Several mathematical models have been developed for estimating water influx in petroleum industry, but the current paper will address the application of Fetkovich aquifer model to predict the gas reservoir performance considering the pressure changes that gradually occur within the aquifer and between the aquifer and reservoir. The applicability of this model has proven to be extremely useful in estimation of initial gas resources, aquifer volume and its parameters, confirming the producing mechanism but also forecasting the production performance of the gas reservoir. The authors will highlight through some case studies, the importance of the water influx analysis and prediction, in particular for natural gas reservoirs, which subsequently allows for adequate planning in optimizing the reserves’ recovery.","PeriodicalId":123572,"journal":{"name":"AGH Drilling, Oil, Gas","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129671309","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}

Placing a jet pump above the dynamic level in the well and operating it simultaneously with the sucker rod pumps allows to stabilize the work of the rod pump, avoid fluctuations of the dynamic level and facilitate the rise of the production liquid to the surface due to the reduction of the density of the mixed flow after the jet pump. In order to implement such oil-gas jet pump in oil wells that are operated by sucker rod pumps, it is necessary to determine their operating modes and choose the most effective among them. A methodology for calculating the operation mode of such well was created that allows determining the efficient location of jet pumps in oil wells and their geometry. When developing this methodology two conditions were taken as a main aim: the whole amount of free gas, which enters the casing annulus of the well, must pass through the oil-gas jet pump and to reach the maximum possible decreasing of the string load. For the 753-D oil well in Dolyna Oil Field calculated efficient operation mode shows the possibility to decrease string load by 26 , reduce electricity consumption and, respectively, investments in oil extraction.","PeriodicalId":123572,"journal":{"name":"AGH Drilling, Oil, Gas","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125227953","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}

Revitalizing these fields extends their productive lives and offers significant opportunity to expand worldwide reserves. Regardless of the definition, mature fields are a huge resource. With reserves categorized as proved or probable, attempts to expand reserve levels come at a relatively low risk. Revitalizing a mature field means taking measures that increase the value extracted from the field beyond original expectation. Using specialized software brings new opportunities in reservoir simulation of mature gas reservoirs. Combining these simulations with high resolution geophysical investigations, will offer a other perspective about mature gas reservoirs as well as the identification of potentially gas bearing layers which in the first place were not been identified through logging, and in addition to a eventual growth of gas resources but also gas reserves that could be exploited. Identifying the thinest gas saturated layers, determine the modification of gas resources and reserves values. The increase of volumes is a result of larger production surfaces, larger net thicknesses and also larger porosity attributed to this zones. For mature gas reservoirs this kind of approach offers new perspectives.","PeriodicalId":123572,"journal":{"name":"AGH Drilling, Oil, Gas","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129009442","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}

{"title":"Ways of increasing natural gas storage capacity in underground gas storages in the Czech Republic","authors":"P. Bujok, M. Klempa, Antonín Kunz, M. Porzer, R. Rado, Erik Roček, Jakub Ryba","doi":"10.7494/drill.2019.36.1.113","DOIUrl":"https://doi.org/10.7494/drill.2019.36.1.113","url":null,"abstract":"Natural gas fields are usually located far away from the end users and industrially developed countries, where the gas demand is highest. In such cases, natural gas is transported from the production site to the receiver mainly with gas pipelines. Such pipelines may transmit a definite volume of natural gas. Most of the time gas transport is stable in time, unless the demand changes, e.g. in winter or in the case of pipeline failure. In such a case the pipeline system cannot cover the increased demand and supply sufficient amounts of gas. One of the ways to solve the problem of varying demand and limited potential as far as gas transmission over long distances is concerned, are underground gas storages, thanks to which the operational gas deliveries can be regulated, i.e. it can be stored in periods of lower demand and used in the high demand situations. This safety buffer provides the stability and reliability of the entire natural gas distribution system. The methods of increasing the natural gas storage capacity of UGS were discussed in this paper with special emphasis on the primary and secondary tightness of geological structures hosting UGS. Authors also analyzed how laboratory tests conducted at VŠB-TU Ostrava can be broadened to verify the possibilities of increasing natural gas storing capacity, depending of the geological horizons and structures in which the UGS is located.","PeriodicalId":123572,"journal":{"name":"AGH Drilling, Oil, Gas","volume":"129 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129389586","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 is particularly true in horizontal wells, where the pay zone can be exposed to the drilling fluid over a long interval. Selecting the most suitable fluid system for drilling into the pay zone requires an understanding of the reservoir. Using data generated by lab testing on core plugs from carefully selected pay zone cores, a reservoir-fluid-sensitivity study should be conducted to determine the morphological and mineralogical composition of the reservoir rock. Natural reservoir fluids should be analyzed to establish their chemical makeup. The degree of damage that could be caused by anticipated problems can be modeled, as the effectiveness of possible solutions for mitigating the risks. In addition to being safe and economical for the application, a Reservoir Drill-In Fluid should be compatible with the reservoir's native fluids to avoid causing precipitation of salts or emulsions production. A suitable nondamaging fluid should establish a filter cake on the face of the formation and shouldn't penetrate too far into the formation pore pattern. The fluid filtrate should inhibit or prevent swelling of reactive clay particles within the pore throats. Formation damage commonly is caused by: – Pay zone invasion and plugging by fine particles. – Formation clay swelling. – Commingling of incompatible fluids. – Movement of dislodged formation pore-filling particles. – Changes in reservoir-rock wettability. – Formation of emulsions or water blocks. Once a damage mechanism has diminished the permeability of a reservoir, it seldom is possible to restore the reservoir to its original condition.","PeriodicalId":123572,"journal":{"name":"AGH Drilling, Oil, Gas","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126522931","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}

Organic rich shales are anisotropic due to their laminated structure and chemical properties. The goal of this study is to evaluate anisotropic mechanical properties of shale by triaxial tests, and predict shale anisotropic properties by well logging data interpretation. Shale samples were prepared with bedding plane inclination angles equal to 0 degrees, 45 degrees, and 90 degrees. Young's modulus, shear modulus, and Poisson’s ratio in different directions were measured for a sample with 0 degrees bedding plane inclination angle. Parameters of the stiffness tensor were calculated by mechanical properties. Compressive strength was measured under different confining pressures of 0 psi, 500 psi, 1000 psi, and 1500 psi. The strength properties of shale samples were evaluated by both compressive strength and tensile strength. Simple Plane of Weakness and Modified Cam Clay failure criteria were applied to describe shear failure mechanisms. A scanning electron microscope method was used for the comparison of micro structures between the intact shale sample and failed sample with different bedding plane inclination angles. Well logging data was used to connect experimental lab data and field data. Compressional wave velocity was predicted with different inclination angles by stiffness parameters. The predicted compressional wave velocity for a 45-degree inclination angle showed a perfect fit with the field logging data. Steps of inverse sonic log data to stiffness parameters were shown by a flow chart. The UCS strength for 0 degrees and 45 degrees was predicted by several empirical relations using sonic logging data. The safe mud window for this special shale formation is predicted by experimental data. As shown in experimental results, our shale sample has a weak direction for both failure criteria. Well logging data and experimental data can be connected, especially by sonic log data. However, to predict shale anisotropic strength through well logging still requires more effort. The novelty of the process which connects experimental results and well logging data will be helpful for solving instability problems occurring in shale formation.","PeriodicalId":123572,"journal":{"name":"AGH Drilling, Oil, Gas","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131027030","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}
