MagniSphere

MagniSphere™ high-definition NMR logging-while-drilling service delivers real-time, lithology-independent formation evaluation while drilling, enabling confident reservoir characterization in complex environments. The service provides direct insight into pore structure, fluid distribution, and producibility in real time. MagniSphere service acquires high-quality NMR measurements under dynamic drilling conditions, including simultaneous T₁ and T₂ relaxation information to deliver accurate porosity, permeability indicators, bound fluid volume, free fluid volume, and rock typing in both clastic and carbonate reservoirs. High-definition relaxation maps improve fluid identification, saturation evaluation, and reservoir quality assessment in heterogeneous, laminated, and thin-bed formations. By integrating real-time NMR answer products into reservoir workflows, the MagniSphere service reduces uncertainty, improves well placement, and enhances reservoir understanding, supporting optimized drilling, completion, and production decisions directly at the wellsite.
