One of the example of such implementation is Achimov layer, which is shaly-sand deposits of deepwater genesis, associated with the fondoform part of clino-cycle on the Neocomian age. Difficult geology aspects, high degree on unexploration contributes to the presence of various problems in the development of these sediments. Some problems also has historical background: in the past Achimov deposits were the transition interval for more deep-located Jurassic deposits which leads to low representativity of core data and narrow complex of logging tools.\u0000 Achimov sediments represented by complex anisotropic reservoirs and usually have thin laminations of siltstones and sandstones. Vertical resolution of these laminations could vary from the first centimeters to the first dozen centimeters. Identification of perspective intervals and reliable estimation of their formation properties by the logging is assosiated with a number of difficulties, main of which is insufficient vertical resolution of tools.

The first challenge is the near wellbore damage due to the invasion of the completion fluid to the formation. The second challenge is the additional operating cost associated with both rig time spent to pump fluid into the well and stimulation treatment to restore the initial formation condition. The third challenge is maintaining a safe window of overbalance condition during the workover operation which is a major HSE & well integrity concern.\u0000 The outmoded technique to control losses is to use solids base fluid which could damage the formation if not properly removed after the treatment. Also, in some cases it requires an acid breaker to restore the original formation state. The acid treatment must be done before installing the pump in hole as the solid-fluid system can't be flow back through the artificial lift.\u0000 KOC keeps the safety window of the overbalance by pumping completion fluid (brine) into the well while killing operation. As a consequence, rig had to pump hundreds of bbls of brine into most of the depleted reservoirs which in most of the cases causes sever wellbore/reservoir damage (major concern) leading to delay in Production and increase in operation cost associated with rig time and completion fluid cost.\u0000 Customised Salt Pill system is a unique solution for such challenge, and it had been proved trouble-free globally by sealing the face of the formation during the killing operation. Recently the salt pill system was deisgned and deployed in a well in one of KOC brown fields, the job magnificently compiled with KOC success criteria safely. Moreover, the fluid level was static in the well during the entire workover operation. With the successful flow back for the well after ESP installation, demonstrated no wellbore damage with salt pill even without requiring any breaker nor acid.\u0000 The application of Salt Pill was successful and it lead to saving of approximately two days of rig time and Early Production from the well without damaging the reservoir with the invasion of completion fluid. This innovative solution has opened the way forward for KOC to implement same technology in other sub-hydrostatic wells.","PeriodicalId":242965,"journal":{"name":"Day 2 Tue, October 16, 2018","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130369247","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 research of fissuring and its further deformation mechanism is necessary both for drilling risk assessment (prediction of fluid losses zones due to intensive natural fracturing) and for ranging of perspective drilling zone in terms of its productivity.\u0000 For described reservoir it is supposed, that natural fractures are the main driver of wells productivity. Reservoir rock is characterized by low average matrix porosity (lower than 3%), which does not influence wells productivity.\u0000 As for fractures system, according to production logging (spectral noise survey), wide-bend acoustic logging (Stoneley wave interpretation), formation imager (resistivity and acoustic), drilling data (fluid losses) it was concluded that not all fractures are permeable. Comparison of fracture characteristics from different surveys shows that working intervals according to SNL mismatch with permeable intervals from Stoneley wave interpretation and do not fit with maximum fracture density intervals from formation imager.\u0000 The analysis showed mismatching of productive intervals from Stoneley wave interpretation and SNL results and absence of direct correlation between fracturing and productive intervals for both methods. This can be explained by low amount of working fractures: less than the half of horizontal section works. Moreover, the risk of drilling throught \"dry\" zone, where no permeable fractures exist, was confirmed by several unsuccessfull wells.\u0000 On the base of geological and morphological fracture features such as intensity, dip angle, orientation there is no ability to subdivide dry and permeable fractures. That is why for better reservoir understanding the mechanism of fracture occurance, development and activation is analysed.\u0000 Application of geomechanical modeling for fractures assessment and subsequent forecast of productive zones is rather nontrivial and complex task that required abandoning the traditional approach of creating a geomechanical model in which the main emphasis is on a wellbore stability calculation.","PeriodicalId":242965,"journal":{"name":"Day 2 Tue, October 16, 2018","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114365745","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 assessment was performed using a coupled reservoir geomechanics modeling that allowed to estimate the changes in in-situ stresses state with field development.
