By Jay Klassen and David Conroy, Smith Neyrfor As the demand for hydrocarbons in the United States continues to increase, reservoirs at depths of 15,000 ft or less are becoming increasingly depleted. Historically, 93% of all US production comes from formations above 15,000 ft, and current drilling trends document a negligible effort to discover or […]
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 […]
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) […]
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 […]
By Daniel F Eby, Cudd Well Control The drilling sector of the oil industry has made, and continues to make, great strides in advancing and applying new technology. Downhole tools for formation evaluation, extended-reach and horizontal drilling and temperature-tolerant fluids are used on a daily basis when 15 years ago they were only a recognized […]
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 […]
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 […]
By Linda Hsieh, associate editor To meet soaring energy demands at home, China is working harder than ever to reach out to the global drilling community for new technologies, new equipment, new reserves. Here’s a glimpse into CNPC’s projects, ambitions, challenges and more. In the center of Daqing, a city of more than two million […]
By Michael R Smith, Energyfiles This is the second of two articles discussing spending in the offshore drilling sector. The first, examining drilling spend by discipline, appeared in the July/August 2007 issue of Drilling Contractor. This part looks at spending by geographic area. Offshore drilling represents a substantial part of CAPEX in all operating regions. […]
