This is a Joint Industry Project (JIP). Two tasks were set for the project:
1) Develop a comprehensive understanding of the nature and extent of the gas migration problem. A survey form was prepared, interviews with cementing experts are taking place, and a database of relevant information is being developed;
2) Conduct screening studies of existing remedial solutions.
This JIP was formed to develop a preliminary model of riser reliability. The insights gained by this model will be used to generate a road-map for the development of a more refined model of riser reliability. The preliminary model will also allow the structure and location- specific reliability results, which will be useful in the evaluation of the reliability inherent in current designs.The study originally planned to consider both a TLP production riser and a drilling riser, each in 1000 meters of water.
The project examined the leakage rates for surface safety valves (SSV), underwater safety valves (USV), and subsurface safety valves (SSSV) and the reliability of certified SPPE versus non-certified SPPE. The project also tested two subsurface-controlled SSSV to see how closely they operated to their designed performance. The project specifically examined the differences between the leakage rates specified by MMS regulations and API 14 and 6AV1.
Results:
The project is complete and their findings are available in the final report. The highlights of the project are:
This is a Joint Industry Project (JIP) with 35 members, to support the development of an Offshore Technology Research Center (OTRC). The OTRC will develop solutions to structural problems that are faced in drilling and production in deep water. Research focuses on the interactions between structures and fluid, materials and the seafloor. As a partner the MMS will receive access to all technology developed at the OTRC.
This is a Joint Industry Project (JIP). The purpose of this project is to develop a model to predict the rate of hydrate plug decomposition; to measure the mobility of hydrate plugs with/without kinetic inhibitors; and to characterize the morphology of gas hydrates.
This is a Joint Industry Project(JIP) with 36 members. The objective was to develop an integrated model to predict paraffin deposition in two-phase (gas/oil) production systems. Three aspects were studied: flow loop and deposition, thermodynamics and fluid characterization, and heat transfer.
Produce a written review of the state of the art in topics as the prevention of hydrate formation and removal of hydrates during drilling, production, transportation, and other processing of hydrocarbons. These topics will become increasingly important to the safety of operations as industry moves into the deeper parts of the Gulf of Mexico, where the colder temperatures cause more hydrate
This is a Joint Industry Project (JIP). The purpose of this project was to verify engineering designs for deep water SPAR drilling, production and storage systems. SPAR is a large, stable, deep draft, cylindrical floating caisson designed to support drilling and production operations. The SPAR can store produced oil if needed. Wave tank testing was done at as large a scale as possible to verify engineering design calculations for SPAR. Emphasis was placed on confirming the slowly varying second order responses which dominated the global surge and pitch motions of the SPAR.
To develop a generic cost effective subsea oil and gas production system design for deepwater operations in the Gulf of Mexico.
The goal of this project was to develop a reliability database that will increase the confidence in the methodology used to develop safety systems, thereby increase the safety of offshore developments. The basis of achieving the objectives of this work was to secure the support of operators associated with the Minerals Management Service to ease the gathering of data relating to the performance of safety and pollution control devices within the offshore environment.
