This is a great way to learn the expectations of RRD on how to evaluate this critical pathway.

Analyzing Well Flow Capacity The well flow capacity is mainly dependent on the flow inside the reservoir (IPR) and the flow in the tubing and surface flowlines Analyzing the IPR and OPR will help us to determine what ESP we would need to achieve a desired liquid production rate. demonstrates the main working principle of ESP system It is important to note that if reservoir pressure is greater than bubble point pressure Productivity Index (PI) is a constant and hence the IPR is a straight-line and Darcy law can be applicable. If the reservoir pressure is smaller than the bubble point pressure than the IPR is no longer a straight-line; instead it is a curve. In this case, Vogel’s equation (or any other multiphase IPR correlations) can be used to describe for the IPR and OPR of oil well Without a pump the well is producing naturally at an equivalent liquid rate of Qnf e . For this well to produce at higher liquid rate (desired production rate), an ESP with a total pump head of H pump ¼ DP pump qf g is needed to overcome the hydrostatic pressure, friction inside the tubing, and wellhead pressures at the surface.

Dear SPE Well Integrity Technical Section members and others, register yourself for webinar with special topic "Regulatory Well Integrity Requirements for CO2 Injection Wells and Legacy Wells Assessment on Norwegian Continental Shelf"! This webinar will focus on the regulatory and technical framework for CO₂ injection and storage wells on the Norwegian Continental Shelf. Key regulatory measures, such as the CO₂ Safety Regulations (§11), focus on assessing well integrity for both active and legacy wells, addressing potential risks like corrosion, cement degradation, and pressure changes associated with CO₂ storage. Standards like NORSOK D-010 guide the design of well barriers to ensure long-term safety and containment, in the Norwegian continental shelf. The presentation highlights the challenges unique to CO₂ wells compared to traditional petroleum wells, including the handling of supercritical CO₂ and its implications for well materials and monitoring. Case studies from selected fields demonstrate the use of 4D seismic technology to monitor CO₂ migration and ensure containment. Collaboration between industry and regulatory bodies is emphasized as essential for advancing carbon capture and storage (CCS) technology while maintaining high safety standards in Norway. Webinar will be moderated by Ainur Kaken and topic will be presented by Nina Ringøen https://lnkd.in/dP36G5YB

VFM/Sudden Water Production in a Deep Water Oil Well. Oilfield Data Services Inc. (ODSI) was brought in to diagnose the root cause(s) of sudden water production (zero to 4000 BWPD almost overnight!) in a deepwater subsea GOM oil well. Using the tree gauge and the downhole gauge to perform multi-phase rate calculations, independently of the MPFM. ODSI also performed automated PTA and additional reservoir evaluation work to determine that produced water was extraneous and would not affect the recovery from the reservoir, concluding that an intervention was not warranted. The findings emphasize the importance of accurate meter calibration and thorough reservoir evaluation to understand unexpected production behaviors, highlighting the necessity of integrating real-time data analysis for effective reservoir management and decision-making. ODSI saved the client $130 MM in well intervention costs by conducting this investigation. Do you have similar experience?

🛢 Reservoir management is challenging. What happens when reservoirs have similar oil and water viscosity?   In the complex world of oil production, managing the reservoir flow of different fluids is crucial. When the viscosity of water and oil are the same, traditional inflow control devices struggle to differentiate between the two, leading to increased water production and reduced oil production & recovery.   The AICV® is both density and viscosity sensitive, ensuring precise control of the fluid flow. The technology autonomously adjusts to varying conditions, optimizing oil production while minimizing un-wanted water and gas.   There are several different AICVs for different reservoirs, ranging from ultralight oil 0.25 cP to heavy oil of >3000 cP.

In our academic studies or university education, We have been taught that the optimum production system will have the lowest BHFP (Pwf) as to have the maximum reservoir deliveribility, production efficiency and therefore, the max. flow rate. But the fact and reality is, we can't decrease the BHFP but we try to decrease all the amounts of back pressure which is applied on the wellbore pressure in terms of using different approaches including: (1)reducing pressure losses in the tubing or production conduit, (2)flow assurance operations/applications and (3)reducing the THP or FLP e.g. the use of transfer pumps @ OGMs and wells tie-in points to have a greater delta P for having the highest Q possible from the system

🦉 It's time for some #WednesdayWisdom with Oilfield Technology 💡 This week we are looking back at an article from our Autumn 2023 issue, where Ming Yang, TÜV SÜD, discussed the different methods used to measure oil-in-water, and the rise in online analysis techniques. 💬 "Measurement of OiW is a specialised subject. Whilst reference methods are vital in OiW in definition and compliance monitoring, alternative methods are also important for operations and convenience. Use of online OiW analysers, which are part of alternative OiW measurement methods, has increased in recent years for operations and for discharge reporting purposes. Online analysers offer many benefits by providing minute-by-minute information, reducing the need for manual sampling and analyses and potentially offering more accurate OiW discharge information."
