Exploration & Production (E&P)
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. Top U. Detailed oil and gas field maps. The detailed field maps linked below portray the locations, boundaries, names, and either the barrel-of-oil equivalent BOE or the liquid hydrocarbon crude oil plus lease condensate or the natural gas reserve size classes of the known oil and gas fields in selected geologically defined areas of the U.
Oil and Gas Industry: A Research Guide
Well development occurs after exploration has located an economically recoverable field, and involves the construction of one or more wells from the beginning called spudding to either abandonment if no hydrocarbons are found, or to well completion if hydrocarbons are found in sufficient quantities. Production is the process of extracting the hydrocarbons and separating the mixture of liquid hydrocarbons, gas, water, and solids, removing the constituents that are non-saleable, and selling the liquid hydrocarbons and gas. Production sites often handle crude oil from more than one well. Oil is nearly always processed at a refinery; natural gas may be processed to remove impurities either in the field or at a natural gas processing plant. Finally, site abandonment involves plugging the well s and restoring the site when a recently-drilled well lacks the potential to produce economic quantities of oil or gas, or when a production well is no longer economically viable. Traditionally oil and gas wells are vertically drilled. Technological advancements have allowed operators to save time, reduce operational costs, and lessen their environmental impact.

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. Oil and gas exploration encompasses the processes and methods involved in locating potential sites for oil and gas drilling and extraction. Early oil and gas explorers relied upon surface signs like natural oil seeps, but developments in science and technology have made oil and gas exploration more efficient.
During the prospecting phase, petroleum E&P includes the use of subsurface geologic evaluation, seismic data and large computing power to process the.
An analysis of the exploration model that the oil and gas industry currently follows suggests that it often restricts innovation and inhibits exploration efforts. Examples of large, underexplored areas with significant oil and gas potential demonstrate how the current exploration model fails to allow adequate exploration efforts to be conducted. A description of a possible new exploration model is presented, involving the use of exploration technologies already available, as a means of breaking the paradigm of the current exploration model. Results of recent applications of such a model suggest that it can be applied both onshore and offshore, and that it is effective in detecting anomalies associated with significant hydrocarbon accumulations.

Phases of petroleum exploration and production
The petroleum industry , also known as the oil industry or the oil patch , includes the global processes of exploration , extraction , refining , transporting often by oil tankers and pipelines , and marketing of petroleum products. The largest volume products of the industry are fuel oil and gasoline petrol. Petroleum is also the raw material for many chemical products , including pharmaceuticals , solvents , fertilizers , pesticides , synthetic fragrances, and plastics. The extreme monetary value of oil and its products has led to it being known as "black gold".
Robert M. AAPG Bulletin ;; 81 7 : — In , Chevron Overseas Petroleum, Inc. Over the next five years, the process evolved into an effective method to plan exploration programs on a basis of value incorporating prospect ranking, budget allocation, and technology management. The final product is a continuous process and includes, within a single organizational unit, the integration of geologic risk assessment, probabilistic distribution of prospect hydrocarbon volumes, engineering development planning, and prospect economics.

И оба идете со. - В качестве заложников? - холодно усмехнулся Стратмор. - Грег, тебе придется придумать что-нибудь получше. Между шифровалкой и стоянкой для машин не менее дюжины вооруженных охранников. - Я не такой дурак, как вы думаете, - бросил Хейл. - Я воспользуюсь вашим лифтом. Сьюзан пойдет со .
Я поменялся сменой с новым сотрудником. Согласился подежурить в этот уик-энд. Глаза Стратмора сузились. - Странно. Я вчера говорил с .
