As offshore operators get into deeper waters and develop more mature oil & gas fields using more complex well architectures, continuous downhole injection of chemicals is increasingly required to manage challenges such as scale formation or asphaltene precipitation within the wellbore…
Just as its current workload was drawing to a close, the HSM Offshore yard picked up a substantial construction contract from GDF Suez E&P Nederland for the operator's Dutch sector L5 and D18 projects. Tenders included three (two x 1200te, one x 1800te) topsides plus jackets…
The latest generation of Liqui-Cel membrane contactors on show at OTC are claimed capable of deoxygenating injection water with less weight and a smaller footprint than conventional deaeration technologies, such as vacuum towers. The compact…
Asia Pacific has become the latest happy hunting ground for Bergen-headquartered construction vessel operator DOF Subsea, which already employs 220 professionals at its project management and engineering centre in Perth, Western Australia. Well established in the North Sea and Brazil…
French offshore service provider Bourbon Subsea Services calculates that its seven inspection, maintenance and repair vessels working offshore West Africa have supported hydrocarbon production to the tune of 1.8 million boe/d over an eight-year period…
The role of subsea sampling in securing maximum effectiveness from multiphase meters is reviewed here by Mirmorax chief executive Eivind Gransaether. He discusses how subsea sampling is addressing other crucial production management issues offshore…
The offshore oil & gas industry has long relied on sensors and sporadic ROV footage to find out what's going on subsea. Now a new tool designed for permanent deployment at well sites is about to change all that, according to Weatherford's Ole Tom Furu…
As gas wells mature and the produced gas becomes less able to carry water from the well, a decline in flow rate and production to rates below the anticipated decline curve often results. Bert Lugtmeier and Kees Veeken from Dutch operator NAM…
The steady workload situation at Schiedam-based HSM Offshore continues to be the envy of many North Sea fabricators. Business was good when OE last visited the yard a year ago; it’s got even better since, as David Morgan reports.Back in the summer of 2010 Total’s K5-CU platform (850t topsides…
When it comes to smart, or wise, ways to carry out subsea interventions, Wright's Well Control Services founder David Wright is a man of many ideas. Jennifer Pallanich catches up with him to discuss his company's latest kit and some of its recently completed projects…
An important milestone in Apache's UK North Sea Bacchus field development was reached recently with installation of a 6.7km pipeline bundle. The job was overseen by Flexlife, whose operations director John Marsden here describes how it was planned and executed…
Shell's solution for dealing with the heavy oil at the low-energy BC-10 concession offshore Brazil – caisson separator electrical submersible pumps - is working ‘outstandingly' well according to the field's project manager. Jennifer Pallanich…
While inspections are important in understanding the current status of subsea systems, limited information can be received about the internal health of critical subsea systems such as electrical power, hydraulic control and chemical injection…
Remediating plugged subsea lines in deep and ultra-deepwater is dangerous and time-consuming and can become extremely costly if coiled tubing or wireline intervention is required to resolve the problem. Champion Technologies’ Jeremy Lee describes…
Integrators charged with building chemical injection skids for medium-pressure applications face some formidable obstacles. Two of the chief obstacles concern critical fluid system components: medium-pressure instrument ball valves and reliable end connections for use with SAF 2507 tubing…
