Wellhead Platform AWP-26 was originally developed under PTTEP Arthit Phase 2C, completed installation in 2014 and started a production from 2016 to serve gas plateau and to sustain the Arthit production. Upon depletion of AWP-26 in 2019, PTTEP Arthit Asset realized the opportunity to relocate the AWP-26 to the new prospective location in order to maximize reservoir production. In 2021, the first PTTEP Topside Reuse Project has been put into the offshore execution stage where we proud to present in this paper. The main objective of the project is to convert the originally topside design AWP-26 to suit with new prospective location and renamed to AWR-26. The topside is reused where the subsea structure (so called "jacket") is newly built as to suit with new water depth and soil parameters at the new location. The existing jacket and subsea pipeline were left as is for future decommissioning. While waiting the existing jacket to be decommissioned, tentative in 2026-2031, it is important to install navigation lights system to warn the marine to avoid collision of the remaining jacket structure. The minimal and fit for purposed structure platform is then designed (so called "navigation aid platform") was fabricated and installed onto the existing jacket for safe marine operation. It is not so simple just to relocate and make use of the existing topside to suit with the new prospective location, there were tremendous activities to be considered, starting with engineering design to make the existing topside design to be technically compatible with new process parameters of the new prospective location. Following by the early stage for preparatory works in collaboration within an internal PTTEP parties (Project Construction, Arthit Asset, Arthit Operation & Maintenance and Logistic Team), for the activities including but not limited to; platform plug and abandon, removal of flowlines, preservation of Booster Compressor, collecting the base line inspection data for piping system, platform structural integrity check, etc. In addition, to ascertain the overall weight of topside was within the safe margin and clearly defined the Centre of Gravity (CG) for the topside lifting purpose, all the vessels, tanks, containers, associated piping including the sludge removal were performed.

"Green Power Technology Playground" (GPTP) is the first demonstration project in Thailand where the whole integration system for green power technologies, ecosystem, and Internet of Things network are combined. This project is located at Eastern Economic Corridor of Innovation area (EECi) in Rayong, Thailand. The prominent concept of GPTP is Plug & Play where anyone is welcome to play, learn, and become familiar with new green power technology applications. Thus, every equipment is designed as a small, movable size in a container. It can be easily removed and installed, allowing us to learn and develop innovation for a green power ecosystem. GPTP is designed to establish the ecosystem of green energy technology. Thus, it is split into seven sections as follows:Green Power Supply: Solar roads and novel generations of solar PVs have been built and provisional areas for future renewable sources are provided.Green Power Storage and Conversion: Advanced, innovative types of battery and electrolyzer are located and green electricity is stored in batteries for the further use in nearby buildings and converted into hydrogen for other applications by the electrolyzers.Green Power Applications: Cutting-edge applications for potential commercialization to new business are provided.H2 Storage: Hydrogen is stored for the further use.Green Backup Power: New generations of fuel cells are provided.H2 Utilization and Carbon Capture Utilization: The plug and play modules for ammonia and urea production and CO2 refrigeration packages are assembled.Smart Energy Management System: By using Internet of Things, all elements in the playground are controlled via cloud. Thus, any related party can access information and monitor the system from anywhere and anytime. As PTTEP (Main Stakeholder) intends to build innovations for new energy technologies and scale them up for commercialization, the investment in a demonstration project is needed. Investing in a large scale, not know-how, less matured green power technology applications can impose a high risk. Thereby, GPTP will accelerate this step by developing staff’s competency and resource capability. Thus, the main stakeholder can learn how to produce and operate from a small module and quickly scale up for commercialization.

Shale oil in Ordos basin, China, is being developed using horizontal well and volume fracturing. Elastic energy, dissolved gas expansion etc. are the main driving forces for fluid flowing from matrix to horizontal wellbore. However, flow mechanism varies greatly when hydrocarbon flows from matrix to artificial fractures and then to wellbore, due to huge differences in the sizes of flow channel, from nano-scale pore-throat in matrix to meter-scale channel in wellbore. Thus, a reasonable mathematical description of the structural characteristics of complex fracture networks is important for an accurate productivity prediction model of a horizontal well. In this paper, a physical model was first built dividing fluid seepage area into three sections and five small zones, which are horizontal wellbore zone, highly transformed zone, weakly transformed zone, drainage zone in matrix and the non-drainage zone in matrix. Joukowski transformation was then introduced before a mathematical solution was deduced, where law of equivalent seepage resistance and material balance method were applied. Then mathematical model of seepage in five different zones were built based on the solution considering different flow patterns, threshold pressure gradient and stress sensitivity in those zones. Productivity equation of multi-section-coupled seepage flow in three sections was deduced afterwards and came up with a fast calculation method to predict productivity in horizontal well with multi-scale nonlinear characteristics by solving analytical solutions for multistage mathematical models. The method has been applied to simulate dynamic development performance in 67 horizontal wells (have been producing for over 3 years) in Qingcheng oil field, Ordos basin, China, with an 82.01% of accuracy. The developed simulation model is expected to be applicable not only in the prediction of development performance in horizontal wells in shale oil and gas reservoir but also in other unconventional reservoirs such as carbonate reservoirs. The process may shed light on the ways to increase the total productivity of oil and gas recovery in hydrocarbon industry.
