Managing Abandonment, Decommissioning, Remediation and Restoration throughout the E&P Lifecycle

Abstract

If retirement activities are deferred too late in the life of an exploration and production (E&P) asset, the number of retirement activities (i.e. well abandonment, facility decommissioning, site remediation, land restoration) could potentially exceed the funds, resources and time available. Large inventories of inactive assets (e.g. idle wells and facilities) carried long-term further compound the potential budgetary, resource, and schedule shortfall at end-of-life. A set of operating practices has been developed to systematically manage asset retirement throughout an E&P asset's lifecycle, enabling completion of retirement activities at a rational pace in alignment with the business unit's cash flow profile, resource availability, and lifespan. These practices guide inventorying, prioritizing and managing abandonment-decommissioning candidates (e.g. wells, pipelines, and facilities designated for retirement or inactive long-term), remediation candidates (sites with potentially impacted environmental media; inactive pits) and restoration candidates (borrow pits or disturbed land designated for restoration or inactive long-term) as an integral component of the asset's business plan. Technical guidelines for suspension, abandonment, decommissioning, site assessment, remediation and restoration complement the operating practices by driving task execution to world-class technical standards. Use of the operating practices described in this paper will position E&P business units to manage asset retirement progressively and perform the activities to world-class technical standards.

O nascimento da literatura policial e o espectador moderno: Algumas considerações a partir da 'arqueologia da modernidade' de Walter Benjamin

“…48 No entanto, mais que a visão panorâmica, o primo personifica uma disposição especial para a observação acurada, a de um "olho que realmente enxergue" e ao qual a cidade se mostra como "um cenário variado da vida burguesa". 49 A situação de isolamento e segregação do primo escritor, acometido por uma paralisia mas não abandonado pela fantasia, alude, pode-se dizer, ao "exílio do artista na moderna sociedade burguesa (como faria mais tarde o próprio Baudelaire na alegoria do poeta-albatroz)". 50 Mas, sob a figura do escritor como um olho apurado, o que sobressai é também a posição do espectador distanciado.…”
