ICD completion has been rapidly developed due to its effective mitigation of unwanted water breakthrough in horizontal wells. It prolongs the no-water production time by introducing an extra pressure drop in high inflow rate zones. With respect to the horizontal well, equally distributed influx is generally regarded as the ideal influx to achieve the longest no-water production period. Howeverin some cases, like producing with fixed bottom-hole pressure (BHP), this may not always correct. When designing the ICD completion, the target inflow profile should be carefully selected. The horizontal well needs to be selectively completed with variable ICDs to minimize the reduction of well productivity.In this paper, a reservoir-wellbore coupling model will be given for influx computation, in which the ICD pressure drop is considered. Then we will propose the selection principle of the target inflow profile for ICD optimization on the constraints of BHP limits, required daily production and no-water production periods. The cumulative production at the time of water breakthrough is selected as the evaluation criteria. The flowchart of the ICD optimization process for the heterogeneous reservoir will be illustrated; and a synthetic case study will be carried out with a comparison of open-hole completion, constant ICD completion and optimal ICD completion. Results indicate that the effect of the water control of ICD completion can be maximized with a reasonable selection of the target inflow profile.

TX 75083-3836, U.S.A., fax +1-972-952-9435. AbstractThe best well completion is the lowest cost one that meets the demands for the well during its life time. There are different aspects that we need to consider when designing completion such as reservoir consideration (Allen and Roberts, 2006).We can have openhole completions, perforated casing completion, or horizontal completions. In this study, we present lab evaluation of oil and water swelling elastomers for potential field application in Saudi Arabia fields.Oil and water swelling packers were examined in the lab (measuring pressure difference across swelling packers in autoclaves at 190°F and testing against various salinity fluids and pH using coupons at 190°F). Crude oils with various properties were used to test the oil swelling packers. Water swelling packers were tested in aqueous fluids with various pH values and salinities.Oil swelling packers showed acceptable pressure drops across the packer for six crude oils. They were resistance against acids and different brines. Oil swelled elastomers were tested with different salinity fluids to simulate the effect of produced water on the oil swelling packers. They were also tested against various acids to simulate possible stimulation treatments. The water swelling packers showed acceptable results for all fluids tested except at high and low pH fluids. This limits their use in wells with potential acid treatments.Oil swelling packers were used successfully in 16 oil producers. Cost saving on the rig time was achieved with swelling packers to cased-hole completions. Up to 22% of the rig time was saved due to the elimination of running casing, cementing, using whipstock and casing milling. To date, all wells completed with oil swelling packers are showing good results for close to three years.

“…PICDs are developed with different flow resistance ratings (FRR), which indicates the pressure drop achieved with the PICD using a defined fluid density and viscosity as well as the flow rate (Alkhelaiwi and Davies, 2007;Garcia et al, 2009). Three major PICDs: Hybrid, hellicalchannel PICDs use the friction whereas the orifice/nozlzle type PICD use fluid restriction to generate the pressure drop.…”

Advances in Modeling of Passive Inflow Control Devices Help Optimizing Horizontal Well Completions

Passive Inflow Control Devices (PICD) has become a frequently used completion method for horizontal and closeto-horizontal wells over the past decade. There are several types of PICDs, but the working principle is similar for all of them: PICD restricts a flow by creating an additional pressure drop and therefore equalizing the wellbore pressure drop to accomplish a uniformly distributed flow along the horizontal well.To evaluate performance and potential benefits of a PICD completion, a full-field simulation model is required. Simple near-wellbore simulators are often used to initially evaluate the applicability of the PICD-based completion. However, only full-field reservoir simulation can provide prediction for the completion/reservoir performance and thus allow for a full evaluation of the economics and feasibility of the project. A multi-segment well model can be used to represent the PICDs in the horizontal well. The multi-segment well model is an advanced well modeling that allows accurate modeling of multi-phase flow and pressure variations in wells with a reservoir simulation model. This paper provides an example of the reservoir development study. PICD completion is designed and optimized to achieve the best possible economic results using in a commercial black oil simulator. The work is based both on a generic model. The methodology of implementing external pressure drop models is presented. Also, the process of optimization of the PICD-based horizontal well completions utilizing simulation is shown.
