TECHNOLOGIC DEVELOPMENTS

 Cycling plants —Cycling operations in Texas increased at a slower
rate in 1941 than in 1940.. The daily average volume of gas processed in
December 1941 was 1,413 million cubic feet—a 14-percent gain over December
1940. The yield of liquid products represented a daily rate of 37,458' barrels
in December 1941 and 22,357 barrels in December 1940. The gain in cycling
operations was somewhat greater than the foregoing data indicate because
some repressuringplant statistics were included in December 1940 totals and
omitted in 1941.
 During 1941 the number of cycling and repressuring plants reporting to the
Railroad Commission of Texas increased from 32 to 45. In Louisiana the largest
cycling plant in the world began operating in July 1941 in the Cotton Valley
field, Webster Parish, and construction of a second large plant was started
in December 1941 at South Jennings, Jefferson Davis Parish. Construction
has begun on a cycling plant in the Katy field, Waller County, Tex., which
may surpass the Cotton Valley plant in volume of output.
 Yields.—Minor reductions in yield of natural gasoline were reported
in 1940 in all the prominent producing States except Illinois, where a slightly
higher yield was obtained. The chief gains in production were in such States
as Texas and Louisiana, where yields are below the national average owing
partly to the low yields from cycling operations. The influence of these
developments is expressed in a decline in average natural-gasoline yield
in the United States from 1.01 gallons per thousand cubic feet of gas processed
in 1939 to 0.95 gallon in 1940. Similar trends in production were evident
in 1941 and are thought to have caused a further slight decline in average
yields in that year.
