The purpose of the project was to support the characterization of the exploration targets, the optimization of the well trajectories and the de-risking of the drilling activities by providing the highest resolution depth imaging velocities and images of the subsurface, calibrated at the three available wells. The project was carried out by an integrated team of geophysicists, geologists and explorationists. The involvement of structural geologist is a regular procedure in such complex geological settings and was crucial for embedding salt tectonic concepts into the geophysical model. Furthermore, leveraging on the high computational capacity, several multiple salt scenarios were assessed, reducing the uncertainties in the most challenging areas: during the drilling of the first appraisal well, data were imaged with three different salt scenarios, exploiting all the available information coming from the live data from the well.","PeriodicalId":335882,"journal":{"name":"Second EAGE Workshop on Deepwater Exploration in Mexico: Knowledge transfer and collaboration from shelf to deepwater","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116452997","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}

This presentation will focus on the common wireline acquisition strategies that are used to evaluate Mexico turbidite formations where low resistivity pay and synthetic oil-based mud are used to drill the wells. A complete petrophysical evaluation integrates state of the art wireline technologies for true sand resistivity with lithology, porosity and permeability to better characterize the laminated vs dispersed clay distribution for an accurate reservoir summation. Combining the acoustic and borehole images for velocities (geomechanical applications) and using downhole in-situ stress testing techniques gives a more detailed understanding of depositional architecture and distribution of reservoir facies and flow units. Today, we use focused sampling techniques to better understand in-situ fluid characterization and achieve much cleaner and faster formation samples. The higher quality samples (low OBM contamination) are required for achieving the most accurate PVT, flow assurance, water compatibility, and crude analysis to optimize the “get it right the first time” large field development investments. In Mexico, Interval Pressure Transient Testing (IPTT), combined with downhole in-situ fluid analysis (DFA) are used to assess reservoir characteristics layer by layer. This applied work flow methodology is an important input for the Reservoir Fluid Geodynamic (RFG) study to resolve and minimize the uncertainties of the reservoir architecture and de-risk future developments. Other technologies deployed during the Wireline acquisition program include a Mechanical Sidewall coring program and the VSI (Vertical Seismic Imager). The Mechanical Sidewall coring tool is used to for depth correlated extraction of core samples in reservoir and non-reservoir rocks formations. This tool has successfully acquired sidewall cores in low UCS rock strength and samples are used for rock and permeability analysis. This service complements the full conventional core program by allowing additional samples to be taken where whole core is not required. Finally, in areas where there is uncertainty in the surface seismic, the VSI (Vertical Seismic Imager) is used to acquire a borehole seismic with Zero Offset or Walkaway surveys. The borehole surveys provide accurate determination of formation tops and are used for further calibrating the reservoir model versus the surface seismic. Turbidite and low resistivity formations are much better understood with the application of industry proven technologies. This presentation will discuss the Mexico workflow and methodology and application of these measurements to maximize the understanding of these special reservoirs located in t","PeriodicalId":335882,"journal":{"name":"Second EAGE Workshop on Deepwater Exploration in Mexico: Knowledge transfer and collaboration from shelf to deepwater","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122296332","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}

Winter","doi":"10.3997/2214-4609.201900358","DOIUrl":"https://doi.org/10.3997/2214-4609.201900358","url":null,"abstract":"Summary The Sureste basin is characterized by multiple phases of deformation which are linked to distinct tectonic events. The structural history includes: (1) rifting of the Gulf of Mexico, (2) Chiapaneca contraction associated with subduction of Cocos plate, and (3) Neogene gravity sliding. Based on integrated 2D and 3D seismic mapping in the eastern offshore Sureste basin, we were able to identify and interpret a linkage between the base-salt faults and the subsequent deformation structures. Deposition of the autochthonous salt layer filled a Jurassic rift basin. The original salt thickness in the eastern part of the Sureste basin controlled the structural style during extension and resulted in the formation of reactive triangular salt rollers; the rollers occur in the footwall of the main extensional faults. Mesozoic supra-salt extension occurred from the Oxfordian to the middle-late Cretaceous. The eastern edge of the Sureste Salt basin thins towards a basement feature interpreted to be a basement horst located on the east side of a rift related transfer fault zone. Tear faults approximately developed in the same location in the surpra-salt strata during later Mesozoic post-salt extension. These tear faults appear to have influenced the stratigraphic filling of supra-salt extensional basins. The tear faults were reactivated due to (1) NW-directed Chiapaneca contraction, and (2) right-lateral strike-slip movement during SW-directed Catemaco gravity sliding. Extensional tear faults in the eastern Sureste basin correspond with the eastern limit of Middle Miocene Chiapaneca thin-skin contraction. NW-SE oriented anticlines and thrusts lie to the west of the tear faults. The area to the east lacks pronounced thin-skin Chiapaneca folds. Onshore uplift caused by subduction of the Cocos plate led to tilting of the margin and the development of a large-scale NW-directed gravity slide in the shallow water. Strike-slip displacement along the eastern limit of the gravity slide reactivated the Mesozoic tear faults. The tear fault represents the eastern the limit of well-known extensional gaps such as the Comacalco and Macuspana basins in Sureste basin. Understanding the sequence, relationship and intensity of deformational events are key in revealing the basin structural evolution and offer insights to the exploration efforts in the Mexican offshore basins.","PeriodicalId":335882,"journal":{"name":"Second EAGE Workshop on Deepwater Exploration in Mexico: Knowledge transfer and collaboration from shelf to deepwater","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133337003","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}
