It consists of injecting steam to decrease the oil viscosity in the reservoir. During this process, the steam reacts with the oil due to the high temperature leading to the emission of the corrosive and highly toxic H2S if the oil contains sulfur. These reactions are called aquathermolysis. Understanding the mechanisms leading to H2S generation in the reservoir and to its resulting production at surface is of paramout importance for field operators in order to properly design their surface facilities and respect the environmental regulations. This study aims at providing more insights into these mechanisms. In particular the H2S generation and its distribution among the gas, oil and water phases in the reservoir have been investigated as well as its production process at well. Sensitivity analyses of H2S emissions on the injection temperature and the reservoir permeability have also been investigated. Overall this work illustrates the complex interactions between chemical reactions, thermodynamics equilibria and multiphase flows occuring in the reservoir and gives further insights on the mechanisms leading to the H2S production and its variation at the wellhead during the lifetime of a SAGD project.","PeriodicalId":438697,"journal":{"name":"First EAGE/IFPEN Conference on Sulfur Risk Management in Exploration and Production","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127841253","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}

These processes are associated with chemical reactions occurring in the reservoirs, called aquathermolysis, which produce carbon dioxide (CO2) and H2S. Hence it needs to be given a particular attention when it is produced at the surface. To manage the risk of H2S production in thermal projects, the reservoir simulation including aquathermolysis reactions is a valuable asset. In this paper, we present a workflow combining experimental aquathermolysis with sulfur balance and reservoir numerical modeling. This workflow allows forecasting H2S production and oil composition in thermal projects. This paper focuses on presenting the three stages of the workflow . The first stage consists in a rapid localization of the reservoir areas that are prone to generate H2S, based on sulfur screening with the Rock-Eval Sulfur. The second stage consists in aquathermolyse experiments aiming at reproducing the chemical reactions that occur in the reservoir, and quantifying H2S yield as a function of time, temperature and reservoir properties. The third stage consists in reservoir simulation using an aquathermolysis kinetic model calibrated with the experimental data obtained on stage 2.","PeriodicalId":438697,"journal":{"name":"First EAGE/IFPEN Conference on Sulfur Risk Management in Exploration and Production","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131495705","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}

Certain minerals e.g. siderite (FeCO3), iron oxides (FexOy), and iron-bearing clays may react with produced H2S and retard its progress towards the producer wells. Despite the impact that these parameters may have on the development of reservoir souring models, there are no published experimental studies that have sought to explain the mechanisms of H2S scavenging or to quantify scavenging capacities for commonly occurring iron minerals. Focussing primarily on siderite but with additional data from field core samples, a combination of static bottle tests and dynamic sand pack experiments were used to identify and quantify H2S scavenging. This study has observed two proposed mechanisms for H2S reservoir scavenging, namely dissolution/precipitation, which depends on the stability of the Fe-bearing minerals, and surface displacement, which depends on the relative solubilities of the resultant precipitates. These mechanisms were rationalised using a suite of analytical techniques; ICP-OES, ESEM-EDX, pH data and particle size analysis. Capacities in the order of 0.5 to 13 mg/g (mg H2S per gram of active substrate) were calculated over a range of initial pH values and temperatures.","PeriodicalId":438697,"journal":{"name":"First EAGE/IFPEN Conference on Sulfur Risk Management in Exploration and Production","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132929932","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}

These samples have variable bulk and molecular compositions reflecting differing redox conditions, inputs of iron, and organic matter quantity/quality (TOC up to 18wt%, Type I-II/III kerogen). Reactive iron (FeR) availability is a controlling factor on the sequestration of sulphur into inorganic and organic fractions (Raiswell et al., 1993). Organic matter sulphurisation has economic implications but can also bias the interpretation of organic biomarkers (Kohnen et al., 1991). It has been suggested that sulphide buffering by FeR strongly influences biomarker preservation in bitumen (Reinhardt et al., 2018, on isorenieratene). The effect of individual FeR fractions sulphurisation is investigated. In particular, magnetite does not appear to act as FeR in many samples. This could potentially be a function of the terrigenous input (e.g. magnetite grain size), or caused by its lower reactivity affecting its pyritisation behaviour in less persistently reducing environments. Examining the behaviour of FeR fractions under different conditions and their effects on organic matter sulphurisation is essential to improving our understanding of FeR and biomarker proxies and their biases.","PeriodicalId":438697,"journal":{"name":"First EAGE/IFPEN Conference on Sulfur Risk Management in Exploration and Production","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130829465","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}

In addition to serious health and safety concerns, this can cause significant production problems such as reduced quality of sales gas and crude, degraded productivity of wells, increased corrosion or enhanced scaling. Therefore, the realistic assessment of the magnitude of biogenic souring is of highest importance when it comes to project development to be able to mitigate and inhibit. However, physical and numerical estimation of the souring related parameters is highly unsatisfying in most of the cases due to significant uncertainties when making a deterministic assessment. The objective of the paper is to assess biogenic souring based on two different techniques using a commercial reservoir simulator as tool. Previous studies as well as the outcome of on-going field projects are used to develop the assessment concept and required input parameters. The results are provided as uncertainty analysis with their potential implications on field applications.","PeriodicalId":438697,"journal":{"name":"First EAGE/IFPEN Conference on Sulfur Risk Management in Exploration and Production","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125596785","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}
