  • The Snyder field is located in SE. Howard County, Texas, and covers approx. 6,000 productive acres. Production is obtained from approx. 400 wells. The portion of the Snyder field reviewed includes 12 leases with 65 producing wells and 30 newly drilled water-injection wells on these properties. The following subjects are discussed: geology of the field, the primary development of the field, primary production, waterflood history, pilot waterflood development, cooperative planning, drilling and completion of injection wells, water supply, water injection facilities, production equipment, and waterflood performance. After 6 yr of waterflood performance, some of the conclusions which can be mademore » include the following: (1) the Glorieta-San Angelo reservoir, as described, can be successfully waterflooded utilizing newly drilled and completed water-injection wells; and (2) high water- injection rates can be used and injection water quality does not seem to affect injection rates and pressures. Analyses of active waterfloods indicate the optimum injection well density is one new injector per 80 acres.« less
  • The SACROC Unit, encompassing about 98% of the reservoir, was formed in 1953 and initiated in Sept. 1954 a massive pressure maintenance program consisting of water injection into a centerline row of wells located along the longitudinal axis of the reservoir. This program, together with controlled production under unitized operations, has effectively rebuilt BHP, restored a large portion of the reservoir to liquid-saturated conditions, and stabilized producing GOR's at near solution levels. In 1968, a technical committee, investigating potential alternatives, recommended use of a water-driven slug of carbon dioxide to miscibly displace the oil in the nonwater- invaded portion ofmore » the reservoir and development of a pattern injection program in this area to implement the slug process and improve ultimate oil recovery. A summary is presented of the methods used in evaluating alternatives and designing the final program of COD2U injection, which was initiated in early 1972.« less
  • This study reviews the performance of the CO/sub 2/-Wag project conducted at the SACROC Unit since early 1972. Updated performance predictions indicate that incremental oil recovery over waterflooding will be in the range of 5.7 to 6.7% OOIP in the area processed with CO/sub 2/. Due to diminishing economic returns at higher CO/sub 2/ slug sizes the CO/sub 2/ slug limit was reduced to 12% HCPV in early 1977. Also discussed are the effects of measures (injection well profile control and WAG ratio variation) taken to improve volumetric efficiency, produced CO/sub 2/ and water cut performance and the volume ofmore » injected CO/sub 2/ required per STB of incremental oil.

  • A review is given of the mathematical derivation of the Courant and Snyder invariant which is well-known as the betatron emittance in accelerators or storage rings. It is shown that the existance of such an invariant is a remarkable characteristic of a linear system even for non-periodic motion.
  • The transverse motion of charged particles in a circular accelerator can be well represented by a one-turn high-order Taylor map. For particles without energy deviation, the one-turn Taylor map is a 4-dimensional polynomials of four variables. The four variables are the transverse canonical coordinates and their conjugate momenta. To include the energy deviation (off-momentum) effects, the map has to be parameterized with a smallness factor representing the off-momentum and so the Taylor map becomes a 4-dimensional polynomials of five variables. It is for this type of parameterized Taylor map that a method is presented for converting it into a parameterizedmore » Dragt-Finn factorization map. Parameterized nonlinear normal form and parameterized kick factorization can thus be obtained with suitable modification of the existing technique. 13 refs.« less
