RESERVOIR MANAGEMENT STUDIES
In line with Laser’s Quality policy, the quality objective of the Reservoir Management department is to render quality services within our scope always while adhering to industry standards applicable. We carryout comprehensive reservoir studies leading to optimal field development plans for asset management purposes for major and marginal field operators. Our studies encompass the use of classical and special geological and reservoir engineering analysis. We also employ the use of analytical geological and engineering tools, as well as static and dynamic numerical modelling tools. Our consultancy can be in form of reservoir studies, asset management, provision of skilled manpower and software.
Laser is also involved in Asset Management Consultancy. It has been our experience that most operators who commission field studies do not often have skilled personnel who properly understand the results of the field studies, let alone implement them. This is even more so as the operators hardly have enough of their own technical personnel as part of the study team, in studies undertaken by third party organizations. The result is a gap between the study and implementation of its results. This shortfall is what Laser’s asset management consultancy covers.
In Asset Management Consultancy, Laser supplies a team of skilled geoscientists and engineers who function as core reservoir management professionals in the Asset Management Teams of major and marginal field operators.
