Featured this monthThe Post-Macondo World: Two Years After the SpillAn examination of the oil spill’s effect on regulation, permitting, production, technology, safety, and the environment.
Opportunity, Challenge Meet on Arctic Horizon The Arctic represents a large expanse of opportunity for discovery and development of oil and gas resources, but one matched equally with technical challenges that test the limits of the industry.
R&D Grand Challenges The sixth in a series of articles on the great challenges facing the oil and gas industry as outlined by the SPE Research and Development Committee.
Assessing the Magnitude and Consequences of Reservoir Souring Reservoir souring, the unplanned increase in hydrogen sulfide in produced fluids during field life, is a growing concern for the petroleum production industry.
Talent & Technology Managers and the rank and file may disagree on whose career takes precedence in a dual career couple.
Management A look at the progress being made toward real-time drilling operations with drilling center support.
Drillers Find Themselves in a Tricky Spot at the Human/Machine Interface The pressure to do things better, faster, and more safely using computerized tools is creating complex management challenges.
Guest Editorial Steve Roberts, vice president of the Field of the Future for BP, ponders the next steps for the digital oil field.
Bob Carpenter, SPE, Research Consultant, Chevron Exploration and Technology CompanyThe number and economic contribution of unconventional (tight gas/shale and steamflood) wells continued to increase rapidly in 2011, as did the participation of major operators. That increased industry focus was evident again in the distribution of papers. Also, there were more papers relating advances in plug-and-abandonment, Arctic, high-pressure/high-temperature (HP/HT), and carbon-capture technologies.
More-Effective Plug-and-Abandonment Cementing Technique The effectiveness of a permanent abandonment plug is measured by its ability to bridge the wellbore cross section, both vertically and horizontally, including all annuli, with a plugging medium that can withstand the harsh environment to which it is exposed (Fig. 1). A new method is presented that creates a permanent abandonment plug by use […]
Cemented-Liner- vs. Openhole-Packer- Completed Tight Gas Horizontal Wells With the introduction of multiple-fractured horizontal-well (MFHW) technologies and with a much better definition of the geology, a large unconventional-resource play has developed in the Glauconitic formation in central Alberta, Canada, which could contain in excess of 5 Tcf of gas in place plus associated natural-gas liquid. Microseismic technology was used in a pilot project […]
Extreme-Environment Cementing in the Schoonebeek Heavy-Oil Field The Schoonebeek heavy-oil field was first developed by Nederlandse Aardolie Maatschappij B.V. in the late 1940s. Because of economics, it was abandoned in 1996. In 2008, the Schoonebeek Redevelopment Project, using a gravity-assisted-steamflood (GASF) design concept, was initiated with 73 wells (44 producers, 25 injectors, and four observation wells). A key design requirement was long-term […]
Real-Time Optimization of a Highly Complex, Integrated Gas System Real-time optimization (RTO) was used by Shell Malaysia E&P on the integrated gas-production system in Sarawak. Models for real-time monitoring and optimization of wells and facilities were implemented on a gas-production network spanning more than 100 wells on more than 40 platforms across several production-sharing contracts (PSCs). Digital technology enabled field-based data to be used […]
Multilateral / Extended Reach
Alvaro Felippe Negrão, SPE, Senior Advisor, Woodside Energy USAOur industry has been involved in incidents that demonstrated the need of a new approach for evaluating and mitigating the risks in well construction. The "what’s worked well in the past" conservative approach is not possible anymore, in face of the damaged trust of the public about upstream activity. Though the criticism soars against exploration and production activities, the industry has allocated substantial investments in research for new technologies aimed to preclude risk events of recent years. New procedures and technologies, in addition to existing ones, will be deployed in the near future to eliminate blowouts or underground contamination from upstream operations.
Pushing the Extended-Reach Envelope: Drilling a Record-Reach Well Extended-reach drilling (ERD) has become a common means to access reserves economically from existing infrastructure, provide access to reserves that were previously out of reach, and reduce the environmental footprint of drilling and production facilities. ExxonMobil, as operator for the Sakhalin 1 project, recently completed drilling operations at the Odoptu field, located offshore Sakhalin Island, Russia. The Odoptu development drilled […]
