INTELLIGENT PRODUCTION ENHANCEMENT TECHNOLOGY: DESIGN AND DEVELOPMENT - Sell Project

ABSTRACT In the production process of oil & gas reservoirs; the wellbore plugging due to sand accumulation has been an inevitable issue. Similarly propant flowback and particulate settling in or near the wellbore has the effect of degrading the production and resulting in a sick/dead well if proper care has not been taken in time. In this project (LIVE) the prime objective is concerned with such an issue, where in an area (Mansa) three adjacent wells (# 36, #39, #40) have been set for production; but with time only the well #36 is producing on a daily basis and rest two once in 4-5 days. Thus, in this project, efforts have been made to find out the factors for such low and irregular production and suitable subsequent remedial technology for production enhancement through proper design and development. The production challenge being faced in wells MNS#39 & MNS#40 are thus has to be identified and a suitable enhancement technology has to be adopted. This requires the sub-surface data of the Mansa area of Mehsana Block, Gujarat; where the two wells of ONGC numbered as #39 & #40 are unproductive while another adjacent is well productive on regular basis, though being located in same formation. Thus it has to be taken care of the mineralogy of the formation and prediction of the settling criteria of the particulates if any and their flow dynamics. After identification of such mineralogy the wells can be provisioned with properly designed flush or circulation fluid through tubing and the wellbore, which would possibly result in improving the production rate and flow geometry.
