Owing to its strong adaptability and flexibility, gas lift is widely used in deliquification or production restoration for water-flooded gas well. This paper briefly introduced the advantages and adaptability of the gas-lift hard lift technology (gas lift without gas lift valve). The mathematical model based on the mass and momentum conservation was established to describe the unloading process of gas-lift hard lift and... Read more.

Radial jet drilling (RJD) is an unconventional drilling technique that uses the jet energy of high velocity fluids to drill laterals with different geometries in both conventional and unconventional reservoirs. Many case studies available worldwide have proven RJD as a viable alternative to traditional stimulation techniques, especially in marginal fields. RJD has a lot of application in the oil and gas industry. It is... Read more.

Fundamentally, all mathematical models employed in analysis of water-flooding performance implied assumptions to exclude one or more forces to cope with the reservoir heterogeneity. In the beginning of the survey, a series of sensitivity investigations were undertaken to examine the parameters that affect the water-flooding performance in stratified reservoirs. The factors were designed to measure the impact of each... Read more.

Sand production is a prevalent problem during oil and gas production from weakly consolidated or unconsolidated formations. It can erode downhole equipment and surface facilities, cause pipeline blockage, leakage and damage casing and generate additional need for sand disposal. Decision for appropriate sand control strategy requires engineering analysis of the key parameters affecting sand production to evaluate timing... Read more.

Recovery factor for gas reservoirs are highly dependent on factors such as initial reservoir pressure, abandonment pressure and the type of reservoir drive mechanism. Producing gas reservoirs with active water drive mechanism possess a lot of challenge to the field operator since optimum production of gas is dependent on reduced pressure. Material balance model was used to derive basic reservoir and production... Read more.

Fractured carbonated reservoir is one type of unconventional reservoirs which has low permeability rather than conventional reservoirs in terms of complex depositional and diagenetic environment. In most of the fractured carbonated reservoirs, fluid flow characteristics such as permeability and porosity are generally difficult to estimate and the most porous intervals are not always the best reservoirs as the intervals...

Sand production is a major concern during petroleum exploitation from unconsolidated sandstone reservoirs. For efficient management, sanding predictive tools are necessary. While several models have been developed for sanding in oil reservoirs, gas and gas condensate reservoirs have received little attention because of the widespread belief that such reservoirs are not prone to sanding. This study utilized erosional... Read more.

The drilling operation cost represents 25% of the total oilfield exploitation cost. Drilling fluids represent 15 to 18% of the total cost of well petroleum drilling operations. The main drilling fluids problem is the loss into fractures and vugs. Mitigation of severe lost circulation is a main challenge while drilling in fractured formations where conventional lost circulation materials (LCM) will not cure these losses.... Read more.

This work aims to characterize petrographically some of the transition zone plug samples in order to understand the impact of diagenetic processes on the transition zone rock quality. Three carbonate samples were collected from the same well which cuts through a thick transition zone of a heterogeneous cyclic carbonate reservoir of Abu Dhabi with respect to depth. The petrographic analysis was conducted by the thin... Read more.

During polymer flooding, the behaviors of water injection profile reflect the flooding efficiency and its performance in medium and low permeable layers represents the sweep efficiency of the reservoir. In this work, the polymer flooding wells in Bohai Oilfield is analyzed and the observations on the performance are, with more polymer injected, the injection profile is characterized by: In most of the wells, vertically,...

Conventional drilling fluids such as diesel and mineral oil have posed some environmental and health challenges in their drilling applications but the introduction of synthetic-base fluids over the past two decades has considerably reduced such challenges. In some cases, a bottom hole temperature above 300°F (150°C) can cause significant instability in the rheological properties of these drilling fluids.... Read more.

During the history matching, attentions are shifted from the structural map and focus are on the dynamic properties such as relative permeability data, saturation end points and Pressure-Volume-Temperature (PVT) information. However, structural maps can inherit huge uncertainty which can affect the dynamic behaviour of the reservoir. The objective of this study is the presentation of an approach for quantifying...

In this study, we develop a Galerkin-type finite element (FE) solution to assess the creep deformation of fracture surfaces. These surfaces are treated as comparatively compliant rocks which are separated by a comparatively stiff proppant pack. Viscoelastic properties of fracture surfaces are assessed by the temperature and deformation dependent modulus. The key challenge is to appropriately develop the creep and the... Read more.

The research sets about describing the different oil types in the South Sumatra Basin and relating the hydrocarbon to source rocks. Four different groups of oil have been identified; the character of the oils suggests both lacustrine and terrestrial input to the source rocks. Type 1 oils have marine/lacustrine influenced (low pristane/phytane), Type 2 are terrestrially derived (high pristane/phytane ratio), Type 3 are... Read more.

Often students of the petroleum engineering programs at the early stage of their studies in institutions of developing countries do not have easy access to the oil and gas industry facilities. Multinational petroleum companies come in with the state-of-the-arts technology, with expatriates who work and leave without technology transfer. Laboratory equipment is very costly to developing institutions of petroleum studies... Read more.

Natural gas hydrate (NGH) technology is a feasible alternative to capture associated-gas, which are usually difficult to harness in the stranded and/or marginal oil field. The importance of gas hydrates is related to its potential to be able to contain about 160 Sm3 of gas and 0.85 m3 of water in 1 m3 of gas hydrate at standard temperature and pressure. This feature of natural gas hydrate can be brought to bear in... Read more.

In the Niger Delta, low oil recovery rates less than 30% results mainly due to oil production problems such as water coning, wax deposition and high gas/oil ratios. Meanwhile, the remaining oil becomes a good candidate for EOR methods such as CO2 injection, polymer and foam injection, in-situ combustion and steam injection. But as it stands, the practice of these known methods of enhanced oil recovery is scarce in the... Read more.

Presently, low salinity waterflooding is considered one of the most promising and cost-effective EOR methods. Although the recovery mechanisms are still uncertain, decrease of residual oil saturation and alternation of rock wettability are considered to be main mechanisms of the incremental oil recovery. In addition, laboratory and mathematical studies conducted over recent years suggested that mobility control is also... Read more.

Understanding the behaviour of pressure distribution completed in two layered reservoir subject to both active gas cap and bottom water drive mechanisms is very important in reservoir management. To determine the factors that affect pressure distribution of horizontal wells in a layered reservoir subjected simultaneously with a gas-cap at the top and bottom water drives, well completion was carried out in a particular...
