In one version, two systems are mounted on the skid, one system being a single well system for testing various properties of well fluids, and the other being a combined bulk system for desanding comingled flow from a plurality of wells. In another version, the skid mounted system has three independent desanders together with all essential equipment, including e.g., plug catcher, hydrocyclone desander, solids accumulator, choke manifold, and all necessary sensors, valving and control equipment. ## Claims ### Claim 1 A portable hydrocarbon desanding system for desanding production fluids from multiple wellheads, said system comprising a movable skid base on which is affixed at least two independent desander systems, each independent desander system comprising the following elements: a) inlet piping for receiving a slurry comprising oil, water, gas and solids directly from a wellhead of a hydrocarbon well; b) said inlet piping fluidly connected to an optional plug catcher and thence to an inlet of a hydrocyclone desander; c) said desander being fluidly coupled to a solids accumulator; d) said solids accumulator having a solid discharge outlet; e) said desander having a cleaned fluid discharge outlet; f) said cleaned fluid discharge outlet being fluidly connected to a choke manifold that is fluidly connected to a central processing facility (CPF); wherein said skid base has two independent desander systems—a first desander system being a test desander system for desanding a slurry from a single well, and a second bulk desander system for desanding a comingled slurry from more than one well. ### Claim 2 (depends on 1) The system of claim 1, wherein said desander and said solids accumulator are integral. ### Claim 3 (depends on 1) The system of claim 1, wherein said desander is a hydrocyclone desander. ### Claim 4 (depends on 1) The system of claim 1, wherein said desander is a flooded core hydrocyclone desander. ### Claim 5 (depends on 1) The system of claim 1, wherein said choke is an automated choke manifold. ### Claim 6 (depends on 1) The system of claim 1, wherein said desander is a high pressure hydrocyclone desander. ### Claim 7 (depends on 6) The system of claim 6, further comprising a low pressure desander mounted on said skid. ### Claim 8 (depends on 6) The system of claim 6, further comprising a low pressure desander downstream of said choke manifold and upstream of said CPF. ### Claim 9 A portable hydrocarbon desanding system for multiple wellhead use, said system comprising: a) a movable skid base on which is affixed: i) a first desander system being a test desander system for desanding a flow from a single well; and ii) a second desander system for desanding a comingled flow from more than one well; b) wherein a plurality of wells at a well-pad are fluidly connected to both said first desander system and to said second desander system; c) wherein each desander system comprises the following elements: i) inlet piping for receiving a slurry comprising oil, water, gas and solids from a well; ii) said inlet piping fluidly connected to an optional plug catcher for trapping large debris from said slurry and then to an inlet of a desander; iii) said desander being fluidly coupled to an integral solids accumulator; iv) said solids accumulator having a solid discharge outlet; v) said desander having a cleaned fluid discharge outlet; vi) said cleaned fluid discharge outlet being fluidly connected to a choke manifold; and vii) said system further comprising one or more emergency shut off valve(s); d) wherein said cleaned fluid discharge outlet from said first desander system is fluidly connected to a testing system for testing one or more properties of said cleaned fluid, and thereafter is fluidly connected to a separate CPF; and e) wherein said cleaned fluid discharge outlet from said second desander system is fluidly connected to said separate CPF. ### Claim 10 (depends on 9) The system of claim 9, wherein said testing system comprises an oil meter, a gas meter and a water meter. ### Claim 11 (depends on 9) The system of claim 9, wherein said testing system is mounted on said skid. ### Claim 12 (depends on 9) The system of claim 9, wherein each said desander is a flooded core hydrocyclone desander. ### Claim 13 (depends on 9) The system of claim 9, wherein each said desander is a high pressure flooded core hydrocyclone desander. ### Claim 14 (depends on 13) The system of claim 13, further comprising a low pressure desander downstream of said high pressure flooded core hydrocyclone desander. ### Claim 15 (depends on 9) The system of claim 9, wherein said choke manifold is an automated choke manifold. ### Claim 16 (depends on 9) The system of claim 9, wherein the one or more properties of said cleaned fluid include a percentage of oil, gas and water.
