Improving Hole Cleaning using Low Density Polyethylene Beads at Different Mud Circulation Rates in Different Hole Angles
(Journal of Natural Gas Science and Engineering, 2019)
In oil and gas exploration and development, drilling a hole is one of the first and most expensive operations. The continuous demand from industry to reduce costs and operational problems has resulted in numerous innovative ...
A Critical review of Low Salinity Water Flooding: Mechanism, Laboratory and Field Application
(Journal of Molecular Liquids, 2019)
Low-salinity water flooding (LSW) is a promising new technique for enhancing oil recovery (EOR) in both sandstone and carbonate reservoirs. The potential of LSW has drawn the attention of the oil industry in the past decade. ...
Improving the Performance of Oil Based Mud and Water Based Mud in a High Temperature Hole using Nanosilica Nanoparticles
(Colloids and surfaces A: physicochemical and engineering aspects, 2019)
Oil-based mud (OBM), a non-Newtonian fluid, is known for its superior performance in drilling complex wells as well as combating potential drilling complications. However, the good performance may degrade under certain ...
Experimental Investigation of the Effect of Drill Pipe Rotation on Improving Hole Cleaning using Water-based Mud Enriched with Polypropylene Beads in Vertical and Horizontal Wellbores
(Journal of Petroleum Science and Engineering, 2019)
Field experience has shown that the inefficient transport of small cuttings is a main factor contributing to excessive drag and torque during the drilling of a deviated hole; however, very little is known about the transport ...
A comprehensive investigation on the performance of durian rind as a lost circulation material in water based drilling mud
(Petroleum, 2019)
Oil and gas operators worldwide are expecting service companies to deliver integrated techniques to minimize, if not prevent, drilling problems. Drilling fluids perform vital functions to ensure the success of drilling ...
Effect of Wettability on Oil Recovery and breakthrough Time for Immiscible Gas Flooding
(Petroleum Science and Technology, 2016)
The effect of wettability on oil recovery at higher water saturation is still not fully understood, especially in the case of mixed wettability. This study was conducted to examine the effects of wettability on oil recovery ...
Performance of Polyethylene and Polypropylene Beads towards Drill Cuttings Transportation in Horizontal Wellbore
(Journal of Petroleum Science and Engineering, 2018)
Drilled cuttings removal is critical in drilling operations, especially in horizontal wells. These cuttings are postulated to be among the possible causes of many costly complications, such as mechanical pipe sticking, ...
The Effect of WAG Ratio and Oil Density on Oil Recovery by Immiscible Water Alternating Gas Flooding
(American Journal of Science and Technology, 2017)
An Enhanced Oil Recovery (EOR) method named Immiscible Water-Alternating-Gas (IWAG) is one of the well-established methods for improving oil recovery in reservoirs. IWAG injection combines both improved displacement ...
Formulation of Surfactants from Coconut Coir Containing Lignosulfonate for Surfactant - Polymer Flooding
(American Journal of Science and Technology, 2016)
Interfacial tension (IFT) reduction between oil and water using surfactants has been used to recover trapped oil after the primary and secondary recovery, however petroleum based surfactants are costly. More research in ...
Experimental Investigation of Cuttings Lifting Efficiency Using Low and High Density Polyethylene Beads in Different Hole Angles
(J Mater Sci Appl, 2017)
This study investigates the impact of low and high density polyethylene beads on wellbore cleaning using water-based mud at different hole angles of 0°, 60°, and 90°. The polyethylene beads concertation is varied from 1 ...
