The objective of the study is to provide the Alaska OCS Region with research and cost estimating regarding decommissioning of a typical arctic gravel island-based, oil and gas exploration/production facility. The work considered standard industry practice, available technology, current regulations (e.g. 30 CFR 250 Subpart Q) and market conditions.
To identify and assess alternatives to permits and other submissions for BSEE's essential functional areas that conduct oversight activities through permitting. These functional areas include: district field operations, regional firled operations, production and development, technical data management, and safety and environmental management. CFR Title 30, Part 250 Subparts: A,D,E,F,I,J,K,L, and Q for this effort.
This study provided a review of the state of the art decommissioning practices for oil and gas facilities in the U.S. Outer Continental Shelf (OCS).
The BSEE is seeking expert assistance to better inform BSEE decision-makers about current and future technical, regulatory and programmatic assistance programs and safety and environmental concerns worthy of BSEE engagement and interaction. The objective is to find technical, regulatory, and policy parallels in other countries to better inform BSEE management about how to improve BSEE'S own regulatory policies and structures to better regulate the industry.
The contractor performed a technical review and cost assessment applicable to Pacific OCS Region Offshore Facility Decommissioning. The specific tasks include: (1) review and update the decommissioning scenarios for OCS platforms, (2) review and update the engineering cost assumptions and methodologies, and (3) review and update the costs for each phase of the decommissioning process.
The basis for this project is to establish a best practice for evaluating cement plug seals for well abandonment, built on a comprehensive engineering study of the fundamentals governing cement plug seal performance. It will consist of laboratory and field investigations to assess the necessary attributes of the seal formed by a cement plug, and to determine the effects of wellbore geometry, cement properties, and placement methods on these attributes.
This project will identify the best and safest available methods of well abandonment that could be applied to extended reach, and ultra extended reach drilling wells. It will determine any limitation or challenges associated with the technologies and supporting surface equipment. Additionally, it will then propose possible solutions to these limitations and challenges, as well as potential new methods to set effective plugs in near horizontal wells.
Study the applicability of using epoxies and other gel, resin or grout materials as plugging agents in severely damaged wells where access is limited (e.g., Hurricane downed platform) and may be made only through subsurface intervention via intersection wells.
The purpose of this project was to establish a methodological framework for estimating the installation cost of offshore wind energy devices in the US OCS and providing removal cost estimates.
The scope of work was broken up into the following tasks:
Task 1. Review and synthesize the installation methods and costs of current and proposed offshore wind energy projects, internationally and domestically, using both primary and secondary data sources including interviews with project personnel;
