This document outlines TOHO 9000, an oil additive that extends the life of engine oil and other lubricants. It works by preventing small oil particles from binding together into larger particles that could clog filters. Instead, micro-sized TOHO 9000 particles attach to oil particles and disperse combustion byproducts, maintaining oil quality for 12 times longer than without the additive. This extends equipment life, lowers costs through reduced oil and filter usage, and cuts pollution by improving fuel efficiency. The document provides details on TOHO 9000's history, capabilities, and benefits to fleet operators.
Potassium formate brine has been successfully used as a drilling and completion fluid in hundreds of high-pressure, high-temperature gas wells since 1995. It has allowed for improved economics by reducing well delivery times and costs while improving safety. Key applications include drilling reservoir sections, completions, workovers, and suspension of wells. Countries where it has been used extensively include Germany, Norway, the UK, Pakistan, Saudi Arabia, and others. Its use has helped develop major gas fields like the HPHT fields in Northwest Germany and the world's largest gas field, Kashagan in Kazakhstan.

SPE 199286 - Profiling the Production Performance of Five HPHT Gas Condensate...John Downs
1. The document discusses production performance from five high-pressure, high-temperature gas condensate wells in the Kvitebjorn Field in the Norwegian North Sea that were drilled and completed using cesium formate drilling fluids.
2. Logging data obtained using cesium formate brine showed improved reservoir quality, leading to a 33% increase in estimated hydrocarbon reserves. Actual cumulative production from the field has matched or exceeded revised reserve estimates.
3. Cumulative production from the initial five wells after 14 years is now higher than the original reserves projection for the entire field, demonstrating the benefits of using cesium formate fluids for drilling and completion.
SPE 145562 - Life Without Barite: Ten Years of Drilling Deep HPHT Gas Wells ...John Downs
The tradition of using barite to increase the weight of drilling fluids dates back to the early-1920’s and, while it has been of great benefit to the oil industry over the past 90 years, it has also caused some chronic and persistent well construction problems along the way. These problems, which are very familiar to drillers, include well control difficulties, stuck pipe incidents and formation damage.
The oil industry has known since the 1970’s that replacing barite with suitable non-damaging solutes in reservoir drill-in fluids is an effective way of reducing formation damage, simplifying operations and eliminating the need for expensive formation damage by-pass operations. The development of brine-based drill-in fluids opened up the opportunity to connect more effectively with hydrocarbon reserves by allowing the construction of long high-angle reservoir sections completed in open hole. Despite the advantages on offer, the industry was unable to exploit this novel technology in deep HPHT gas field developments until the mid- to late-1990’s when drill-in fluids based on potassium and cesium formate brine became available in commercial volumes.
Cesium formate brine was first used as a reservoir drilling fluid in the Huldra gas/condensate field in the North Sea in January 2001, and has now been used to drill a total of 29 deep HPHT gas wells. The information presented and reviewed in this paper confirms that the use of potassium and cesium formates as the sole weighting agents in reservoir drill-in fluids has enabled operators to enjoy the full economic benefits of creating low-skin open-hole completions in deep high-angle HPHT gas wells. The review also concludes that the use of these heavy formate brines as drill-in fluids over the past 10 years has facilitated the safe and efficient development of deep HPHT gas reserves by:
• Virtually eliminating well control and stuck pipe incidents
• Enabling the drilling of long high-angle HPHT wells with narrow drilling windows
• Typically reducing offshore HPHT well completion times by 30 days or more
• Improving the definition and visualization of the reservoirs
• Eliminating the need for clean-ups, stimulation treatments or any other form of post-drilling well intervention to remove formation damage caused by the drilling fluid
This has all been made possible by the operators’ acceptance and adoption of the award-winning Chemical Leasing (ChL) and fluid management programmes that form the basis of their contracts with the sole producer of cesium formate brine. The use of the ChL model has played an important role in reducing the unnecessary consumption of what is a very rare and valuable chemical resource
SPE 165151 - The Long-term Production Performance of Deep HPHT Gas Condensat...John Downs
Formate brines have been in use since 1995 as non-damaging drill-in and completion fluids for deep HPHT gas condensate field developments. The number of HPHT fields developed using formate brines now totals more than 40, and includes some of the deepest, hottest and highly-pressured reservoirs in the North Sea. The well completions have been both open-hole and cased-hole.
An expectation from using formate brines as reservoir drill-in and completion fluids is that they will cause minimal damage to the reservoir and help wells to deliver their full productive potential over the life-time of the field. The validity of this expectation has been tested by examining the long-term hydrocarbon production profiles of eight HPHT gas condensate fields in the North Sea where only formate brines have been used as the well completion fluids. In five of these fields the wells were drilled with oil-based muds and completed by perforating in cased hole with high-density formate brines. In another two of the fields the wells were drilled with formate brines and completed with screens entirely in open hole using the same brines. The last of the eight fields was drilled with formate brine and the wells were then completed with same fluid in either open hole or cased hole.
The results of the production analysis provide a unique insight into the impact of a single type of specialist drill-in and completion fluid on the rate of recovery of hydrocarbon reserves from deeply-buried reservoirs in the North Sea
A Ramble through Cornwall - Day 8 - Bodmin to St Neot John Downs
A short (7 mile) walk from the outskirts of Bodmin east to St Neot, skirting the southern border of Bodmin Moor. Mostly walking in fog on this particular day
This document summarizes the key findings of a study on the effects of different well construction fluids on rig time savings. The study analyzed 89 North Sea wells and found that switching from oil-based muds to cesium or potassium formate fluids can save up to 26 days of rig time. Specifically, using formate fluids for open-hole standalone sand screen completions can save over 3.5 weeks compared to cased and perforated completions using oil-based muds. Formate fluids also significantly reduce completion times for both well construction techniques and increase drilling rates of penetration compared to oil-based muds.
DMK chose potassium formate brines over invert oil-based muds for drilling long horizontal wells in the abrasive Montney shales. They experienced significant cost and time savings from increased drilling rates of penetration (ROP), longer bit life, improved wellbore cleaning, and lower equivalent circulating densities (ECDs). Operators saw ROP improvements of 30-50% and bit runs twice as long as with oil-based muds. Using solids-free potassium formate brine allowed excellent horizontal wellbore cleaning without cuttings beds forming and reduced circulating pressures.
Cesium formate brine has been used as a completion and perforation fluid in 15 wells across 11 high-pressure, high-temperature (HPHT) gas fields in the UK sector of the North Sea since 1999. It was first used in Shell's Shearwater field and then Total's Elgin/Franklin field, the world's largest HPHT field. Since then it has been used in 12 additional HPHT wells in various fields. Production rates from wells completed with cesium formate brine have ranged from 1.6 to 2.6 million cubic meters per day. Some individual wells have achieved over 30,000 barrels of oil equivalent per day. Thirteen years after its first use, cesium
Open-hole sand-control completions using expandable sand screens (ESS) offer advantages over traditional cased-hole completions including improved production rates and lower installation costs. The documents discusses several case studies where formate brines and ESS were used together, setting world records for longest, hottest, and deepest ESS installations. This included projects by Shell in the Brigantine field in the UK North Sea and by Saudi Aramco in the K-field in Saudi Arabia, improving well economics in both cases.
This document summarizes Cabot Specialty Fluids' (CSF) sustainable business model of leasing cesium formate brines and retaining ownership of the chemicals. This model encourages efficiency by charging clients based on time used rather than consumption. It also aligns incentives between CSF and clients to minimize waste. The model has proven successful, with CSF normally recovering 80-85% of leased brines. The document notes UNIDO's support for innovative concepts like CSF's model that reduce chemical consumption and waste. CSF was honored with a UNIDO award for its contributions to advancing chemical leasing programs.
The document discusses eco-efficiency analysis conducted by BASF to compare the eco-efficiency of formate brines and bromide brines. The analysis found that formate brines were significantly more eco-efficient than bromide brines. Formate brines scored better on costs, lower toxicity potential, and lower emissions. In particular, bromide brines produced large amounts of toxic waste that required special treatment. While formate brines required more salt overall, they offered a more sustainable solution for the scenario of completing a well in the North Sea. BASF concluded that formate brines were the most eco-efficient option based on both environmental and economic factors.

Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.
LF Energy Webinar: Carbon Data Specifications: Mechanisms to Improve Data Acc...DanBrown980551
This LF Energy webinar took place June 20, 2024. It featured:
-Alex Thornton, LF Energy
-Hallie Cramer, Google
-Daniel Roesler, UtilityAPI
-Henry Richardson, WattTime
In response to the urgency and scale required to effectively address climate change, open source solutions offer significant potential for driving innovation and progress. Currently, there is a growing demand for standardization and interoperability in energy data and modeling. Open source standards and specifications within the energy sector can also alleviate challenges associated with data fragmentation, transparency, and accessibility. At the same time, it is crucial to consider privacy and security concerns throughout the development of open source platforms.
This webinar will delve into the motivations behind establishing LF Energy’s Carbon Data Specification Consortium. It will provide an overview of the draft specifications and the ongoing progress made by the respective working groups.
Three primary specifications will be discussed:
-Discovery and client registration, emphasizing transparent processes and secure and private access
-Customer data, centering around customer tariffs, bills, energy usage, and full consumption disclosure
-Power systems data, focusing on grid data, inclusive of transmission and distribution networks, generation, intergrid power flows, and market settlement data
Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

Getting the Most Out of ScyllaDB Monitoring: ShareChat's TipsScyllaDB
ScyllaDB monitoring provides a lot of useful information. But sometimes it’s not easy to find the root of the problem if something is wrong or even estimate the remaining capacity by the load on the cluster. This talk shares our team's practical tips on: 1) How to find the root of the problem by metrics if ScyllaDB is slow 2) How to interpret the load and plan capacity for the future 3) Compaction strategies and how to choose the right one 4) Important metrics which aren’t available in the default monitoring setup.
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?
