Methods for accurately assessing the condition of a petroleum reservoir and designing and implementing a plan of action to increase production and recovery of petroleum from the reservoir. Information is gathered using a unique set of metrics and information gathering techniques and analyzed in a targeted fashion by properly weighting the data in the context of the particular reservoir and goals of the producer. A reservoir rating is generated using asymmetric analysis of metrics and then used to formulate a plan of action. Production architecture (e.g., number, location and manner of constructing oil and injector wells) is then constructed according to the plan of action. Reservoir performance can be continuously monitored and used to verify production and recovery goals and / or provide triggers or alarms to alter production equipment.

The invention discloses a tinosporae capillipes cutting propagation method. The tinosporae capillipes cutting propagation method comprises the steps that 1, cuttings are prepared, half-lignified tinosporae capillipes vines are selected, a section of each stem segment with one leaf is taken to serve as cuttings for standby application; 2, a rooting water solution is prepared, namely naphthylacetic acid, indolebutyric acid and 95% alcohol are respectively selected and mixed, water is added into the mixture till the volume of the mixture is 20 times of the volume of the alcohol, and the rooting water solution is obtained for standby application; 3, cutting processing and cottage are performed, namely the portions, close to the lower ends and with the length of 1.5-2.5 cm, of the cuttings prepared in the step 1 are soaked in the rooting water solution for 30-60 minutes, the portions are taken out and dried in a shade place, and the processed cuttings are put in a sand bed in a cottage mode for culture; The tinosporae capillipes cutting propagation method is applied to tinosporae capillipes cutting propagation and seedling raising, the cutting survival rate is above 90%, the seedling shortage problem can be effectively alleviated, and protection and restoration of endangered wild resources in the natural world can be achieved.

Provided is a rubber composition capable of providing a molding having: excellent sealing properties, heat resistance, and acid resistance; a low reaction force and low hardness; a reduced compression set; and especially an improved compression set and unsusceptibility to compression cracking at high temperatures. Also provided are a use of the rubber composition and a main body comprising the rubber composition mounted thereon. The rubber composition contains a specific ethylene / α-olefin / non-conjugated polyene copolymer [A], carbon black [B], and surface-modified silica [C] that is obtained by subjecting precipitated silica to surface modification and has a BET specific surface area of 30 to 80 m2 / g, a particle diameter of 1.0 to 4.0 μm as measured by the Coulter counter method, and an M value of 50 or more.
