and economic production in deepwater by the appropriate design and operation through prediction, management remediation of deposition and line plugs. 

Subsea Systems Engineering

DeepStar focus is on the advancement of Subsea equipment and installation with the responsibility for analyzing existing and/or potential technology gaps and bringing them to the attention of the committee.  A secondary focus is on the advancement of long distance tieback with the goal to develop technology and qualify equipment to enable the deployment of subsea facilities for extended mile tie-backs to ultra-deep  water depth.

Floating Systems & MetOcean

DeepStar committeess role is to further technology, develop intergrity management protocols and fill gaps related to deepwater floating systems and their associated moorings and risers. While the MetOcean's goal is to improve knowledge and modeling capabilities of the circulation flow, which will provide more accurate facility design criteria and reduce downtime during deepwater drilling operations. 

DeepStar Operations

To insure that DeepStar documents and deliverable are implemented into our members companies, the operations committee confirm that field operations and corporate actively participate within the DeepStar program. 

DeepStar CORE Project Portfolio

Drilling, Completions & Intervention

Shear Ram Systems

This project will survey and document new BOP technology and capability for shearing within the industry. 


Flow Assurance

Hydrate Blockage Remediation – Electric Squid

Development of hydrate blockage remediation tool for “difficult” shaped subsea hardware e.g. trees / manifolds / jumpers. 


Measurements of Gas Hydrates Phase Equilibria

Completion fluids used in deepwater wells must be properly formulated to prevent formation of hydrates. Completion fluids could be brines or blends of brines and organic hydrate inhibitors (e.g., MEG or methanol). Reliable predictions for hydrate equilibrium conditions ae important to developing/ selecting the proper completion brine. 

Subsea Systems Engineering

Subsea Chemical Storage & Injection

Subsea production systems require both continuous and intermittent injection of chemicals to support their day to day operations. Subsea chemical storage and injection is one opportunity to reduce initial field development costs, allow additional wells to be tied in beyond what was originally planned, or to supplement the umbilical in the event it is damaged. 

Long Distance Subsea Tieback

Perform an investigation to determine how subsea production equipment and other advanced technology being developed by industry could be integrated into a subsea production system, suitable for long distance subsea tiebacks. Long distance tieback advancement for a vast range of field developments and through the use of advanced technologies, to achieve (1) Lower capital costs; (2) increased production and ultimate recovery; and, (3) improved operational flexibility and efficiencies.  

Floating Systems & MetOcean

Integrity Management of Marine Systems

Life extension / continued service for floaters is a major industry issue, with many deep water facilities approaching the end of their original design lives. While work has been completed on integrity management (IM) focused on structural issues, no guidance has been developed in IM of marine systems such as controls, ballast, safety, etc. this work will provide this missing guidance.

Low-Cost FPSO Alternative

A quest for step-change cost reduction solution via an innovative floating concept. This project will evaluate technical merits and cost comparisons of a simpler FPSO hull concept that offers multiple development options at lower costs.  

Improving Mooring Reliability & Better Standards

Improve reliability of mooring systems and prevent multi-line failures through improved Standards. Develop codes and standards to close critical gaps. 

Riser Continued Service

Evaluate fitness of existing risers and capability of current in-situ inspection methods; develop a process to safely maximize the use of existing riser systems.
