These are the result of uncertainty in the measurements, the low permeability of the reservoir, and changes caused by industry activity. Slow pressure changes during production tests or diagnostic fracture injection tests (DFITs) require significant extrapolation to obtain the reservoir pressure. A third source of data comes from the mud weight required to control a kick. Unconventional reservoirs are often drilled underbalanced and if the kick is the result of encountering a natural fracture, the mud weight required may be lower than the reservoir pressure due to the limited hydrocarbon volume of the fracture. The uncertainty in the measurements result in a wide range of pressures that can make it difficult to identify important outliers caused by geological differences or by industry activity in the area. Kicks close to lithostatic pressure can be encountered when drilling into a hydraulic fracture of a nearby well. This can have major safety and financial implications. Regulations have been put in place requiring operators to identify offset wells that could be affected by hydraulic fracturing operations and work together with their competitors to stay safe.","PeriodicalId":295902,"journal":{"name":"Second EAGE Workshop on Pore Pressure Prediction","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123803426","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}

To meet such a challenge Managed Pressure Drilling is increasingly being used to manage narrow pore pressure windows and drill deeper, higher pressure and higher temperature wells than was previously possible. At the same time the industry is facing stronger environmental and safety regulations that demand an improvement in risk characterization and pore pressure detection. While the new data from such techniques is valuable in constraining the pore pressure, it comes in new formats and often replaces or excludes some of traditional data such as connection gas that are normally used in real time pore pressure detection. Two cases are presented from two oil & gas exploratory wells in which the application of MPD (Managed pressure drilling) technique was critical for the success of the operation and where valuable pore pressure information was obtained to characterize and manage the drilling window. We conclude that MPD is an important tool in drilling wells with a narrow pore pressure and fracture gradient window. While MPD complicates some of the traditional methods of pore pressure estimation, it can be used proactively to get more accurate estimates.","PeriodicalId":295902,"journal":{"name":"Second EAGE Workshop on Pore Pressure Prediction","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122867157","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 Total E&P, the method of calculating stress around the wellbore in order to predict the FG has been used and developed for a decade. It primarily consists of building and calibrating a ID MEM, using proprietary ID poro-mechanical earth model named PoroMEM. The calculation of the FG from the in situ stress model uses two conceptual models of fracturing: shear fracture and tensile fracture. From there, we define two limits for FG: one called FIPmax and the other FIPmin. Such conceptual models help to deal with the uncertainties of rock mechanical behavior because of vertical variability of lithology, help the preparation LOT/FIT during drilling operation, and also aid the interpretation of LOT/FIT. The in situ stress model from PoroMEM also provides the FCP gradient which is useful for well control and is sometimes as the FG. In this paper, we present the conceptual models and an example of FG prediction.","PeriodicalId":295902,"journal":{"name":"Second EAGE Workshop on Pore Pressure Prediction","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114607586","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}
