The Wyoming properties, mainly waterflood developments in the Big Horn and Wind River basins, averaged 16,500 barrels of oil equivalent per day in first quarter 2016 production.

The Glen Pool field still produces a relatively small flow of oil in the 21st Century using waterflood techniques. Over its life span, the field has produced more than 340 million barrels of oil.

CRC continued the development of the waterflood, but also tested the viability of the Monterey formation. The Monterey formation at Buena Vista has proven to be a viable target and is currently being developed.

Several enhanced recovery methods were used during the field's history. In 1954, operators began gas injection into the Wayside pool, discontinuing it in 1961. After the 1957 peak, operators began a waterflood operation in the Wayside pool, and in 1959 in the Rancho pool. In this method, water is pumped back into the reservoir to replace fluid previously removed, increasing reservoir pressure and driving remaining oil to recovery wells.DOGGR, 170-171 In the Southeast Area of the field, gas injection was used from 1960 to 1966, and waterflood from 1972 to 1975, the year the Wayside 13 reservoir was converted to gas storage.

By 1983, the deepest well was already producing from . In order to increase reservoir pressure, several waterflooding projects have been undertaken on the field, commencing in 1955. Most of the water injection has been done in the Grubb 1-3 zones; only one waterflood well was active as of 2009 in Grubb 4-5, with 31 in Grubb 1-3.

Both of these enhanced recovery technologies increased pressure in the field, allowing increased oil recovery, which approximately doubled as a result. In the late 1970s, production again dropped, and Marathon commenced another waterflood project, this time followed closely by a pattern polymer flood. The polymer flood was ended in 1989. The 1 billionth barrel of oil was produced on January 11, 1985.

As of year end 2006 the field had a total reserve of only about one percent of its original oil, and having produced a mere .California Department of Conservation, Oil and Gas Statistics, Annual Report, December 31, 2006, p. 2 Since, the field has gone through a revitalization. Crimson Resources initiated a waterflood in the Etchegoin formation, saw good response and sold the asset to Occidental Petroleum (now California Resources Corporation, CRC).

Heavy crude oil is a sister resource to bitumen. It is lighter than bitumen and its reservoirs are much smaller than the great oil sands deposits. Like the oil sands, only a small percentage of Canada's large heavy oil resource is producible. Often called conventional heavy oil, this low-density oil can be recovered by conventional drilling techniques or by waterflood, a technique of injecting water into the reservoir to increase pressure, thus forcing the oil toward the well bore.

This turned out to be another productive reservoir, with an average thickness of for the producing formation. In spite of the methodical early development of the field, the peak production did not occur until 1959, after the waterflood in the Sespe zone had been running for three years, and four years after the discovery of the productive Bridge zone north of the Oak Ridge Fault. In 1959 the field produced over of oil and in 1960 of natural gas. In the 1990s, the major oil companies pulled out of the field and sold their holdings to independent and smaller operators.

Tracers are used in the oil industry in order to qualitatively or quantitatively gauge how fluid flows through the reservoir, as well as being a useful tool for estimating residual oil saturation. Tracers can be used in either interwell tests or single well tests. In interwell tests, the tracer is injected at one well along with the carrier fluid (water in a waterflood or gas in a gasflood) and detected at a producing well after some period of time, which can be anything from days to years. In single well tests, tracer is injected into the formation from a well and then produced out the same well.

DOGGR, p. 420-421 Chanslor-Canfield Midway Oil Co. discovered the Oak Grove Area in 1931, and Continental Oil Co. found the Padre Canyon area 1936. The deeper zones from both of these areas were not found for another 30 years.DOGGR, p. 422-424 Waterflooding of the field began in 1961, and most zones had active waterflood operations by the end of the 1960s.DOGGR, p. 420-424 Peak production from the entire field was in 1972, when the various producers reported over 4.6 million barrels for the year.DOGGR, p. 419 This broke a usual pattern for California oil fields, in which the peak production was typically within the first few years after discovery, with a secondary peak occurring after the development of enhanced-recovery technologies in the 1960s. In 1993, Vintage Petroleum acquired both the Rincon and adjacent San Miguelito oil fields from Mobil, Conoco, and Santa Fe Energy. For operational efficiency, Vintage combined the two adjacent oil fields into a single operating unit.
