Well testing involves carrying out investigation to ascertain the condition of a well which is intended for further production. These tests are carried out at various stages of life of the well to detect well problems which affect the productivity of a well. It simply involves measuring the parameter affecting a well and how these parameters changes with time. This is then used to predict the future performance of the well and how to best enhanced such performance. It is pertinent to carry out test on well for efficient management of the well and to be able to make better decisions as regards field operations. Several well problems such as damaged permeability, skin effect, coning problem, reduction in pressure, etc. affect the productivity of a well. The research work was carried out to determine the problems associated with a well whose history was given. The given well data was used with mathematical models to detect the state or condition of the well. Several factors affecting the life of the well were computed and these were used to improve the productivity of well From analysis of the well test data, it was seen that the well had impairment which was due to reduced permeability and thus, required stimulation for improved recovery of the hydrocarbons present. Also, there was high sand and water production which also reduced the productivity of the well. Matrix acidizing and hydraulic fracturing are two suitable stimulation methods suitable for improving the well recovery
