It will discuss the relevance of these developments to oil and gas operations and to other energy sectors.

Roger Lott, Chair of the IOGP Geodesy Subcommittee

Roger Lott is chair of the IOGP Geodesy Subcommittee. He has professional land and hydrographic survey qualifications from the UK. He is a former chief surveyor and survey technical advisor for bp, for which he worked for 30 years. During this time he worked in Europe, North and South America, China and south east Asia including several business visits to Indonesia. Roger is the co-chair of the Open Geospatial Consortium (OGC) coordinate reference systems working group, and a member of an International Association of Geodesy working group that, in conjunction with OGC, has developed a standard deformation model functional model (DMFM) and an associated exchange format for gridded geodetic data (GGXF). He is co-author of an introductory text book on Datums and Map Projections (for remote sensing, GIS and surveying).

Steadily increasing demands for integrated geospatial data is perceived by numerous businesses including oil & gas exploration & production (O&G E&P) as a major challenge This becoming even more critical  as national regulation is stringently enforced through Presidential Decree No. 9 Year 2016 according to One Map Policy (OMP), in the form of the Indonesian Geospatial Information Network (JIGN).

To address this challenge, PERTAMINA is developing an agile system of geospatial data integration, namely ‘ONE MAP’, to establish a corporate geodatabase model, including a mechanism to integrate  existing enterprise GIS which are being managed in regions & zones. ONE MAP is also ready to comply with JIGN, in the frame of O&G E&P’s GIS.

In tandem with this effort, SKK Migas is developing an innovative O&G E&P GIS, called ‘SPEKTRUM’ to replace conventional data collection methods and address the immediate demands of stakeholders. Success is achieved when ONE MAP is able to display as a reference on SPEKTRUM, with a target of  further interconnection to SPEKTRUM by  2025.

In parallel with ongoing collaboration efforts, the scheme is already being applied in a 3D Seismic Survey of Bird’s Head West Papua, which encompasses various different types of forest, and has a challenging permitting schedule with the Ministry of Environment and Forestry (MoEF).

As the part of the operating strategy, the area is then overlaid to SIGAP, which is a MoEF geoportal designed to manage 95 forestry geospatial information themes. 25 of the themes are already integrated to the OMP portal. The overall objective is to facilitate convenient data sharing, whilst adhering to  security and confidentiality requirements. The collaboration is designed to demonstrate a proven system in accordance with JIGN requirements, and to optimize exploration within a remote area in order to support energy supply sustainability.

A hydrographic datum, or ‘sounding datum’, often officialised as ‘chart datum’, is the reference plane for depths on bathymetric maps or nautical charts. It is conventionally defined via permanent tidal gauging stations, and used to reduce observed depths from hydrographic surveys. It is also realised through physical markers or ‘bench marks’ using in coastal construction, and used as the vertical reference during the oil and gas life cycle (exploration, development, operation and retirement).

Issues arise when an area of interest is not within the vicinity of a tidal gauging station, such as in remote operations. Practical approaches have been attempted to manage such issues, and resolve the need for vertical referencing with reasonable accuracy, i.e., within decimetres. Scientific work has been undertaken recently to improve accuracy by applying the ‘hydrographic separation model’ (HSM), which provide a seamless reference plane at sea by defining any height above the reference ellipsoid.

The objective of this paper is to discuss the role of HSM in improving the reliability of offshore vertical referencing – initially via a conceptual description, followed by the technical requirements for  materialization of HSM. Relevant cases are examined, highlighting operational design of a hydrographic datum at sites where environmental constraints challenge networking between conventional tidal gauging stations. In addition, the existing infrastructure in the Indonesian archipelago is assessed to determine vertical reference options and a proposal for future development.

Full implementation of HSM is expected to benefit all marine stakeholders. Within the oil and gas sector, benefits accrue via reduced HSSE exposure, better operational cost efficiency and a lower carbon footprint. Similar and broader venture advantages are seen for other stakeholders, including renewable energy source development.

Tangguh LNG, located in West Papua, is planning construction of additional onshore and offshore facilities as part of its Tangguh 3 train business development. Onshore, construction involves tie-in to existing infrastructure that may require ground disturbance activities.

The complexity of the existing onshore infrastructure, especially underground services, introduces a known risk, particularly during ground disturbance activities. Although most of underground asset locations are available via as-built drawings, data accuracy needs to be verified prior to every ground disturbance. Reliable underground asset mapping is key to understanding and eliminating risks associated with ground disturbance.

A Ground Penetrating Radar (GPR) was used to map underground assets including pipelines, cables, foundations, etc across the planned construction site of approximately 20 hectares. Due to the large area requiring to be covered, and to provide enough information on the location of the buried assets, acquisition was conducted using area-based scanning, where the GPR is set to a 1-5m scanning interval.

The GPR data was interpreted to create an underground asset map. The result provides good general understanding of the location of underground assets for planning purpose, however, area-based GPR data is not good enough to be used for specific ground disturbance activity. For this, more robust and high resolution GPR scanning is required over the area of interest, prior to each ground disturbance activity. This project implementation underlines the importance of geomatics supports in delivering not only better identification of existing facilities, but also reduces the underlying operational HSSE footprint by reducing chance of incidents, and improving overall operational efficiency, for example through better spatial awareness of buried hazards. In turn, this strongly support the security of energy supply.

Ahmad Basyar, Survey Specialist, BP Indonesia

Basyar is a survey specialist for bp Asia Pacific Region with over 15 years of experience in the land and hydrographic survey industry.

His current role provides onshore and offshore survey and positioning technical support and management to many internal stakeholders and customers, across bp’s Exploration, Sub-surface, Wells, Projects and Production businesses.

Over the past decade, the consumption of renewable energy has increased, without decreasing the demand for fossil fuels. Rising global energy development has impacted exploration and production activities, not only in terms of sourcing suitable operational support, but also via more stringent carbon emissions targets. Due to high demand, human resources and service providers typically are more inclined to participate in the new energy activities. To balance these impacts, alternative technologies are being identified that can reduce dependency on human resources and at the same time decrease HSSE risk exposure.

Motivated by this, various remote and autonomous operation methods are being implemented. These include expanding on Uncrewed Aerial Vehicle (UAV) applications and identifying suitable and cost-benefit uses of Autonomous Underwater Vehicles (AUV). It also involves introducing new technologies to the market, notably Uncrewed Surface Vessel (USV) services, and remote positioning. USV technology is relatively new to PETRONAS and Malaysia, and has a lot of potential to address current operational challenges. However, unlike UAVs, from a regulatory perspective there is no specific process to govern its utilization and implementation. This presentation shares some of the effort that led to success in the deployment of remote and autonomous systems, including the first commercial USV implementation in Malaysia for O&G applications.

To be efficient in the upstream business during the energy transition, we must embrace automation. This can be achieved by implementing advanced technologies such as AI and automation systems to streamline processes, improve operational efficiency and reduce costs. In this paper, we present two case studies that enhance efficiency, cost-effectiveness and data management within the industry.
The first case study highlights how the Seabed Survey Data Model (SSDM) is supporting automation, to enable accurate data delivery from contractors to operators. Utilizing industry-standard data models, an automation workflow was developed to streamline data management processes. This improves contractor-operator interactions, which in turn drives cost and productivity efficiencies and improvements in the delivery of accurate and trusted data.
The second case study centers around Notices to Mariners (NTMs) and showcases how AI has been used to revolutionize hazard analysis and mapping processes. Utilization of AI technologies improves how information can be searched, extracted, spatialized, and mapped, in turn leading to more efficient hazard analysis. Automated processes enable better decision-making and improved safety.
Both case studies are aligned with the objective of digital transformation within the industry, and highlight the capability of automation and AI in enhancing efficiency in upstream business.

Offshore South East Sumatra is a field with many historical-oil spill events. Satellite monitoring provides an option for daily coverage and early warning of oil detection and pollution identification. Satellite monitoring includes RADAR that images through cloud cover and at night. This results in consistent and reliable images both spatially and temporally. Satellite imagery can cover huge areas and provides a common overview that cannot be obtained on site, and can be used by both On Scene Commanders and remote-based decision makers. The satellite service provider should deploy a toolbox of options such that operational redundancy and a secure service is maintained. Fast delivery of satellite based oil detection and source identification can be proactive both via planned daily monitoring and as part of an emergency response plan, by using rapid tasking of satellites. Oil slicks detected via oil dampening of sea surface roughness can be augmented by satellite RADAR and other ancillary data such as AIS to help identify the spill source.

The system described above includes near-real-time imagery, providing quick analysis of potential oil slicks. Source and oil drift data is transferred for display in PERTAMINA’S GIS (One Map GIS). This can then be used by decision makers to visualise oil spill size, speed and trajectory, to manage actions such as boom and clean up deployment systems.
Full implementation of such a mechanism not only helps to identifies corporate potential risk toward but also supports compliance with license to operate regulations.

Restoration of the mature Langsa Oil & Gas Complex in the Malacca Strait is a crucial decision for PERTAMINA management. The quality and extent of existing data needs to be assessed from HSSE, economic and technical perspectives, in order to define an appropriate strategy for new data acquisition and processing requirements. In turn this supports optimal re-activation and re-production of reserves.

GIS plays a crucial role in managing, integrating, visualizing and analyzing the disparate data types required for this project. Data types include subsea structures visualized using 3D ROV video modelling, pipeline cathodic protection and wall thickness data, seabed profile and imagery captured in SSDM, and pre-existing subsurface geology and geophysical datasets. Underlying legacy geodesy parameters and configuration also needs to be re-confirmed.

Integrations in a GIS framework is complex. Several mechanisms have been applied to allow data to be presented in a web-based application that provides comprehensive visualization and improved data accessibility. This application enables users and management to contextualize the complex geospatial relationships of the subsea environment and subsurface data.

Implementation of the full extent of geomatics skillsets, from geodesy, survey operations & data acquisition to geospatial data management, visualization and analysis will benefit both the technical and management community by allowing rapid and integrated access to relevant trusted data and information. This in turn will inform appropriate recommendations on the re-commissioning strategy.

Since 2021, Fugro Australia has been completing commercial projects utilising the Fugro Maali, a 12m Uncrewed Surface Vessel (USV). Such was the success of the Maali that earlier this year Fugro took delivery of our second USV, the Fugro Kwilena. Both USVs are now operating 1500km north of the Perth Remote Operations Centre (P-ROC). Key to the success is Fugro’s bespoke satellite communications and data compression technology to ensure the USV and its associated eROV (electric ROV) can be operated with minimal latency. With this configuration, operators maintain USV control in real-time as if they are operating from a conventional vessel bridge. Operations in high-risk environments is enabled through layers of redundancy in all vessel systems. Implementation of this technology has provided significant improvement in the HSE footprint, by relocating personnel from offshore to onshore, and also results in a 95% reduction in the survey carbon footprint, when compared with traditional methods, and HSE exposure is also significantly reduced.

The Mahakam area is one of the main oil and gas concessions in Indonesia, covering seven fields across various environments – land, swamp/nearshore and offshore. A combination of 3000 existing wells and a program of drilling over 100 new wells per year creates well collision, shallow geohazard and well-site clearance and maintenance risks that have strong geospatial components, and need to be managed carefully by the Operator, PERTAMINA Hulu Mahakam (PHM). High accuracy centimetric horizontal positioning is essential, including the utilization of WADGNSS

Using the existing datum transformation (EPSG: 1838), a discrepancy of about 84 cm is apparent between observed data (using GNSS data considered to be on ITRF93 epoch 1995.2-PHM) and the local datum (EPSG: 6631). In order to realize the full accuracy of modern positioning technology, the discrepancy between the WADGNSS service-provider reference frame and the local datum needs to be resolved

A joint study determined new time-independent Helmet-7 datum transformation parameters, reducing the difference to approximately 10 cm. With a crustal deformation rate of around 3 cm a year in the Mahakam area, the recommendation is to update transformation parameters regularly. This provision of accurate position derivation is seen as supporting improvements in HSSE, cost reduction and overall sustainability of energy supply.

PERTAMINA EP (PEP) currently manages several fields in the West Java Block, with a development focus to maintain and enhance hydrocarbon production. Real-Time Kinematic Networked Transport of RTCM via Internet Protocol (RTK NTRIP), also referred to as Long Range RTK (LRTK), is proposed to support development, by delivering not only accurate & more reliable positioning, but also to reduce HSSE risk and improve cost efficiencies and the operating carbon footprint.
A trial test is being conducted to assess LRTK capability to achieve both the required accuracy and Internet Provider connectivity & coverage reliability. The main objective is to replace traditional methods currently used for PEP survey, positioning and mapping activities, which requires many mobile base stations, as well as precise point positioning RTK (PPP-RTK) subscriptions for offshore operations.
The test was conducted on the Pamanukan coast using two base stations in the Subang Field (35.55 km range) and Jakarta (112.64 km range), using Internet Provider towers in the test area. The test identified that LRTK operated well, delivering acceptable accuracy up to ranges of 50 km, but for distances over 50 km, un-resolved phase ambiguities still require further assessment.
Around 80% of energy business data (traditional and/or renewables) is spatially referenced. Bearing this in mind, despite its ongoing assessment, this project underlines the impact that suitable geomatics input can have on operations, in supporting the reduction of HSSE, technical, financial & business risk, and in contributing to the sustainability of energy production.
