GLOSSARY 08 GLOSSARY NOMENCLATURE Production fields. Fields with exploration wells. These include operating wells, which are divided into injection and production wells, and closed wells with potential to be exploited in the future. Refining capacity. The daily operating capacity of a plant to produce refined products. Daily operating capacity means the maximum volume to be processed when the plant works without interruption. Condensates. Any mixture of relatively light hydrocarbons that remain liquid at normal temperature and have a certain quantity of propane and butane. Unlike crude oil, these contain little or no heavy hydrocarbons that constitute heavy crude oil. There are three main sources of condensates: a) liquid hydrocarbons that separate when natural gas is treated, typically consists of C5 to C8, b) liquid hydrocarbons coming from non-associated gas that are recovered at the surface, and c) liquid hydrocarbons coming from gas/condensate basins, which can barely be distinguished from a stabilized light crude oil. Drilling rigs in operation. The daily average number of drilling rigs used for drilling wells or in related activities such as dismantlement, transport and maintenance. Floating Production Storage and Offloading (FPSO). Floating Production Storage and Offloading vessel (also called a unit and a system ). A floating tank system used by the offshore crude oil and gas industry designed to receive, process, and storage crude oil or natural gas produced from nearby platforms, until the product can be offloaded onto waiting tankers. Instead, the FSO are not equipped with process systems. Natural gas. Light paraffinic hydrocarbon mixture, mainly methane, small quantities of ethane and propane and in variable proportions nitrogen, carbon dioxide and hydrogen sulfide. Natural gas can be associated with crude oil or be found alone in non-associated natural gas wells. 67

Dry gas. Natural gas free of heavier liquid hydrocarbons (natural gas liquids) consisting of ethane, propane, butane and natural gasoline. Sour gas. Natural gas containing hydrocarbons, hydrogen sulfide and carbon dioxide (the later in concentrations greater than 50 ppm). Wet gas. Natural gas containing more than 3 gallons of liquid hydrocarbons per thousand cubic feet of gas. Natural gasoline. A highly volatile hydrocarbon mixture of pentane and heavier. Usually added to automotive gasoline to increase vapor pressure and start gasoline engines at low temperatures. Also used by the petrochemical industry to produce isobutane and isopentane, used in alkylation processes. Liquefied petroleum gas (LPG). A gaseous mixture of propane and butane obtained during the fractionation of natural liquids or during the fractionation of refined products. It is the lighter fraction of crude oil utilized for domestic use and carburation. Special tax on production and services (STPS). An indirect tax on domestic sales of gasoline and diesel that Pemex-Refining collects on behalf of the Mexican Government. The difference between the retail price, or final price, and the producer price is the IEPS rate. The final price of gasoline and diesel is established by the Ministry of Finance (SHCP). The producer price of PEMEX is referenced to that of an efficient refinery in the Gulf of Mexico. San José Agreement. Crude oil cooperation agreement between Mexico and Venezuela that benefits Central America and Caribbean area and contemplates a collaboration scheme dedicated to finance economic development projects. Crude oil. Oil that comes from a reservoir after separating any associated gas. It does not include condensates and natural gas liquids production. Recovered crude oil is considered heavy or light according to the following approaches: Heavy. crude oil with API gravity less or equal to 27. Light. crude oil with API gravity between 27 to 38. Extra-light. crude oil with API gravity greater than 38. Three varieties of crude oil are exported: Maya. heavy crude oil with API gravity of 22 and 3.3% sulfur by weight. Istmo. light crude oil with API gravity of 33.6 and 1.3% sulfur by weight. Olmeca. extra-light crude oil with API gravity of 39.3 and 0.8% sulfur by weight. Wells Wells are classified according to their purpose or function, into development (including injection wells) and exploration (including wells by stratographic probe); and according to their completion grade, into drilled or completed. Drilled wells. Are those with completed operations with the rotary drill and cemented casing, but have not entered into subsequent operations that allow production. Completed wells.. Are those with completed operations regarding: installation of production pipelines; shots to the pipeline lining to allow communication between the interior of the well and the storing rock; and cleaning and stimulation of the rock to enhance the flow of hydrocarbons. Successful exploration wells. The relationship of currently producing exploration wells that incorporate reserves, divided by total completed wells. Since 2007, Pemex- Exploration and Production adopted the definition of Exploratory Commercial Success derived from international practices which evaluates the performance of exploration activities from an economic point of view. Pemex-Refining Processes. Alkylation. Process by which an isoparafine (of short chain) combines chemically with an olefin through a catalyst to form another isoparafine (of long chain), called alkylate. It s a major aspect of the upgrading of petroleum since it s formed of highoctane compound. Cracking. Process to break large molecules of crude oil into smaller ones: known as thermal cracking when the process is reached by the application of heat; catalytic cracking when a catalyst is used; and hydrocracking, when the process is carried out in a hydrogen atmosphere.. 68

Distillation. Process consisting on heating a liquid mixture until the most volatile components pass to the vapor phase, then the vapor is cooled down to recover these components by condensation. The main objectives of distillation are to separate a mixture of several components taking advantage of their different boiling points, or to separate the volatile materials of the non-volatile ones. Fractionation. Distillation process that separates small fractions of a hydrocarbon mixture. Hydrodesulfurization. Process that eliminates sulfur by transforming it to hydrogen sulfide in the gaseous stream, which can be easily separated and converted to elemental sulfur. Isomerization. Process that alters the fundamental arrangement of the atoms of a molecule without adding or subtracting anything to the original molecule. Butane is rearranged as isobutane to be used in the alkylation of isobutene and other olefins for high octane hydrocarbon production. Reforming. Process that improves the ontiknock quality of gasoline fractions by modifying their molecular structure: known as thermal reforming when is carried out by heat; and as catalytic reforming when catalyst is used. Petrochemical products These chemicals are produced from raw materials derived from crude oil and natural gas. According to the governmental resolution published on November 13, 1996, in the Official Gazette of the Federation, the categories of basic petrochemical products are constituted by those derivates that serve as basic industrial raw materials. These products can only be elaborated by the state through Petróleos Mexicanos and its subsidiary entities: 1.- Ethane 2.- Propane 3.- Butane 4.- Pentane 5.- Hexane 6.- Heptane 7.- Carbon black 8.- Naphtha 9.- Methane, when it comes from hydrogen carbides, obtained from reservoirs located in Mexican territory and used as raw material in industrial petrochemical process. In addition, Petróleos Mexicanos has petrochemical by-products and other products which, according to the generally adopted convention, are not petrochemicals but are elaborated in its petrochemical areas. Region A goegraphical area corresponding to the administrative division of Pemex- Exploration and Production. The regional heads are located along the Gulf of Mexico Coast: Poza Rica, Veracruz (Northern Region), Villahermosa, Tabasco (Southern Region) and Ciudad del Carmen, Campeche (Northeastern Marine Region and Southwestern Marine Region). Asset. An administrative subdivision of each region. Are maintained the integral asset: ATG, Burgos and Veracruz of the Northern Region, and the other integral assets change their name to productive assets, merging assets Macuspana and Muspac of the Southern Region: Northeastern Marine Region: Cantarell and Ku-Maloob-Zaap.(productive assets) Southwestern Marine Region: Abkatún-Pol-Chuc and Litoral de Tabasco (productive assets). Southern Region: Bellota-Jujo, Cinco Presidentes, Macuspana-Muspac and Samaria- Luna (productive assets). Northern Region: Burgos, Veracruz and ATG (integral assets) and Poza Rica-Altamira (productive assets). Reserves Estimated amount of hydrocarbons that can be commercially recovered from wellknown formations at a specific date. It is worth mentioning all estimated reserves involve some grade of uncertainty. The SEC permits oil and gas companies, in their filings with the SEC, to disclose only proved reserves that a company has demonstrated by actual production or conclusive formation tests to be economically and legally producible under existing economic and operating conditions. We use certain terms in this document, such as total reserves, probable reserves and possible reserves, that the SEC s guidelines strictly prohibit us from including in filings with the SEC. Proved reserves (1P). Estimated volumes of hydrocarbons which geological and engineering analysis demonstrates with reasonable certainty will be commercially recoverable in future years from known reservoirs under the prevailing economic conditions and existing operations; for example, prices and costs at the date of estimate. Prices include existing changes or contractual arrangements but are not based on future conditions. 69

STATISTICAL YEARBOOK Pemex 2013 ProbAble reserves (2P) Those reserves which analysis of geological and engineering data suggests are more likely to be recovered than to not being recoverable. If probabilistic methods are employed for evaluation, there is a probability of at least 50% that the amounts to be recovered will be equal to or greater than the sum of proved plus probable reserves, also called 2P reserves. PublIc PrIces The public prices that are presented correspond to different reference places, which are shown in the following table: Product Reference place PossIble reserves (3P) Those hydrocarbon reserves which analysis of geological and engineering data suggests are less likely to be recoverable than probable reserves. According to this definition, when probabilistic methods are employed, there is a probability of at least 10% that the amounts actually recovered will be equal to or greater than the sum of proved, probable and possible reserves, also called 3P reserves. domestic sales.
