Collaboration adds MPD functionality to deepwater rig

An operator, drilling contractor and service company collaborated on the conversion of an “open-to-atmosphere” deepwater rig, to provide full managed pressure and closed loop drilling capabilities.  

Lightweight risers increase rigs’ water depth ratings

The deepwater, lightweight riser system, incorporating improvements derived from nearly a decade of operation, can extend the water depth range of rigs to 8,000 ft.

Features

Meeting offshore challenges with new rig designs

New offshore rig designs feature a drillship capable of drilling 40,000-ft wells in a 12,500-ft water depth, with 20,000-psi well control; a platform rig with hydraulic hoist; a jackup with P&A capabilities; and integrated software for quality management.

Acoustical determination of cement thickness in cased wells

The thickness and reliability of cement in a cased well is a matter of concern for both service companies and operators.

Building understanding of offshore Congo regional geology through 3D seismic

Exploration offshore Congo is moving into deeper water, with discoveries, such as Moho Bilondo, helping to de-risk the petroleum system.

What’s new in well logging and formation evaluation

Part 2: In this final installment of a two-part series, the author highlights developments in wireline cased-hole logging, reservoir monitoring, coring, wellsite evaluation and laboratory techniques.

Riding a high tide, Norway plans for the future

As operators push Norwegian E&P activity close to record highs, the government and industry are working together to plan future upstream growth prudently while keeping costs under control.

ONS: Changes lie ahead, and below, for the oil and gas industry

In the same way that operators, service companies and manufacturers have switched gears to respond to the changing oil and gas landscape offshore Norway, the UK and mainland Europe, the organizers of this year’s Offshore Northern Seas (ONS) event have also updated their focus.

Shale Technology Review

Best practices for more production, less HSE impact

It was only 1981, when George Mitchell began experimenting with horizontal drilling and hydraulic fracturing in the Barnett shale.

Factory drilling is no substitute for formation evaluation

In a push to reduce costs in unconventional shale play reservoirs, some in the industry are racing to systematize development processes, even before understanding many of the aspects that play a role in shale production.

Finding sweet spots and optimizing completions through G&G advances

Recent advances in a number of G&G techniques, such as full-azimuth imaging, deep shear wave imaging, integrated wireline evaluation and microseismic monitoring are improving results in unconventional plays

New technologies tackle drilling efficiency and HSE issues

New technologies enabling increased drilling efficiency, with reduced HSE footprint, include real-time, remote monitoring centers, walking rigs, fluids cycle automation and remote pipe racking. 

Fracturing technology continues to advance

The E&P industry is known for building on past successes, and hydraulic fracturing technology is no exception.

Water management tools and techniques continue to expand

To use water resources more efficiently during hydraulic fracturing associated with shale development, the E&P industry continues to add new devices and innovative techniques, including this collection of eight recent items.
