Circulation sub development brings prospect of totally clean completions closer to reality

Posted on 29 October 2009 in 2007, November/December

By Mike Churchill, Churchill Drilling Tools A significant step forward has been taken in achieving the total wellbore cleanliness that is a key factor in maximizing completion productivity. Obtaining that cleanliness is facilitated by the ability to circulate each section at will and with adequate flow to remove all contamination and debris. The evolution of […]

Intelligent completions technology has come a long way since ’97, but road ahead is long

Posted on 29 October 2009 in 2007, November/December

By Derek Mathieson, WellDynamics Earlier this year, WellDynamics celebrated the ten-year anniversary of the installation of the world’s first intelligent completion system. The result of a joint industry project, SmartWell technology in 1997 could have been just another start-up technology – innovative, untested and possibly infeasible from a commercial perspective. A decade later, however, the […]

By John H Hallman, Iain Cook, Weatherford International; Muhammad A Muqeem, Clark M Jarrett, Hamoud A. Shammari, Saudi Aramco Underbalanced drilling (UBD) has long been accepted as a viable well construction technique offering many benefits. UBD can avoid or minimize drilling issues such as lost circulation and stuck pipe. It increases rate of penetration (ROP) […]

Modified automated pressure-control technology offers smaller footprint for land MPD operations

Posted on 29 October 2009 in 2007, November/December

By Don Reitsma, Paul Fredericks, At Balance; Roger Suter, M-I SWACO The value of automated managed pressure drilling (MPD) technology in offshore operations can be measured by the impact it has had on economic drillability. It has demonstrated the ability to solve real world pressure problems that have blocked redevelopment of deepwater depleted fields and […]

Driller’s Method vs Wait and Weight Method: One offers distinct well control advantages

Posted on 29 October 2009 in 2007, November/December

By Rana S Roy, Conroy James Nini, Paul Sonnemann, Berton Thomas Gillis, Chevron The two widely used constant bottomhole circulating methods are the Driller’s Method and the Wait and Weight (W&W) Method. Well control experts are often strongly opinionated on selecting the better method to circulate an influx out of the wellbore. The purpose of […]

Japan Drilling ready for major expansion with new jackup, semi upgrade, Qatar joint venture

Posted on 29 October 2009 in 2007, November/December

For an indigenous Asian drilling contractor far away from the traditional activity centers of offshore drilling, being “international” has been more than a growth strategy for Japan Drilling Company (JDC). It has been a necessity. Ever since its very first drilling project in Indonesia in 1969, JDC has worked to establish an international presence, from […]
