Abstract:
The process of developing oil and gas fields requires continuous monitoring of the current oil and gas saturation of productive reservoirs. Monitoring the current oil and gas saturation allows for effective hydrocarbon recovery. Solving this problem under the conditions of a cased hole significantly limits the suite of geophysical methods, which are the main source of information about the conditional characteristics of reservoirs. The most effective geophysical methods for determining the current oil and gas saturation of a productive reservoir in a producing well is deemed to be the methods

Abstract For logging pulsed neutron tube with diameter less than 25 mm, a smaller diameter Penning ion source with a cylindrical plasma volume of Φ8 mm × 9 mm was designed to investigate the pulse characteristics of anode current. The pulse time and amplitude characteristics of anode current as a function of deuterium pressure and anode voltage were studied experimentally. The preferred working parameters for this smaller diameter Penning ion source were suggested, then obtained the pulse amplitude of anode current in the range of 1 mA∼ 3.5 mA, with the shortest pulse delay time of anode curre

Pengukuran Neutron Porosity pada sumur terbuka (Open Hole) ditujukan untuk mengukur indeks hidrogen yang terdapat pada formasi batuan. Indeks hidrogen didefinsikan sebagai rasio dari konsentrasi atom hidrogen setiap cm3 batuan terhadap kandungan air murni pada suhu 75oF.
 Neutron Porosity log tidaklah mengukur porositas sesungguhnya dari batuan, melainkan yang diukur adalah kandungan hidrogen yang terdapat pada pori-pori batuan. Secara sederhana, semakin berpori batuan semakin banyak kandungan hidrogen dan semakin tinggi indeks hidrogen. Sehingga, shale yang banyak mengandung hidrogen dap

Abstract:
In production wells, nuclear-physical and electrical logging methods are used to study the backwater space. More well-known and widespread is pulsed neutron logging (PNL) [16] and its modifications. Electric divergent logging (EDC) is considered less common [2] in cased wells. Both methods solve the same problem, but they are still not ideal and have their drawbacks. This article presents the advantages and disadvantages of the PNL and EDC methods in comparison with each other. A significant criterion when choosing the preferred method for determining the current oil and gas saturation is the

Carbon dioxide injection to improve oil recovery is an important link in carbon capture, utilization, and storage (CCUS) and an important means of tertiary oil recovery. Conducting gas injection profile logging in injection wells can reflect the inter-and intra-layer suction differences in gas injection wells, reveal the contradictions between injection and production, and provide a basis for gas plugging and profile control; The integrity of the wellbore is an important part of the storage stage of CCUS, which directly determines the burial and storage effect, and wellbore leakage directly af

Abstract:
As neutron detectors, 3He proportional counters have generally been used in security, environmental monitoring, medicine, and well-logging fields. The 3He is a product produced during β-decay of 3H. The 3H has generally been used in nuclear weapons, and the supply of 3He decreased due to nuclear disarmament and prohibition of nuclear experiment. However, the demand of the neutron detectors rapidly became high in the security field after September 11th terrorist attacks in 2001, and the demand of 3He became higher than the supply. Therefore, scintillators for neutron detection have been require

Abstract:
Abstract Density, Pe, and neutron-porosity measurements made while drilling are extremely sensitive to the distance between the sensors and the borehole wall (standoff). To minimize these effects, an ultrasonic transducer is positioned collinearly with the nuclear sensors. Rapid pulsing of the transducer provides frequent measurements of the standoff. These measurements are used to average the nuclear data in a manner that emphasizes the smallest standoff data. This greatly improves the quality of the density, Pe, and neutron-porosity logs. Additionally, the standoff measurements are used to c

Abstract:
With the increasing demand for oil and gas exploration, the reason for sidetracking an existing well is to restore or increase the production of an existing well quickly and economically. As basic reservoir parameters, porosity and oil saturation are essential for the real-time formation evaluation in sidetracking wells. Traditional neutron-porosity logging using an Am-Be neutron source and two He-3 detectors has been widely applied in oil and gas exploration. Thus, the Am-Be logging source has been replaced either with a D-T neutron generator or a Cf-252 source to reduce the potential for vul
