HPHT Phase II - API 17TR8 (Evaluation of Pressure Rating Methods Recommended by API RP 17TR8)

The original objective was to evaluate testing alternatives during Phase I of the effort; during Phase II of the effort a determination of alignment in failure effects analysis modeling and actual component failure was requested. Loading factors were considered. This report is for Phase II of the effort. BSEE had questions about methods used for qualification of subsea designs for high pressure/high temperature applications (above 15,000 psi or 350 degrees F). Pressure was of particular concern.

Integrity Management Process of Tension Leg Platforms

The Contractor is to make recommendations by which BSEE can evaluate current Industry inspection processes, reporting, and monitoring system methods. In addition, the Contractor is to propose a plan of action concerning the four (4) critical areas of focus:

  1. Tendon Integrity Management 
  2. Tendon Life Extension 
  3. Fatigue of "Uninspectable" Tendon Components 
  4. Understanding the "Uninspectable" Tendon Components 

Studying "Fitness for Service" of the Sealing Assemblies and Cement System in Shallow Well Designs by Conducting Scaled Laboratory Testing, Leakage Modelling, and Risk Assessment

The primary objective of this proposal is to study "fitness for service" of the sealing assemblies and cement systems in shallow well designs by conducting scaled laboratory testing, leakage modelling and risk assessment. This project will conduct research to assess best practices and develop recommendations to BSEE and industry on the development of industry standards, regulations, and operational procedures to ensure that current cement system and sealing assemblies are "fit for service" to minimize Loss of Well Control incidents in shallow offshore applications.

Cementing Alternative Resins

The main objective of this project is determine how resins can be used for OCS well cementing to improve barrier performance. A global evaluation of the different types of commercially available resins will be conducted to determine how effective they have been when placed in offshore and onshore wells to affect proper pressure control. Global evaluation will include an assessment of any available real world data (public and/or private). An assessment of any regulations in effect on the use of these resins will be conducted among major offshore (e.g.

Thermal Shock Technology

The objective of this project was to conduct research on the thermal effects on wells and the risk of these as related to well integrity (specifically on well barriers) and potential solutions to these risks. The contractor evaluated the effects of thermal shock on OCS well integrity and identified ways to mitigate those effects.

High Pressure High Temperature Mapping of the Gulf of Mexico

The Contractor shall update the existing HPHT well data by plotting bottom hole pressure and bottomhole temperature versus true vertical depth (TVD) for GOM wells that have been drilled from 2006 to 2014. These plots should distinguish between wells at greater than 1 OOOft water depth (deep water wells) and those wells in less than lOOOft water depth (shallow water wells). Information from BSEE's Technical Information Management System (TIMS) and eWell Permitting and Reporting System (eWell) will be necessary for the update including well log.

Determination of Fracture/Fatigue-Fracture Behavior of Equipment Constructed with Cladded Weld Materials

This project will define a general approach to, and advance development of, a useful predictive computer-modeling tool for analyzing failure modes of cladded materials used in oil and gas operations. It will develop and validate a constitutive model to define fatigue and fracture behavior of cladded pipe under deep-water conditions. The failure prediction tool will predict fatigue and fracture performance of cladded weld materials in equipment used in high pressure (15 ksi) and high temperature (>350℉) (HPHT), corrosive environment (H2S, Cl, S and CO2).
