Paper: HNG Oil Companys Development and Production Techniques In Sutton County Sand Pays

The purpose of this paper is to discuss HNG Oil Company's drilling, completion, and producing operations in the Sawyer (Canyon) Field, Sutton County, Texas. The field is located south of Sonora, Texas as shown in Fig. 1. HNG has 134 productive wells, 60 percent of the field, on 58,000 acres with 220 offset proven locations yet to be drilled. The Canyon in this area is characterized by limited extent low permeability lenticular sands. The average well stabilizes at approximately 300 MCFPD and has an initial bottomhole pressure of about 1900 psi. Because of these characteristics and the initially low gas price (18c/MCF). The original economics were marginal. This necessitated a streamlining of operations to make the venture economical.
