Abstract Number

The term abstract refers to an original land survey describing an area transferred from the public domain by either the Republic of Texas or the State of Texas. These surveys are recorded in the "State Abstract of Land Titles," which is maintained by the Texas General Land Office. Each survey so recorded is assigned an abstract number, which is unique within the county in which the survey falls. Because Texas has never performed a uniform statewide land survey, these original surveys, called "Patent Surveys", constitute the State's Official Land Survey System.

API

The abbreviation for the American Petroleum Institute.

API Number

A unique, permanent, numeric identifier assigned for identification purposes to a wellbore. It consists of 10 digit. The first 2 digits are the state code (not shown on the map in the GIS viewer or in the GIS Wellbore attributes). The Texas State Code is 42. The next 3 digits are the county code (not shown on the map in the GIS viewer). The last 5 digits are the unique number assigned to identify the wellbore.

B

Bay Well

Any well under the jurisdiction of the Commission for which the surface location is either:
(a) located in or on a lake, river, stream, canal, estuary, bayou, or other inland navigable waters of the state; or
(b) located on state lands seaward of the mean high tide line of the Gulf of Mexico in water of a depth at mean tide of not more than 100 feet that is sheltered from the direct action of the open seas of the Gulf of Mexico.

The injected freshwater dissolves the salt and is pumped back to the surface as a saturated sodium chloride brine solution used as a feedstock in petrochemical refineries and in oil and gas well drilling and workover operations.

Section

A section refers to a square land survey measuring exactly one mile on each side. Some of the land transferred from the public domain by the state of Texas was surveyed and patented in units of square miles. The Texas General Land Office officially considers these units sections. Also, it was common that larger land grants, such as school lands and capitol lands, were subsequently surveyed into square mile units for the convenience of sale; these surveys are also called sections. In addition, the term "section" is commonly used to describe surveys in a group that have been assigned consecutive survey numbers, even though some of them do not have proper shape or size to truly be sections.
