Similarly, some infill drilling operations are conducted with the scope of avoiding interception with other wells. A prototype of a tool for Active Magnetic Ranging While Drilling (AMR) without the use of a wireline operation has been developed. The main scope of the current article is presenting the results of a prototype test of this new tool in attest well.\u0000 The ranging tool emits a low frequency alternating current into the formation to reach the target well, and then run through that's casing back to the well being drilled. This electric current set up a variable magnetic field that is measured by the AMR tool determining the direction towards the target well as well as the distance. If drilling a relief well, 10 - 25 wireline runs are needed before the target well is intercepted. The present AMR tool is fully integrated in the drill pipe and, thus, all the tripping operations are avoided.\u0000 A prototype of an active magnetic ranging tool on the drill pipe has been developed. This tool is outlined in detail in the paper. Most focus will be given to a performance test conducted in a research well in Norway. A drill pipe is placed in a vertical well, being the target well. The AMR tool was run in the research well and the direction and distance to nearby target wells was measured. The set-up and the results of this logging operation conducted on a drill pipe is described in detail. It is shown how the direction and distance between the two wells are measured using the tool.\u0000 Most intercept operations are not relief well drilling, but cases where a well needs to be intercepted because a well section shall be connected to another well, or during plug and abandonment operation. The tool can also be used for avoiding collision with other wells, which is a relevant scope for drilling infill wells in older fields or radiator wells in geothermal drilling. The tool and its potential are outlined in the paper.","PeriodicalId":213852,"journal":{"name":"Day 2 Wed, September 06, 2023","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121050550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Syslak","doi":"10.2118/215530-ms","DOIUrl":"https://doi.org/10.2118/215530-ms","url":null,"abstract":"\u0000 Acoustic Sand Detectors (ASDs) have been widely used on topsides and subsea flowlines to measure sand production for the last 25 years. Essentially, ASDs are filtered microphones, strapped onto a bend or tee, that detect ultrasonic noise generated by impacting sand.\u0000 ASDs are typically used either to detect the presence of sand or to quantify the sand rate. In the former case the well will typically be choked back when sand is present. This approach has the disadvantage that production may be curtailed even when sand production is too low to be problematic. Alternatively, the ASD could be calibrated by means of a sand injection. Once calibrated the ASD can output the sand rate in grams per second, allowing the operator to judge whether the sand rate justifies choking back the well. This strategy can significantly boost production rates. However, sand injection is not always feasible for topsides ASD installations and has never been done subsea (to our knowledge).\u0000 This paper summarises work that attempts to address this limitation. A correlation was developed that calculates ASD calibration coefficients without the requirement to perform a sand injection. It works on the assumption that sand noise increases when fluid noise increases, with additional corrections for various multiphase flow effects. The correlation was developed using historical data from laboratory tests and from offshore sand injections. It was then validated against additional historical topsides injection data from platforms in the North Sea. In this initial assessment the correlation was validated against approximately 800 data points.\u0000 One of the main potential applications of the correlation is to help estimate sand rates using data from subsea ASDs. Unfortunately, no suitable subsea data was available that could confirm the validity of the correlation, but it was shown that ASDs respond differently when installed subsea. Subsequently, laboratory flow loop testing was performed with ASDs installed on a pipe submerged in a pool. This confirmed that the correlation has a similar accuracy for both topsides and subsea ASD installations. The correlation is currently being trialed by an operator with a view to using it as a tool within their overall sand management strategy.\u0000 ASDs are widely installed, but their output is often poorly understood or misused. This paper outlines the correlation methodology and identifies the possibilities and limitations of other approaches. The validation and testing exercises also flag a range of other issues when using ASDs; the effects of poor installation; how subsea acoustic attenuation affects ASDs; and important considerations when performing sand injection calibrations.","PeriodicalId":213852,"journal":{"name":"Day 2 Wed, September 06, 2023","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129058698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Widyanita","doi":"10.2118/215579-ms","DOIUrl":"https://doi.org/10.2118/215579-ms","url":null,"abstract":"\u0000 A depleted gas reservoir in Central Luconia field, located offshore Sarawak, was evaluated for future carbon dioxide (CO2) storage. This carbonate reservoir has experienced seafloor subsidence during producing life. When coupled dynamic-geomechanics model was history matched, it was discovered that earlier understanding of reservoir performance along with aquifer extent and size were incomplete. This new understanding has led to a significant change in forecasted CO2 storage capacity of the reservoir.\u0000 In this reservoir, as production rate declined, reservoir pressure decline started reversing. During the producing life of the reservoir, standalone history matched dynamic model was used to forecast reservoir performance. This model sufficiently explained production performance and in fact production forecasts made from the model were reliable. After the reservoir had ceased to produce, it was evaluated for CO2 storage. As part of the CO2 storage studies, a coupled dynamic-geomechanics model was built. This was when it was noted that seafloor continued to subside even as reservoir pressure was increasing post cessation of production. This highlighted the fact that something other than hydrocarbon reservoir section was compacting. Further studies revealed that regional aquifer that was not included in the standalone dynamic model was undergoing compaction post-production.\u0000 This reservoir has a bottom acting aquifer, which has a barrier/baffle zone at the bottom of the aquifer that separates it from an extended/regional aquifer. Standalone dynamic model was truncated at the barrier/baffle zone. This aquifer was sufficient to explain the pressure support received but was insufficient to explain sea floor subsidence post-production. Further studies revealed that the hydrocarbon section was in communication with extended aquifer. And the baffle zone has a major role to play in understanding CO2 storage. Using dynamic-geomechanics coupled model with extended aquifer, it was discovered that baffle zone undergoes pore collapse during production. This translates to significantly lower aquifer efflux across the baffle zone during CO2 injection compared to aquifer influx during production. This directly impacts the storage capacity of the reservoir since the invaded aquifer could not be efficiently displaced by injected CO2. Storage capacity estimate from coupled dynamic-geomechanics model is about 50% lower compared to standalone dynamic model.","PeriodicalId":213852,"journal":{"name":"Day 2 Wed, September 06, 2023","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126403918","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Qasim, Ali Yousef","doi":"10.2118/215556-ms","DOIUrl":"https://doi.org/10.2118/215556-ms","url":null,"abstract":"\u0000 The geological carbon storage (GCS) in subsurface environments, such as deep permeable saline formations, is one of the achievable methods for carbon dioxide storage. There are several commercial projects such as the Sleipner field in Norway, and in Salah in Algeria have demonstrated that carbon dioxide can be safely stored in these reservoirs. The natural environments are capable to store CO2 on geologic time scales, that is mostly caused by solubility trapping. While the geological, physical and chemical conditions for the escape of CO2 are still in the research phase and how CO2 can be efficiently stored, there are several important features that represent prerequisites for the efficient storage (Xu, et al. 2017).\u0000 A core prerequisite is the availability of sufficient porosity in order to accommodate the desired volumes of carbon dioxide, and the presence of a continuous cap rock that is impermeable to CO2. Deep saline reservoirs are attractive candidates for the geological storage and based on the deep geologic storage temperature and pressure, the CO2 is typically in a supercritical but stable state. The challenge is that the introduction of CO2 into the reservoir may lead to a geochemical process which acidifies the brine via CO2 dissolution. Furthermore, the mineral surfaces are dehydrated by the dispersing CO2 phase. Experimental and field studies indicate that the geochemical reactions caused by the injection of CO2 may vary significantly between different rock types and brine compositions (Michael, et al. 2010). The low permeability of the cap rock, such as shale, have demonstrated to be reactive for higher temperature ranges, which poses additional challenges for the CO2 storage process. The dissolution and re-precipitation of carbonate minerals, and the dissolution of feldspars are generally observed for these CO2 storage reservoir sites that additionally encounter challenges related to the precipitation of clay minerals. This implies that the dissolution and secondary mineral precipitation caused by the injection of CO2 have a major impact on the porosity and permeability of the reservoir environment as well as impact the cap rock integrity (Jiang, et al. 2014).","PeriodicalId":213852,"journal":{"name":"Day 2 Wed, September 06, 2023","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124488001","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The realism of the scenario creates a memorable experience and helps users remember key safety messages from the VR and the training programme they are embedded in. The immersive learning environment, which is engaging and fun, has proved to be a highly effective method of learning. Direct learning points include hazards and SECEs that are specific to each scenario, risk assessments and incorporation of the IOGP process safety fundamentals and lifesaving rules, but the discussions that can be had around the VR have proven to be equally valuable.\u0000 Like the majority of the 10 operators currently using the MAH VR, Harbour Energy have tailored their MAH awareness training around the virtual reality, which has played a critical role in engaging the workforce and facilitating training around the consequences if mistakes are made. The result of the VR technique and planned deployment by Harbour has been further improvement in MAH engagement across the whole company. In a clear demonstration of this success, Harbour Energy have recently won the IChemE Training and Development Award in 2022 for Fostering Process Safety Culture Through Innovation, for their VR programme.\u0000 The use of VR is a novel method for MAH awareness training, which gives the industry a new approach to this.

The spiral wound element was developed in 1970 to package RO and NF material into compact, efficient, and usable unit. Over the last decades, optimization of the manufacturing processes such as robotic glue lines and automated rolling of the elements, provided incremental improvements in the ability to pack more active membrane area in the same limited available volume defined by the length and diameter of the 8\" element; but as the technology became mature, the room for further packing improvements vanished and spiral element configuration has reached an optimal plateau. Available membranes in the market have mainly been optimized up to two standard offerings: a) the higher surface of 440 ft2 per element using thinner feed spacer of 26-mil, or b) the thicker feed spacer of 34-mil having 400 ft2 per element. System designers decide on either of the optimizations depending on the feedwater and pretreatment quality, being the high surface of 440 ft2 elements reserved for \"good\" feedwaters. This optimal plateau drove the market at least over the last decade where all new models launched offer improvements in either rejection, permeability, fouling resistant or robustness. However, all these new products have not varied in packing density that remained unchanged.\u0000 Thanks to innovation in materials science, a new generation of RO and NF elements has been developed using unique New Thin-membrane technology. This unique technology allows for significative improvement in the packing density, offering the possibility of taking advantage of the combination of both forementioned optimizations in the same membrane element, that is the high active surface area of 440 ft2 and the 34-mil feed spacer. Alternatively, the technology allows to keep the thinner 26-mil feed spacer but boosting the active membrane area up to 510 ft2 per membrane element.
