Abstract:

Endowment life insurance is a type of life insurance that involves two types of benefits, namely the company will provide compensation if the insured remains alive at the end of the policy term or dies during the policy term. Premium reserves are the amount of funds that must be available to the insurance company as funds for preparing claim payments to the insured. The aim of this research is to calculate the annual premium reserve value in one of the assumed cases of Company XYZ with a coverage period of 35 years and a premium payment period of 20 years. Calculation of premium reserves can b

Abstract:

Life insurance is one of protections in society by providing economic protection for insurance users who experience an adverse event. The insured who is an insurance user has an obligation to pay the premium at the time that is determined by the insurance company and the policyholder. Insurance companies need funds to fulfill claims from policyholders, so premiums that have been paid are stored in the form of premium reserves. Premium reserves need to be managed by the company properly so that the company does not experience losses. The purpose of this research is to provide information to det

A material balance equation (MBE) is usually employed to estimate well-controlled dynamic reserves, but a more accurate calculation of these reserves is crucial. For abnormally pressured reservoirs with aquifers, the abnormally pressure and aquifer are difficult to determine, which leads to inaccurate calculations of well-controlled dynamic reserves. In this work, the MBE was established. Then, the correction function and abnormally pressure effect were deduced to determine well-controlled dynamic reserves calculations for weak aquifers and strong aquifers, respectively.

Abstract:

A claims reserve is money set aside for a claim that has been Reported But Not Settled (RBNS) or Incurred But Not Reported (IBNR). Claim reserves are crucial for the financial stability of insurance companies. Operationally, we can know the amount RBNS, but we don’t know the amount of IBNR. Therefore, actuarial literature has proposed numerous IBNR calculation methods, which are usually based on statistical concepts. However, the mutant and uncertain behavior of insurance environments for each insurance company does not make advisable to use a wide database across all insurance companies in Ca

Based on review of previous information and correlation of 7 lithostratigraphic sections from well data, it was possible to establish the presence of channels in fluvial environments of the Mugrosa Formation, with good lateral continuity, in the B and C zones, in the Middle Magdalena Valley Basin (VMM). The results of well log interpretation (NSP logs) indicate the presence of channel sands and proved the previous sedimentological model of the field. In the sedimentological model proposed, zones B and C (Mugrosa Formation) show a very good lateral continuity of sands. The reserve calculations

Abstract:

The calculation of premiums and reserves are two essential parts of insurance. The calculation of premiums and reserves in life insurance involves using mortality tables. This research constructed a mortality table for 20-year endowment insurance using the Markov chain model. Two reasons make the policy inactive, namely death or withdrawal. The initial age used in this research is 30 years. Meanwhile, the maximum age to join this life insurance is 40 years. The mortality table that has been obtained is used to calculate premiums and reserves. Furthermore, from the research done, it was found t

Abstract:

Accurately calculating dynamic reserves for single well in a low-permeability gas reservoir has an important guiding significance to high efficiency development of the gas reservoir. During the development of the gas reservoir, dynamic analysis methods were often used to calculate dynamic reserves. Dynamic analysis methods mainly include the material balance method, the gas production method in unit pressure drop, the flexible two-phase method and the production unstable method. Dynamic reserves for four types of gas wells in a low-permeability gas field were calculated using these four method

This paper proposes a method for determining the boundary values of open porosity (KPO_GR) and gas permeability (KPR_GR) of porous-type carbonate reservoir rocks using the example of Tournaisian deposits of one of the oil fields of the Republic of Tatarstan. When justifying the boundary values, two databases on core studies are used: 1) on standard core studies (used mainly to calculate hydrocarbon (HC) reserves); 2) on special core studies (used for technological development projects). In the proposed method, the residual oil saturation factor is not a constant, but is taken from flow studies
