Field developments, from greenfield to mature field rejuvenation are challenging and there are various possible options. Attention to production risks and flow assurance issues are key in determining what type of production concept that is optimal for any field in question.Sand production issues can have a severe impact on any field architecture but this can be remediated by the use of sand removal technologies. With the advances in separation technology and the feasibility of using subsea separation solutions, there can be many benefits in terms of reducing erosion and clogging risks as well as enabling prevention of gas hydrates. Subsea separation can be an important enabler for field development decisions.Some key technologies for subsea separation solutions, such as gas/liquid separators, desanders and hydrocyclones have been qualified for subsea applications and have been proven topsides. Gas/Liquid separation can be part of subsea solutions aimed to minimize formation risks of gas hydrate in the risers. Ongoing development work can contribute to reduce complexity and total project costs for field developments.Adequate technology qualification for new technology should be done utilizing a large-scale realistic conditions flow loop.

“…The collected solids are removed periodically by jetting and flushing (a spray nozzle or cyclonic type). Gravity separation is effective at removing particles with a diameter of 75-150 microns (Fantoft et al 2004, Olson et al 2014, Rawlins 2016). S-4: Inertial Trap.…”

Sand is a limiting design factor for facilities in terms of operability, throughput, and maintenance. These effects are more critical when dealing with subsea processing due to the equipment access and risk exposure. Technologies for erosion management, sand separation, and solids disposal are well proven for surface facilities. For example, the wellhead desander, located upstream of the choke, effectively separates sand from the multiphase well flow and can be marinized for subsea use. However, the crucial question is "What to do with the sand?" This white paper provides a focal point for the discussion on sand management in subsea processing. The broad categories for dealing with sand include neutralization of the effects, improvements in conventional design, and separation with disposal. These categories have been analyzed based on the conventional design, treatment of the solids, and removal of the solids. More than thirty discrete treatment routes were surveyed, including conventional production limits, flow path modification, chemical treatment, sand cleaning, mechanical attrition, slurry fracture injection, and accretion disposal. Many of these technologies have analogues in other particulate processing industries that can be adapted to upstream oil and gas production. This work is part of ongoing research in Facilities Sand Management with the goal of improving the hydrocarbon recovery through inclusionary sand production.

In recent years, various operating companies have been working on the processes of "Simplification, Standardization, Automation, Digitalization, and Optimization in several elements". To achieve this, there are tremendous subsea technology developments going on all over the world in many areas such as; design in terms of size and weight, improvement in reliability, advanced materials, flow assurance, digital tools, real time condition monitoring and control, installation and operation. The development of Subsea technology continues to be an important part of subsea field development projects to reduce the life cycle costs, increase recovery, provide solution to long tieback problems and challenges. PETRONAS ("the Company") is pursuing an Upstream Life Cycle Cost (CAPEX/OPEX) reduction approach under the Facilities of Future (FOF) program and mission called "Subsea Factory". The FOF target is to reduce Upstream life cycle cost by 40% starting from 2025 and Subsea Factory is one of the enablers to contribute to the reduction. There are four primary technologies focused on Subsea Factory: Subsea Separation, Subsea Multiphase Pump, Water Injection and Subsea Storage. The Subsea Multiphase Pump is one of the prioritized technologies for Subsea Factory to contribute to a 40% reduction. Subsea multiphase pump technology has great potential to reduce the CAPEX/OPEX and increase oil recovery, but due to the high equipment cost, huge topside space requirement, reliability and operating issues become very challenging and limit its application to operating companies. The Company collaborates with FASTsubsea AS on a Joint Industry Project to develop and qualify "the World first All Electric & Topside-less Subsea Multiphase Pump Technology". The uniqueness about this technology compared to commonly installed subsea pump is that it requires much less topside space as there is no need for variable speed drives or barrier fluid hydraulic power units. This paper describes the qualification and application of All-electric & Topside-less subsea multiphase pump technology in the Company - Subsea Factory mission, including: pain point with conventional subsea multiphase pumpthe Joint Industrial Project initiative with respect to technology development to pilot test to maturityimplementation of this technology and value creation in upcoming field development projectthe case study and potential of this technology for the Company future field development project
