Abstract
A fluid flow model is comprised of one cross-flow style core holder and a multitude of standard style core holders, all connected by a concurrent combination of serial and parallel flow paths. The sum of these flow paths yields a fluid flow model that closely approximates a small radial slice of a conventional reservoir. The fluid flow model has particular applicability to estimate the requisite treatment fluid for use in acidizing as well as water control methods.
Claims26
A fluid flow model comprising:
- (a) a primary core zone;
- (b) a secondary core zone comprising at least two secondary cores;
- and
- (c) a tertiary core zone comprising at least two tertiary cores for each secondary core
- wherein each of the cores in the primary core zone, secondary core zone and tertiary core zone is connected by a combination of serial and parallel flow paths.
A fluid flow model comprising:
- (a) a primary core zone comprising a cross-flow core holder;
- (b) a secondary core zone comprising at least two core holders;
- and
- (c) a tertiary core zone comprising greater than two core holders wherein each of the core holders in the primary core zone, secondary core zone and tertiary core zone is connected by a combination of serial and parallel flow paths.
A method of estimating the requisite volume of treatment fluid for a reservoir which comprises:
- (a) introducing a fluid into a primary core zone containing a primary core and allowing the fluid to flow through the primary core and leak material through the primary core by means of a cross-flow core holder;
- (b) injecting a treatment fluid into a primary core zone and permitting the treatment fluid to travel through and exit from the primary core;
- (c) partitioning the primary core exit fluid into at least two streams;
- (d) introducing the partitioned primary core exit fluid into a secondary core zone containing at least two secondary cores and permitting the fluid to travel through each of the secondary cores and exit there from;
- (e) partitioning the secondary core exit fluid from at least one of the secondary cores into at least two streams;
- (f) introducing the partitioned secondary core exit fluid into a tertiary core zone containing at least two tertiary cores;
- and
- (g) estimating the total volume of treatment fluid needed to flow from each of the primary, secondary and tertiary core zones.
A fluid flow model comprising:
- (a) a primary core having a cross-flow primary core holder of specified inner diameter;
- (b) a secondary core zone having a secondary core holder of inner diameter greater than the specified inner diameter of the primary core holder;
- and
- (c) a tertiary core zone having a tertiary core holder of inner diameter greater than the inner diameter of the secondary core holder
- wherein the primary core holder is connected by a serial flow path to the secondary core holder and further wherein the secondary core holder is connected by a serial flow path to the tertiary core holder.
