Unconventional/complex reservoirs
Ranger acquires American Well Services for $90.5 million, adding 39 workover rigs and boosting its fleet by 25%.
The merger creates one of the largest oil-focused independents in the US with output of 526,000 BOE/D.
BPX Energy will retain operatorship of the assets after the sale of its interests to private investment firm Sixth Street is complete.
-
Tight gas reservoirs and shale gas reservoirs are economically viable hydrocarbon prospects that have proved to be successful in North America. -
Reserves- and resources-evaluation methods in unconventional reservoirs are different from those for conventional reservoirs.
-
Three observations have resulted from horizontal-well development in the Sulige tight gas field.
-
The North American shale-gas boom has highlighted the differences that a few years and a few thousand miles can make.
-
Natural-gas production from tight and shale-gas reservoirs will be increasingly important in China as the country shifts from coal-based energy to cleaner energy sources.
-
Gas in tight sand and shale exists in underground reservoirs with microdarcy or even nanodarcy permeability ranges; these reservoirs are characterized by small pore throats and crack-like interconnections between pores.
-
Europe and Australia have joined the US in expanding recoverable hydrocarbons from unconventional resources, and initial activities are on the rise elsewhere.
-
Tight reservoirs are still in the early stages of becoming a dominant source of energy and economic growth throughout the world for years to come. I recently read two distinctly different articles particularly relevant to tight reservoirs.
-
A multidisciplinary approach integrates fracture characteristics, reservoir production, and stress-field evolution to design and optimize the development of unconventional assets.
-
This paper sheds light on the nonlinear physics involved in the production of shale-gas reservoirs by improving the understanding of the complex relation between gas production, reservoir properties, and several treatment-design parameters.
