海上固体处理的主要作用是在不中断或关闭的情况下正确清除和处置产生的固体。大多数砂管理研究仅关注分离部分。然而,该工艺80%的资本支出(CAPEX)归因于分离装置,80%的运营支出(OPEX)涉及脱水、运输和处置(DTD)。完整的论文概述了设施设计过程中必须提出的问题,并提供了分离后要实施的砂处理过程的每个步骤的指南、计算和示例。

设施沙子管理 (FSM)

FSM是指碳氢化合物生产和加工系统中从井口到贸易交接的固体处理过程,基于工程知识和一定程度的技能。

FSM 不是废物流处理活动,而是一个关键的流量保证问题。即使存在固体,也能维持(或增加)生产和正常运行时间,同时最大限度地减少或降低运营成本。

Study Outlines Steps for Dewatering, Transport, and Disposal of Produced Solids

This paper outlines issues to be resolved during facility design and provides guidelines, calculations, and examples for sand-handling steps to be implemented after separation.

The primary role of offshore solids handling is to remove and dispose of produced solids properly, without interruption or shutdown. Most sand-management studies focus on the separation component only. However, 80% of the capital expenditure (CAPEX) of the process is attributed to separating devices, and 80% of the operating expenditure (OPEX) involves dewatering, transport, and disposal (DTD). The complete paper outlines questions that must be asked during facility design and provides guidelines, calculations, and examples on each of the steps of the sand-handling process to be implemented after separation.

Facilities Sand Management (FSM)

FSM refers to the solids-handling processes in the hydrocarbon production and processing system from the wellhead to custody transfer, based on engineering knowledge and a certain degree of skill.

FSM is not a waste-stream-treatment exercise but a critical flow-assurance issue. Production and uptime are maintained (or increased) even when solids are present, while the operating costs are minimized or reduced.
