OIL & GAS FIELD DEVELOPMENT <\/strong><\/p>\n

A hydrocarbon field has a long life cycle:<\/p>\n

From the discovery of a petroleum deposit to the first oil\/gas, exploration and production activities are spread over several decades. Five main steps can be distinguished in the life of an oil or gas field:<\/p>\n

EXPLORATION AND EVALUATION<\/strong>
\n 1 | Field discovery<\/strong>
\n> oil and gas are trapped in reservoir rocks buried underground (on shore\/ off shore),
\n> to locate hydrocarbon accumulation, Boost’s geoscientists analyze images of the earth\u2019s\u00a0subsurface produced by seismic echography. They build a model of geological layering\u00a0of the subsurface, and then identify potential reservoirs called \u00abprospects\u00bb,
\n> exploration wells need to be drilled to check if the identified prospect does indeed contain hydrocarbons. These wells are typically several kilometers deep.<\/p>\n

2 | Field evaluation<\/strong>
\nOnce discovery has been confirmed, 3D numerical reservoir simulation models are built:
\n> to estimate the initial volume of oil and gas in the reservoir,
\n> to simulate the reservoir fluid flow behavior and optimize the field development scenario (number, type and location of wells, level of field production, etc\u2026).
\nAppraisal wells are drilled to improve the field description through further data acquisition.<\/p>\n

An economic assessment is performed taking into account revenue according to production forecasts and the estimated development costs.
\nIf the required economic criteria are met, the field is developed and then produced.<\/p>\n

OIL & GAS PRODUCTION<\/strong>
\n 3 | Field development<\/strong>
\nA field development plan establishes the following:
\n> the number of wells to be drilled to reach production objectives,
\n> the recovery techniques to be used to extract the fluids within the reservoir,
\n> the type and cost of installations, such as platforms, depending on the marine\u00a0environment (tides, storms, waves, winds, corrosion, \u2026),
\n> the separation systems for gas and fluids,
\n> the treatment systems needed to preserve the environment.<\/p>\n

Rotary drilling is the most widespread drilling technique and has been constantly\u00a0upgraded: deviated wells, horizontal wells and, more recently, multi- drain wells. Those\u00a0new technologies allow to mitigate the surface foot print of the project and to increase\u00a0well productivity.<\/p>\n

4 | Field production<\/strong>
\nThe time period over which hydrocarbons may be extracted varies between 15 to 30 years\u00a0and may be extended up to 50 years or more for \u00abgiant fields\u00bb.
\nThe lifetime of a reservoir is composed of different successive phases:
\n> a period of production increase,
\n> a stabilization phase or \u00abplateau\u00bb,
\n> injection phases (water, gas or chemical products) to \u00abassist\u00bb the hydrocarbon\u00a0recovery and thus maintain a satisfactory volume of produced resources,
\n> the depletion period when hydrocarbon production declines progressively.<\/p>\n

Deep offshore
\nSignificant technological developments have been recently made in exploration and\u00a0production deep offshore (more than 1000 m water depth). Many wells have already been\u00a0drilled in this range of depth but producing deep offshore fields remains particularly\u00a0complex and expensive and still represents, today, a technological challenge.<\/p>\n

5 | Field abandonment<\/strong>
\nWhen the hydrocarbon production rate becomes non economical, the reservoir is abandoned.
\nBefore abandoning the field, Boost:
\n> dismantles facilities such as platforms,
\n> puts the well in a safe state,
\n> preserves the field\u2019s residual hydrocarbon reserves of the field,
\n> cleans, depollutes and rehabilitates the site.<\/p>\n","protected":false},"excerpt":{"rendered":"
