Process of making high VI lubes

Abstract: High VI lubes in high yields are obtained when lower or light olefins are polymerized over a ZSM-5 type catalyst the surface acidity of which has been inactivated by treatment with a suitable base material.

Method for hydrotreating and upgrading heavy crude oil during production

Abstract: Heavy crude oil containing at least 1% by weight water is hydrotreated and upgraded while being produced downhole in a production well. During production the heavy crude oil containing water is subjected to sonic energy at a low frequency of 400 Hz to 10 kHz downhole in the presence of a metal hydrogenation catalyst that causes the water in the crude oil to react and form hydrogen which then hydrotreats and upgrades the heavy crude oil during production. In another embodiment, if the heavy crude oil does not contain water, the hydrogen may be formed in-situ by contacting the heavy crude oil downhole with a chemical compound comprising ammonia, hydrazine and formic acid that in the presence of a metal hydrogenation catalyst and sonic energy causes the chemical compound to react and form hydrogen which then hydrotreats the heavy crude oil during production. Suitable catalysts include nickel on zinc dust, platinum on carbon and palladium on carbon, preferably nickel on zinc dust. The hydrotreated and upgraded heavy crude oil has improved properties making it easier to refine and transport by pipeline. The upgrading includes reducing the amount of asphaltenes and resins in the heavy crude oil and increasing the amount of aromatics and saturates.

Stress Magnitudes From Logs: Effects of Tectonic Strains and Temperature

Abstract: An improved method of calibrating in-situ stress logs has been validated with data from two wells. Horizontal stress profiles are useful for hydraulic fracture design, wellbore stability analysis, and sand production prediction. The industry-standard method of estimating stresses from logs is based on overburden Poisson's ratio, and pore pressure effects and outputs an estimate of minimum horizontal stress. The model proposed here adds effects of temperature and tectonics and outputs minimum and maximum horizontal stress magnitudes, which are particularly important to the successful completion of horizontal and deviated wells. This method was validated using data collected from a GRI research well and a Mobil well. Seven microfrac stress tests in GRI's Canyon Gas Sands well of Sutton County, TX, provided a means of comparing the predictive capability of different methods. First, one of the seven stress tests was selected as a calibration standard for the stress log. Then the results obtained from the two calibration methods were compared to stress magnitudes from the other six stress tests. This process was repeated using each of the seven stress tests as a calibration standard and comparing predictions to the other six. In every case, the method incorporating tectonic and temperature effects produced significantly more accurate values. In the Mobil well, pre-frac treatment breakdown tests were used to calibrate a log-derived stress profile. While reservoir pressure dominated stress variations, a significant deviation of the log value from the stress-test value in one layer was corrected when the method with tectonics and temperature was used.

Apparatus for loading bags

Abstract: An apparatus for dispensing individual plastic handle bearing bags from a stack of bags and holding the dispensed bag in an open position for loading. The apparatus comprises a bottom support member and two spaced-apart, oppositely disposed upwardly projecting tab members such that the apparatus has an opening corresponding approximately to the size of the open bag it is designed to contain. The upwardly projecting elongated tabs are compatible in size with the open portion of the bag handles and each is adapted to engage a handle of the bag in such manner that the bag is held suspended within the apparatus.
