Transcription

1 Integrity Workshop Well & drilling, Subsea & pipelines 26 th October 2015, Rio de Janeiro Windsor Atlântica Hotel Ensuring integrity during operations and in the lifetime of facilities and installations have the highest priority in the Oil and Gas Industry. ANP is now launching two new regulations on Well and Drilling and on Subsea and Pipeline Integrity. INTSOK in cooperation with Innovation Norway and with institutional support from ANP and the Norwegian Consulate General are pleased to welcome you to this workshop where these regulations will be presented, where oil companies will share how they prepare for implementing the regulations and INTSOK partners will present technologies and solutions corresponding to the new regulations.

2 The new regulation on Well and Drilling Integrity Mr. Carlos Agenor Onofre Cabral Regulatory Specialist The new regulation on Subsea and Pipeline Integrity Ms. Priscila Raquel Kazmierczak Regulatory Specialist Addressing the subsea and pipeline integrity challenge in Petrobras Mr. Mauricio Diniz General Manager Subsea Engineering Addressing the well integrity challenge in Statoil Brazil Mr. Leonardo Malouf Completions Engineer Statoil is and has been the main player on the Norwegian continental shelf, operating a myriad of assets. Due to this privileged position as an operator in Norway, the company has been following the Norwegian standards for quite a long time, adapting and evolving to continuously meet regulations. In that sense, the company made its own internal requirements based on the NORSOK D-010, which has been steering operations since then. The presentation held by Statoil in the seminar will shed light over how the company has structured itself to meet the well integrity challenges. The efforts towards documenting and managing well integrity status will be addressed, as well as how iwit (Statoil s official tool for well integrity) compiles all relevant information in a simple web based interface.

3 How structured is the subsea market to support the oil companies in meeting the new regulations Mr. Paulo Martins President Workforce competence for the drilling industry Mr. Tony Cox Regional Director - Brazil, International Association of Drilling Contractors tony.cox@iadc.org This presentation will include a brief introduction of who the IADC is and what is the mission of the association. The Macondo incident clearly indicated the need for the drilling industry to be able to demonstrate the competence of personnel working on our units. Since then more and more regulators, BSEE, UK HSE, ANP and others, are introducing legislation that requires processes and documentation to be in place to meet this need. The presentation will provide some basic detail of three relevant IADC global initiatives and one from the IADC North Sea Chapter. 1. The Knowledge Skills and Abilities initiative. 2. The IADC Guide to establishing a Competency Program. 3. Competence program accreditation. 4. Demonstrating competence of third party personnel working on drilling contractors site.

4 Adapter for ancient THS with VDV vs XMT with AIs valves Mr. Mauricio Barbosa First Chief Engineer, Subsea Engineering To eliminate, reduce and control operating risks, Aker Solutions has developed a device that will allow the installation of Christmas trees as per ET PPC-001 (Global XTs) on PABs (Production adapter base or Tubing Head Spool) as per ET PPC-016. PABs that were developed based on this ET have tubing hanger with a VDV (double seal valve) that have been banished by ANP; these valves do not allow seal test before operation to remove XT. If proposed equipment developed by Aker Solutions is used we can reuse the old PABs simply landing the new equipment on top of the old BAPs allowing the use of new XTs (Post-salt standard concept). The main contribution, besides to mitigate of operational risks, the costs will be lower, as well we can maintain the old equipment installed, PAB and tubing hanger, carrying only an intervention to remove the old XTs and landing the adapter. The purpose of this article is to demonstrate the risks related to the old concept with VDV and compare them with the adapter design, with which we can eliminate unsafe operating conditions. Unique technology for 3D integrity monitoring of subsea pipes Mr. Trond Olsen President, ClampOn Inc. trond.olsen@clampon.com This paper provides background information about ClampOn's development of its subsea corrosion-erosion monitoring system, an explanation of the measuring principles used, and explains how combining several technologies and principles allows us to accurately monitor changes in wall thickness loss in subsea installations and fulfil operators' need for continuous condition monitoring of subsea pipes. ClampOn has developed a system that not only provides direct measurement of and important information about ongoing corrosion and erosion, but also offers highly accurate high-resolution 3D imaging of subsea pipes securing pipeline integrity.

5 Case Study: Well integrity and QRA of the shut-in wells or wells producing with degraded barrier Mr. Tobias Vieira Alvarenga M.Sc Head of Section, Asset Risk Management An independent approach to develop a decision support tool to prioritize and evaluate if further actions to reduce the risk are required. This case allows to develop new tools and processes to integrate well integrity with quantitative risk assessments, resulting in a more accurate basis for a risk-based decision making. Roxar downhole wireless PT sensor system Mr. Romulo Emerik Application and Sales Consultant Romulo.Emerik@Emerson.com Annulus B allows the continuous monitoring of pressure and temperature in the B annulus of a sub-sea well. The system consists of a casing mounted Roxar downhole Transponder Carrier with integral antenna and PT sensor. At the tubing side a corresponding Roxar downhole Reader Carrier is mounted with an antenna and reader section that is connected to the standard Roxar Integrated Downhole Network (IDN) system. Data and power to the PT sensor is transmitted wirelessly between the two antennas. telthe Roxar IDN network is connected to a dedicated network controller card (DHNC) at the subsea installation. PT data are thus monitored continuously to surface with sampling rates up to every second. The system is designed for a lifetime of minimum 20 years in conditions up to 150 degc and psi. The Roxar IDN network is capable of transmitting data from up to 32 sensors simultaneously from any position in the well. The Roxar downhole Transponder Carrier system is fully sealed from factory and has no potential leak paths. The electronics are not activated until power is sent via the Roxar IDN network from surface.

8 How software solution enables to meet well integrity management objectives and regulation compliance Mr. Vincent Geyl Well Integrity Expert An independent approach to develop a decision support tool to prioritize and evaluate if further actions to reduce the risk are required. This case allows to develop new tools and processes to integrate well integrity with quantitative risk assessments, resulting in a more accurate basis for a risk-based decision making. The well integrity discipline has considerably developed over the last 10 years, turning from a few concepts to a full approach on the well's life cycle. Being at the interface of several disciplines, organization and people, there is a clear difficulty to demonstrate and document an acceptable well integrity and safety level for operators. The Exprosoft has provided well integrity reliability data and risk assessment techniques since the early 90's. Today the company is providing two main software solutions: - Wellmaster reliability management system (RMS) providing unique reliability data for decision making, risk assessment and safety analysis, started more than 30 years ago. - WellMaster Integrity Management system (IMS), giving operators the tool to meet their Well Integrity management objectives during the operational phase.

9 Condition and performance monitoring of subsea systems Mr. Paulo Roberto Machado Jr. Life of Field Engineering Manager Production Monitoring has historically been the operators' main focus, not monitoring the plant condition in itself. Knowing how a well produces and how the reservoir performs have been seen as more important than knowing the integrity of a downhole pressure transmitter or a production choke. If production critical equipment fails the corresponding well is closed down and the failed equipment is retrieved and switched. Subsea production equipment is typically built as retrievable modules which can be changed out by an intervention vessel. This opens for maintenance planning where monitoring the equipment can contribute to the decision for when to retrieve the equipment. Knowledge about the condition is limited by the installed instrumentation and the available communications bandwidth up to the topside control system. While the topside equipment easily can be retrofitted or instrumented for condition monitoring, that is not easily done subsea. As subsea equipment and instruments become more advanced, more functionality is added which again increase the number of potential failure modes. Many of these failure modes are hard to predict and troubleshoot. Wrong use or incompatible operating conditions are the cause for many failures, but detecting those during production can be difficult. This can lead to maintenance campaigns where the wrong equipment is retrieved or where the wrong decisions are taken. Condition and Monitoring systems have been developed to meet the requirement for operational and maintenance excellence. It combines continuous monitoring of the system with a historic database that will enable trends and deviations to be identified. The system will mainly provide the operator with a warning when components start to deteriorate. This in turn will allow pinpointing problems and enable corrective action to be planned resulting in minimum disruption to the production.

10 Wellhead integrity monitoring instrumentation: Options and benefits Mr. Lauro Massao Yamada Da Silveira Engineering Manager, KOGT Brazil Despite many technical challenges, technology nowadays has been able to provide all players in the offshore oil & gas industry with mechanisms for safer and more reliable operations. One of these mechanisms is monitoring systems and, more specifically, wellhead integrity monitoring. Within this area, a key aspect is to know the loads and deformations the wellhead - which may be thousands of meters below sea level - is being submitted to. This knowledge leads eventually to the capability of a much more accurate control of the wellhead mechanical integrity. In essence, a monitoring system has to be able to measure certain parameters, transmit and post-process this data to convert it into an useful engineering information. This paper will then present and discuss the several options on measurement, communication, power supply and data processing related to the wellhead integrity monitoring as well as present a case study of a real application of such monitoring system within a cooperation between Statoil and Kongsberg Oil & Gas Technologies (KOGT).

11 Risk assessments/reliability analyses important tools in establishing barrier requirements and determining barrier status Ms. Angela Hayashi Energy Consulting Manager When we think about drilling activities is natural to think about safety operations and associated barriers to prevent and/or mitigate any unwanted event that might happen. The concept of barrier means that a group of safeguards and controls selected to prevent the realisation of a hazard are in place, in other words means that technical, operational and organisational elements intended to prevent and mitigate a deviation are effectively part of the system.during drilling operations at least two independent barriers shall be available in order to prevent hazardous events like an unintentional flow from the well. The main principal of ensuring that two barriers at drilling operation are always in place is simple, but in practice quite demanding. Each barrier includes several barrier elements. At the various stages of operation, the elements may change in the way they together form a barrier. There is also a change in terms of operability and availability of each element as a drilling operation is conducted. Accordingly, the acceptance criteria for each barrier element need to be both specified and then verified for several scenarios. The paper will discuss the bowtie methodology and in particular the risk assessments forming the basis for the analysis and documentation of barrier integrity.

12 Mud spill protection (telescopic joint) with packer monitoring system Mr. Pedro Alcântara Nunes Neto Head of Internationalization As a result of Norwegian authorities demanding zero spillage from drilling operations, Sub Sea Services have developed a mud spill protection system that monitors and collects the mud fluid coming from the Telescopic Joint packers. Undetected packer wear or failure can result in accidental spillage of drilling fluids into the environment. The system s continuous circulation ensures constant lubrication and cooling of the packers, and since the levels of the fluid is constantly monitored, the system acts as an early warning system for spill prevention. If a packer fails, the system is designed to alert the drilling control room, energize the back-up packer, collect the mud and discharge the contents into rig waste. Use of well barrier illustrations Mr. Tore Fjågesund Founder / Technical Director tore@wellbarrier.com A practical presentation will be made showing the benefits of preparing well barrier schematics in line with the two-barrier-philosophy as described in Norsok D-010. Mr. Tore Fjågesund from Wellbarrier, who co-authored the standard, will present the Wellbarrier Illustrations Tool, a web based solution, enabling users to prepare well barrier definitions in a quick and high quality manner. Use of high quality well barrier schematics will help all stakeholders see more clearly what they are up against, thus contributing to safer wells and operations.
