A Blue/Green Energy Revolution

Page:8

A seismic shift in the dialogue around big oil and climate has occurred in the past 12 months. It’s a change in how big oil is orientating itself around what many call the energy transition. Climate goals - governmental, international and industry…

Marginal Fields, Global Opportunity

Page:18

Unlocking marginal fields in the UK North Sea has led to a project comparing a global database of fields, discoveries and prospects, to clarify strategy for license holders and the supply chain alike in petroleum basins.In 2015, a project was…

From Marginal to Major

Page:22

It’s not your typical marginal field — centered on a concrete gravity-based structure (GBS) that once boasted production records — but Draugen in the Norwegian Sea had become “immaterial” to Shell. When it first delivered oil in 1993, Norwegians looked forward to the spoils in 1…

Raising the Pipeline Inspection Game

Page:26

There’s a shake-up happening in the pipeline inspections business. More evolved remotely operated vehicles (ROV), digital aspirations and unmanned surface vessels (USV) are driving a new era of data acquisition and deliverables.It’s offering…

2020 Offshore Exploration Outlook

Page:34

Exploration and production (E&P) companies are expected to enter 2020 with measured optimism for offshore exploration prospects, after 2019 delivered a moderate increase in exploration drilling and not-so-moderate rise in licensing activity…

The Future is in the North

CannSeal unlocks development of an additional reservoir by restoring integrity to an unconventional cement packer designAnnular isolation technology specialist CannSeal aided the successful repair of an unconventional cement packer design, 4 ½” in 9 5/8” with limited cement…

Ensuring Riser Readiness

Page:54

As drilling costs keep coming down for land-based wells in unconventional plays, offshore drillers face increased pressure to lower their costs. A key focus area: maintenance budgets for marine drilling risers. Instead of the traditional five-year…

Understanding Market Needs Can Shape Control Valve Design

Page:56

When it comes to smooth, safe drilling, you’d be hard-pressed to argue that the blowout preventer (BOP) stack isn’t the key to the whole operation. A series of mechanisms to regulate pressure levels in a well and prevent blowouts, which could potentially endanger personnel and the environment…
