Methane hydrate has been received large attention as a new energy source instead of oil and fossil fuel. However, there is high potential for geomechanical stability problems such as marine landslides, seafloor subsidence, and large volume contraction in the hydrate-bearing sediment during gas production induced by depressurization. In this study, a thermal-hydraulic-mechanical coupled numerical analysis is conducted to simulate methane gas production from the hydrate deposits in the Ulleung basin, East Sea, Korea. The field-scale axisymmetric model incorporates the physical processes of hydrate dissociation, pore fluid flow, thermal changes (i.e., latent heat, conduction and advection), and geomechanical behaviors of the hydrate-bearing sediment. During depressurization, deformation of sediments around the production well is generated by the effective stress transformed from the pore pressure difference in the depressurized region. This tendency becomes more pronounced due to the stiffness decrease of hydrate-bearing sediments which is caused by hydrate dissociation.

We consider modeling and geophysical interpretation of the obtained results in the oil and gas production problems. For solving these practical problems, we use combined finite element-differences method of resolving piezoconductivity problem with calculation of heterogeneous filtration parameters distribution of oil and gas productive reservoirs and oil-gas penetration conditions in the borders of the reservoirs. At that, we consider the main factors, which influence on the intensity of filtration processes near oil production well and gas production well respectively. These factors are important for effective supporting in practice high level of the oil and gas production. On the base of computer modeling, we have showed that intensity of filtration process near the acting oil and gas production wells mainly depends on oil phase and respectively gas phase permeability, as in close zone of well acting so in remote zone. The viscosity and reservoir porosity parameters in close and remote zones of the well action have little direct effect on filtration process near the acting well. However, these parameters can influence on the filtration process implicitly via direct acting on the respective phase permeability. We also have carried out analysis of the pumping well influence on the filtration process near production well in different practical cases.

Effective Doses

Abstract An oil and gas production facility in the western desert of Egypt was investigated for possible radiation risks due to the routine operation. Radium-226, Radium-228 and Potassium-40 were assessed in the soil samples collected from the adjacent soakaway pond. The average 226Ra, 228Ra and 40K activity concentrations were 881.0 ± 42.0, 966.0 ± 43.0 and 143.0 ± 8.0 Bq kg−1, respectively. Both 226Ra and 228Ra were above the world ranges, while 40K was within the world range. Water samples from the facilities effluent’s produced water showed elevated levels of both radium isotopes. The effective doses at three different points on the separator outer surfaces over the period between 1995 and 2014 were assessed. The maximum reading was 5.4 μSv h−1 on 2014. The time has significantly contributed to the enhancement of the effective dose readings. However, they are still within the expected range encountered in similar studies reported by International Atomic Energy Agency (IAEA).

Development Plans

Akkas gas field is the biggest natural gas field in Iraq that is located in the western desert area. The field contains around (9 BSCF) of approved gas reserve from the conventional rock source. This paper presents field development planning process combined with economic analysis comprises, the number of wells that yields in maximum net present value (NPV), the recovery factor and raw gas production rates for the total number of suggested wells that have been estimated, as well as the cumulative gas produced with time. The development plans were elaborated concerning different types of well geometries and operational constraints. Full comparison analysis for all presented plans regarding NPV, recovery factor, discounted cash flow versus production time, forecasted production rate, as well as forecasted cumulative production with time have been presented. Sensitivity analysis has been made to determine well and reservoir controlling parameters that leads for best operating field development plans. The study shows the effectiveness of horizontal well type compared with vertical wells; as well as, the effect of reservoir permeability on field development plans, the results show that the field could be operated at target plateau rates of (250, 500 and 750 MMSCF/D). It also shows the superior effect of stimulation processes in increasing the NPV and field recovery factor using less number of wells

Abstract As China’s offshore drilling and production projects gradually march into the deep water, the requirements for scientific and technological progress are imminent. The occurrence of the 2010 Macondo disaster has presented a serious challenge to the safety of deepwater in technology. The deepwater wellbore consists of several layers/channel barriers, which constitute the wellbore barrier system and have a complicated structure. With the increase of water depth and well depth, the temperature of oil and gas produced at the wellhead is getting higher and higher, and the fluid in the annulus of the casing is heated by the conduction and convection of fluids such as oil and gas produced in the high temperature formation. Up to 60 degrees Celsius, the thermal expansion of the annulus fluid can cause the casing to burst, which can cause significant loss of personnel and property. Therefore, accurate temperature calculation of deep water wellbore is the key to the calculation of trap pressure prediction. The calculation of the wellbore temperature is affected by the oil casing and the thermophysical parameters such as the size of the wellbore, fluid composition, flow regime, casing and cementing sheave. By appropriately simplifying the model and sensitivity analysis, it is found out the dominant factors which affect the temperature profile.
