Brea-Olinda Oil Field
The Brea-Olinda Oil Field is a large oil field in northern Orange County and Los Angeles County, California, along the southern edge of the Puente Hills, about four miles (6 km) northeast of Fullerton, and adjacent to the city of Brea. Discovered in 1880, the field is the sixteenth largest in California by cumulative production, and was the first of California's largest 50 oil fields to be found. p. 63 It has produced over 430 million barrels of oil in the 130 years since it was first drilled, and retains approximately 20 million barrels in reserve recoverable with current technology. As of the beginning of 2009, 475 wells remained active on the field, operated by several independent oil companies, including Linn Energy, BreitBurn Energy Partners L.P., Cooper & Brain, and Thompson Energy.DOGGR 2009, p. 115, 121, 136, 158 Setting The Brea-Olinda field occupies a long, narrow band along and south of the Whittier Fault Zone, which forms the southern boundary of the Puent ...

California State Route 57
State Route 57 (SR 57), also known as the Orange Freeway for most of its length, is a north–south state highway in the Greater Los Angeles Area of the U.S. state of California. It connects the interchange of Interstate 5 (I-5) and SR 22 near downtown Orange, locally known as the Orange Crush, to the Glendora Curve interchange with I-210 and SR 210 in Glendora. The highway provides a route across several spurs of the Peninsular Ranges, linking the Los Angeles Basin with the Pomona Valley and San Gabriel Valley. A predecessor to this road ran through Brea Canyon by the early 20th century and was added to the state highway system. The freeway was built in stages during the 1950s, one of which included the Brea Canyon Freeway; SR 57 was designated as part of the 1964 state highway renumbering. The final portion of the present-day Orange Freeway was not completed until the mid-1970s. The latest piece of SR 57 to be added was formerly part of I-210, after SR ...

Los Angeles City Oil Field
The Los Angeles City Oil Field is a large oil field north of Downtown Los Angeles. Long and narrow, it extends from immediately south of Dodger Stadium west to Vermont Avenue, encompassing an area of about four miles (6 km) long by a quarter-mile across. Its former productive area amounts to . Discovered in 1890, and made famous by Edward Doheny's successful well in 1892, the field was once the top producing oil field in California, accounting for more than half of the state's oil in 1895. In its peak year of 1901, approximately 200 separate oil companies were active on the field, which is now entirely built over by dense residential and commercial development. As of 2011 only one oil well remains active – behind a fence on South Mountain View Avenue one block east of Alvarado Street in the Westlake, Los Angeles, Westlake neighborhood, producing about . p. 94. The fortunes made during development of the field led directly to the discovery and exploitation of other fields ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
API Gravity
The American Petroleum Institute gravity, or API gravity, is a measure of how heavy or light a petroleum liquid is compared to water: if its API gravity is greater than 10, it is lighter and floats on water; if less than 10, it is heavier and sinks. API gravity is thus an inverse measure of a petroleum liquid's density relative to that of water (also known as specific gravity). It is used to compare densities of petroleum liquids. For example, if one petroleum liquid is less dense than another, it has a greater API gravity. Although API gravity is mathematically a dimensionless quantity (see the formula below), it is referred to as being in 'degrees'. API gravity is graduated in degrees on a hydrometer instrument. API gravity values of most petroleum liquids fall between 10 and 70 degrees. In 1916, the U.S. National Bureau of Standards accepted the Baumé scale, which had been developed in France in 1768, as the U.S. standard for measuring the specific gravity of liquids less den ...

Miocene
The Miocene ( ) is the first epoch (geology), geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene followed the Oligocene and preceded the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by distinct global events but by regionally defined transitions from the warmer Oligocene to the cooler Pliocene Epoch. During the Early Miocene, Afro-Arabia collided with Eurasia, severing the connection between the Mediterranean and Indian Oceans, and allowing the interchange of fauna between Eurasia and Africa, including the dispersal of proboscideans and Ape, hominoids into Eurasia. During the late Miocene, the conn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pliocene
The Pliocene ( ; also Pleiocene) is the epoch (geology), epoch in the geologic time scale that extends from 5.33 to 2.58See the 2014 version of the ICS geologic time scale million years ago (Ma). It is the second and most recent epoch of the Neogene Period in the Cenozoic, Cenozoic Era. The Pliocene follows the Miocene Epoch and is followed by the Pleistocene Epoch. Prior to the 2009 revision of the geologic time scale, which placed the four most recent major glaciations entirely within the Pleistocene, the Pliocene also included the Gelasian Stage, which lasted from 2.59 to 1.81 Ma, and is now included in the Pleistocene. As with other older geologic periods, the Stratum, geological strata that define the start and end are well-identified but the exact dates of the start a ...

Puente Formation
The Puente Formation is a Formation (geology), geologic formation in California. It preserves fossils dating back to the middle to upper Miocene epoch of the Neogene Period (geology), period, most of which were deposited in a deepwater environment. Owing to its depositional environment, it is one of the very few geologic formations to preserve articulated specimens of fossilized Ceratioidei, deep-sea anglerfish.As its name suggests, it primarily outcrops in the Puente Hills. Paleoecology The Yorba Member of the Puente Formation preserves some of the world's only known fossils of deep-sea anglerfish, most of which were discovered during the construction of a rail line. These anglerfish are assigned to several genera and species that inhabit Dead zone (ecology), hypoxic, upwelling-influenced subtropical and tropical environments in the eastern Pacific today, suggesting that the composition of these ecological communities has changed little in the time since the deposition of this f ...

Sedimentary Rock
Sedimentary rocks are types of rock (geology), rock formed by the cementation (geology), cementation of sediments—i.e. particles made of minerals (geological detritus) or organic matter (biological detritus)—that have been accumulated or deposited at Earth's surface. Sedimentation is any process that causes these particles to settle in place. Geological detritus originates from weathering and erosion of existing rocks, or from the solidification of molten lava blobs erupted by volcanoes. The geological detritus is transported to the place of deposition by water, wind, ice or Mass wasting, mass movement, which are called agents of denudation. Biological detritus is formed by bodies and parts (mainly shells) of dead aquatic organisms, as well as their fecal mass, suspended in water and slowly piling up on the floor of water bodies (marine snow). Sedimentation may also occur when dissolved minerals precipitate from aqueous solution, water solution. The sedimentary rock cover of ...
