oa Production of thick crude through concentric coiled tubing

The drilling of exploration wells in thick Oil reservoirs has proven to be a major challenge for Oman Operator when it came to establish the presence of Oil in these wells. Traditional method consisted of using Nitrogen lifting to recover the oil, but this has proven to be very uneconomical option due to the extremely low pressure reservoirs. The option to recover the fluids using Beam pumps out of these low pressure/ high viscosity wells is possible, but as these wells are under exploration program, the client needs to assess the presence of Oil first before committing to bring in Beam pump/ PCP.
