Abstract The development of Subsea Chemical Storage & Injection (SCS&I) technology is a continuation of the trend to move more of the hydrocarbon production systems subsea. This is driven by a need to make exploitation of remote resources profitable; unlock single-line long tie-backs and subsea to shore architectures, and to enable tie-ins with otherwise constrained topside infrastructure. The SCS&I System is also a significant contributor to the development of "All-Electric" subsea architecture where the umbilical is reduced to a power and communication cable only. TechnipFMC https://www.technipfmc.com/ and Total https://www.total.com/en are collaborating to develop and qualify the SCS&I technology components and system. In order to make the SCS&I technology competitive and field developments profitable, the reliability of the equipment is paramount. The HAMPRO 70V injection pump is one key component in the system for which high reliability must be ensured. The objective of the qualification program is to confirm the adequate performance of the HAMPRO 70V pump in the following areas: The reliability of the chemically exposed parts and the impact of chemical fluid cleanliness The reliability of the pump and motor rotating parts and the impact of lubricant performance The reliability of the electrical components The impact of transient behaviour on the pressure compensation system, rotating parts and electrical components Due to the similarity of design, smaller versions of the HAMPRO pump will also be qualified by the activities in the program.

This paper shows an algorithm that allows to automate the procedures of nodal analysis and flow optimization in a hydrocarbon production system. The procedure of nodal analysis is highly useful in flow wells, intermittent wells or in wells with artificial production systems. The nodal analysis evaluates a production system divided into two basic components: flow through vertical piping or production piping, and flow through horizontal piping or discharge line. For the prediction of each component's behavior, the pressure drop in each component is obtained. In order to obtain the pressure drops, nodes in different important points within the production system must be assigned; therefore, production expenses can vary and, by using a suitable calculation method, the pressure drop between two nodes is calculated. Then, a node is selected and the pressure drops are added to or subtracted from the initial pressure point or departure node, until obtaining the solution node. The results obtained when using the algorithm have allowed to update both procedures, obtaining advantages such as improvement in response time, among others. This analysis is a crucial point when making decisions related to production costs in any oil company.

Abstract This paper provides an overview of the qualification process of the highest power ESP ever installed into a hydrocarbon production system for artificial lift. The unit was selected and configured to interface with the existing deepwater offshore inflow and outflow systems without changes to the completion string or riser. The overall objective was to maximize the production capacity in terms of lift and flow rate given topsides power supply and running diameter constraints. The initial requirement was to identify a suitable supplier that could provide a hardware solution with a high technical readiness level. The team first reviewed the hydraulic performance of the existing production systems and modeled the potential for improvement with the new equipment configuration given an expected efficiency and power factor for the proposed motor. The ESP equipment was configured with components that had multiple qualification and validation testing requirements. The motor and associated high voltage connector were key differences from the existing systems. The pump design was modified to accommodate projected operating ranges including additional stages for the necessary head requirements. The new subcomponents were subjected to application specific testing to qualify the designs for operating conditions with multiple technical assurance reviews conducted by the end user and supplier company technical discipline authorities. Full scale flow testing at a dedicated facility (Gasmer) for Caisson gas/liquid separator ESP systems, and component installation stackup tests for fit and interfaces were completed to validate the performance in multiphase flow and identify hardware changes needed for the completion design and the intervention procedures. The qualification program was completed successfully, and a unit was deployed without incident, into a deepwater mudline caisson that has since been operated for live hydrocarbon production. The performance has met expectations and the unit efficiency and demonstrated capacity will allow for increased production. The use of a detailed qualification program that includes focused testing for individual system components and validation through full scale system integration testing ensures flawless deployment of technology improvements for critical well applications. The system is the highest power ESP for hydrocarbon production. It includes a novel completion design to accommodate the effective running diameter for the motor. The use of a unique shroud design to stay within running diameter constraints allowed for minor modifications to the completion string design without system changes to the riser or caisson. This was both cost effective and reduced the time needed for development and manufacturing.

The existing and prospective methods of storage of liquid hydrocarbons for offshore hydrocarbon deposits development both in the Russian Federation and abroad are considered. The conducted analysis showed extremely limited use of separately located underwater storage facilities and very significant advantages when using them as part of subsea hydrocarbon production systems. The real feasibility of them for the Russian Federation is presented.
