Many foreign companies entered and explored Mexican oil fields, making it the second largest producer of crude oil by International companies, including Shell, Exxon, the Pearson family, Sinclair, and Gulf Oil, largely controlled oil production until PEMEX was established in and reported average oil production of 44 million barrels.

New investment led to an increase in its reserves, which reached a high of 57 billion barrels in Similarly, its combined production of crude oil and natural gas, which peaked in , decreased by about one-third to reach 3.

That growth continued until the mids. However, in , authorities wanted to adopt international standards. These agencies applied criteria and standards of the Society of Petroleum Engineers and the Society of Petroleum Evaluation Engineers, which were endorsed by the World Petroleum Congress and accepted by the United States and the international petroleum industry. Based on this new methodology, reserves were downgraded by more than 50 percent.

On the other hand, resource consumption had been constantly increasing due to industrial growth and demographic demand for energy. Sources: BP statistical review of world energy , excludes shale reserves. It is a major crude oil exporter with exports constituting Historically, revenues from oil exports have been one of the main sources of income for the Mexican government. However, oil export revenues have consistently declined in the past few years. Mexico has been one of the largest crude oil producers for many years.

However, the country has been a net importer of refined fuel products. This is due to the fact that Mexican refineries are not equipped to process the heavy oil produced in the region, unlike the refineries in the southern United States.

Hence, Mexico imports petroleum products from the United States to meet its domestic demand. In fact, during —, inward remittances from the United States surpassed crude oil revenues for the first time—and even doubled by December according to Forbes. State of refineries in Mexico. As of , their total refining capacity was 1. This is largely due to unplanned outages and the ongoing challenge to produce clean gasoline and distillate fuels from the available marginal barrel of heavy sour crude oil.

These resources are located near the states of Veracruz, Tabasco, and Campeche. The United States is the biggest consumer and importer of this crude oil from Mexico, as it has some of the most sophisticated refineries capable of processing such heavy crude.

The Cantarell basin was discovered in and its production began in The field was once considered the largest and most prolific oil field in the world. Production stagnated due to falling reservoir pressure and was later placed on nitrogen injection during Peak production was reported in at 2. However, output has drastically declined since then. The total contribution of Cantarell to Mexican crude oil production fell from 63 percent in to a mere 10 percent in figure 4. Following energy reforms, some of the acreage was included in bidding rounds for auction.

According to the EIA, Mexico has enormous potential for shale gas and oil resources. These are expected to be stored in marine-deposited, source-rock shales distributed along the onshore Gulf of Mexico region. Technically recoverable shale resources are estimated at trillion cubic feet Tcf of gas and The Burgos basin extends from south Texas to northern Mexico and has estimated potentially recoverable resources of Tcf of gas and 6.

This indicates the high potential of shale gas resources in Mexico. During bid rounds two through four, the Mexican government will auction a total of 14, sq. The legislation introduced new contract models for exploration and production, such as licenses, service contracts, profit sharing, and production-sharing agreements. Need for reforms. Two of the most important amendments made to the bill by the Senate were :. Eight months later, on August 11, , the president signed into law the 21 component parts of a comprehensive energy reform.

These issues can be categorized into two parts, namely 1 tax and financial obligations and 2 governance and political responsibilities.

The reform imposed responsibilities on government agencies to ensure commitment and transparency for implementing the new law. The allocation equals PEMEX would have access to The following resources were allotted to develop:. From to , Round One included auctions of onshore and offshore fields to global participants. The first tender saw 14 blocks of offshore shallow-water reserves in the southern gulf go up for auction, but only two blocks received successful bids.

The acquired blocks were off the coasts of the Veracruz and Tabasco states, holding around million BOE. The second tender was held in September and was comparatively better received by the industry players. Five shallow-water blocks were up for auction and three were granted to different companies or consortiums via production-sharing contracts. The bids were won by both international and national companies including Eni S. This tender unexpectedly received the highest premium.

In the third phase that commenced in December , all 25 licenses were awarded for smaller onshore fields. In total, 22 companies participated and 18 of them were Mexican entities. In the fourth auction held in December , tenders were offered for 10 deepwater reserves. The implementation of energy reforms in Mexico resulted in the allocation of major resources in the deep waters of the Gulf of Mexico and shale resources in the Burgos basin to PEMEX. Since then, PEMEX has transformed from a decentralized public entity into a productive state-owned company.

Mexican authorities completed transparent and competitive bidding rounds for all phases of Round One. From Round Two, the Mexican government will provide year production-sharing contracts with the possibility of a year extension. The first phase of Round Two was announced in July and was auctioned on June 19, Authorities awarded 10 out of 15 blocks in the Gulf of Mexico.

The bidding day started slowly with participating companies showing interest in only the Tampico-Misantla and Veracruz areas. However, the bids started rolling once areas in the southeast basin were offered. Twenty individual companies and 16 consortia from 15 countries participated in Round 2.

The Mexican subsidiary of Eni S. Many foreign companies including Chevron, Repsol, Shell, and Total participated in the auction. The government considered the auction successful and has been satisfied with its outcome. Mexico has attracted investments from all regions: 37 percent from Asia Pacific, 36 percent from Europe and Eurasia, 13 percent from the United States, 12 percent from Mexican players, and 2 percent from South and Central American companies.

Each of these subsidiaries is a legal entity and can conduct business under its name. The subsidiaries are technically and operationally self-sufficient. These reforms have provided PEMEX with various opportunities for strategic alliances and partnerships to develop and explore its vast allocated resources.

The Trion block was discovered by PEMEX in and is expected to have 3P reserves totaling million barrels of crude oil equivalent.

Once operational, the block is expected to produce more than , barrels of crude oil equivalent per day. The corresponding exploration and production contract, joint operating agreement, and other relevant agreements were signed on February 28, During the Round 2. Sophisticated techniques to convert resources into production.

Addressing infrastructure challenges. It seemed to receive a lukewarm response from foreign investors. Its primary responsibility is to oversee and manage crude oil and natural gas transportation infrastructure in Mexico. The expansions will be needed within the next 15 years to avoid pipeline bottlenecks, especially in southern Mexico, and to handle natural gas and oil products.

To explore Mexican resources, companies will likely need to use new drilling techniques, especially for deepwater reserves, and new technologies such as fracking and horizontal drilling. Investments The bidding rounds were able to attract considerable foreign investments in Mexico. Workforce skills New companies entering Mexico will require talent, and hiring the right skilled workforce could be a big challenge for both the country and industry. According to government estimates, , new jobs will be created by Randy B.

Hydrocarbon exploration

Walter K. AAPG Bulletin ;; 36 8 : — A look at the exploration history of the important oil areas of the world proves conclusively that oil and gas seeps gave the first clues to most oil-producing regions. Many great oil fields are the direct result of seepage drilling. Seepages are most numerous in the youngest sediments, especially where they have been folded, faulted, and eroded, and on the margins of basins. Exceptions are easily explained by a comparatively calm geological history as depicted by the Gulf Coast region, West Texas, the Mid-Continent, and areas bordering stable masses. Many seepages are the result of destruction of major accumulations of oil reservoirs.

Considered being the biggest sector in the world in terms of dollar value, the oil and gas sector is a global powerhouse using hundreds of thousands of workers worldwide and generating hundreds of billions of dollars globally each year. In regions which house the major NOCs, these oil and gas companies are so vital they often contribute a significant amount towards national GDP. The energy sector has three key areas: Upstream , midstream and downstream. The largest volumes of products of the oil and gas industry are fuel oil and gasoline petrol.

The following maps show the drilling history and oil and gas production of selected low-permeability, continuous-type shale reservoirs. Selected geologic characteristics pertinent to occurrence of producible oil and gas resources are also shown when available. The Volumetrically Largest U.

Oil and Gas Industry: A Research Guide

Exploration and production snapshots: Mexico

Given the current extreme severe weather across the State, the oil and gas industry has worked to maintain production to provide sources of energy for power generation. These SWD wells are essential to the continued operation of oil and gas wells as they provide for the disposal of waste associated with oil and gas production, including produced water. The shutdown of SWD wells results in an overall reduction of disposal capacity at a time when demand for that disposal capacity remains high. In the absence of adequate disposal capacity, operators may be forced to curtail production of oil and gas.

Light and sweet crude oil is usually priced higher, and therefore more sought-after, because it is easier to refine to make gasoline than heavy and sour crude oil. Natural gas is found in both associated formations, meaning it is formed and produced with oil, and non-associated reservoirs. Gas can either be dry pure methane , or wet exists with other hydrocarbons like butane. Although wet gas must be treated to remove the other hydrocarbons and other condensates before it can be transported, it can increase producers' revenues because they can sell those removed products.

Hydrocarbon exploration or oil and gas exploration is the search by petroleum geologists and geophysicists for deposits of hydrocarbons , particularly petroleum and natural gas , in the Earth using petroleum geology. Visible surface features such as oil seeps , natural gas seeps, pockmarks underwater craters caused by escaping gas provide basic evidence of hydrocarbon generation be it shallow or deep in the Earth. However, most exploration depends on highly sophisticated technology to detect and determine the extent of these deposits using exploration geophysics. Areas thought to contain hydrocarbons are initially subjected to a gravity survey , magnetic survey , passive seismic or regional seismic reflection surveys to detect large-scale features of the sub-surface geology. Features of interest known as leads are subjected to more detailed seismic surveys which work on the principle of the time it takes for reflected sound waves to travel through matter rock of varying densities and using the process of depth conversion to create a profile of the substructure. Finally, when a prospect has been identified and evaluated and passes the oil company's selection criteria, an exploration well is drilled in an attempt to conclusively determine the presence or absence of oil or gas.
