Embodiments of the present invention relate to heater patterns and related methods of producing hydrocarbon fluids from a subsurface hydrocarbon-containing formation (for example, an oil shale formation) where a heater cell may be divided into nested inner and outer zones. Production wells may be located within one or both zones. In the smaller inner zone, heaters may be arranged at a relatively high spatial density while in the larger surrounding outer zone, a heater spatial density may be significantly lower.

In some embodiments, a ratio between a half-maximum sustained production time and a half-maximum rise time of a hydrocarbon fluid production function is relatively large.

Minute particles in a gas generated in a particle generating unit are charged by a charging unit. A concentrating unit concentrates charged particles in an introduced gas, and a collecting unit absorbs and collects the concentrated charged particles on a sample plate by an electrostatic force. In the concentrating unit, the charged particles are concentrated by decreasing a flow rate of a gas (carrier gas) in which particles are dispersed while maintaining the number of introduced charged particles. When the flow rate of the gas decreases, and spatial density of the particles increases, it is possible to efficiently collect charged particles on the small sample plate in the collecting unit, and to shorten a collection time.
