Abstract
In Indonesia, people have long produced Eichhronia Crassipes Plant (ECP) stalks as raw materials for handicraft products. Other research has demonstrated that the tensile testing of individual fibres provides relevant data to assess their integrity in drilling muds. Whilst data on the mechanical properties of other natural fibres used as lost circulation material in drilling muds have been collected, the behaviour of ECP is unknown.
This study proposes an alternative solution to combat the vast growth of this invasive species through utilising it as lost circulation material for oil and gas drilling operations. The plant fragments studied originated from plant stalks and were extracted as individual fibres.
The study describes tensile tests to characterise stiffness and strength. Mechanical tests were conducted on ECP fibres to determine their stiffness under dried and water-wet conditions.
Initial tensile tests on nylon fibre determined potential experimental artefacts with the experimental approach. The dried fibres had a water content of 8.163 wt. % (SE 0.636), whereas the wet fibres were 93.43 wt.% (SE 0.294).
Water wet fibres had a lower modulus of elasticity than dried fibres and therefore, dried fibres have less tensile strength than wet fibres (Mean = 45.16 MPa- SE = 5.023- N = 41)
